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.
