Martin Seeley, the CEO and sleep skilled at MattressNextDay, stated there are "several downsides" to sleeping with a fan on in the course of the evening.

Seeley elaborated: "Electric fans circulate air in the room, but they also stir up dust mites, spores, pollen, and other allergens.

"This can result in signs akin to extreme sneezing, watery eyes, runny nostril, itchy throats, and respiration difficulties."

Another risk of prolonged exposure to a fan is that they can "dry out the air, inflicting the physique to supply extra mucus to remain hydrated".

Seeley said: "This may end up in a stuffy nostril, sinus headache, and different discomforts."

Dry air can also lead to dry eyes and irritation, Seeley cautioned, which can be "notably problematic for contact lens wearers".

And for anyone who suffers from muscle pain, sleeping with a fan on might be a big no-no.

"Directing cool air from an electrical fan onto pre-existing muscle pains could cause muscle tissue to tense and cramp, leading to extra discomfort," said Seeley.

As the scorching heatwave can leave homes feeling far too humid at night, are there better alternatives to a fan in order to get a good night's sleep?

Seeley recommended filling up a hot water bottle with tap water and putting it into the freezer.

Then, before you nod off to sleep, you can take the frozen hot water bottle and place it inside your bed.

In addition to a frozen hot water bottle, another tip is to put pillowcases into the freezer so that at nighttime you can rest against a cooler surface.

Seeley added: "When you sweep your tooth earlier than mattress, you must also run your wrists underneath chilly water for a couple of minutes earlier than bedtime, as this rapidly cools your physique down."

While it could be tempting to open the bedroom blinds and curtains during the daytime, when it's as hot as it is, don't.

Seeley explained: "Naturally, the solar tends to be the most popular all through the day, so a high tip is to maintain your blinds and curtains shut all through the day, to stop the solar from coming in.

"This should keep your bedroom cooler at nighttime when it’s time to fall asleep."

If you actually should sleep with a fan on in the course of the evening, Seeley suggested to:

• Regularly cleansing the fan blades
• Consider an air-purifying fan
• Drinking not less than two litres of water all through the day
• Consider utilizing a rotating electrical fan.
