While fans are an ideal way to stay cool for short periods of time, keeping them on all night may have several negative impacts on your health, according to Sleep Advisor reports.
And it’s not good news for those who suffer from allergies or asthma because dozing off with a fan on could end up circulating not just air but pollen and dust as well.
The Sleep Advisor says; “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”.
Leaving a fan on all night can also have bad consequences for your skin leaving it feeling and looking dry.
The constant airstream can also have the same effect on your eyes and mouth especially those who sleep with them partially open.
Sleep Advisor also warned the cool air could result in you waking up in the morning feeling stiff particularly those who position the fan on their neck and face.
The experts explained that this is because the concentrated cool air can make muscles tense up and cramp.
