What are the methods of sleep health care?

1. Moderate bed-rest health care method: After waking up in the morning, lie in bed for a few minutes, blink, rub the back of your head, stretch your limbs, and get up again, so that all organs of the human body have enough time to prepare for departure and running. Just as a car needs to be put into gear gradually when it starts, and the motor needs to be accelerated gradually when it rotates, it always takes a process and time for the human body to go from a state of lying still for 8 hours, where vagus nerve is excited and sympathetic nerve is inhibited, to an active state where sympathetic nerve is excited and sympathetic nerve is inhibited. Therefore, moderate bed rest is good for physical and mental health. You might as well wake up a few minutes earlier and get up a few minutes later.

2. Don't sleep with wet hair: If you sleep with wet hair after shampooing at night, the water vapor in the hair will gradually evaporate, taking away the heat of the human body, so that the expanded scalp capillaries will gradually contract due to cold, and the capillaries of the upper respiratory tract will contract conditionally, which will make the body catch cold, local blood supply is insufficient, and the function of the thermoregulation center will decline; In addition, when the pillow is soaked at night to cool down, bacteria and viruses accumulated near the upper respiratory tract will take advantage of it, which will make the shampoo (especially long-haired women) have cold symptoms such as headache, stuffy nose and low fever. Therefore, it is advisable to blow dry your hair with a hair dryer before going to sleep.
