Turns out sleeping naked has a lot of health benefits, like these:
It's literally the coolest thing you can do. According to the Los Angeles Sleep Study Institute, one reason people wake up during the night and can’t fall back to sleep is because they’re overheated. Skipping jammies can help your body maintain a cooler temperature, which means you're less likely to wake up at 2 a.m.
It's good for wannabe dads. A 2015 study found men hoping to start a family or add to theirs shouldn’t just wear roomy boxers, they should sleep naked, too, to improve sperm quality.
