1. People with high blood pressure As soon as the skin comes into contact with cold water, the blood vessels contract sharply, and a large amount of blood rushes back to the internal organs, causing the already high blood pressure to rise further. In severe cases, it can cause cerebral blood vessel rupture, bleeding, stroke, coma, and even death. People with slightly elevated blood pressure can take cold baths, but they can only adapt slowly.
2. People with sciatica and other neuralgia Such people should not take cold showers. Because the pain will be more severe when the nerves are exposed to cold. People with arthritis and joint pain should also avoid cold baths.
3. People who are allergic to cold For example, patients with cold urticaria or winter pruritus should avoid taking cold baths during an attack. If you want to exercise your skin when the disease is not occurring, you can use the gradual cooling method, that is, take a hot bath at first, then gradually change to a warm bath, and then gradually lower the water temperature until the water temperature is quite low but the disease is not occurring.
4. People with heart disease When taking a cold shower, blood rushes to the heart rapidly, making the heart unable to bear the load. People with poor liver, kidney, and lung functions are also not suitable for taking cold showers because their organs may not be able to bear the load.
5. People who have just finished drinking After drinking, the pores of the skin are fully open. When taking a cold shower, the pores will rapidly contract due to the cold water. The impact is too great and the body cannot bear it.
6. People after intense exercise When engaging in strenuous exercise, just like drinking alcohol, you will produce heat due to sweating, which will open up all the pores of your skin. If you take a shower immediately, your body will not be able to bear it.
7. People with insufficient Qi and blood Women are not suitable for taking cold showers and doing vascular exercises during menstruation, pregnancy, and postpartum confinement because they are weak, have insufficient Qi and blood, and have poor blood circulation.
8. People who have just eaten When you eat, blood will flow to the stomach to help digest food. If you take a cold shower immediately, the blood will flow from the stomach to other internal organs of the body, affecting digestion. You should take a cold shower half an hour after a meal. Finally, a tip for friends who love cold showers: when taking a cold shower to cool down, it is not advisable to suddenly immerse your whole body in cold water at the beginning. It is best to splash some cold water on your body with your hands or the shower head, or wet your hands and feet with cold water first, then use a towel soaked in cold water to wet your chest and back, rub your body for a while before pouring cold water all over your body, wipe dry quickly until your skin turns red, and if you feel refreshed, it means that the effect is good. If you feel chills, take shorter showers or increase the water temperature. |
