When you soak your feet in hot water, the blood vessels on your feet will expand and the skin on your feet will turn red. This is because soaking feet with hot water accelerates the blood circulation of feet. Let more blood flow to the peripheral blood vessels of the lower limbs, and then the cerebral blood flow decreases, which makes people feel sleepy and the brain feels comfortable and relaxed, thus speeding up sleep and deepening sleep.
Nowadays, many people who work in cities have weak spleen and stomach, insomnia and headaches due to the fast pace of life and heavy work pressure, which can easily affect their normal work and life. Therefore, it is a very good choice to soak your feet after dinner at night. Put your feet in hot water for a minute or two and you will feel relaxed and get rid of fatigue quickly.
Soaking feet can also strengthen the body, because there are many acupuncture points on the feet. Often soaking feet can stimulate plantar acupoints, which not only enhances blood circulation, but also strengthens the functions of various organs of the body. However, the foot soaking time should not be too long. If the foot soaking time is too long, it will easily lead to excessive local blood circulation in the foot for a long time, thus causing cardiovascular overload. Usually about half an hour, the water temperature is about 40 degrees.
