Hot-water bath: The hot-water bath carries out wiping, washing, soaking and other steps at the same time, among which the hot-spring bath is the most commonly used, and it is appropriate to take 10 ~ 20 minutes each time. If there is hot spring reaction (dizziness, chest tightness, palpitation, etc.). ), it should be a temporary break for a few days. In addition to hot spring bath therapy, the commonly used hot water bath is foot bath (that is, hot water soaking feet), and many people insist on foot bath exercise to prolong life.

Fitness effect can accelerate blood circulation and reduce the probability of thrombosis. Generally speaking, the elderly have little activity, slow blood flow and easy platelet aggregation, especially in patients with hyperlipidemia. When the blood flow is slow, it is easier to form thrombus and block small blood vessels and coronary arteries in the brain, thus inducing stroke or myocardial infarction, which is life-threatening in severe cases.

Enhance renal urinary function. Due to the accelerated blood circulation in hot water bath, the amount of blood flowing through the kidney increases correspondingly, which increases the urine production of the kidney and reduces the chance of kidney calculi formation.

Enhance digestive function. When taking a hot bath, the towel stimulates the relevant acupoints, which can enhance gastrointestinal peristalsis and increase the secretion of digestive glands, thus enhancing digestive function. This is quite beneficial to middle-aged and elderly people, because the gastrointestinal function of middle-aged and elderly people is weakened and constipation is prone to occur. Visible hot water bath is also a good way to prevent constipation.
