Evidence suggests that, yes, ditching your sleepwear may in fact have a number of benefits, including better sleep. Interestingly enough, a mere 8 percent of Americans admit to sleeping naked.1 Many of these health benefits result from the fact that sleeping naked helps prevent overheating, which can have a significant impact on your sleep quality. As you fall asleep, your body temperature drops, and this drop in core temperature actually helps you sleep better. As you wake, your body temperature rises, which is why it's much more difficult to fall asleep and stay asleep when you're hot. Many keep their homes too warm to begin with, and wearing pajamas to bed will make you even warmer, which can lead to restless sleep and frequent waking. Ideally, keep the temperature in your bedroom below 70 degrees F.
