I was wondering how many hours of sleep you get (on an average) each night. I sleep about 6 hours each night. It is said that sleep could have more effect on your health than you think . Here is the article I quoted from Reader's Digest, November 2007 issue :
It could make you thinner.
The less sleep you get, the higher your body mass index tends to be. Research showed that people who sleep five hours a night were found to have 15 per cent more ghrelin (a hormone that boosts hunger) in their bodies and 15 per cent less leptin (which suppresses it) than those sleeping eight hours.
It could boost your memory.
Sleep plays a key role in making new memories stick in the brain. A Harvard experiment showed that subjects taught complex finger movements such as a piano scale recalled them better after 12 hours’ sleep than 12 hours’ wakefulness.
It can fight colds, ulcers and even cancer.
Good sleep boosts the immune system. Melatonin, produced when you sleep, is a cancer-fighting antioxidant. Night-shift workers may have up to 70 times greatest risk of breast cancer. Also, the chemical to repair damage to the stomach lining is secreted during sleep, so staying up all night regularly could raise your risk of ulcer.
It can slow down ageing.
Persistent sleep debt affects carbohydrate metabolism and hormone function in a way that may increase the severity of age-related chronic disorders. A large-scale study concluded that people who sleep six to seven hours a night live longer than those sleeping less than 4-5 hours.
So how many hours do you sleep?
