Benefits of sweating in a bath

Taking a bath is a comfortable thing that many people like to do. A proper bath can not only relax the body and mind and relieve tension, but also help the body excrete toxins and help people shape their bodies and lose weight. People usually sweat when taking a bath, and moderate sweating can greatly promote human health. Below, I will introduce to you in detail the benefits of sweating after taking a bath!

1. Promote blood circulation

Soon after you enter the tub you can feel your inner core warming up. This is because the heating effect of the water temperature stimulates the body's own "endocrine homeostasis" function to maintain the stability of the internal environment.

By the same principle, when the body enters water that is higher than body temperature, the body's functions will cause the subcutaneous blood vessels to dilate, blood circulation to accelerate, and the blood in the core of the body moves to the surface, thereby releasing body heat. The result is effective promotion of blood circulation.

2. Promote sweating and excrete toxins

Although healthy skin cannot compare to that of a sauna, running in the shower will also produce a lot of sweat. This is the same process as promoting blood circulation, and is also the heating effect of hot water. After the subcutaneous blood vessels expand, the body's internal heat wants to be discharged from the body, but the temperature of hot water and the city air is higher than the body temperature. As a result, the temperature of the body surface is heated by the outside, and then circulates into the body to further increase the body temperature. The body will then sweat to lower its body temperature. At this time, the sweat, along with waste in the body and garbage in the pores, will be completely discharged, thereby playing a beauty role on the skin.

3. Relax your body and mind

As your body fully enters the tub, the displacement of water causes your body to lose weight. This is the famous Archimedes' theorem.

If you immerse your body in a bathtub with the water up to your neck, the weight of your body will become about one-tenth of your body weight. If you lose the weight of your head, the weight below your neck will be only 4-5 kg. Freeing your body from the pressure of your weight can help relieve muscle tension and relax.

When soaking in hot water at about 37-39 degrees, the parasympathetic nerves in the human autonomic nervous system will play a major role. One of the functions of the parasympathetic nervous system is to put the body and mind into a resting state, so the body and mind can be relaxed.

4. Full body massage

Moderate pressure helps to relieve fatigue. Even if your bathtub does not have water massage, it can still have a massage effect. The principle is 'hydrostatic pressure'. When the hot water reaches your shoulders, the water pressure on your whole body will reach about 500 kilograms. It is a surprising fact that the waist circumference will be reduced by about 3 cm under the action of water pressure due to the abdomen without bone support. In addition, the veins close to the body surface will also be under corresponding pressure. The water pressure increases with the depth of the water. The venous blood that is easily retained in the lower body will flow back to the heart under the action of water pressure, thereby reducing the swelling of the lower body caused by standing.
