Dead cells and mites

Although we are sleeping, our body continues its normal metabolic activity. So that It is possible to expel up to 15 million dead skin cells, just overnight. Which remain between the sheets and covers.

Later, to take care of these cells, the mites will arrive. Animals so tiny that they cannot be seen with the naked eye. These take advantage of any type of dirt or dust to create their population.

Found in dirty sheets, these little arachnids will not last long to reproduce. So they will multiply, increasing the number of insects every minute.

Some mites may be able to bite and penetrate the skin, causing various diseases. Among these, we can mention: scabies, scabies, pruritic dermatitis, etc.

But that is not all…

In addition to dead skin debris, traces of sweat or other body fluids, and millions of mites, dirty sheets can contain both fungi and bacteria.

A study carried out showed that Only in our pillowcase you can find as many bacteria as on a toilet seat. That's right, that place where we sit to meet certain physiological needs, such as defecation.

And we are not talking about a small number of bacteria, not even equal to the number of microbes found on the toilet seat. It is proven that in the pillowcase there can be a thousand times more bacteria than where we do our needs.


It is very important to change the bedding, at least once a week. As well as washing it with warm water and enough detergent, in such a way that all the microorganisms that are protected in the dirt of the sheets are eliminated.

Doing this is recommended, not only to sleep in a cleaner bed, which will undoubtedly make you feel much more comfortable and in comfort. But also to take care of not acquiring different diseases.
