Extreme high temperatures can be macabre. They may hurt or even kill people. As summer arrives, how can we stay safe in very hot weather? Doctors give us some advice on that.

First, be prepared:

▲Do not use a fan as your main cooling device(设备). It creates airflow(气流) and might keep you comfortable, but it does not reduce your body temperature.

▲Stay in the air conditioning. If you are outside, search for cool places in the community you can go, such as libraries, malls or cooling centers.

During extreme heat, remember:

▲Drink plenty of water even if you don’t feel thirsty.

▲You should reduce outdoor activities as much as possible, but if you do go out, wear loose and light-colored clothing.

▲A cool shower or bath can help you cool down.

▲Watch for the signs of heat stroke(中暑). These can include red, hot and dry skin with no sweat. Also looks for a rapid, strong pulse and dizziness.

What should you do if you see signs of heat stroke? Here’s advice:

If you see any of these signs in anyone, you may be dealing with a life-threatening emergency—you should get medical attention as soon as possible. While waiting for the doctors, try to cool the person down.

▲Get the person out of the sun.

▲Lower his/her body temperature by putting him/her in a shower with cool water. You can also wrap(包裹) the person in a wet sheet(床单).
