The old man was not careful when doing it and died on the spot

Swimming has a positive effect on human metabolism, temperature regulation, cardiovascular system, and respiratory system. Swimming is a suitable activity especially for those elderly people who are older, have joint pain and are unable to participate in sports such as jogging and mountain climbing. Swimming also has positive significance in slowing down cell aging and preventing and treating senile depression. However, the elderly need to pay attention to many aspects before and after swimming, otherwise, they are very likely to die on the spot.

1. You should undergo a physical examination beforehand and follow your doctor’s advice on whether you can swim.

2. When swimming, the amount of exercise should not be too much and the speed should not be too fast. The most suitable distance within 20-45 minutes is: 500-600 meters for people aged 60-70, and 300-400 meters for people over 70.

3. Choose a swimming spot. If you swim in rivers, lakes, etc., you must be aware of the water depth, whirlpools, etc. to avoid accidents.

4. Do warm-up exercises before swimming to prepare the muscles, ligaments, joints, internal organs and nervous system so that they can adapt to the needs of water activities and prevent cramps.

5. Keep your emotions stable and do not participate in swimming competitions. The elderly should relax when swimming and avoid diving or holding their breath to prevent increased lung pressure, which will increase the burden on the heart and cause accidents.

6. Don’t swim if you are too hungry or too full. Swimming when hungry can easily lead to hypoglycemia; swimming when full not only affects gastrointestinal blood supply, but can also cause acute abdomen due to increased abdominal pressure.
