Leaving a fan on all night is bad for your health. The device does not only spread cold air. Dust and pollen are also blown through your room by a fan. This is especially bad for you if you suffer from hay fever, asthma or allergies. But even if you don’t suffer from anything, this is anything but healthy.
Sleeping with a fan is unhealthy
In addition, it is not only bad for your respiratory system, but also for your skin and eyes. The air is constantly moving and that causes dehydration. Chances are you wake up with dry itchy eyes. Your nose doesn’t like it either and will therefore make extra mucus. You wake up the next morning with a stuffy nose. Not the best start to the day.
And it doesn’t stop there, because a fan can cause even more misery. The cold air causes your muscles to cramp. That is not so bad for a while, but a whole night can have unpleasant consequences. For example, sleeping with a fan on can cause you to wake up with a stiff neck the next day.
