Cropped Hand Of Person Holding Ice

Sleeping in a heatwave is no easy feat.

As the UK braces itself for another few days of scorching temperatures, we're all looking for ways to have a half-decent (we'll even take mildly acceptable at this point) sleep.

Along with the rest of us, Good Morning Britain's host, Kate Garraway, confessed she has been sleeping terribly since the start of the heatwave.

The 53-year-old even admitted to dipping her sheets in cold water before bed.

But Dr Sarah Jarvis offered a warning to people looking for ways to cool down, advising hot Britons to avoid putting ice directly onto their skin.

Speaking on the ITV show on Tuesday 11 August, Dr Jarvis also suggested it was better to have a "cool shower" than a "cold shower" before bed, explaining that you'll still feel the benefits.

"We don't want to have a really cold shower. If you have a cool shower and then allow the water to evaporate off your skin, it will definitely help cool you down," Dr Jarvis explained.

A popular idea amongst the Good Morning Britain team was to fill a hot water bottle with cold water and put it in the freezer.

"It does work, it does help definitely," said Garraway, who has tried every trick in the book for a cool night sleep.

But Dr Jarvis warned: "Please don't forget; never put ice directly onto your skin because that can cause ice burns."

If people do choose to put hot water bottles in the fridge, they need to make sure they wrap them with a tea-towel or put some sort of fabric on top before placing them on their skin.

The same rule applies for sheets.

"A cool flannel around your neck, and possibly putting sheets in the freezer, but not risking any ice burns, can help," Dr Jarvis adds.

Speaking about some of the ways she has tried to keep cool in this bout of warm weather, Garraway admitted she has dipped her sheets in cold water before bed.

"I tried the whole dipping your bed sheet in water, it does work a bit but then you get too chilly," she explained.

With the hot weather set to continue before making way to thunderstorms later in the week, the top suggestions seem to centre around the freezer.

Usually used for leftovers and must-have heatwave ice lollies, the freezer can double up as a nice space to keep sheets and hot water bottles as temperatures soar.

No space? You'll just have to finish off the ice lollies.
