UK Weather: Experts Reveal The Best Tips To Survive Heatwave Tomorrow

 Experts Reveal The Best Tips To Survive Heatwave Tomorrow- With Britain set to bask in temperatures hotter than the Algarve tomorrow, experts have shared a host of tips on how to keep cool in the sizzling heat on ‘fiery Friday’.

From avoiding caffeine and steering clear of alcohol to putting a bowl of ice in front of a fan, popular heatwave hacks even recommend putting your bedding in the freezer.

The mercury is set to soar to 34C (93F) in the South East tomorrow, higher than the 27C (80F) expected in Faro, Portugal.

Britain’s sky-high temperatures even prompted health chiefs to issue a warning, with officials advising people to look out for older people, young children and babies and those with underlying health conditions.

But the blistering heat, which has been gaining momentum all week, will then dip to 20C (68F) on Saturday and Sunday, with thunderstorms expected.

Here, MailOnline reveals the best tips to stay cool in the heatwave — which will help you sleep through the night and avoid dehydration.

Take a warm bath before bed

While many may opt for an ice bath during the soaring temperatures today and tomorrow, experts actually recommend the opposite for staying cool at night.

Core body temperatures follow a 24-hour cycle, with levels dropping by about 2C at night. The drop in temperature allows the body to conserve energy and direct it to organs that need it.

The cycle can, however, be disrupted during periods of hot weather, potentially causing a miserable night’s sleep.

However, the science says hot baths can help you cool down rapidly.

This is because the warm water causes the blood vessels on the surface of the skin to dilate, causing the blood to rush to your extremities. Once out the bath, this causes the body to cool down rapidly.

Hayley Thistleton, sleep expert at SleepSeeker, told MailOnline: ‘It might seem like the opposite of what you should be doing to keep cool.

‘But it’s worth taking a warm bath about an hour or two before bedtime as this helps your body temperature to decrease after you leave the bath and your body adapts to the cooler environment.’

Eat spicy food

Forget taste, there may be another reason why the hottest countries in the world in South Asia, Africa and the Caribbean all love eating spicy food.

Despite also seeming counterproductive, extra hot dishes can actually cool you down.

Spicy food raises your internal body temperature, mirroring that of the weather.

This causes you to sweat and once your body heat has been used to evaporate the moisture you start to cool off.

Unlike downing a cold drink or having an ice cream — which causes your body to raise its temperature after it drops too rapidly — this causes a long-lasting cooling effect.

Dave Gibson, from the Sleep Site, recommends you eat spicy food at least three hours before bed during the heatwave.

Put your bedding in the freezer 

After a long day in the sun, everyone wants to return to a nice cold bed.

As with the hot bath trick before bed, relaxing into cool sheets helps allow the body’s temperature to drop by the required 2C needed for good sleep.

But rather than causing your body to radiate heat away, this directly cools you from the outside in, preventing your internal temperature from jumping back up as it readjusts to the outside.

Dr Mike Farquhar, a consultant in sleep medicine at Evelina London Children’s Hospital, said putting bedding in the freezer for a couple of minutes at night will help you stay cool throughout your sleep.

But make sure the bedding is put in plastic bags first to prevent dirty bedding from contaminating food, or vice versa.

Try ice in front of the fan

With most Britons not having an air conditioning unit in their home, many turn to placing ice in front of their electric fan.

The popular DIY hack — is backed by consumer advice company Which? — can help circulate chilled air across the room.

It works quite simply: the air around the ice drops to near-freezing temperatures and the fan helps push this across the room.

Experts at the Good Housekeeping Institute said: ‘As the air passes over the ice it will be chilled and will circulate refreshingly cold air around the room.’

But make sure any ice is either in the bowel or kept in a bottle to avoid water getting into the fan’s electrics when it melts.

Avoid caffeine and alcohol

Caffeinated drinks like tea and coffee can cause dehydration, which is one of the greatest risk factors faced during the heatwave.

The same is the case with alcohol, with excessive beers and cocktails in the sun all putting Britons at risk of becoming dehydrated.

Caffeine and alcohol both suppress the hormone ADH, which usually causes the kidney to retain water when your body is low on stores.

This causes you to urinate more frequently than you should, resulting in dehydration.

Dehydration can cause splitting headaches and even result in hospitalization if you reach the point of nausea and are unable to drink water as a result.

Dr Louise Smith, director of public health for Norfolk County Council, told people to avoid drinking alcohol and caffeine where possible.

She said: ‘It’s vital to stay cool, drink plenty of water and avoid excessive alcohol or caffeine. These are simple things we all know we can do and if we make time to do them, we can safely and happily enjoy the summer weather.’

Despite being a mild diuretic — causing urination — some experts have questioned coffee and tea’s dehydrating effect, suggesting the loss of fluids caused is replaced by the drinks themselves.

Wear loose-fitting clothes

Linen shirts and summer dresses are ideal for beating the blazing sun.

Tight-fitting clothing can cause you to feel warm by creating an insulating layer of air between your body and the outside world.

TV doctor Dr Hilary Jones warned old people should make sure they wear loose-fitting clothes — and less of them — or risk feeling faint and falling.

The GP told Good Morning Britain: ‘It makes sense to drink plenty of water, stay in the shade and wear loose-fitting clothes.

‘A lot of elderly people I know come into the surgery — they’ve got too many clothes on, so they feel dizzy and they feel faint, and they’re at risk of falling.

‘Not something you’d associate with warm weather, but that’s how it happens.’

Unplug your chargers

Electric chargers are another unexpected source of unnecessary heat, with experts advising people unplug all devices before bed and move them to another room while sleeping.

Chargers can cause devices to overheat — especially when they are already warmed by the weather — which will cause a source of heat in rooms.

Experts recommend unplugging devices as soon as they reach 100 per cent, preventing them from reaching temperatures that are too high.
