Sorry, But Science Says Sleeping Naked In A Heatwave Is A Terrible Idea

The UK just saw its hottest May day on record, and we’ve had some unusually hot “tropical nights” (over 20C) too.

That can ruin your sleep. One paper found that heatwaves are especially ruinous, causing us to lose crucial minutes of shut-eye.

But if you’ve been sleeping in the nip for a cooler night, Natalie Pennicotte-Collier, a resident sleep expert at MattressNextDay, says you might want to reconsider.

Why shouldn’t you sleep naked in a heatwave?

It has to do with how sweat, which needs to evaporate to cool us off, behaves.

You might think that water wicks away faster when we’re naked. But the sleep expert said that’s not always true,

The move “feels logical, but without breathable natural fibre bedding to wick sweat away, moisture simply sits on the skin and creates a clammy humid ‘microclimate’ that is more likely to wake you up in the middle of the night.” Pennicotte-Collier explained.

The same logic applies to your bedsheets – we “should replace [our duvet] with a lightweight breathable layer instead of sleeping completely uncovered,” she said.

Research has her (pyjamaed) back. One paper from the University of Birmingham found that linen bedding was linked to fewer wake-ups among younger participants in hot weather.

How can I get to sleep in a heatwave?

Sleeping on a lower level in your home might help, the Red Cross said, as heat rises.

And paradoxical as it might sound, taking a warm shower might help, too.

Speaking to HuffPost UK previously, Dr Seeta Shah from PANDA London said: “Many take a cold shower before bed in hot weather, but a shockingly cold shower can actually raise core body temperature as your body works to counteract the sudden cold.

“A lukewarm to slightly cool shower is better. It gently reduces body temperature and triggers the parasympathetic nervous system, helping your body wind down and enter a sleep-conducive state.”

31°C Scorcher Set To Fall This Bank Holiday Weekend, Says Met Office

This upcoming bank holiday weekend (Friday 22-Monday 25 May) is set to be “very warm” with “plenty of sunshine,” the Met Office’s current forecast reads.

Per the BBC, some parts of the UK will see the mercury rise to 28°C on Thursday and Friday.

Though very high temperatures (hotter than the hottest day of the year so far, which was 26.6°C), those don’t necessarily mean we’ll be in an official heatwave.

Here’s where temperatures are expected to soar, what makes a heatwave a heatwave, and how long the conditions are expected to last.

Where is it expected to reach 31°C in the UK?

As of time of writing, The Met has forecast 28°C in the South-East, including London, on Saturday, 23 May, with temperatures reaching as high as 30°C on Sunday, 24 May.

And on Monday, the South-East (including London) will see a scorching 31°C, the Met’s interactive forecast map currently reads.

Other parts of the country will still be hot ― Manchester and Plymouth are expected to reach 26°C at the same time on Monday, while Cardiff will reach 27°C.

Is that a heatwave?

A heatwave officially occurs when somewhere in the UK gets a minimum of three days in a row at or above the maximum temperature threshold.

In the UK, those maximums vary. The South-East is sunnier than the rest of the UK, meaning its temperature threshold is 28°C or 27°C. London’s threshold is 28°C.

As you head further North and West, that threshold reaches 25°C and 26°C.

London is predicted to reach or exceed these temperatures on Saturday, Sunday, and Monday (Tuesday should be a scorcher too), so yes, if those predictions hold, we will be in an official heatwave. Other parts of the country, particularly in the South-East, are likely to qualify too.

How long will the heatwave last?

High pressure, which is responsible for sunny, dry conditions, is expected to last into the week following this Bank Holiday weekend, the Met Office said.

In fact, their long-range forecast reads that while we’ll likely see some rain and scattered showers in between, sunnier, warmer weather could last until “mid-June”.
