Summer heat: Can sleeping with the fan running pose a health hazard?

Does the use of fans lead to health risks?

Especially in the warm summer months, many people have problems sleeping properly. All windows are then opened to cool them down, and sufferers often use a fan in their bedroom. But is the use of a fan recommended during heat waves or can it even cause serious health problems?

Public Health England experts released an official guide to heat wave behavior. This guide also provides advice and warnings on the use of a fan in heat waves.

Using fans can lead to health problems

In warm weather, many people not only have their bedroom windows open all night, they also use a fan. For most people, a fan in the bedroom should do its job, but there are also people who can develop serious health problems as a result.

Exposure to dust and pollen increases

The air set in motion by the fan carries dust and pollen with it, which are blown exactly to the sleeping people. There they are then inhaled by those affected. However, this is not only bad news for all people with allergies, asthma and hay fever, healthy people are also affected by the effects, the experts explain.

Effects of using a fan

The dry air through the fan can also dry out our skin and mucous membranes, so it is important to provide the skin with sufficient moisture. The use of a fan can also cause dry eyes. The dryness makes the eyes particularly irritable, and this increases again when those affected are wearing contact lenses. At best, the fan should always be at a distance from the user, so the drying out of the skin and mucous membranes can be reduced, the experts emphasize.

Follow this advice

If you are looking for an alternative to a fan to keep your bedroom cool even in warm temperatures, here are some tips you can try. For example, you can hang a wet cloth in front of an open window to cool the temperature in the room. Closing the curtains during the day will also keep the room cooler. It is also important to pay attention to the correct bedding. Avoid, for example, silk and satin bed linen and switch to cooler bed linen and cotton sheets, the experts advise. If you follow this advice, you should actually be able to get through the warm season without problems and still stay healthy. Because nobody wants to be sick in bed in the summer heat. (as)
