Over the years, researchers have studied sleep and have disclosed several benefits beyond providing rest for the body. They have also pointed out that it’s not just about sleeping, but length of time, temperature, position, foods and other factors can contribute to getting the best out of sleep time and reaping its numerous benefits. Recent studies have focused on how what one wears to sleep may affect his/her sleep and according to an international study by the U.S. National Sleep Foundation, sleeping in the Unclad has been shown to have numerous benefits. Experts revealed to Daily mail of UK how ditching pyjamas is the best.

1. For a good night’s sleep

Sleep experts agree it’s important to keep cool at
night as your body (or ‘core’) 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,” said Dr
Chris Idzikowski, Director of the Edinburgh Sleep
Centre, Scotland, and author of ‘Sound Asleep:
The Expert Guide To Sleeping Well.’

“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 Unclad is it’s easier
for the body to cool and maintain the lower
temperature the brain wants to achieve,” he
said.

Disrupted sleep from being too hot doesn’t just
mean you’ll 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.

2. Stop infections

Wearing nothing to bed can help women avoid
developing yeast infections, such as thrush, says
Austin Ugwumadu, a consultant gynaecologist at
St George’s Hospital in South London.

“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,” he said.

3. Burn calories

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.

Michael Symonds, professor of Developmental
Physiology at the University of Nottingham and
an expert on brown fat, says sleeping Unclad 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 Unclad, may have a high amount of brown
fat, which causes them to feel warmer than
others.

4. Lower blood pressure

Cosy pyjamas are tempting, but if you share a
bed with a partner, going Unclad will generate a
generous boost of oxytocin, a hormone that’s
been shown to have a wealth of health benefits.

“It is triggered by closeness, particularly skin-to-
skin contact,” says Dr Kerstin Uvnas-Moberg, a
physiologist at the Swedish University of
Agricultural Sciences and an expert on oxytocin.

“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.

5. Boost your love life

People who sleep Unclad 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 Unclad 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 Unclad is a good strategy for those with
body image issues, says Denise Knowles, sex
therapist at counselling charity Relate.

“You can slip under the sheets and then take
your clothes off, and then you can be touched,
even if you don’t want to be looked at.

“Pyjamas might give the message ‘not tonight,’
but equally a lot of couples have a lot of fun
taking each other’s clothes off,” she said.
