The main purpose of bathing in summer is still to drive away dirt and dirt, take away heat from the surface and deep part of the body, which requires warm water to improve body temperature, promote pore opening and accelerate perspiration, which can not only help the body to dissipate heat, but also relax the muscle tissue of the whole body, and even remove dirt and oil. Let’s introduce science for you: how to take a bath in hot weather?
How to take a bath in a hot day?
For example, many people think that cold water bath is the best in such a hot day! But experts cautioned that when taking a cold bath, the human body will produce a series of stress reactions due to cold stimulation, such as rapid heartbeat, high blood pressure, muscle contraction, nervous tension, etc., which not only can not eliminate fatigue, but also can easily cause cold if the resistance is poor.
Since it’s not good to take a cold bath at ordinary times, is it OK to take a cold bath when you are sweating? And it’s bad for your health. Because when the temperature rises, sweat glands, the “radiator” on the body surface, will secrete a large amount of sweat and emit heat in the body. At this time, if the skin is suddenly stimulated by cold water, the blood vessels in the expanded state under the skin will immediately contract, the secretion of sweat glands will stop, blocking the body’s heat dissipation “gate”, and the heat will not be emitted and stored in the body, which will further affect health.
It’s not good to take a cold bath, then take hot water. Many people like to take a hot bath immediately after exercise, thinking it’s easy to eliminate fatigue. However, when people are doing strenuous exercise, the blood supply to muscles increases and the heart rate increases. If you take a hot bath immediately after exercise, the blood vessels of skin muscles will further expand, the blood flow will increase, and the blood supply of the heart and brain will be insufficient. Some people will feel dizzy, flustered and short of breath, which can cause serious heart disease.
The right way is to do more than 5 minutes of relaxing and finishing activities after exercise, and then take a bath with warm water after the sweat is dry. Dropping a few drops of Aeolian essence in the water can relieve fatigue more quickly.
Warm tip: it’s better to take a bath 1-2 hours after meals. It’s better not to take a bath too long. It’s better not to take more than half an hour to avoid hypoxia caused by long-term hot air in the bathroom.
