The incident occurred on 12/1 in Zhengzhou city. Local media reported that a boy lost consciousness and fell into a coma after soaking in a hot tub with water temperature close to 40 degrees Celsius. He was rushed to the emergency room in critical condition and diagnosed with intracranial hemorrhage, a type of stroke causing bleeding in the brain.

The direct cause was identified as prolonged exposure to high temperatures, which led to excessive dilation of blood vessels. This, coupled with dehydration, caused the blood to thicken, impeding circulation and ultimately resulting in a vessel rupture.

The treating doctor explained that children and teenagers have underdeveloped vascular systems and thermoregulation. Exposure to environments above 40 degrees Celsius makes this age group susceptible to low blood pressure, oxygen deprivation, and heat stroke. The risk is particularly high in enclosed, poorly ventilated bathrooms, which can place significant stress on the cardiovascular system and brain if the body is not rehydrated promptly.

Adults, not just children, face risks from prolonged exposure to overly hot water. High temperatures redirect blood flow to the skin's surface, potentially depriving internal organs of adequate blood supply. Individuals with pre-existing conditions like heart disease, high blood pressure, or diabetes are vulnerable to arrhythmias, angina, and even stroke. Moreover, men who regularly soak in water above 40 degrees Celsius may experience reduced sperm production, which increases the risk of infertility.

Experts recommend that children's bath water remain below 38 degrees Celsius, with soaking times not exceeding 10 minutes, and always under adult supervision. For adults, the ideal temperature ranges from 37 to 40 degrees Celsius for a maximum of 15 minutes.

To ensure safety, avoid bathing when overly hungry or full. Keep the bathroom well-ventilated and drink small sips of warm water to aid circulation. If symptoms like severe headache, vomiting, confusion, limb weakness, or seizures appear after bathing, lay the patient flat, turn their head to one side to prevent choking, and call for emergency medical assistance immediately.
