Heatwave fan

By Naomi Berners

If you've taken to leaving an electric fan on during the night to help keep you cool, it might be doing you more harm than good.

As the heatwave rages on, Brits are digging out their tower fans and setting them at full speed in desperate attempts to cool down.

But if you've taken to leaving yours on overnight, it may be doing you more harm than good.


First off, the nice cool breeze that you think is helping you drift off into a not-so-sweaty sleep is actually circulating all the dust and pollen in the room, causing a build up in your sinuses and potentially triggering asthma or similar allergies.

But the fan drama doesn't end there; the constant blast of regurgitated air will also ultimately dry out your skin. Similarly, it can dry out your throat, and even your eyes - if you're prone to sleeping with them half open.

Sinus irritation can also strike, causing blocked noses as the body attempts to try and produce extra mucus in its dry state (lovely), as well as stuffiness and headaches.

If you're finding yourself waking up with aching muscles, this could also be the fan's fault. Concentrated cool air can cause muscles to tense and cramp.

If you sleep with it close to your face, you may find your neck is super stiff the next morning.

With this heatwave refusing to budge, Brits will now have a difficult decision; sleep in a pit of sweat or risk dry skin and sinuses, achey muscles and a flare-up of allergies.

Happy summer everyone!
