4. Reduced Body Temperature Activates Fat
You are cooler with no clothes on, and sleep actually drops your body temperature. Cooler temps are relaxing, and they activate your brown fat to burn more calories by speeding up your metabolism. It also reduces the cortisol hormone, which helps you lose weight.
3. May Improve Your Sex Life
Sleeping naked can improve your sex life if you sleep with a partner. The free feeling does have benefits. Skin to skin contact increases the hormone oxytocin, which decreases stress, builds better relationships, and improves general well-being.
2. Saves Money
No pajamas to buy, although you may have to wash your sheets more often depending on how often you enjoy sex.
