Clothes vs. No Clothes while sleeping, that is the question? I recently did a little research to find out if there was really a health benefit for sleeping in the buff. I was pleasantly surprised to find there are multiple reasons to forget your jammies when climbing into bed tonight! According to, Intelligence For Life, on YouTube one reason a person should sleep naked is because it can boost your metabolism causing your body to burn "brown fat" which is the good fat we want to burn helping to aid in fat loss. Another reason is our bodies need to be cooler in order to reach a more restful sleep pattern.
