Sleeping with a fan – is it unhealthy?

When the temperature rises and the bedroom looks more like an oven, you would like to cool down . In Germany only a few apartments are equipped with air conditioning. That’s why fans next to the bed are often used for sleeping. But is this cooling effect even healthy during the heat or does it affect your sleep?

You can find out whether the fan is healthy when you sleep in this guide.

If you sleep poorly in summer, it is obvious to use the fan to improve sleep. In the following you will find out what advantages the fan brings with it.

COOLING

The main reason for using the fan next to the bed on summer nights is the cooling effect . With a simple fan, the environment is not actually cooled, but the perceived temperature drops due to the constant draft.

Heat is dissipated better from the body and so it appears to you as if the room is cooler, although the temperature remains unchanged . This effect is stronger when the air hits your skin. So if you sleep in short clothes or naked , the cooling effect is perceived as more intense.

AIR CIRCULATION

The air quality in the bedroom can decrease significantly in summer. If you keep the windows closed during the day so that the warm air does not get into the bedroom, it can quickly become stuffy . A musty smell in the bedroom can arise. It is also useful for people with allergies to use a fan to bring fresh air into the bedroom.

In the evening, sleeping with the fan running is a nice support in bed to stimulate air circulation. If you open the window and use the fan while you sleep, the air is circulated faster and the air quality is increased. This means there is no lack of oxygen and you can recover better.

PLEASANT NOISES

The fan is often used for sleeping not only for cooling, but also to suppress ambient noise . If you are sensitive to noises and these disturb your sleep, you will love the monotonous fan. This always sounds the same and is able to create a calm atmosphere.

If the roommates are still active or the neighbor is a bit louder again, you can ensure a pleasant rest with the fan . Similar to a white noise device , the fan superimposes any background noise and contributes to relaxation.

WHAT ARE THE DISADVANTAGES?

As pleasant as it can be to sleep with the fan running, there are also “side effects” caused by the constant draft.

DRYNESS

The constant flow of air can dry out the mucous membranes and the skin. You can counteract this effect with moisturizers, but it should not be a permanent condition that your skin is attacked. If you notice that your skin is suffering, turn the fan down or do without it altogether.

Another danger is that the eyes are not completely closed. The air flow can irritate the eyes and the reddening of the eyes can be noticeable in the morning.

If the nasal mucous membranes dry out, more nasal secretions are produced. Dehydration should be prevented by excreting the secretion. So you will suffer from a runny nose and you may wake up with a stuffy nose.

ALLERGIC REACTION

If you suffer from a house dust allergy or are allergic to pollen, using the fan could also be disadvantageous for you. Since no new “clean” air is used, only the room air is circulated, the fan could only stir up the dust. Pollen is distributed better in the room and is a higher burden in the case of allergies.

If the allergens have already settled on the floor, they are now set in motion again by the fan. This increases the concentration of allergens in the air you breathe and is a burden for you. This is associated with typical symptoms such as a runny nose, reddening of the eyes and a cough. In severe cases, difficulty breathing during the night due to the ventilator could occur. Sleeping with a fan is not recommended for allergy sufferers.

MUSCULAR PROBLEMS

The muscles are very sensitive to room temperature. If the fan is running in the bedroom and you have exercised extensively, this could have negative effects.

Because the fan is often associated with a stiff neck and muscle tension . The fan does not cool directly, but the constant drafts in the bed still cool the body. At the muscular level, tension is possible and regeneration is limited. A little warmth is definitely beneficial for the muscles in order to be recovered the next day.

DOES THE FAN CAUSE A COLD?

Using the fan while sleeping does not directly cause a cold. Used moderately, it can promote your sleep and thus also strengthen the immune system.

On the other hand, it becomes problematic if the fan is so strong that it dries out your mucous membranes. This makes it easier for viruses to enter the body and are not so effectively fought.

Remember that the common cold is not caused directly by the cold, but by the weakening of the immune system. If the fan is too strong, it affects the immune system and can actually increase the risk of catching a cold.

WHO IS THE FAN USEFUL FOR?

If used moderately, the fan is useful for some people and helps promote sleep.

For example, if you tend to sweat very quickly in the heat, it makes sense to use the fan. This cools your body temperature and prevents you from waking up bathed in sweat at night. Nobody wants to wake up on a damp mattress. Not only is this uncomfortable, but it can contribute to a cold and reduce the quality of sleep. In addition to the fan in the bedroom, you can also use a breathable mattress . The Vesgantti mattress is a light model with a spring core, which promotes breathability.

If you are very sensitive to noises and quickly feel disturbed, the fan is also a useful utensil when you sleep. If your partner snores , you can use a fan to remedy the situation. If the fan alone doesn’t help enough, try an anti-snoring pillow .

The use of the fan while sleeping should help to lower the risk of sudden infant death. The causes of this death are not completely resolved, but the fan prevents overheating and the used air is better transported away. This increases the quality of the air you breathe and your baby will sleep better.

So there are some good reasons to sleep with the fan on. Make sure that this is set to a moderate level and rather do without it if there are health problems. Sleeping with a fan is definitely an advantage on hot days and the monotonous noise also helps against noise. You should find out for yourself whether it promotes your sleep and use the fan for a few nights.

Hello, I’m Jamie Clark, 32 years old, and I have been living in the USA for a few years.
Since I was a child, I have suffered from a house dust allergy, severely affecting me. I felt the effects both while exercising and while sleeping. Constant sneezing after getting up and difficult breathing were the consequences. The allergy has also developed into asthma, which is still a sporting restriction today.
