Beware of heat shock ！.

Heat shock is a health hazard caused by fluctuations in blood pressure brought on by sudden changes in temperature.
For example, …
When bathing on a cold winter day, one goes from an air-conditioned room to a cold changing room and then to a hot bathtub. At this time, our body tries to cope with the sudden change in temperature by lowering and raising our blood pressure, which in turn is a burden to our body.

It is important to note that this can lead not only to temporary fainting but also to myocardial infarction or stroke.

How to prevent heat shock ？
1 ） Keep the temperature difference between the room and the changing room within 5°C ！
If your changing room or bathroom has a heating function, by all means use it. If there is no heating function, you can leave the bathtub lid off or leave the shower on for a while to fill the bathroom with steam to warm the inside of the bathroom.

2 ） Keep the bathtub temperature below 41°C ！
Soaking in 41°C water for 10 minutes is recommended. If the temperature is too high, you will not be able to soak for long and only the surface of your body will be warmed. Also, prolonged soaking in hot water can cause dehydration.

3 ） It is dangerous to suddenly get into a bathtub ！
Suddenly getting into a bathtub can cause a sudden change in blood pressure.

4 ） It is dangerous to stand up suddenly ！
It is very dangerous to stand up suddenly from the bathtub. Blood vessels dilate as the body warms up, and standing up abruptly may cause dizziness. Hold on to the handrail and stand up slowly.

5 ） After bathing, wipe the moisture from your body in the bathroom ！
The bathroom is warm after bathing, so it is difficult to cool your body. To some extent, wiping off the moisture with a bath towel before going out to the changing room will reduce the effect of the difference in room temperature.

6 ） Stay hydrated ！
Sweating while bathing and losing water in the body increases the risk of myocardial infarction and stroke. Drink water before and after bathing.

7 ） Others
（ 1 ） Complete bathing before sunset when temperatures are relatively high
（ 2 ） Avoid bathing immediately after eating

. Please make it a habit to take a bath ！
