Ever wondered if sleeping with a fan on was actually doing more than keeping you cool?
For some people, having a ceiling or floor fan in the room helps them fall asleep and stay cool during the night. For others, it can trigger asthma attacks, or dry out their eyes.
Researchers have found that leaving the fan on can lead to dehydration and the drying of the mouth and nasal passages as a result of sweat and moisture evaporating from the body.
In a dry climate, these consequences can manifest even more quickly. However, a cup of water generally is sufficient to restore your water balance
The air from a fan can dry out your skin and eyes. Soothing eye drops and moisturising your skin may help you avoid these symptoms
Sleeping with a fan on is not recommended if you have allergies.
Researchers have found that the wind can assist in the circulation of allergen particles, increasing your risk of asthma, dry eyes, eye allergies, and hay fever.
Although exposure to cold can cause muscle cramps, fans can give you concentrated and constant cool air blown directly at you. In that case, the air blowing from the fan can increase your core temperature, leading to heat-related illnesses, such as nausea and headaches
