THE IMPORTANT OF SLEEP

Sleep Deprivation

"When we analyzed our data by splitting our subjects into 'short sleepers' and 'long sleepers, we found that short sleepers tended to have a higher BMI, 28.3 kg/m2, compared to long sleepers, who had an average BMI of 24.5. Short sleepers also had lower sleep efficiency, experienced as greater difficulty getting to sleep and staying asleep," said lead investigator

Arn Eliasson, M.D.

The force of sleep

It has also been established that if we do not sleep enough, our neuroendocrine control of appetite can become disturbed, leading to overeating, this may altered insulin resistance, and a higher risk of developing Diabetes Type 2 - all of which make a person put on weight.  Several studies have shown that sleep deprivation damages the body's ability to regulate eating by lowering levels of leptin, the hormone that tells the body when it has had enough. Scientists involved in the Integrative Cardiac Health Project at Walter Reed Army Medical Center found a consistent link between body mass index (BMI) and length and quality of sleep.

Researchers from the University of Bristol, England, found that if a child is not getting enough sleep he/she is at higher risk of becoming obese. They also believe that lack of sleep may alter hormones so that children end up consuming more food, as well as the wrong types of food.

Not only will you risk putting on weight for hormonal reasons caused by sleep deprivation, but you are also less likely to want to exercise. Several studies have found that people who do not sleep enough are less likely to keep up with any exercise program because they are tired.
