Sleeping naked promotes intimacy among couples. Close contact with a significant other can massively boost the amount of oxytocin in your brain. This hormone is the neurotransmitter which helps you feel those impulsive good feelings to your other half
A study from the National Institute of Child Health and Development at Stanford University found that men who slept in the nude instead of wearing boxer shorts or briefs had a 25 percent lower rate of damaged DNA in their sperm than men who did wear them. Fertility may decrease as sperm gets overheated.
Sex is a great form of exercise and a stress reliever. If you and your partner regularly sleep naked next to each other, the likelihood is that you’ll have more sex than you would when wearing those restrictive PJs.
Often when you wake up from a night’s sleep in your preferred form of pajamas, you feel clammy and sticky from sweating during the night. Reserve the pajamas for those menstrual days.
