Did you know that getting enough sleep helps you maintain your weight? According to Prevention,

People who logged 7 to 9 hours a night had an average BMI of 24.8 –  almost 2 points lower than the average BMI of those who slept less, University of Washington researchers found. Too little sleep may throw off hormones that regulate appetite.

Lack of sleep can also mess up critical balances of hormones that control anabolism and catabolism.

Did you know that regularly getting inadequate sleep can lead to more battles with the cold bug? According to Prevention magazine,

People who get less than 7 hours per night are 3 times likelier to catch colds, according to a JAMA study. Reason: Sleep boosts immunity; too little impairs it.

So next time you think 6 hours of sleep is enough, think again. Your sniffles might just go away!
