In hot summer, I like to take a bath with cold water. What's the harm to health?

Cold water is very irritating to our body. If we are stimulated by cold, our heart will speed up, our nerves will temporarily become nervous, and people with less resistance will catch a cold.

Taking a bath with cold water can increase our ability to cope with cold changes and enhance our resistance, so that our body will not feel so slight about the cold and naturally will not catch a cold so easily. We take a cold bath, which is also good for our blood circulation. Under the stimulation of cold, our blood vessels will contract one by one and become more active.

? What needs to be said is the disadvantages of taking a cold bath. In order to "enjoy" a cold bath to the maximum extent, scientific and reasonable methods should be adopted. Specifically, there are the following points: from summer, stick to it and step by step. Do a "warm-up" exercise before each cold shower: rub your skin for a few minutes until you feel red and hot.

? When taking a bath, first pour water on the limbs, and then rinse the chest and back for a few minutes to let the body have a gradual adaptation process; The water temperature should not be too low, 5℃-25℃ is appropriate, and the time should not be too long, 10- 15 minutes or so, and the longest time should not exceed half an hour. In addition, it should be noted that don't take a cold bath after strenuous exercise. Because the capillaries on the body surface dilate at this time, if you suddenly "encounter" cold water, it will increase the burden on your heart and cause discomfort such as palpitation, shortness of breath and dizziness.

? In the process of bathing, if there are symptoms such as persistent whitening and dizziness, stop immediately to avoid accidents.
