Sleep is related to people's physical as well as mental health, and lack of it can cause cardiovascular illnesses that could be fatal.
A recent study in the Journal of the American Medical Association suggests that sleep disorders are directly linked to obesity.
Scripps Research in California asked 120,000 participants to wear electronic sensors to gauge their sleeping patterns every day for two years. Using that wealth of data, Scripps Research compared the relationship between sleep and body fat levels.
Contrary to the intuitive sense that fat people must sleep more, the study showed the opposite. The average person sleeps six hours and 47 minutes a night, and the longer they sleep the lower their body fat.
Obese people tended to sleep six hours and 37 minutes on average, but slim people slept six hours and 52 minutes. Also, obese people slept more fitfully.
A lack of sleep leads to longer hours awake and thus more time to eat. But sleep also affects the secretion of hormones in the body, and less sleep could mean a lower metabolic rate.
To lose weight, proper diet and exercise are essential, but so are regular bedtimes.
