sleeping without any clothes on has numerous advantages and benefits.
For a good night’s sleep
Sleep experts agree it is important to keep cool at night as your body temperature needs to drop by about half a degree for you to fall asleep. The brain, driven by your internal body clock, sends messages to the blood vessels to open up and release heat.
“Your core temperature is at its highest at 11:00p.m. and its lowest at 4:00a.m,“If anything prevents that decline in temperature, the brain will wake itself up to see what’s going on, meaning you’ll struggle to get to sleep or you’ll have disturbed sleep.
“The advantage of sleeping naked is it’s easier for the body to cool and maintain the lower temperature the brain wants to achieve,
Disrupted sleep from being too hot does not just mean you will get less sleep overall, but it might mean less deep sleep which is the most restorative type. Deep sleep is key for memory consolidation and the production of growth hormone — important for cell repair and growth.
Wearing nothing to bed can help women avoid developing yeast infections, such as thrush,
“Thrush loves warm, restricted environments. So, wear something loose or preferably nothing at all. “If you wear something tight, it means less air gets to the area and you’re more likely to sweat, which can cause irritation,”
There is an increasing focus on brown fat, a type of tissue in the body that may protect against weight gain. While ordinary body fat piles on when we eat more calories than we burn, brown fat seems to burn excess calories to generate heat.
We know babies have lots of brown fat, they need it to keep warm but studies have shown there are small amounts in the necks of adults too. Experts believe that certain activities could switch on this fat, potentially helping to burn calories at a greater rate.
In a U.S. study in the journal Diabetes, researchers found that sleeping in a cold bedroom could activate brown fat in adults. Five healthy young men slept in climate-controlled bedrooms for four months. For the first month, the room was kept at 24°C, then it was lowered to 19°C, then it went back to 24°C and for the last month raised to 27°C.
They ate the same amount of calories and their calorie expenditure and insulin sensitivity how much insulin the body needs to keep blood sugar levels stable were measured each day. The results were striking. After four weeks sleeping at 19°C, the men had almost doubled their volumes of brown fat.
Tests showed they burned more calories throughout the day when their bedroom was cooler (though not enough to lose weight) and their insulin sensitivity had also improved. Senior author, Francesco S. Celi, said the study showed that over time, sleeping in a cold bedroom could lessen the risk of diabetes. sleeping naked may be beneficial.
“Brown fat can produce 300 times more heat than any other body organ, meaning if you can keep it activated for a prolonged amount of time you’d be less likely to lay down excess energy. “So, anything you can do to try to activate it, such as lowering the thermostat and sleeping in the cold, may be of benefit,”he said.
But room temperature shouldn’t be below a level at which you feel comfortable, otherwise you won’t sleep. People who tend to feel hot at night and like to sleep naked, may have a high amount of brown fat, which causes them to feel warmer than others.
Lower blood pressure
Cosy pyjamas are tempting, but if you share a bed with a partner, going nude will generate a generous boost of oxytocin, a hormone that has been shown to have a wealth of health benefits.
“It is triggered by closeness, particularly skin-to-skin contact,”
“Sensory nerves on the skin send impulses to the brain, triggering the release. “When a baby is placed on its mother’s chest, the blood in mother and child starts to pulse with oxytocin,” he said. Oxytocin has a protective effect on the heart, as it lowers blood pressure. It also boosts the immune system and reduces anxiety. “But it only works if skin-on-skin touching is something you’re happy with,” he added.
Boost your love life
People who sleep naked have happier love lives, according to a survey of 1,000 British adults by a bedsheet company this year. The study found 57 per cent of nude sleepers were happy with their relationship, compared with 48 per cent of pyjama wearers and 43 per cent of nightie wearers (onesie wearers were just 38 per cent).
Sleeping naked is a good strategy for those with body image issues, says Denise Knowles, sex therapist at counselling charity Relate.

even if you don’t want to be looked at
