What problems should the elderly pay attention to when swimming?

Persisting in long-term swimming exercise is helpful to treat cardiovascular diseases in the elderly. Swimming can also restore the strength of the respiratory muscles of the elderly, improve the depth of breathing, increase vital capacity, and help prevent respiratory diseases; It can improve the body temperature regulation function and enhance the adaptability to climate change; Can improve blood circulation, improve metabolic function, enhance muscle strength and joint flexibility. Swimming also has a certain therapeutic effect on the elderly suffering from lumbar muscle strain and chronic arthritis.

Although swimming has many benefits for the elderly, we should pay attention to quantity and degree in everything and should not overdo it. Old people should pay attention to the following problems when swimming.

(l) Because swimming consumes a lot of physical strength, elderly people with severe hypertension, heart disease, active tuberculosis and viral hepatitis should not participate in swimming activities. In addition, the elderly exercise slowly and move slowly when swimming, so it is necessary to gradually extend the swimming time and distance.

(2) Old people have fragile blood vessels and high blood pressure. When swimming, the water temperature should be moderate, not too cold. Otherwise, low water temperature will lead to sudden contraction of blood vessels, sharp rise of blood pressure, increasing the burden on the heart, which is not conducive to safety.

(3) Be prepared before swimming. Proper warm-up activities can not only activate the stiff muscles, ligaments and joints of the elderly, but also improve the excitability of nerves and enhance the adaptability of cardiovascular system and respiratory system.

(4) The elderly have poor thermoregulation function, so the time spent in water should not be too long, and enough is enough to prevent catching cold.

(5) Don't hold your breath when swimming, so as not to increase the pressure on the lungs and increase the burden on the heart, which is not good for your health.
