If you're sleeping with your partner, the skin to skin contact can increase the release of oxytocin - the love hormone. Oxytocin plays a huge role in sexual responsiveness and achieving orgasm, and it also helps reduce stress and even combat depression. Plus, many men are highly sensitive to visual stimuli, so when your SO sees you naked in bed, even if you're not touching, he'll already get into a more, let's say, joyful mood.

A study published by the American Academy of Sleep Science states that your body temperature naturally lowers when you sleep deeply. Sleeping in your PJs can hinder this natural decline in temperature, thus disrupting your sleep cycle and even potentially causing insomnia.

We've established that going to bed naked helps you rest better, which, in turn, helps keep your cortisol levels under control. At night, when you sleep, your production of stress hormone considerably decreases, only to rise again in the morning, to get you energized and ready to get up and start the day. If you don't get enough rest at night, you will wake up with unnaturally high cortisol levels, which will trigger your appetite for comfort food and make you overeat. Thus, if you wish to prevent belly fat, you may want to start sleeping naked!

Sleeping naked airs out the skin all over your body, allowing it to breathe. This can prevent rashes and skin diseases, which often develop due to moist, restricted skin.

Without that T-shirt getting all twisted when you sleep and that annoying elastic band strangling your waist, your blood will be able to flow more freely through your body. The improved circulation will benefit your heart, arteries, and muscles, as the oxygen-rich blood will be able to stroll freely to your extremities.

A 2014 study published by NCBI found that feeling colder during sleep can improve your metabolism, decrease blood sugar levels and prevent type 2 diabetes. The authors discovered that, when the subjects slept almost entirely naked, their health improved within only a few weeks, and their unhealthy fat started to disappear as well.

The vagina is naturally a humid and warm place, creating the perfect corner of heaven for bacteria and yeast to flourish. By getting rid of your pajamas and allowing your lady garden to breathe, you reduce the probability of developing fungal infections and prevent bacteria from overwhelming the normal vaginal flora.

So, what do you say, girls? Will you say bye-bye to your PJs tonight? Can you think of other benefits of sleeping in the nude?
