For many Australians, slipping into a cosy pair of pyjamas is as much a part of the nightly routine as brushing your teeth or turning off the lights. But what if we told you that your favourite flannelette set could do you more harm than good?
Recent research and expert opinions challenge the long-held belief that pyjamas are essential for a good night’s sleep.
There’s growing evidence that sleeping in the nude could offer a surprising range of health benefits. Let’s take a closer look at why ditching your pyjamas might be the best thing you do for your sleep, your skin, and your overall well-being.
Our bodies are governed by a 24-hour internal clock known as the circadian rhythm. This rhythm controls everything from when we feel sleepy to when we feel alert, and it’s heavily influenced by light and temperature.
Our core body temperature naturally drops by about one to two degrees Celsius as we prepare for sleep. This cooling process helps signal our brain that it’s time to rest.
Wearing pyjamas—especially those made from synthetic or heavy fabrics—can trap heat and interfere with this natural cooling.
If your body can’t cool down efficiently, you may find it harder to fall, stay, or reach the deep, restorative sleep stages that are so important for health as we age.
A cooler sleeping environment has been linked to improved sleep quality. Some studies suggest that people who sleep naked fall asleep faster and experience fewer nighttime awakenings.
For those who struggle with hot flushes or night sweats (a common complaint during menopause and andropause), sleeping without restrictive clothing can be especially beneficial.
Our skin is our largest organ, and it needs to breathe, especially at night, when it’s busy repairing itself.
Tight or synthetic pyjamas can trap sweat and bacteria against the skin, leading to irritation, rashes, or even fungal infections. This is particularly relevant for older adults, whose skin can become thinner and more sensitive with age.
Sleeping in the nude allows air to circulate freely, reducing the risk of breakouts and promoting healthier, clearer skin.
If you choose to go au naturel, ensure your sheets are made from natural, breathable fibres like cotton or bamboo, and wash them regularly to keep things fresh and hygienic.
Here’s another surprising benefit: sleeping in a cooler environment (or without clothes) may help with weight management.
Research from the United States National Institutes of Health found that people who slept in cooler rooms had higher levels of brown fat, a type of fat that burns calories to generate heat.
Over time, this could help support a healthy metabolism and reduce the risk of weight gain, which tends to creep up as we age.
The benefits don’t stop there. Improved sleep quality ripples throughout the body, supporting everything from immune function to mental health.
Some studies have linked better sleep (and by extension, sleeping naked) to:
- Lower risk of type 2 diabetes
- Reduced risk of heart disease
- Improved mood and reduced risk of depression
- Sharper focus and memory
- Increased productivity during the day
For couples, sleeping naked can also foster greater intimacy and connection. Skin-to-skin contact releases oxytocin, the ‘love hormone’, which can help reduce stress and promote feelings of closeness.
Feeling comfortable and unrestricted can boost your confidence and self-esteem even if you’re not sharing a bed.
