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. Studies show that the optimal room temperature for sleep is between 60 to 68 degrees.
One study showed a surface skin temperature difference of as little as 0.08 degrees F (or 0.4 degrees C) allowed subjects to sleep more soundly. But the benefits of sleeping in the buff don’t end there.
