circadian rhythm

Is technology making us fat?

There was a time when TV was blamed for the obesity epidemic. Then focus switched to sugar containing foods. Now that we have reduced the amount of TV watching and are more aware of the effects of high sugar foods, we as a nation continue to struggle with weight gain.

In reality, its not just about being a couch potato or making poor food choices. We have badly neglected another major change in how we spend our lives and how it affects us: We are exposed every day to multiple artificial sources of light close to our faces. There is in addition an excitement and "buzz" generated by the interactive nature of social media that draws us in and keeps us glued to these sources of light.

Let me explain:

The human body has two timing devices built in. One is a timer that counts the duration of wakefulness. The longer you have been awake the sleepier you will get. The other is a 25 hour clock that needs to be adjusted every day in order to stay on time. It allows for adjustments with shortening and lengthening of days.

The clock's proper adjustment relies on various signals, the most important of which is the presence or absence of light. The presence of light as it passes through the eyes, via a nerve circuit to the brain tells the mind to be awake and alert. The absence of light leads to the production of melatonin in the brain which reminds the body and mind that it is time to rest.

With all the light sources that we expose ourselves to, we hardly give our brains the opportunity to perceive the absence of light. It is like living in Alsaka or Norway in the summer, for all of us. This leads to a shortening of the sleep cycle and development of the effects of chronic lack of sufficient sleep.

Choose the best answer:

Chronic lack of sleep is a major cause of:

1. Food cravings.

2. Slowing of the metabolism.

3. Increased need to consume calories to stay awake and alert during the day.

4. Feeling exhausted, leading to decreased level of activity.

5. None of the above.

6. All of the above.

Yes you guessed it right. All of the above.

What if a whole nation of 300 million people sleeps on average an hour less than it did 20 years ago and 2 hours less than at the turn of the 20th century?

Sleep well. Sleep enough. Be rested and perform at your best!

On Sleep Cycle Problems Wrongly Termed Insomnia: What Can You Do?

Continuing from our previous discussion on how problems with the sleep cycle are wrongly termed insomnia, let's talk about what you can do to help yourself:

1. Recognize the problem:

Of course, you have to realize the nature of the sleep problem. "Delayed Sleep Phase" is the commonest disorder of sleep cycle. It commonly runs in families, and is very prevalent among teens, young adults, creative people and those with "active minds". Anxiety is often associated with delayed sleep phase, as well as a tendency to want to stay up at night, to accomplish tasks that are difficult to complete during the day. A frequent statement is that "my mind seems to wake up when it is time to sleep."

2. Do you really want to make it better?

Sounds like a silly question. But the point is that it is very difficult to make this problem better unless the person suffering from it is motivated to make it better. The good news is it can be completely better, without prescription medicines if you are willing to learn about how the body's sleep mechanisms work, how they get disturbed and how to return them to their natural function. Some people decide however that their tendency to be awake at night and asleep during the day works for them; musicians, performers and writers being some of them.

3. "Just tell me what to do?"

I will expand on the following next time but here are some of the things to do:

- Bright light exposure of 5,000 lux or more starting 30 minutes before your "natural" wake up time. (Usual indoor lighting is 100-200 lux).

- Do not take a daytime nap of over 30 minutes, and none in the last six hours before bedtime.

- Turn down the lighting one hour before intended sleep time. Turn off all sources of lighted electronic screens.

- Take melatonin 1.5 mg or less from a large reputable manufacturer, one hour before intended sleep time, BUT no earlier than ten hours of "natural" wake up time. No added ingredients are necessary.

- Eat a filling starchy snack 30 minutes before bed time; not fatty, not sugary food.

- Avoid all sugary or caffeinated drinks in the last six hours before intended bedtime.

Relax. You will reach your goal and you can do it. No one has invented any magic pill stronger than human will power.

More next time. Adios.

The Magic of Melatonin! (Requires a Magic Wand)

People looking for over the counter sleep aids often find melatonin along side other supplements. Since it is easily available, considered a supplement and not a medicine, there is plenty of incentive to at least try it. There are dozens of melatonin products on the market, freely available at supermarkets, pharmacies, health food stores and online. People take it in increasing doses (I have known people to take as much as 15 mg in one night), combine it with Benadryl products or alcohol, with various vitamins and in combination with various herbal preparations. It may make you briefly drowsy. It may seem to help you fall asleep for a few days. Unfortunately, that's about it. So what about the magic?

The magic wand you need to unleash the powerful magic of melatonin is to know the science behind what the substance is and how it works, and most importantly what it works for. Melatonin works fantastically well for people with "delayed sleep phase syndrome", a medical term describing the inability to fall asleep at a socially acceptable time and wake up at a socially acceptable time in order to be productive. It is a very common sleep problem often misdiagnosed as insomnia. It is more common in adolescents, and in creative people, musicians and artists; and often runs in families.

These people are fully capable of getting sufficient sleep but end up not getting enough because they don't get sleepy until later in the night and have to wake up early to go to school or work. If they could sleep in every day and work started later in the day they would be fine.

If melatonin is taken in the smallest amount available, it works best. Take more and you will likely be groggy when you wake up. It should be taken no earlier than 8 hours after naturally waking up, and about an hour before intended bed time. The product has to come from a reliable manufacturer since no one is effectively regulating the quality of the product.

Most of all, if you expose yourself to bright sources of light after taking melatonin you will cancel out its effects. These bright sources include all kinds of handheld and electronic device screens that emit light. Its effect will also be reduced if you activate your mind, get busy thinking, worrying or performing mental tasks.

Lots of caveats, true. But the potion's magic has the potential to change countless lives, provided it is used properly, with wisdom and knowledge. It is typically inexpensive and works much better than sleeping pills, for the person with "delayed sleep phase". For everyone else, unless your sleep physician specifically recommended it, you are probably wasting your money.
