Some experts are of the opinion that being bare-skinned helps your body cool down and work in conjunction with your circadian clock to induce sleep. A 2012 study published in the Journal of Physiological Anthropology looked at how thermal environment could influence sleep and found that cold exposure was linked with positive benefits in semi-nude subjects. In contrast, slow wave sleep and rapid eye movement (REM) sleep — both considered deep stages of sleep — reduced with heat exposure, according to the research. However, there is a need for more specific and conclusive scientific study on the subject.
In my case, the first night’s lack of success only fueled me to try the hack for a few more nights that week. While I did get more comfortable with not having clothes on while sleeping, I didn’t see a big difference in how quickly sleeping naked took me off to dreamland. Perhaps, this tip is best for someone who is prone to hot flashes or night sweats, like women experiencing menopause, as recommended by board-certified OB/GYN Dr. Jodie Horton (via Well+Good). If you find yourself waking up at night to turn on the AC or if pushing your blanket off of your body to get cool has become a regular exercise to get comfortable, you could try sleeping in the nude. Maybe it’ll help you fall asleep faster and even stay asleep for longer.
