Washing your head at night affects your health

Do you have the habit of hoeing at night?

I believe many people have answers.

  It is not difficult to understand that modern people’s life rhythm is relatively tight, and daytime work, activities, entertainment, etc. are too busy to come, it is rare to have a comfortable night to wash your head.

  After washing your hair at night, if you have enough time to let your hair dry before you sleep, then of course it is best.

But sometimes it was too busy. After 10 o’clock in the evening, I washed my hair. After washing my head, I was so tired that my eyelids were heavy enough to open, so I went to sleep when my hair was not dry.

  In this way, older generations will say that they will have headaches in the future. In fact, after modern scientific research, people find that this is not unreasonable.

  In connection with body temperature regulation, we must know that in the metabolism process, the human body constantly generates heat to maintain body temperature. These maintenance also enter the surface of the body through circulating blood circulation, through radiation, penetration, convection and evaporation.The ground is released to the outside.

  Reminder: Now the shampoo shop is located in the streets and alleys of urban and rural areas. As a kind of leisure place, it is a kind of enjoyment to relax and wash your hair and relax.

But experts believe that this fashion approach may be detrimental to human health.

  For people with strong body resistance, the body temperature regulation function is normal. Through regulation, the two processes of heat production and heat dissipation are balanced, that is, when the body temperature rises and falls, the heat production increases, the heat dissipation decreases, and the body temperature remains at 37 °C.about.
  However, for people with weak body resistance, their ability to automatically adjust body temperature makes the body maintain normal body temperature, so it is easy to catch cold when the whole body or part of it is cold.

  After we wash the hair with hot water, the scalp capillaries expand due to the warming effect, and the volume of the body radiating to the surroundings increases. At the same time, since the hair is wet after shampooing, a large amount of water evaporates and takes away a lot.volume.
Generally, one gram of water is evaporated to take away the 500 card transition.

  As the heat is increased, the body is frozen, thereby reflexively contracting the capillaries of the upper respiratory tract, reducing the local blood flow, and reducing the resistance of the upper respiratory tract, so that the virus or bacteria already existing in the local area can be taken in, grow and multiply, resulting inUpper respiratory tract infection, so there are symptoms of cold, such as runny nose, stuffy nose, headache and even fever.

  If the hair is asleep while the hair is not dry, the adjustment function of the body temperature regulating center is lowered, and the cold is more likely to occur.

  Therefore, in general, it is best not to wash your hair before going to sleep. If you want to wash, dry it with a dry towel, then use the air tube to dry the hair before you sleep, so that you will not catch a cold.

  I fell asleep when my hair was not dry, and I was prone to catch a cold.
