The Importance of Foot Soaking for the Elderly
There is a saying in folk tradition: "Soak your feet in hot water, it's better than eating ginseng. The rich take tonics, while the poor soak their feet." This statement is scientifically valid, as modern research has shown that there are reflex zones on the feet that correspond to various internal organs. Soaking feet can stimulate these reflex zones, promote blood circulation, regulate the endocrine system, and enhance organ functions. Foot soaking is a good health practice for both the rich and the poor. However, it is important to soak feet correctly, including the optimal water temperature and duration.
The best time to soak feet: 9 PM
The reason for choosing this time is because it is the period when the kidney meridian is relatively weak. Soaking feet at this time can increase body heat, expand blood vessels, promote blood circulation, and improve overall circulation. At the same time, it allows the nervous system, which has been stressed throughout the day, and the kidneys, which have been tired, to relax and regulate fully through foot soaking, achieving the best kidney nourishing effect and providing a comfortable feeling. It is best to avoid foot soaking when too full, too hungry, or right after a meal, as it can affect blood supply to the stomach.
The optimal water temperature for foot soaking: 42℃
Many people like to soak their feet in very hot water until it cools down completely, or even continuously add hot water and soak for one or two hours. This is incorrect. The ideal duration for foot soaking is 30 to 45 minutes, once a day or every other day. However, it is important to note that elderly people should soak their feet for a shorter period of time, as prolonged soaking can cause sweating, palpitations, and other symptoms. It is best for them to soak their feet for 20 minutes before bedtime. During foot bathing, the water should usually cover the ankles and should be stirred regularly. However, diabetics should be cautious as their skin is less sensitive to external stimuli, and excessively hot water can easily cause burns.
Foot soaking requires a certain water temperature. Generally, the water temperature should not be too hot or too cold, around 40℃ is ideal. Excessively high water temperature can not only damage the sebum film on the surface of the foot skin, causing dryness and cracking of the stratum corneum, but also cause excessive dilation of foot blood vessels, leading to insufficient blood supply to the brain, heart, and other organs. People with weak constitutions may experience dizziness and even fainting due to insufficient blood supply to the brain.
In terms of timing, it is also important to follow a certain pattern. The best time for foot soaking is between 7 and 9 PM. This is when the kidney meridian is at its weakest. Soaking feet at this time can cause the blood vessels on the soles of the feet to dilate due to the stimulation of warm water, which is beneficial for promoting blood circulation and nourishing the liver and kidneys.
