Sleep loss increases the risk of obesity...

It may sound crazy.. but lack of sleep can lead to putting on weight..
1) Poor sleep is strongly linked to weight gain. 
Tests have shown that 55% of adults with lack of sleep are more likely to become overweight. 

2) Better sleep, less calories
Studies show that the less we sleep the higher the appetite hormone ghrelin tends to be, whereas the hormone leptin that suppresses appetite is reduced. 

3) More sleep, more productivity
Lack of sleep can lead to lack of concentration and impair brain function. Get that 8 hours a night! 

4) Reduce the risk of heart disease
Getting less than 7-8 hours of sleep per night can greatly increase your risk of heart disease and stroke. 

5) Cut the diabetes risk
Sleep deprivation can cause pre-diabetes in healthy adults. 

6) Feel better! 
Lack of sleep is also linked with mental health issues such as depression.
