The temperature of the bath water should be close to the body temperature, which is 35-37 degrees. When the water temperature is too high, the blood vessels in the epidermis of the whole body dilate, and the blood flow in the heart and brain decreases, resulting in hypoxia. Take a cold bath in summer. If the bath water is too cold, the pores of the skin will suddenly close, and the heat in the body will not be emitted because of the sudden contraction of blood vessels. Especially on hot nights, people often feel weak limbs, shoulder and knee pain and abdominal pain after taking a cold bath, and even become the inducing factors of arthritis and chronic gastrointestinal diseases. Generally, it is better to take a cold bath in summer, and the water temperature is not lower than 10 degrees.
Sweating after exercise in summer is inevitable. Many people like to take a cold bath at this time and feel very happy. However, sports experts suggest that taking a hot bath after exercise in summer is better than taking a cold bath, especially when you are sweating all over.
When pregnant women take a bath, the water temperature should not be too high to prevent fetal hypoxia and affect fetal development.
If you bathe your child with thread, you can't feel the soup with your hands. Just a warm feeling. If it is winter, use slightly warmer water, 40 degrees. You can try a bath thermometer. Your child's bath water temperature is 37-40 degrees, about 37 degrees in summer and 40 degrees in winter.
In the cold winter, taking a hot bath is a pleasure for many people. But if the water temperature is too high, not only the heart will produce high load, but also the skin will become extremely dry and the capillaries will burst.
In addition, there are many stresses on bathing in winter. The first is the water temperature. The suitable water temperature for bathing in winter is 37℃ to 42℃, which is 3℃ higher than human body temperature. Moreover, bathing in winter should start from the feet, because the skin temperature in winter is lower than the bathing water temperature, and the bathing water temperature in winter is higher than that in summer. Sudden hot water will bring too much load to the heart. In addition, the bathing time should not exceed 15 minutes.
