Can Too Much Light at Night Be Deadly?

by Theanna Zika on March 15, 2011

At first glance the sentence above seems preposterous.  However, with a bit of explaining, it will make more sense.  Personally, I feel this is a huge breakthrough for explaining many things, including the rising rates of obesity, depression, diabetes, and breast cancer in the Western world.

When we were evolving, we experienced about 12-14 hours of darkness every 24 hours. We did not have lights or TV’s or computers to occupy our time at night.  In the modern world, this is exactly what is going on.   Most of us spend our night time hours surrounded by light.  Our homes are lit up with TV’s, computers, cell phones and other gadgets.   City lights from outside our homes also reach our eyes.   What is the effect of all this “unnatural” light at night on our bodies?

According to doctors and researchers, all this light interferes with our body’s natural rhythms (called circadian rhythms).    Enter melatonin.    Melatonin is an important hormone that has been proven to be protective against cancer.   Our pineal gland produces melatonin, but only when it is dark.   Completely dark. Light will stop the production of melatonin – even a little bit of light.  The reason this is so important is because melatonin is what makes us sleepy.  It enables us to sleep soundly and deeply.  The way it should theoretically work is when the sun sets, the body begins to produce the melatonin.   After an hour or so we begin to become sleepy and eventually fall asleep at a decent hour – say 9pm.   We would sleep soundly and only be awakened by the sun coming up.

But what is happening in present day society is far different.   Many of us actually ratchet up the light around us as night falls.  At this point I need to explain I am speaking about a particular light called blue light.  Blue light is picked up readily by a photoreceptor in our eye that has nothing to do with vision.  Blue light penetrates this photoreceptor more than green or red lights.  Thus, blue light is very powerful at regulating melatonin and our circadian rhythms.

This blue light is emitted from our computers, TV’s, light bulbs, iPads and other gadgets.  Researchers are warning us that as we stare into these things at night, our melatonin is suppressed and our bodily rhythms are disrupted.  Our bodies are confused as to whether it is day or night.  Which hormones to secrete or shut down?   This creates havoc in the body and been directly related to insomnia, depression, obesity, cardiovascular disease and of course cancer.  Because blue light at night can disrupt our hormones, studies are showing that breast cancer in particular, to be related. In primitive countries where they do not have all this blue light at night, the incidence of breast cancer is much less.  And as countries “westernize” their rates of breast cancer increase.

When researchers want to study the effect of disrupted body rhythms and melatonin, they look at shift workers.  Shift workers, such as nurses, have been shown to have higher incidences of many health problems including depression, diabetes, cardiovascular disease and breast cancer.   A study by Dr. Eva Schernhammer, an epidemiologist at Harvard, found nurses who have worked the night shift for 15-30 years had higher risks of breast and colon cancer.  “People who work at night will always have lower levels of melatonin than the normal population (who are not exposed to light all night)”.

In fact, the World Health Organization in 2007 classified shift work as a risk factor for breast cancer.  And in 2009, the Danish government began compensating female shift workers who have breast cancer.

So now that we are aware of the implications of blue light at night, what are some of the things we can do to protect ourselves?

  • Use full spectrum bulbs in your house and office during the day.  Because remember this VERY important point: blue light is not dangerous! It just signals your body to be awake.  You want to have that during the day but not at night where it disrupts your body’s rhythms.  (In fact, studies show we are not having enough bright light around us during the day when we need it and too much at night when we don’t.)
  • Turn off computers and electronic gadgets once the sun sets, and avoid watching TV late at night.   You especially do NOT want to fall asleep in front of the TV all night long!  Some remotes have timers on them so you can program the TV to turn off by a certain time.
  • Use “low blue lights” in areas where you spend most of your time in late evening, such as your living room, bedroom and bathroom.
  • If you have to get up to go to the bathroom in the night, make sure your path is clear and resist turning on the light for even a few moments.  That short of time is enough to stop all melatonin production and disrupt things.
  • Sleep in TOTAL darkness.  This means no night lights, no clock radio or cell phone glowing on the bedside table and use blackout shades and drapes if ANY light from outside is coming through your window.   Many experts say you should not be able to see your hand in front of your face.
  • Sleep when it is dark outside and get up when the sun comes up.  At the very least try and be asleep by 10pm and be up by 6 am.
  • Avoid working the night shift.  This one cannot be stressed enough.  Experts strongly suggest you trying to switch your hours if you are currently working at night.  At the very least try not to keep the shift longer than a month or two to give your body time to readjust in between.  Perhaps give your supervisor this article to read!
  • If you have to do shift work, when you come home to sleep, make your bedroom as dark as possible by using black out shades.  Use all the tips above to simulate night so you will produce melatonin.  Also try wearing eye pads to shut out the last bit of light.

Constipation Consternation

by Theanna Zika on March 15, 2011

Remember that constipation itself is not a disease, but a symptom that something within the system is not quite right.  Here are some guidelines to help you decide if you truly are constipated:

  1. You seem to have difficulty passing stools, or it seems to take forever
  2. The stools are hard or lumpy
  3. You feel blocked up, like you can not empty your bowel completely
  4. You have fewer than 3 bowel movements a week

Why do we get constipated?  There are many different reasons — poor diet, lack of exercise, and overuse of laxatives are the most common offenders.  Other factors include medical conditions, certain medications, and consciously holding back bowel movements.

A poor diet is one of the leading causes of constipation.  Lack of fresh fruits, vegetables, and whole grains in the diet is a prime cause.  Research increasingly shows that regularly eating these foods can help prevent constipation.  Too much fat, sweets, dairy products and eggs also can be a problem, and is not a healthy way to eat.  So is the consumption of prepared foods on a regular basis.

A lot of seniors live alone, and just don’t enjoy cooking for one or eating alone.  It’s easy to adopt a constant diet of instant meals, already prepared. The problem is that too often these meals are lacking in fiber, as well as other vital nutrients, and contain way too much salt and fat.  Folks who have problems with their teeth will often choose foods that are soft and overly processed, containing small amounts of fiber, if any.

Not drinking enough liquids is also a leading cause of constipation.  We cannot stress enough the importance of adequate fluid intake.   Water is always the cheapest and the best, but any liquid counts — juice, milk, coffee, tea, soup.  In fact, so many people enjoy a good bowl of soup at mealtime, why not add plenty of vegetables and broth, and get some of your daily liquids this delicious way?  Just watch out for the salt.  If you buy canned or packaged soup,  ALWAYS CHECK THE LABEL FOR SODIUM CONTENT!   Please do try the many varieties of low-sodium soups available now.   Why not spend some time cooking up a batch of your own?  If that seems a bit overwhelming, perhaps you could enlist the help of a friend, neighbor, or family member to give you a hand.  Many seniors have treasured, time-tested soup recipes that have been passed down through the years. Soup freezes well, and can be put into smaller containers ready to take out and heat when needed.   Nothing beats the taste of home-made soup in my book, and eating a bowl often brings back happy memories of a pleasant day spent in the kitchen, chopping, blending, and stirring, as well as thoughts of that special person who first made it for you.

Overuse and dependence on laxatives and enemas can only spell trouble for your bowels. Rather than being a cure for constipation, their frequent use will cause your bowels to “forget” they can work on their own.   Eventually this will lead to your body no longer having any natural bowel movements.   Frequent diarrhea is usually the end result, with resultant loss of even more liquid from the body, not to mention the discomfort, unsanitary conditions, and difficult clean-up that diarrhea brings.

We’ve all been lectured to the nth degree about the importance of exercise, but it is so very true, especially in regulating bowel movements.  Too much sitting around by couch potato types makes for too little bowel activity!   If you’ve been ill or otherwise confined to bed, you will probably suffer from constipation until you’re back on your feet and moving around.  Keeping active, even if it’s just walking around the house or yard is always the best bet.

Try not to hold in your bowels on a regular basis — if you wait too long to go, or practice this on a regular basis, it may result in constipation.  Most of us prefer to use our own bathroom at home.  Make a visit to the bathroom before going out.  Perhaps you can schedule your excursions well before or after a visit to the bathroom is expected.

There are certain serious medical conditions that can lead to constipation.  Among them are stroke, diabetes, intestinal blockage, and irritable bowel syndrome.  These conditions can cause a malfunction in the nerves and muscles that your body uses for moving the bowels.   Speaking with your doctor about this is a good first step in determining if this is a problem for you.

Quite a number of commonly used medications may cause constipation. Antidepressants, antihistamines, antacids containing aluminium or calcium, and medicines to treat high blood pressure and Parkinson’s disease are often offenders.  Speak with your doctor if this seems to be the case.

Let’s put a positive spin on all this and discuss what we can do to help keep constipation at bay as much as possible.  As we mentioned, first rule out that a medical condition or medicine is the root cause by speaking to your doctor.  If that is not the case, here are some time-tested ways to help get things moving again.

The number one remedy is to simply add some fiber to your diet!  Try fresh fruit or vegetables, whatever kind you like.  Bear in mind that corn and potatoes should not be your first choice — they’re not particularly helpful.  Dried fruits such as prunes, figs, apricots and dates are tasty and full of fiber.  They make a wonderful sweet dessert or snack.   Small doses will work fine — dried fruits are concentrated sources of fiber.  Be aware that you can get too much of a good thing!

Try incorporating some whole grains into your diet.  Eating oatmeal (rolled oats, not the instant kind in a little envelope) is a great way to start your day, especially with some fruit on top!  Make your toast and sandwiches with whole grain breads or English muffins. Brown rice is better than white rice.   Eat your potato baked, with the skin on — try a sweet potato rather than your usual russet, and you’ll get a leg up on healthy beta-carotene, so necessary for healthy vision and immune system.  Have you tried barley in your soup instead of noodles, rice or potatoes?

Take some beans, please! They’re inexpensive, loaded with fiber, easy to keep and store. You should always have a can or two in your pantry.  Try them in a salad instead of croutons (you are eating fresh salad greens, aren’t you?) or in chili (make it with ground turkey instead of beef to reduce artery-clogging fat).  Need a quick, healthy, fiber-rich snack?  Scoop up a small handful of nuts (unsalted if you please) or pop some corn — both have plenty of fiber.  Once you get on the bandwagon of fiber-rich foods, you’ll find there are many more you like than you realized — they’re everywhere you look!

Yes, you can use fiber-rich additives — the kind you mix with a glass of water.  But nothing beats eating healthful, fiber-rich foods at every meal.  It’s easy to get in the habit once you educate yourself and become aware of the nutrition value in what you eat every day.

Don’t forget to drink enough liquids to keep yourself hydrated.  As we age, our tastebuds and thirst indicator don’t function as effectively.  Don’t rely on feeling thirsty — you may not be.  Drink something at regular intervals during the day to keep yourself properly hydrated, and this will also help regulate your bowels.  And do keep as active as you can. Couch potatoes do not have healthy elimination, especially as they age.  Walk around the house or the block, go out and get your mail, do some yardwork if you’re up to it physically.

If you follow these tips and still have problems, talk to your doctor.  Perhaps there is an underlying condition that you’re unaware of.   But take heart, this is not rocket science! Some simple changes in diet and exercise may be just what you need to feel better, and they’re all simple steps you can take on your own.  Give it a try — what have you got to lose but that awful constipation?
