Drowning self-rescue first of all to remain calm, do not struggle indiscriminately, remove the body’s restraints, take the position of the backstroke, waiting for rescue. 1. First of all, be calm, do not tread water or hands and feet move, otherwise it will make the limbs are entangled more difficult to free, or in the mud deeper and deeper, and will consume physical strength, and easy to choke. 2. Slowly return to the original way by backstroke (legs straight, paddling backwards with palms). Or lie flat on the surface of the water, spread your legs apart and use your hands to free yourself. 3. If you are entangled by water plants, you can try to kick the water plants away, or like taking off socks to run the water plants down from your hands and feet. If you can’t get rid of it by yourself, you should call for help in time. 4. After getting rid of the water plants, gently kick your legs and swim, and leave the place where the water plants are overgrown as soon as possible.
