In winter, soaking in hot springs is a popular leisure activity for many people. Experts remind that staying in hot springs, saunas, and other enclosed environments with high temperature, high humidity, and poor ventilation for a long time may lead to heatstroke. It is best to pay attention to controlling the water temperature, time, and bathing methods, while keeping warm and relieving stress, and avoiding health hazards. We have recently received patients who have experienced dizziness, fatigue, and even coma due to prolonged soaking in hot springs. After diagnosis, these patients have been diagnosed with heat stroke. ”Sun Zhijun, chief physician of the Department of Cardiovascular Medicine at Shengjing Hospital affiliated with China Medical University, said, "Heat stroke, also known as severe heatstroke, is a condition where the body cannot dissipate heat in a high temperature and humidity environment. If the internal temperature of the body rises above 40 degrees Celsius in a short period of time, it may damage multiple organs such as the brain." Sun Zhijun reminded that when soaking in hot springs, the water temperature should not be too high, preferably controlled between 38-40 degrees Celsius; It is advisable to soak for 10-15 minutes at a time, and slow down when getting up to avoid dizziness or falling due to changes in body position; Properly replenish water, avoid drinking and smoking in the hot spring pool, and reduce the risk of accidents. If you feel chest tightness, palpitations, dizziness, or cold sweat, don't force yourself. You should immediately leave the pool and rest in a well ventilated place. If the symptoms don't improve, you must seek medical attention in a timely manner, "said Sun Zhijun. Wu Yan, chief physician of the Department of Dermatology at Shengjing Hospital affiliated with China Medical University, reminds us to pay attention to protecting the skin and avoiding damaging the skin barrier when taking hot baths and soaking in hot springs in winter. The water temperature should not be too high to avoid excessive removal of the natural sebum film on the surface of the skin; prolonged exposure to a humid and hot environment can lead to excessive hydration of the stratum corneum, further weakening the skin barrier function and exacerbating dryness and itching, "said Wu Yan. Wu Yan suggests that after drying the body, apply moisturizing cream immediately when there is still a trace of moisture on the surface of the skin. It is advisable to choose products containing ingredients such as ceramide, squalane, hyaluronic acid, etc. Patients with sensitive skin and inflammatory skin diseases such as eczema should be cautious, as high temperatures may worsen skin damage and minerals in hot springs may also cause irritation. Ji Hong, chief physician of the Department of Traditional Chinese Medicine at Shengjing Hospital affiliated with China Medical University, introduced that scientific bathing can help with winter Tibetan health preservation, but the principle of "moderate, timely, and suitable for people" should be followed: immediately wipe dry and keep warm after washing, and avoid touching cold water with wind; Soak until slightly sweaty; It is not suitable to take a bath after meals, when hungry, tired, or after drinking alcohol; The elderly, infants, pregnant women and people with diabetes or cardiovascular and cerebrovascular diseases have relatively poor thermoregulation ability and higher risk; After taking a bath, you can sit for a while and drink warm ginger and red date tea or diluted salt water to replenish body fluids.
