Encasing too warm – how do you get a comfortable sleeping environment?

The desire to improve sleep is associated with the use of encasing At night you want to suffer less from the symptoms of house dust allergies and find your way to sleep more easily.

It is important for the quality of sleep that it is neither too warm nor too cold in bed . Do you have the feeling or the fear that an encasing leads to more warmth and that it does not achieve the desired effect ?

You can do this if your encasing is too warm and you prefer it cooler.

The encasing is pulled over the mattress and pillow as a cover. This prevents you from coming into direct contact with the mites and their excretions. For this purpose, encasings are made of a fine fabric. These are designed in such a way that even the finest particles can no longer get through. As an allergy sufferer, you will no longer come into contact with the allergens and your symptoms will decrease.

Ideally, the encasing should not have a noticeable effect on the sleeping environment. Modern and high-quality designs are designed to be air-permeable . This does not change the properties of your pillow or mattress. Your sleeping climate remains unaffected.

It looks different if you opt for cheap encasings . These also prove to be effective and do not let the allergens or other particles through, but the air permeability is less than optimal. Because the tissue alone is not responsible for the high effectiveness. In addition, some inexpensive encasings consist of chemical coatings. The coatings are barely breathable, so it gets warmer in bed. Moisture is more likely to collect and you will start sweating faster.

So it can happen that encasings influence the sleeping climate. However, this is not the case with modern high-quality materials. Encasings made from Evolon offer protection without changing the sleeping climate .


Have you decided on an encasing and it turns out to be too warm in use? Then the following measures remain in order to manage the heat better and to spend the night comfortably.


If the encasing is too warm, this is probably due to the material used . Possibly it is a cheap model, the quality of which is hardly convincing. If chemically treated textiles are used, this can lead to the heat.

After using it, it is unfortunately no longer possible to exchange the encasing. These are hygiene products that cannot be returned . Therefore, you have no choice but to buy a new version .

If you would like to test this for the thermal properties, then try it out in a specialist shop. With a fabric sample, you can better assess whether the material is proving to be a heat trap or whether it continues to offer high air permeability.


If the protective cover is used in the cot, you may be able to do without it in summer. Use a mat and bedding that is easy to wash at high temperatures. At temperatures above 60 ° C, the mites die, so that the sleeping environment becomes hygienically clean again.

Also make sure that there are no cuddly toys in the cot . These are considered a place of well-being for mites and in most cases worsen the symptoms.

If your child suffers from a very weak house dust allergy, it is absolutely advisable to forego the allergy covers in summer . Put more emphasis on an allergy-friendly environment so that your child gets a comfortable sleep.


If the covers prove to be comfortable and you don’t want to exchange them, you can create a cooler sleeping environment in other ways .

The easiest option is to install air conditioning in the bedroom. This cools the room down to a pleasant 18 ° C, so that you don’t have to suffer from the high temperatures even in midsummer. However, air conditioning is associated with high costs and landlords are often opposed to such structural changes being carried out.

As an alternative for the summer, you can use pillows and bed linen that have a cooling effect. Especially with pillows, there are some variants that noticeably lower the temperature when you lie on them.

Otherwise it is advisable to change the ventilation behavior . Only keep the windows open at night in summer and darken the bedroom during the day. This makes it harder for the heat to penetrate and it stays cooler overall.


It is by no means the case that encasings contribute to a warmer sleeping environment. Modern designs with an air-permeable material prove to be effective and do not change the sleeping climate.

If you sweat due to the use of the protective covers, it is usually an inferior material that is barely breathable . Exchange the encasings for higher quality versions and ask your health insurance company whether they will make an additional payment. Then you will receive comfortable covers that promote your sleep and with which you will not break a sweat even in summer.

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.
