Experts have discovered why no one should sleep with a fan on overnight despite extreme temperatures Heatwave in UK.
Temperatures are supposed to rise into the high 30s in some areas on Monday, while Tuesday is expected to be even hotter with temperatures potentially reaching 40C (104F).
That would be a new record for Great Britainwhich beats the 38.7 °C (101.7 °F) observed in Cambridge in 2019.
As Brits turn to sleep in the sweltering heat, many are opting for a bedside fan to help drift off in sweltering temperatures.
However, experts have warned that running a fan overnight can have negative effects on your health, especially if you suffer from allergies and/or asthma.
Sleeping with the fan on could cause pollen and dust to circulate into the albeit cooler air.
One expert explained how “concentrated cool air can make muscles tense and cramp.” It can also dry out your nasal passages, which can cause your body to produce more mucus and make you feel congested when you wake up.
Experts have warned against taking a close look at your fan. If dust has accumulated on the blades, this dust circulates overnight.
But in more positive news for those who struggle to sleep at night in hot temperatures, the Met Office predicts the sizzling temperatures won’t last for too long.
The Met Office said: “A cold front from the north is creating greater uncertainty about how long Saturday’s highest temperatures will last, with areas in the south-east currently most likely to hold on to the heat, although the extent is yet to be determined.”
