The negative effects of sleeping with wet hair have been debated for decades. Children have been warned by their parents that if they went to bed with their hair wet they would wake up the next day with a whole range of problems from colds and eye infections to bacteria growth in the hair. The Internet makes it easier to now dig deep and get to the bottom of the debate once and for all. Rather than dismiss the theories as just myths, arming yourself with the facts can go a long way in deciding for yourself how much risk you put yourself and your family at when exposed to the dangers of sleeping with wet hair.
The simple, if unpleasant, truth is that your pillow case acts like a magnet for different forms of bacteria and fungi growth, regardless where you live or the climate you live in. Women who go to bed with their make-up on know all too well that as their foundation and eyeliner rubs off on the pillowcase during sleep, it acts like a magnet for certain bacteria growth that then comes in contact with the face eight hours a night, day after day, until the pillowcases are washed. The same can be said when you go to bed with wet hair. The damp hair not only causes the pillowcase to become wet, but it also soaks deeper into the pillow, a bigger problem than just wetting the exterior of the pillow. During the night, the warm temperature of your head and the moisture of the pillow cause a buildup of bacteria and fungus growth. The majority of people are spending up to a third of their lives sleeping in bed, which means eight hours of your skin coming in contact with dangerous fungi growing on the pillowcase. Each night your hair is wet, the problem gets worse, and the bacteria and fungus can exacerbate many different respiratory related diseases.
