Why you can’t sleep with the fan on

(ORDO NEWS) — When the weather is hot, the only salvation seems to be a fan. But do not turn it on when it’s time to go to bed. This type of “cooling” can cause serious health problems.

Exacerbation of allergies and asthma attacks

If you sleep with the fan on, it can cause asthma attacks or even exacerbate an allergic reaction. This can be explained by the fact that there is a lot of dust in the blades of the device, which gradually accumulates there. When the fan starts to work, all this dust spreads around the room.

During sleep, dust can easily enter not only the sinuses, but also the respiratory tract, which will be a serious problem for a person suffering from asthma or allergies.

Load on the body

Do not use the fan when the air temperature is above 30 degrees. The reason is that when the air is heated to a mark of 35 degrees, the fan can significantly increase the load on the body.

The device directs streams of hot air to a person, so sweat begins to be released more actively, which in turn leads to dehydration of the whole organism.

In addition, a person may experience symptoms that resemble heat stroke. There is a severe headache, thirst, weakness, dizziness and even nausea.

Dry skin

Fans can also have an extremely negative effect on the condition of the skin and mucous membranes of the eyes. Hot air can quickly dry out your sinuses, causing headaches or nasal congestion.


When a fan is running while a person is sleeping, it can cause chills. In the muscles there is a strong tension and even convulsions.

In addition, there is too much risk that a person may catch a cold in the neck or head, and experience very painful sensations in the ears.
