Fruit Flies and Personal Space

 images

In one of the episodes of his popular 1990’s comedy show, Jerry Seinfeld featured a “close talker”: an overly friendly person who stands just a little too close to people when he talks with them.  Although Seinfeld was able to squeeze a lot of humor from the subject, real-life “close talkers” tend to suffer from damage to their amygdala, the region of the brain which is highly involved in the regulation of emotions.  People and rats with damaged amygdalas don’t just have difficulty with personal space, they also lose all sense of caution, failing to pick up on common indications of fear or aggression in others.

A new study of fruit flies has revealed  another detail about the regulation of personal space, and it has to do with the neurotransmitter dopamine.  Anne F. Simon of Western University found that fruit flies with too much dopamine preferred to group themselves close together, while those with little dopamine needed more social space.   For humans who struggle with personal boundaries, such as those with schizophrenia or autism, this research is particularly illuminating, and offers hope for greater understanding.

Dopamine has already been implicated in human studies of introversion and extroversion. In these studies, fMRIs were used to monitor brain activity during different social situations. They found that while the nervous systems of extroverts were more energized by large amounts of dopamine, the nervous systems of introverts were over-stimulated.

Apparently, it is not quantity of dopamine in the brain that determines introversion or extroversion, but the way the nervous system responds to it.  It follows, then, that if you’re an extrovert and you have a nervous system that responds well to dopamine, you will probably also be comfortable with close personal contact.

The next time you’re at a social gathering and someone either stands or sits a little too close to you, you needn’t take it personally.  Just understand that this is probably a reaction to large amounts of dopamine affecting his amygdala, and then, let it go.  🙂

Concerns About Tattoo Ink

 

tattoo

Humans have used tattoos for centuries to advertise group membership or social status.  Older forms of tattoo appeared to have been more therapeutic.  Archeologists surmise that the web-like tattoos drawn on the abdomens and breasts of female, Egyptian women were meant to protect against miscarriage.  The mysterious dots and crosses found on the lower spine, knee and ankle joints of the world famous “Ice Man”, are speculated to have been a medicinal treatment for joint pain.  As the Ice Man is a 5,200 year old frozen mummy, he is currently the oldest human ever known to have been tattooed.

In this century, tattoo art was particularly used among prison inmates in previous decades, but there has been a popular resurgence of tattoo art among the Millennial generation.   What hasn’t been investigated, until now, is the safety of tattoos.  Modern tattoo parlours know to use sterile needles as a preventative measure against the transmission of blood-borne diseases, such as hepatitis C.  But what about the ink itself?

A new study published in the journal Scientific Reports, has found that the ink used in tattoos does not stay where it is originally put.  Over time, tiny nanoparticles of tattoo ink migrate away from the tattoo itself and accumulate in lymph nodes.  Scientists discovered this while examining samples of skin and lymph nodes from six different corpses, four of which had tattoos.  The corpses with tattoos were found to have contaminants, such as titanium, in their lymph nodes, causing the nodes to enlarge.

Tattoo ink is usually comprised of organic and metal-based pigments and preservatives, but can also be contaminated with toxic impurities, like nickel, chromium, manganese and cobalt.  While there is not yet any evidence that the accumulation of these toxins is a contributing factor to any disease, it is a disturbing finding.  It means that tattoo pigments injected into the skin are picked up as “foreign bodies” and then stored, either in the skin or in lymph nodes for disposal, which means greater stress is placed on your immune system.  Those who already struggle with weak immunity, or auto-immune problems may want to exercise caution when deciding whether or not to get a tattoo.

New Thoughts about Salt

salt

Ah, salt!  We’ve had a love-hate relationship with it for decades.  We crave it endlessly.  It’s so hard to resist!  We love it so much that we don’t even notice when copious amounts are unnecessarily added to our foods to make it taste better.

Yet we also know that salt is a killer.  Too much salt raises blood pressure, contributes to kidney disease and osteoporosis, and increases water retention, causing weight gain.   So, we go easy on the potato chips, we avoid the salted nuts, and we keep the salt shaker as far away from the dinner table as possible.

But what if salt isn’t so bad for us, after all?  New research suggests that our previous understanding of salt was mistaken, and that rather than causing us to gain weight, it may actually stimulate weight loss.

As you may have learned in your human physiology class, salt and potassium must be kept properly balanced in your bloodstream.  If you eat too much salt, you’ll soon feel a corresponding urge to drink more fluids so that the excess sodium is diluted, and the delicate equilibrium between sodium and potassium in your body is maintained.  Naturally, the extra fluids you drink will cause you to urinate more frequently, thus removing the extra salt from your body.  Or so the theory goes.

New research on Russian cosmonauts has shown that this theory may now be faulty.  In a new study published in the Journal of Clinical Investigation, these Russian cosmonauts  followed three different diets, each for 28 days.  The first was a high salt diet, followed by a moderate salt diet, and finally a reduced salt diet.  Other than the changes in salt intake, the rest of the diet was exactly the same, including the total calorie count.

Surprisingly, when eating high salt diet, the cosmonauts did not feel a corresponding urge to drink more fluids.  In fact, the saltier their diet, the less fluid they drank, even while their urinary output continued to increase.  The researchers were confused.  Where was the extra fluid coming from?  On the high salt diet, the cosmonauts also reported feeling more hunger, despite getting the same amount of calories as on the other two diets.

Urine samples showed an increase in glucocorticoids, known to raise metabolism, among other things.  It appears that as the amount of sodium in their diet increased, increased glucocorticoid production resulted in the breakdown of their fat and muscle to free extra water for their bodies to use.  In short, the high salt diet caused them burn more calories, and lose weight.  In repeat studies done on mice, a high salt diet required the mice to eat 25% more food just to maintain their current body weight.

Before you rush over to the cupboard to binge on the saltiest food you can find, consider what kind of weight was being lost on the high salt diet.  Primarily, it was muscle mass.  As eager as you may be to lose weight, I think we can all agree that muscle mass is not something we’d like to lose.  Additionally, high glucocorticoid production is linked to an increased risk of stroke and cardiovascular disease, so while it may work, this particular method of weight loss is not a very healthy one.  Scientists also noted that this breakdown in muscle mass is exactly what happens when your body enters starvation mode.

So, I think we’ll continue to keep the salt shaker at a distance for now.  The findings in this study were so unexpected, so revolutionary, that even the scientists aren’t sure what to recommend.  It is a good reminder to keep investigating, always.  In recent years, all sorts of dietary theories seem to have fallen by the wayside.  In the end, I think the best maxim is still the oldest one: “everything in moderation; nothing to excess”.

Resilience in Mid-Life

red-hair

I dyed my hair red a few years ago.  It was uncharacteristic of me.  I’m an introvert, so I don’t generally like flashy displays of colour.  So, why did I suddenly feel the urge to dye my hair red?

As I look back now, it seems clear that I was experiencing a standard mid-life crisis.  There was a well of anger building in me that I was struggling to contain.  Thus far, I’d spent my life in service to others – my husband, my children, my in-laws, my parents.  While the demands of my children were lessening, those of my parents and my in-laws were increasing, and I was tired of fulfilling all the expectations of others, while failing to provide for myself.  The red hair was the outward manifestation of a primal scream I could no longer contain.

In the grand scheme of things, I suppose changing the colour of your hair is pretty mild.  Other people completely upend their lives during mid-life, divorcing their spouse, quitting their job, buying an expensive sports car and getting drunk in bars.  While radical behaviour of this sort is alarming, psychologists say it’s completely normal.

Mid-life can be extremely challenging.  There are no longer any goalposts to guide you, as, for the most part, they’ve all been crossed.  By the time you’ve entered the middle decades of your life, you’ve probably already done the marriage thing, the children thing, and the job thing, with variable degrees of success in each.  What’s left to accomplish?  A void opens up before you, and you know that if you don’t make some kind of change, you’ll continue living the same, tired life for the next twenty-odd years, with little variation to stem the boredom, and then you’ll croak.  It’s enough to make anyone a little crazy.

Yet, while this time of life can be painful, it’s a rich and important field to cross.  With old age approaching, and our health beginning to fail, it’s the last chance we have to create the life we want.  All the parts of life that have been neglected in previous decades suddenly cry out and demand immediate attention.   If this period of mid-life is precipitated by trauma, such as the death of a loved one, a divorce, or the start of a chronic illness, it can be a particularly difficult time.  Navigating it successfully can be a challenge.

It is here where our own personal store of resilience will be required to pull us through.  Luckily, even if you think you lack resilience (and trust me, you don’t), you can strengthen it.   Here are some suggestions for how to cultivate this essential life skill:

  1.  No matter how bleak your life feels at the moment, remember that you are the hero of your own story.  There’s no story worth reading that doesn’t have a crisis in the middle of it.  When you think of your life as a story, it gives you a chance to step back and look at the overall picture, rather than focusing on what is wrong with the present.
  2.   Remember past traumas in your life and remind yourself that you not only got through them, but you grew through them too.  As the saying goes, “every cloud has a silver lining”.  Past episodes of your life gained you wisdom and experience, and you will gain something from this one too.  In fact, the only way a person truly grows is through the passage of fire.  When the chaff is burned away, a pearl of great value is revealed underneath.
  3. Develop compassion for yourself and learn to love your imperfections.  You may feel that this current period of malaise is caused by a poor choice, or a failing of your character, but difficult life events usually have more than one cause.   Whatever personal failing you are focusing on today, remember that this same quality was the reason for a big success in the past.  And then, love yourself for that perceived character flaw.  Perfect people aren’t lovable or memorable, but imperfect ones are.  As a side benefit, once you develop understanding and compassion for yourself, you’ll feel it for others too.
  4. Be grateful for what you have.  No matter what you may have lost, or want desperately to change, there’s always something in your life that’s good.  Whenever I felt down as a child, my mother would say, “No matter how bad and alone you may feel, remember that you always have at least one friend”.  I always found this advice to be true.  No matter what disaster befell me, I could always look over all the people I knew and find at least one friend to be grateful for.  Although we often overlook it, all of us here in the western world have plenty more things to be thankful for, even if its only the warm bed we climb into at night, and the roof over our heads that keeps us dry.
  5.  The stress of life is inescapable and there’s no way to divorce yourself from it.  I’ve often yearned for it, but there is no magical world where everything always works out, with minimal effort.  Not only is stress a natural part of life, it’s the motive force which propels us forward.  Without physical and psychological stresses, like hunger or the fear of being fired, we’d probably just lie in bed all day.  So, rather than despair over the fact that you have stress, learn how to better manage it.  If there’s one thing I’ve learned, no one will give you a medal for pushing yourself too hard.  Learn to take breaks, like having lunch with a friend, meditating each morning, or going for a daily walk in the park, and watch as your ability to handle stress steadily improves.
  6. As you move forward with your life, don’t get stuck on short term pleasures.  This is how people drain their bank accounts, become alcoholics, and gain excess weight.  While you do need to satisfy some cravings, you’re life will only get better if you start a project that improves your happiness in the long term.  So, take an evening course, volunteer somewhere in your local community, or cultivate closer ties with your family.  These activities nourish something deeper within us – our need to be valued and loved, and are more fulfilling in the long run than a bar of chocolate.

I’ve learned over the last ten years that middle age is filled with pot holes, slippery slopes, and outright crashes.  It’s impossible to avoid them, so there’s no point in bashing yourself when they occur.   Acceptance of these facts has only come after many nights of crying, fretting and plotting.  Thankfully, I seem to be rounding the corner.  Although my hair is still red, the shade has softened.  It is my hope the suggestions here help others also struggling through this difficult time of life.

How to Increase Your Fruit and Vegetable Intake (and Why You Should)

vegetables

Your mother was right.  You should eat your vegetables!  A new study from Imperial College London has found that increasing your daily fruit and vegetable consumption to 10 servings per day (from the current five) would prevent 7.8 million premature global  deaths.

After conducting a meta-analysis of 95 different studies which looked at daily fruit and vegetable intake, eating 10 portions of fruits and vegetables a day was associated with a 24% reduced risk of heart disease, a 33% reduced risk of stroke, a 28% reduced risk of cardiovascular disease, a 13% reduced risk of total cancer, and a 31% reduction in dying prematurely.

This is all well and good, but the information will be of little use to you if you already find it difficult to eat just 5 servings of fruits and vegetables a day, as is the case for 2/3 of North Americans.

For those who struggle to increase their fruit and vegetable intake each day, here are some tips which may be of help to you:

Firstly, when preparing your meals, envision that half of your plate should be filled with vegetables.  The remaining half can be divided equally into a protein source and a carbohydrate.  Then, ensure that you cook or prepare enough vegetables so that each family member can cover half their plate with them.

Secondly, try to include a fresh fruit or vegetable with every meal and snack.  For example, instead of  eating scrambled eggs on their own, add spinach, avocado and/or tomatoes.  If you’re eating oatmeal for breakfast, sprinkle some fresh fruit over the top.  For daily snacks, prepare and eat a fruit and vegetable smoothie rather than a cookie or crackers.  Or, you can eat chopped vegetables dipped in humus.  Also under-rated:  just eat a piece of fruit.  Apples, pears and bananas are already packaged for easy transport and can easily be added into packed lunch bags.

Thirdly, one pot meals are great ways to ensure you’re eating your vegetables.  If you’re preparing a stew or a soup, be sure to add plenty of carrots, celery, spinach, kale, sweet potato, or beans.  Soups were always my favourite way to get my kids to eat vegetables when they were young.  Vegetables that they would typically shun at other times were often eaten with relish when pureed into a soup.  An added benefit of eating cooked vegetables over raw vegetables is that the heat breaks down the cellulose matrix (plant fibre) in cooked foods, making all nutrients more readily available for your body than when they are eaten in raw form.

Finally, consider yourself an artist with your meals.  If your plate contains nothing but dull browns and whites, you need to liven it up a bit.  Even if you have little time for food preparation, you still eat canned soup, frozen meals, or other prepared food.  Just be sure to add some extra colour and nutrients to them  by chopping up a red pepper, adding some parsley or spinach leaves, or stirring in a well rinsed can of beans.  This not only increases your vegetable intake, but reduces the salt content of your meal, making it more heart healthy.

Researchers are not sure what specific contents of fruits and vegetables cause the reduction in the rate of death, but they are packed with lots of nutrients.  That being said, since antioxidant or vitamin supplements that contain similar nutrients have not been shown to reduce disease risk, it’s possible that the added fibre, or something else inherent in fresh vegetables, plays a part.  In short, there’s no substitute for fresh fruit and vegetable intake.  We may all wish we could just take a pill or drink a quick liquid supplement to get all the nutrients we need, but the research shows there’s no comparison.

The fruits and vegetables shown to have the greatest influence on health include; apples, pears, citrus fruits, leafy green vegetables, beta carotene-rich vegetables such as carrots and sweet potato, and vitamin C-rich fruit and vegetables for good heart health, and broccoli, Brussels sprouts, peppers, carrots, and green beans for a reduction in cancer.

Unfortunately, it’s unlikely that this update in fruit and vegetable consumption will be reflected in official government dietary recommendations because the increased amounts are seen as unrealistic.  Officials worry that increasing dietary expectations will only lead to greater frustration, and reduced effort on the part of many individuals, particularly those who already struggle to eat five fruit and vegetable servings per day.  But if you’re up to the challenge and want to give it a try, your body will thank you with improved health and longevity.

The Amazing Heart Health of the Tsimane People

Tsimane

You ate a big meal last night while visiting friends, and may have consumed too much alcohol.  Today, you feel tired and a little light-headed.  You’re also feeling nauseous, but you hope that will go away, with time.  Suddenly, you break out in a cold sweat.   A feeling of tightness is developing in your chest, and it’s radiating down your left arm.  It’s beginning to dawn on you that you might be having a heart attack.

Heart disease is the leading cause of death for both men and women in North America and Europe, and by middle age, most people in these countries already have some signs of plaque build-up in their arteries.   Even Egyptian mummies have been found to have arterial plaque in their peripheral arteries, so scientists concluded long ago that heart disease is virtually inevitable as we age.   Eating well and exercising daily might delay the progression of arterial hardening, but nothing can stop the progression.  Or so it was thought.

The recent discovery of an Amazonian tribe in Bolivia has revolutionized this thinking and astounded all researchers involved.  A study recently published in The Lancet describes a group of Bolivian tribe people, the Tsimane, who have virtually no incidence of heart disease or stroke.  They have hardly any hardening of the arteries, and few, if any, experience heart attacks or strokes even well into old age.

A full two thirds of Tsimane men over the age of 75 have almost no arterial plaque.  In fact, the average 80 year old Tsimane man has the vascular age of an American man in his mid-50’s, and at middle age, they have the physiology of the average twenty year old.  Hands down, the Tsimane people of Bolivia have the healthiest hearts in the world, easily knocking Japanese women out of their long-held spot in first place.

How do they achieve this remarkable feat?  Researchers suspect it is a combination of diet and lifestyle factors.  Since the Tsimane live without electricity or other modern conveniences, they spend most of their days on extended hunts, or gathering berries, and take an average of 17,000 steps per day.  Even people over the age of 60 have a daily step count of more than 15,000.  They are active for more than 90% of daylight hours, and walk about 7 1/2 miles each day.  This regular physical activity is constant, but of low intensity.  It’s not that they are particularly vigorous with their activity level.  They just spend very little time sitting.

Their diet is surprisingly high in carbohydrates, a finding that calls into question recent evidence linking a high carbohydrate intake with increased risk of heart disease.  Fully 72% of the calories in the Tsimane diet come from carbohydrates, in the form of rice, plantains, manioc, and corn.  By contrast, the average western diet contains only 52% carbohydrates.  The Tsimane also eat a low fat diet, with only 14% of their calories coming from fat, compared to 34% of calories in the average western diet.  Protein sources take up 14% of the calories in both western and Tsimane diets, but the Tsimane consume more lean meat than we do, and less saturated fat.

Interestingly, the Tsimane people have high inflammatory markers, as they are almost constantly infected with parasites, including hookworm, roundworm, and giardia.  But this near-constant state of inflammation doesn’t appear to negatively affect their arterial health, as it has been thought to do in modern societies.

Nor are the Tsimane people particularly lean.  About a quarter of Tsimane adults are overweight, although none are obese.   Nevertheless, their overall lifestyle keeps their LDL cholesterol, blood pressure, and blood sugar levels very low.

So, what do we do with this information?  Is it the diet or the activity level of the Tsimane that’s most important?  Researchers suspect that one probably feeds into the other.  Perhaps the most important finding is that lifestyle has a profound influence on our heart disease risk – much more so than genetics.  Cardiologists involved with the research now agree that up to 80% of premature heart disease and stroke is preventable though lifestyle changes, so the more of the Tsimane lifestyle that you can incorporate into your own, the better.

No one wants to experience the frightening symptoms of a heart attack, or stroke.  These sudden events can drastically change our quality of life, and the lives of our family members, for the worse.  But the Tsimane have provided us with hope.  Our destiny is more firmly under our control than we may have previously thought.  We just need to act on it.

A Natural Way to Improve Sleep

camping

There is an old photo hanging on the wall in my home.  It’s a picture of my two boys clambering about in the backyard when they were both under the age of five.   Neither of them are wearing a coat, and their feet are clad in rubber boots, so you can assume the weather is warmish.  You’d think the exact time of year might be difficult to tell, yet it isn’t.   There’s something about the quality of light shining down on them that’s a dead giveaway – you know right away that the season is spring.

I’ve often looked at that photo and wondered about the changing  colours of light.   I’m fascinated by the brighter whiteness of spring light compared with the more yellow and orange shades of autumn, and I’ve wondered:  are my perceptions of light subconsciously altered by my knowledge of the time of day and the season?  Or does the colour of light really change?  How is it that you can wake up after a long nap and know, without even checking your clock, the approximate time of day?

A scientist would tell me that this isn’t a mystery at all.  The colour of light does change as the days unwind and the seasons pass, and it all depends on wave frequency.  Because of changes in the frequency of light, morning light has a predominantly  blue/green shade, making it appear substantially different to our eyes than afternoon light, which has more red/orange colour.

This may seem a largely cerebral distinction.  Who cares what colour the light is anyway?  But when it comes to our health, it matters a lot.  It matters because all of our modern devices – our computers, our smartphones, our tablets, our televisions – emit a blue-green light, which tricks our brain into thinking that it’s morning when it’s not.  This is why widespread use of electronic screens late at night has led to a scourge of sleep deprivation.

When we check and use electronic devices late at night, melatonin production in our brains is shifted by two or more hours, making it difficult for us to fall asleep at night, and even harder to wake up in the morning.   Like a nocturnal creature, melatonin loves darkness, and becomes engaged and effusive during the night, while exposure to light weakens it.  If there’s one characteristic of the modern world, it’s chronic exposure to light, and since most of us watch TV or use our computers late at night, this means that most of us are experiencing a considerably diminished production of melatonin.  No wonder we can’t sleep.

Chronic tiredness isn’t just a psychological problem, it’s also a physical one.  Sleep deprivation is associated with higher rates of obesity, diabetes, and depression.  It makes us less productive during working hours, and also more prone to dangerous accidents.

However, a new study published in the journal Current Biology provides hope.  Researchers in the study divided subjects into two groups and then monitored their melatonin levels.  One group of people slept outside in tents for a week, and the others remained indoors.   After camping out of doors all week, natural melatonin production shifted and began to rise in the outdoor sleepers.  Compared with those who continued to sleep indoors, the outdoor sleepers also went to sleep earlier and woke up earlier, and slept an average of two or more hours longer.   In another, earlier study, outdoor sleepers were able to increase their melatonin production and shift their sleep cycle by more then one hour after just one weekend spent sleeping outdoors.

These studies demonstrate the importance of light exposure for proper sleep, and reveal why sleep experts recommend dimming all lights, and removing all electronic screens from the bedroom at least an hour before going to bed.  If you continue to struggle with sleep even after carefully dimming or removing all light sources, a weekend camping trip is another good option.  As these new studies show, the enriching blue, natural light of morning has a powerful influence on our internal clock, and can quickly recalibrate the body’s natural circadian rhythm.   Why not take a trip now, while the scenery is so delicious, and the temperature is still warm?

Anti-Bacterial Bounty Found in Tasmanian Devil Milk

devil

My father-in-law was admitted to the hospital in the spring of 2014.  He almost died there.   For the previous week or so, he had been complaining of severe back pain, but laboratory tests done at the hospital revealed the true cause of his pain: sepsis, a staph infection that had taken hold in his blood.

The next few months were extremely difficult for all of us.  At first, we weren’t sure if he would survive at all.  Then, we weren’t sure if he would ever regain his strength, considering his age, which was 75.  He required a daily intravenous injection of antibiotics to kill off the bacteria, which drained him considerably.  Although the situation was bad, it could certainly have been worse:  he could have contracted an MRSA, or Methicillin Resistant Staphylococcus Aureus infection, in which case his death would have been certain.

Statistics now show that 23,000 people in the US die of these antibiotic-resistant infections each year.   A recent report from the Review on Antimicrobial Resistance warned that superbugs could kill one person every three seconds across the world by the year 2050, unless new, more effective antibiotics are found.

Enter our unlikely new saviour, the Tasmanian devil.  Researchers in Sydney, Australia have found six peptides in Tasmanian devil milk, and one of them has shown a particularly high effectiveness in killing the superbug MRSA.   Early tests show it can also kill Vancomycin-resistant enterococcus, another resistant bug, as well as fungi, called Candida, which are commonly involved in skin infections.

Considering the success of the peptides in Tasmanian devil milk, researchers will now explore the milk of other marsupial animals to see if more good news can be found.

Marsupials are the group of animals which carry their newborn babies in skin pouches.  The babies are small and under-developed, and the pouches are filled with bacteria.  Scientists suspect that without these extra bacteria-fighting peptides in their mother’s milk and in the skin of their mother’s pouches, most baby marsupials wouldn’t survive, which makes them potentially rich sources for other anti-bacterial peptides.

Although tests are still underway, scientists are hoping that this discovery could lead to new antibiotics in the next few years.  In the meantime, the natural antibiotic effects of many herbs may provide some help as we struggle to keep infectious bacteria at bay.  Though not as powerful as antibiotic drugs, they are less damaging to our liver and kidneys, and can therefore be taken for longer periods of time to stamp out infections before they have a chance to take hold.

Most of the herbs in our liver/gallbladder tinctures and in our Chrysanthemum tincture have anti-bacterial actions that can help to nip infections in the bud and prevent colds and flus from spreading.   They may not be as effective in killing MRSAs as Tasmanian devil milk, but they’re the best we’ve got for now.

Prevent Depression and Save Your Brain

stress

“The greatest weapon against stress is our ability to choose one thought over another.” –William James, American philosopher and psychologist.

Feelings of depression have become increasingly common in the modern world.   According to the WHO, 350 million people now suffer from depression worldwide, and in the US alone, 16 million adults had at least one depressive episode in the year 2012.  These numbers are quite different from what they were just a generation ago.  According to recent data collected from 6.9 million adolescents and adults, North Americans are struggling with more symptoms of depression, such as difficulty sleeping and eating, than their counterparts did in the 1980s.

The increasing prevalence of depression among adolescents has been even more alarming.  In a study of national trends published last November in the journal Pediatrics, teens were 37% more likely to have suffered from a major depressive episode compared to a decade ago.  In California’s largest school district, more than 5,000 incidents of suicidal behaviour were tallied last year, compared with only 255 during the year 2010-11.

In a paper written for the Proceedings of the National Academy of Sciences, scientist Robert Sapolsky wrote, “humans have dragged a body with a long hominid history into an overfed, malnourished, sedentary, sunlight-deficient, sleep-deprived, competitive, inequitable, and socially-isolating environment with dire consequences [for our emotional health]”.

Despite the increasing prevalence of depression, we still don’t quite understand how it’s caused, and the results of new research has been sobering.  It now appears that prolonged stress or trauma is strongly associated with decreased volume in the hippocampus,  the part of the human brain responsible for regulating thoughts and feelings, enhancing self-control, and creating new memories.  Unfortunately, the hippocampus also has the unique function of rapidly generating new connections between brain cells, so when the hippocampus shrinks, your brain shrinks too.

Under prolonged stress, your brain becomes flooded with high levels of glucocorticoids, such as cortisol, which we now know can disrupt normal information processing so that higher-order reasoning and decision-making becomes more difficult and fragmented.  As a result, positive or compassionate interpretations of events become more difficult to envision, and thinking becomes stuck in a negative groove of self-criticism and pessimism.

So, how can we prevent these increasingly common depressive episodes?  How can we protect our brains from the shrinking effects of excess cortisol?

Well, there are three things that have been proven to help:

1)  Take an omega-3 supplement.  Omega-3 fatty acids contain DHA or docosahexaenoic acid, which is a central building block of brain tissue.  DHA has natural anti-inflammatory properties that help to combat the effects of cortisol and prevent plaque build-up, which should promote the formation of more dendrites.

2) Exercise every day.  Increased blood circulation to the brain through daily exercise can  strengthen brain cells and neuronal connections.  Researchers suspect this is why daily physical exercise  has been shown to reduce the chance of developing dementia as you age.

3)  Practice daily prayer, meditation, or yoga.   All of these daily rituals strengthen what is called  “the relaxation response,” which lowers blood pressure, heart rate, and anxiety.  When your body is more relaxed, new studies show that gene expression becomes altered so that inflammation and cell death is less likely, and your body is better able to handle free radicals.  In the case of meditation, daily practice has been shown to strengthen the pre-frontal cortex, which grants us greater distance and control over our thoughts.  When we have greater ability to choose the thoughts we dwell on, and which to let go, depressive thinking has less chance to take hold.

Unfortunately for us, there is very little we can do to avoid emotional traumas like unexpected job loss, chronic illness, or physical and emotional abuse.  However, by taking certain preventative measures, we can help our brain stay more resilient against these stresses.  A strong brain is a controlled brain.   When our brain functioning is strong, we can choose and direct our thoughts rather than allowing them to run off a cliff.   So far, this has been proven to be the best protection against depression and dementia.

Is There a Limit to the Human Life Span?

JeanneCalment

My great aunt celebrated her 95th birthday this year.  She’s doing so well!  She is still able to walk by herself, although she sometimes uses a walker when she feels tired.  She still has all her teeth.  Her main difficulty is her diminishing eyesight, so her daughters regularly come to read to her.  Although she lives in a nursing home, she is in a room of her own, so  she still has some independence.  With her health in such good condition, we all hope she’s able to live for many more years.

After all, not many people reach her age.  Some scientists think there could be more healthy, elderly people like her in another generation.  Others think people like her will remain rare.  There’s been a heated  debate among scientists on this very subject in recent years, one that you’ve probably been unaware of, and it’s hard to say who might be right.

Approximately one year ago, Jan Vijg, a molecular scientist at the Albert Einstein College of medicine in New York, declared a maximum limit to the human life span.  He capped life expectancy at the age of 115, declaring that there are certain biological limits that just can’t be overcome by technological or medical advances.   According to his predictions, humans won’t be able to live any longer than that.

This declaration incited a rather riotous debate, with other scientists like Maarten Peter Rozing, Nick Brown, and Siegfried Hekimi of universities in Copenhagen, Groningen, and Montreal all declaring that Vijg was reading the data incorrectly.   They don’t see a limit to the human lifespan, and cite the death of Frenchwoman Jeanne Calment at the ripe age of 122 as proof that the human life span is steadily increasing.

But Calment died in 1997, and no one has been able to top her for twenty years.  This could either be a sign that a plateau has been reached, and it’s simply not possible to live any longer, or,  it could merely be a temporary lull.  Who knows, really?   With such a small data set, almost any conclusion can be drawn, and most of the scientific debate is a mere quibbling over the definitiveness of Vijg’s statement, not his reasoning.

Like me, most people probably don’t care so much about the length of human life.  We would just like to be assured that the quality is good, not matter how long it lasts.  And I think we’ve learned enough in recent years to be reasonably assured that if we can follow enough of the preventative measures, we’ll experience fewer of the negative parts of aging.  After all, no one wants to spend their last years stuck in a hospital bed all plugged up with tubes and wires.

So, I once again wish a hearty “Happy Birthday!” to my great aunt and very much hope that she lives many years more – and in continued good health.  I wish the same to all of you!  We’ll keep fighting the good fight, and with any luck, maybe we can follow in the footsteps of Frenchwoman Jeanne Calmont, and break that age barrier of 115 years – in good health, of course.
