Is it safe to sleep with a fan on?

Sleeping with a fan on may present a number of disadvantages to those with allergies, asthma and hay fever.

According to The Sleep Advisors, while a fan does circulate air to make your room cooler, it can also circulate pollen and dust.

The sleep experts said: “Take a close look at your fan.

”If it’s been collecting dust on the blades, those particles are flying through the air every time you turn it on.”

If you’re prone to allergies, it could be worth trying other options like a cool flannel in a bowl of water near your bed or keeping the blinds or curtains shut to keep the room cool.

Leaving a fan running all night can also cause a stiff neck, sore muscles and dry out your skin, as well as your nasal passages.
