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!
