With the arrival of summer, several Southeast Asian countries are facing a wave of intense heat. Meteorologists predict that this year could see a once-in-60-years high-temperature weather, with maximum temperatures expected to exceed 45℃. In the face of such extreme weather, we need to take appropriate precautionary measures to ensure our health and safety.

First, it is crucial to maintain adequate hydration in high temperatures. However, the way of drinking water also needs attention. It is recommended to drink room temperature water slowly, avoiding large amounts of ice water. This is because a sudden drop in body temperature may irritate the blood vessels, leading to discomfort or even more serious health issues.

Secondly, when entering indoors from a hot environment, do not immediately wash your body with cold water. It is very important to give your body some time to adapt to the temperature change, and it is recommended to wait at least 30 minutes before taking a shower or bath. This can help avoid adverse reactions caused by extreme fluctuations in body temperature.

Moreover, during extremely high temperatures, even seemingly simple cooling methods may pose unexpected risks. Reports have indicated that some individuals who immediately soaked their feet in cold water after being exposed to high heat fainted; others who took a cold shower in a high-temperature environment experienced muscle stiffness and even triggered a stroke. These cases remind us to be particularly cautious when dealing with discomfort caused by high temperatures.

In summary, during the hot summer, we should:
1. Maintain adequate hydration but avoid drinking excessively cold beverages.
2. After entering an indoor environment from a high-temperature environment, give your body some time to adapt before engaging in cooling activities such as taking a shower.
3. Avoid extreme cooling methods, such as rinsing the body with cold water.

By following these tips, we can have a safer and more comfortable summer. Let's pay attention to and share this important health information to ensure everyone can safely get through the upcoming hot weather.
