Many things can affect your metabolism, one being your sleep patterns. Sleep not only allows your brain to reset, but it also affects the way your body processes the food you eat and hormone levels. Short sleep has shown a link to a high risk of obesity as well as a link to diabetes and other metabolic diseases. As you sleep your body uses the energy stored to process the fatty tissue in your body. The shorter the sleep, the shorter amount of time your body is able to regulate the fatty tissue therefore affecting your metabolism.
The optimum amount of sleep has been shown to be around 8 hours. Anything less than 7 hours has shown a correlation with metabolic issues as well as anything more than 8 hours can affect weight gain. Getting the right amount of sleep matters!
