Casual bathing may cause arthritis, bronchitis, asthma and other diseases. Investigation data show that all kinds of joint pain, limb numbness and rheumatic joint pain are related to taking a cold bath in summer.
People's intracranial arteries and blood vessels are very sensitive to pain, but in the hot season, the head is prone to sweating after exercise. At this time, vasodilation, if washed with cold water, may cause abnormal intracranial vascular function, and symptoms such as dizziness, black eyes and vomiting may occur during the attack. If it is serious, it may cause intracranial hemorrhage. Young people should pay attention to washing with warm water after a lot of exercise.
Suggestion 1. Don't take a cold bath immediately after sweating heavily in summer, especially after exercise. If you take a cold bath immediately, your skin will be stimulated by cold water, which will make your blood vessels contract through nerve reflex. In this way, sweating and heat dissipation will be blocked, but it will be difficult to dissipate heat, and your body temperature will rise. At the same time, the decrease of skin blood flow suddenly increases the blood flow back to the heart, which will increase the burden on the heart. When the body changes from hot environment to cold environment, it is too late to adapt and adjust, and it is often easy to catch a cold or cause gastrointestinal spasm.
It's best to take a warm bath in summer, and don't try to feel refreshed for a while, leaving hidden dangers of diseases.
People who wear light sandals and slippers in summer cannot wash their feet with cold water. This is because the sweat glands on the soles of the feet are relatively developed. Suddenly washing feet with cold water will lead to the sudden closure and blockage of pores, which will lead to poor perspiration function after a long time. At the same time, it may induce limb artery spasm, erythromelalgia, arthritis, rheumatism and so on.
4. Avoid washing your hair with cold water in summer. Some people like to wash their hair with cold water in summer, which will make them feel uncomfortable when they have a headache or feel cold in the future. And after washing your hair, it is forbidden to blow directly at the electric fan or air conditioner for a long time.
