Getting eight hours sleep a night key to staying slim
Getting eight hours sleep a night is the key to staying slim, scientists have claimed.
New research has showed that people who slept for less than six hours a night, or more than nine, put on more weight than those who managed seven or eight hours every night.
Scientists found that people who didn’t sleep for long enough gained nearly 4.4lbs (2kg) compared to those who slept for the suggested number of hours.
Those who slept for too long found their weight increase by 3.4lb (1.58kg) more than those who had the recommended number of hours over a six year period.
People who were asleep for less time were 27% more likely to become obese.
Scientists explained the results saying the amount of sleep a person has affects their hormone levels – especially hormones which control appetite and feeling full after a meal.
Lead researcher, Jean-Philippe Chaput said: ‘Our study provides evidence that both short and long sleeping times predict an increased risk of future body weight and fat gain in adults.’
He added: ‘Since preventing obesity is important, a pragmatic approach adding sleep hygiene advice to encouragement towards a healthy diet and physical activity may help manage the obesity epidemic.’
Both UK and American sleep experts explained that one way of getting a good night’s sleep is by going to bed and getting up at the same time every day even at weekends. Having a relaxing routine prior to your bedtime, like taking a bath or reading, is also beneficial.
