What are the benefits and drawbacks of taking a hot shower

Taking a hot shower can promote blood circulation and relieve fatigue, but excessive water temperature or prolonged time may damage the skin barrier and increase the burden on the heart. Reasonable control of water temperature and duration can balance comfort and health.

Warm stimulation during hot water bathing can cause surface capillaries to dilate, accelerate blood circulation, help relieve muscle tension and joint stiffness, and is particularly suitable for use after exercise or in cold seasons. Appropriate water temperature can also help open pores and promote the elimination of metabolic waste, which is helpful for improving sleep quality. Some people, such as those with wind dampness, can alleviate pain symptoms by soaking in hot water, but it is important to note that the water level should not exceed the height of the heart. When the water temperature exceeds 45 degrees and continuous rinsing lasts for more than 15 minutes, it may damage the natural oil layer on the surface of the skin, causing dryness, itching, and even triggering dermatitis. Cardiovascular disease patients who are exposed to hot water for a long time are prone to discomfort such as chest tightness and dizziness, and elderly people need to be more alert to orthostatic hypotension caused by rapid vasodilation of blood vessels. Children with delicate skin should strictly control the water temperature below 38 degrees Celsius, while pregnant women should avoid prolonged exposure to overheated water flow in the abdomen.

It is recommended to maintain the bath water temperature between 38-42 degrees Celsius for 10-15 minutes, and apply moisturizing products promptly after bathing. In winter, the room temperature can be appropriately increased to reduce temperature difference stimulation, and high-risk cardiovascular individuals can choose warm water for rapid flushing. Pay attention to whether the skin turns red and hot after taking a shower, and if there are persistent palpitations or dizziness, stop immediately and consult for reasonable adjustment of bathing methods to fully utilize the health benefits of hot water baths.
