People who are busy working during the day often only have time to do their own things at night, such as washing their hair. Washing hair is originally for maintaining the health and hygiene of hair, but frequently washing hair before bed can be harmful to the body. Let's learn about it together.
Easily leads to colds
Washing hair before bed and sleeping with wet hair can easily lead to colds. The human body has a temperature regulation system. When washing hair, the capillaries expand and the body releases more heat. In addition, a large amount of heat is taken away when the moisture in the wet hair evaporates. If you sleep with wet hair, your body temperature will drop and you are more likely to catch a cold, especially for people with weaker constitutions who are more susceptible to virus invasion and colds.
Affects sleep quality
Washing hair before bed and sleeping with wet hair can easily affect sleep quality. This is because washing hair before bed stimulates the hair with warm water and makes the brain nerves excited, making it difficult to fall asleep. In addition, sleeping with wet hair can easily cause the scalp to become damp and cold, resulting in insomnia, frequent dreams, and restless sleep.
Causes headaches and other injuries
Washing hair before bed and sleeping with wet hair can easily cause headaches. This is because when the hair is not dry, the body's capillaries will undergo local ischemia and spasms due to cold stimulation, leading to headaches. Especially for people who wash their hair in summer and sleep in air-conditioned rooms, this symptom is more likely to occur.
Causes menstrual pain in women
Washing hair before bed and sleeping with wet hair can easily cause menstrual pain and other discomfort during the menstrual period for women. This is because sleeping with wet hair allows the head to be invaded by cold air, which can easily cause blood stasis and result in menstrual pain and other problems.
Increases internal dampness
Washing hair before bed and sleeping with wet hair can easily increase internal dampness. This is because sleeping with wet hair easily brings cold and dampness into the body, making the body's internal dampness heavier. You can check if you feel sticky in your mouth, have loose stools, or experience leg swelling when you wake up in the morning. These symptoms indicate that there is excessive internal dampness.
How to wash hair at night to minimize damage
If you must wash your hair at night, you should try to wash it earlier to allow time for it to dry. If that's not possible, use a drying powder or a dry towel to dry your hair before sleeping. In summer, avoid sleeping with wet hair under air conditioning or fans blowing directly on your head. Additionally, it is important to engage in regular physical exercise to enhance the body's resistance.
