Traditional Chinese medicine emphasizes adapting to nature for health preservation, which has the characteristics of "spring birth, summer growth, autumn harvest, and winter storage". In summer, the human body enters a critical period of "growth and development", during which metabolism increases and skin pores open due to heat, leaving opportunities for pathogenic and evil qi to take advantage of. Soaking your feet appropriately at this time can help eliminate heat and dampness, increase appetite, and better stimulate meridians and invigorate the functions of the body's organs. But there are also some precautions for soaking feet. It is also possible to experience numbness in both hands at night. For patients with arteriosclerosis obliterans or diabetes feet, especially those with poor limb blood supply, the foot soaking time should be controlled within 20 minutes. Soak until slightly sweaty. Some people like to soak their feet in hot water, feeling comfortable sweating all over the body, but after sweating, the pores of the skin will open, making it easy to catch a cold. So the water temperature for soaking feet should not be too high, at 38-40 degrees Celsius, as long as the whole body feels warm and slightly sweaty. After soaking your feet, wipe them dry immediately. If the feet are not wiped dry in time after soaking, dampness and coldness can easily enter the body from the feet. After soaking your feet, you should immediately dry them with a dry towel and apply moisturizer if necessary. It is best for weak or sick people to wear a pair of socks. (New Society)
