Many people have this habit. They like to take a cold bath in summer, especially after exercise, because they feel particularly cool, but although they are comfortable at that time, they are likely to feel weak or even have a headache afterwards. This is because when people sweat a lot, the capillaries are dilated. If the blood vessels are directly washed with cold water, the heat in the body is extremely contracted and bound by external forces, and it cannot be emitted for a while. However, intracranial arteries are rich in blood vessels and sensitive to external stimuli. In high temperature environment, it is easy for the head to sweat after exercise. At this time, if it is washed directly with cold water, it may cause abnormal intracranial vascular function, dizziness, headache, blackness at the moment, and even vomiting, and even serious intracranial hemorrhage, affecting life and health.

Especially for women, taking a cold bath can cause many diseases and cause low immunity. Taking a cold bath for a long time can easily lead to cold hands and feet invading the body, and long-term fatigue and joint pain. Women who take a cold bath are more likely to suffer from gynecological diseases, such as vaginitis and pelvic inflammatory disease. At the same time, taking a cold bath for a long time can cause endocrine disorders and abdominal pain. In addition, harmful bacteria in cold water will take the opportunity to enter the vagina, causing gynecological diseases.

Therefore, it is not reliable to take a cold bath online, which will increase immunity and even affect health.

You also need to pay attention to these situations when taking a shower.

You should not take a bath if you are too full and hungry. After a full meal, the blood vessels of the whole body are stimulated by hot air, and more swollen blood flows to the body surface, so the blood supply in the abdominal cavity will be relatively reduced, which will affect digestion and absorption. It is generally recommended to take a bath one hour after meals. Taking a bath with an empty stomach can easily lead to hypoglycemia and even fainting.

It is not advisable to take a bath after drinking. Taking a bath after drinking, blood sugar can not be replenished in time, which is prone to dizziness. In severe cases, hypoglycemia will lead to coma.

To sum up, I suggest you take a warm bath instead of believing that the so-called cold bath can strengthen your body.
