Almost 40% of us wear pajamas to bed, and there’s nothing cozier than your favorite winter PJs. But what we choose to wear to bed can actually affect our sleep, our looks, and even our health. If your fluffy jammies cause you to overheat at night, it may be one of the reasons you’re not drifting off as easily and end up waking up feeling tired in the morning.

We at Bright Side also love to throw on our comfy pajamas and hide under a warm blanket when it’s chilly outside. So we decided to find out why warm PJs may not be the best choice of sleepwear.

If you’re too hot in bed, your core temperature won’t be able to fall, keeping you from getting a good night’s sleep. Having a lower temperature at night helps your body to recover better and can even boost your metabolism. If you’re looking to wear something other than cotton pajamas, silk might be a good choice. It’s a natural thermal regulator and can keep you warm on cold winter nights thanks to the heat that is kept between the silk threads, creating an isolation effect.

What’s your favorite type of nightwear? Do you prefer to sleep in warm or light pajamas?
