As the bitter winter nights draw in, a sleep expert says swapping your pyjamas for your birthday suit is the best way to get some shut-eye – and surprising health benefits.
According to Sammy Margo, a chartered physiotherapist who specialises in sleep, going to bed starkers can have a marked effect on the quality of your slumber.
“Your body temperature plays a crucial role in the timing of your sleep,” she told Metro.
“It’s linked to your circadian rhythm — the internal body clock which controls your sleep-wake cycle.
“Falling into a deep sleep is linked to cooling your body, so allowing your body to cool down by sleeping naked can signal to you that it’s time to sleep.”

Sleeping naked in the colder months could also be beneficial for those looking to heat things up between the sheets, as it leads to “increased physical and emotional intimacy”, she added.
This occurs due to skin-on-skin contact raising the body’s production of the hormone oxytocin, which is linked to feelings of love and bonding.
Studies suggest turning in undressed brings all manner of health benefits.
As well as helping people to regulate their circadian rhythm while maintaining the most healthy body temperature, it can also give you healthier skin by helping you get a better quality of sleep, according to Healthline.
Other benefits are thought to include reduced anxiety and stress, improved vaginal health, weight gain prevention, a decreased risk of heart disease and type 2 diabetes, a boost to male fertility, and even increased self-esteem.
Another expert recommends a simple five-minute health hack to balance out your circadian rhythm and optimise your sleep.
Podcaster and author Liz Moody told Parade: “A circ walk is short for a circadian rhythm walk, and it’s a quick walk outside as close to when you wake up and the sun comes as possible to set your circadian rhythm.”
She added: “This tells your internal clock what time it is, and your internal clock regulates much more than just your energy levels and sleep.”
