Indeed, every night we deposit 15 million dead skin cells onto ourpillowcases. These cells will not simply accumulate on the pillowcase but will feed the hundreds of thousands of dust mites that are also present. The less the pillowcase is washed, the more food the mites will be fed and the more they will be able to reproduce.
In addition, the multiplication of dust mite excreta will lead to a rapid increase in bacteria and fungi on your pillowcase.
Dangerous for the health
If you have dust allergies, dust mites can harm you. They produce proteins that irritate your eyes, make your nose runny and give you other symptoms that could feel like a cold.
According to one study, an unwashed pillowcase has 16 different species of fungi that can potentially be dangerous to the lungs and other organs.
