Not only can sleep improve your cognitive (memory and brain connectivity) and immune system functions, but it can also be vital in helping muscles grow and losing weight!
A 2013 study found that sleeping between 6.5 to 8.5 hours a night is associated with a lower body fat percentage and a healthier body weight (Bailey et al 2013). And more importantly, consistent bed and wake up times were some of the driving factors.
This doesn’t mean that if you only sleep five hours a night you are unhealthy, it just means that sleeping more can be associated with a healthier weight, most likely due to the body resting and recouping during sleep!
