Goodbye pajamas: 3 great reasons to sleep naked, according to science

Scientists agree: ditching your pajamas to sleep in the nude offers numerous health benefits.

It has been proven that sleeping without clothes at night improves sleep quality thanks to better body temperature regulation. This means less sweating and a lower body temperature. Furthermore, this habit promotes ventilation in intimate areas, limiting the growth of bacteria and fungi often caused by the heat and moisture trapped in synthetic fabrics, as noted by the media outlet Positivr.

On another level, sleeping naked enhances mental and relational well-being. According to an American study by Cotton USA, cited by Psychology Today, couples who habitually sleep naked report being happier. Direct skin-to-skin contact with a partner stimulates the release of oxytocin, the “bonding hormone.” This process helps reduce stress, eases insecurities, and increases desire. Conversely, according to a British study published in 2014, 48% of couples who sleep in pajamas say they are less fulfilled.

Finally, saying goodbye to your pajamas is good for the environment. This approach avoids the purchase of unnecessary sleepwear and reduces the amount of laundry, thereby saving water and electricity.
