Sleeping with wet hair for a long time is like a wet rag that is not washed or dried, and there will be a lot of bacteria and fungi multiplying on the scalp, and one of the fungi that likes this kind of humid environment the most is Malassezia.
It is a conditionally pathogenic bacterium that parasitizes the human body and prefers to colonize moist and oil-rich areas. Normally it can coexist peacefully with us, but if your immunity is compromised, and if you sleep with wet hair for a long time and cause Malassezia to multiply, it can become a dangerous fungus that causes disease.

But how does Malassezia have to do with cancer?
The latest research by Nature found that the number of fungi in the pancreas of pancreatic cancer patients is 3,000 times that of the pancreas of normal people, and the most important fungus is Malassezia. Studies have suggested that Malassezia directly promotes the growth of pancreatic cancer. And the first ** of this fungus may come from your scalp.

The dangers of sleeping with wet hair.
1. Damage to hair.
When we just wash our hair, our hair cuticle will be in a state of expansion, so this time period is not suitable for squeezing and rubbing with other substances for a long time, and if we sleep with our head resting on the pillow, it will inevitably form a kind of friction, which will lead to damage to our hair cuticle.
2. Cause hair loss.
Sleeping with wet hair is also easy to cause hair loss, mainly because our scalp is irritated, for example, it is too cold, which will cause the blood circulation in our head to slow down, and the epidermis of the scalp itself is in the control center of our brain, and after being stimulated by blood circulation, it will cause hair to fall out.
Finally, some people may ask, is there anything wrong with wet hair during the day at night?In fact, wet hair is not a problem during the day, because a well-ventilated environment during the day will greatly reduce the possibility of Malassezia colonization. Then it is best to wash the bedding at least once a week, try to ensure that it is dried in the sun after washing, and avoid providing a humid environment for fungi to multiply.
