When you go into the water, you should wash your face, head, chest, back and four livers first, so that the body can adapt to the cold stimulation, and then swim.
When swimming, painful convulsions (commonly known as cramps) are often encountered. When cramps occur, keep calm and swim ashore as soon as possible. Wait until the body returns to normal. Methods to correct the cramp: finger cramp can be clenched into a fist, and then open the hand forcefully; toe cramp, to quickly bend the leg, pull the toes open, straighten; calf cramps can first take a breath, float on the water, bend the thigh to make it at a right angle with the upper body, and bend the knee joint, so that the lower leg sticks to the thigh and vibrates back and forth for several times After the leg straight forward, repeated movement, until it returned to normal. If the cramp is severe or persistent, do not continue swimming
