Come home in cold weather, take a bath in half an hour!

When it was cold and freezing days, many people returned home and wanted to take a hot bath immediately to warm up their bodies, but they didn't know that it was very dangerous. Middle-aged and elderly people have poor blood vessel elasticity, and their body's regulatory function has declined. For patients with cardiovascular and cerebrovascular diseases, taking a hot bath directly after returning home from the cold outdoors can easily cause a heart attack.

It is best to take a bath safely in winter and people with poor cardiovascular conditions should follow several principles:

1. When you come home from the outside, do not go directly to the bathroom to take a shower. You should rest for 30 minutes to 1 hour to let your body gradually warm up before washing.

2. Some people take a bath in winter and like to adjust the water temperature higher. The bath water temperature is equivalent to body temperature, preferably not more than 40°C. Turn on the shower first, let the hot water vapor raise the temperature of the bathroom, and then start bathing after the bathroom has warmed up. If the weather is particularly cold, or your physique is poor, you can also turn on the electric heater, bath heater, etc. before taking a bath.

1. The temperature in the bathroom is high, and the temperature in the bathroom drops sharply after taking a shower, which can easily induce myocardial infarction. Ma Genshan said that a sudden cold stimulus can cause sudden contraction of coronary arteries, acute myocardial ischemia and hypoxia, and in severe cases, angina pectoris and even myocardial infarction can be induced. After taking a bath, be sure to wipe off the water on your body, put on your pajamas, and wait until your body gradually adapts to the outside temperature before going out of the bathroom.

2. The bathing time should be controlled at about 10-15 minutes, so as not to stay in a closed and airtight environment for a long time, resulting in hypoxia and insufficient blood supply. The bathroom must have ventilation equipment, and a ventilator can be used to promote air circulation.
