Don't take a shower after a meal, don't wash your brain after drinking

The proverb says, "Don't take a shower after a meal, and don't wash your hair after drinking." What it literally means is that it is best not to take a shower immediately after a meal, and you can't wash your hair after drinking. This seemingly simple proverb actually contains health-preserving knowledge that can help prolong life.

After eating, the human digestive system starts working, a large amount of blood circulates in the stomach, and the blood flow to other organs decreases accordingly. Taking a bath at this time will increase blood flow to the skin and muscles, and the stomach will not have enough blood, which will affect the digestion and absorption of food. Although bathing is not a strenuous exercise, for elderly people with cardiovascular and cerebrovascular diseases, taking a bath immediately after a meal may cause myocardial ischemia and trigger a sudden onset of cardiovascular and cerebrovascular diseases. Therefore, it is best to take a bath one or two hours after a meal. You can choose the time to take a bath according to your physical condition. For example, an elderly person with a weak physical condition can choose to take a bath at noon when the yang energy is at its strongest. This can achieve a complementary effect and prevent them from getting sick easily.

Many people like to have a drink or two. If they wash their hair shortly after drinking, it is likely to cause abnormal function of intracranial blood vessels, resulting in symptoms such as dizziness, black eyes and vomiting. Elderly people with cardiovascular and cerebrovascular diseases should not wash their hair with too cold water, and should be more careful after drinking. Some elderly people like to go out for a walk after drinking. If they encounter cold wind at this time, the wind and cold evil will take advantage of the opportunity to enter.
