1, step by step.
Because the water temperature is 10 degrees lower than the body temperature, if you swim for a long time, your body will get cold. This is a signal that the body loses more heat than it generates. Now, you should go ashore to warm up at once. Otherwise, the continuous drop of body temperature will lower the core temperature of the body, leading to serious symptoms, such as arrhythmia and insanity, loss of motivation, and even drowning death. Therefore, the swimming time should be from short to long, and the swimming time of one day or one day should not exceed 2-3 hours, which needs to be divided into several sections.
2. Eat moderately.
Swimming is effective to lose weight, because the water temperature is low, and the body consumes more calories than land exercise, which is beneficial to the consumption of energy and fat. However, it should be noted that after swimming, you will feel hungry and your appetite will increase. If you eat too much, you can't lose weight.
3. Swimming also needs to control calorie intake.
If we swim to lose weight, but we are hungry after exercise, we will eat a lot, which greatly reduces the effect of swimming to lose weight. Therefore, while swimming to lose weight, we should also pay attention to controlling calorie intake. Only in this way, finally, can you get a good exercise effect.
4. Remember to replenish water.
Swimming for 2-3 hours can reduce 1-2 kg body weight, most of which is water and a little fat. Therefore, 500- 1000 ml of liquid should be supplemented during intermittent swimming to maintain water and acid-base balance in the body.
5. Warm-up exercise before swimming.
Although swimming can reduce the burden on the body, if you swim too fast, too hard and too hard, you may get hurt. To avoid injury while swimming, remember to warm up before entering the water.
