If you take a shower before bed, you might be wondering if sleeping with damp hair is a problem. You probably hear the voice of your parents or grandparents telling you that you will get sick and damage your hair. But what is it really?
The idea that catching a cold puts our health at risk is a myth firmly entrenched in our cultures. Disease-causing bacteria and viruses do not appear spontaneously, so you are not at risk of illness by lying down with wet hair. However, there is another danger: studies cited by the Time have shown that pillows, especially those made with synthetic materials, may contain mold and mushrooms asthma orallergies.
These microorganisms tend to proliferate in humid environments, just like dust mites. If you suffer from a stuffy nose, itching, tearing, and breathing problems that may indicate the presence of allergy or asthma, do not hesitate to wash your pillowcases and sheets in hot water at least once a week. This will limit exposure to irritants.
Skin, hair and sleep
As for hair and skin health, there may be legitimate reasons for wanting to avoid lying down with a wet head too often. After a few weeks or months, the water can break down the protective outer layer of the hair follicle, called the cuticle. Once this cuticle breaks down, water can penetrate it and break the inner cortex of the follicle. The resulting damage can lead to hair breakage, as well as loss of shine and elasticity.
On the skin, wet hair on the face may cause slight irritation and skin dryness. But most people who sleep with wet hair seem to have no problem. In some cases, specifies the Time, a drop in body temperature would even help to find sleep more easily. It’s up to you to weigh the pros and cons.
