Obesity Linked to Lack of Sleep
Women hoping to lose a few pounds should spend more time in bed, new research suggests.
A study published in the American Journal of Epidemiology has found that middle-aged women are much more likely to remain lean if they sleep well over a prolonged period. Those only catching a few hours sleep per night, by contrast, have an increased risk of putting on unwanted weight.
Researchers followed the progress of 68,000 women over a period of 16 years and the results add substance to previous conjecture that weight gain is linked to sleeping patterns.
Women averaging just five hours sleep per night were found to be 32 per cent more likely to have a 15 kilogram weight gain over the period than those sleeping for seven hours. Even an extra hour appears to play a part, with those sleeping for six hours 12 per cent more likely to put on this weight.
Similarly, the risk of developing obesity was increased by 15 per cent among those sleeping for five hours or less per night and by six per cent in those sleeping for six hours.
Significantly, sleeping for more than seven hours per night was not linked to an increased risk of developing obesity over this 16-year period.
The reasons for these results remain unclear, but experts have suggested that sleep deprivation may have the capacity to alter hormones that affect appetite and metabolism. There is also a chance that those sleeping badly eat more and enjoy less exercise as a result of their fatigue.
"Overall, our findings suggest that short-sleep duration is associated with a modest increase in future weight gain and incident obesity. These findings have the important implication that increasing sleep time among those sleeping less than seven hours per night may represent a novel approach to obesity prevention," the researchers said.
Obesity and Lack of Sleep
I would surmise that is definitely one of the culprits. I would also need to know what anti-depressants you are taking to judge how it impacts your sleep.
