Sleep deprivation could lead to weight gain
A new study has linked sleep deprivation with several eating
deficiencies, which could lead to significant weight gain.
Researchers have recently presented their study at the American
Heart Association's Epidemiology and Prevention/Nutrition, Physical
Activity and Metabolism 2012 Scientific Sessions, revealing that
there are several causal links between poor sleep patterns and
According to the study, those who don't get enough sleep often eat
too much, and also don't burn as many additional calories, which
results in weight gain. This is based on a study of 17 normal,
healthy young men and women for eight nights. Half of the test
subjects slept for only two-thirds of the normal time, with the
other half acting as a control group, sleeping normally.
Virend Somers, M.D., Ph.D., study author and professor of medicine
and cardiovascular disease at the Mayo Clinic in Minnesota said:
"We tested whether lack of sleep altered the levels of the hormones
leptin and ghrelin, increased the amount of food people ate, and
affected energy burned through activity."
Leptin and ghrelin are commonly associated with appetite, and the
results showed that a lack of sleep could be linked with increased
levels in these hormones.
Additionally, the sleep-deprived group were found to consume a
further 549 calories each day on average. Andrew D. Calvin, M.D.,
M.P.H., co-investigator, cardiology fellow and assistant professor
of medicine at the Mayo Clinic concluded: "Sleep deprivation is a
growing problem, with 28 per cent of adults now reporting that they
get six or fewer hours of sleep per night.
"Larger studies of people in their home environments would help
confirm our findings."
There are several ways to ensure that you get a good night's
sleep, which usually fit into three categories: The bedroom,
routine and lifestyle. The bedroom should be made to be a
sleep-centric place, with a good mattress and personal comforts
that make the room a 'sleep place'.
Getting into a regular routine before bed is also important. Go to
bed at the same time, wake up at the same time and try to nap less.
Finally, a healthy diet and good amounts of exercise will ensure
that your brain is properly ready for resting at night.
