In hot summer, when I come home sweating like a pig, I always want to take a cold bath. However, people in poor health may have symptoms such as limited neck movement and numbness of hands and feet. Especially when you just get home, it's best not to blow the air conditioner or take a shower immediately.

Cold water shampoo bursts blood vessels. After exercise, blood flows quickly, blood vessels dilate, blood vessels contract immediately when cold water is poured, while blood is still flowing rapidly, and blood vessel pressure rises immediately. When blood vessels contract too fast, they will naturally rupture and even endanger life.

Reminder: Don't take a bath with a whole basin of cold water when people are hot from exercise. Even if they like to take a cold bath, it is best to wipe it with a wet towel first to cool down and slow down the blood flow.

Cold sleep: easy to get yin and summer heat

When enjoying the cool, don't be under the eaves or in the aisles, and stay away from the cracks in doors and windows to prevent thieves from invading and getting cold. It is best to exercise in the early morning or evening. It is not advisable to do excessive strenuous exercise. Sweating too much will not only hurt yin, but also hurt yang.
