Sleeping naked also helps to regulate your cortisol levels.
Cortisol does several things in your body, some beneficial, and some not as much.
One thing it does is suppress immune response.
Cortisol is also called the stress hormone.
An overabundance of cortisol leads to weight gain, anxiety and cravings for junk foods.
Sleeping naked reduces your cortisol production.
So you wake up feeling less anxious, and ready to face your day!
