First, keep calm and don't panic. Second, actively call for help and see if anyone nearby calls for help. Third, be sure to catch floating objects or solid objects.

First, "jellyfish drift" maintains physical strength

When waiting for rescue, you can maintain your physical strength through the posture of "jellyfish floating". Shrink your head, put your knees in your hands, put your knees against your chest, and float quietly like a jellyfish. When breathing, press the water down with your hands, pinch the water back and forth with your feet, raise your head by reaction, inhale instantly, and continue to float. Hu Bei said that this can last for a long time in the water. If you can drift, the self-help effect is better.

Second, how to deal with underwater cramps in an emergency?

If you accidentally fall into the water, you may cramp if you are too tired and physically exhausted, or if you are nervous or nervous and have uncoordinated swimming movements. Hu Bei said that the main parts of underwater cramps are calves and thighs, and sometimes fingers, toes and other parts also occur. Don't panic if you suddenly have a cramp underwater. While seeking help, you can take the following measures to deal with cramps:

1, if the finger cramps, you can make a fist with your hand, then open it hard and do it several times quickly until the cramps are eliminated;

2. If the calf or toe cramps, first take a breath and float on the water, hold the toe of the cramped limb with the hand on the opposite side of the cramped limb, and pull it hard toward the body. At the same time, press the knee of the cramped limb with the palm on the same side to help the cramped leg straighten;

3. If the thigh cramps, it can also be solved by stretching the cramped muscles.
