How can the elderly stay healthier without replenishing water?

　　first, elderly Take a rest after exercising and taking a bath, because at this time, the heart of the elderly is beating strongly. If you drink water, it will increase the burden on the heart, especially the elderly with heart disease.

　　When the heart beat feels slightly stable, the elderly can start to drink warm water slowly, in small sips, and multiple times. It is best to keep the frequency of each small sip close to the heart rate. In this way, the heart can receive and promote the absorption of drinking water regularly and smoothly.

　　After sweating at a high temperature, you should not drink a lot of water at once, otherwise you will easily experience palpitation, shortness of breath, sweating, etc.

　　Excessive sweating caused by high temperature will cause the body to lose a lot of salt. If you drink a lot of water, it will dilute the salt in the blood and increase sweating, further aggravating the "thirst" feeling.

　　When sweating a lot, the blood vessels in the human gastrointestinal tract are in a contracted state and have poor absorption capacity. Drinking a large amount of water is easy to accumulate in the gastrointestinal tract, making the elderly feel bloated and causing indigestion.

　　Correct approach: It is best for the elderly to gargle with water to moisten the mouth and throat, and then drink 50 ml to 100 ml of light salt water (add 2 grams of salt to 100 ml of water)； After resting for 30 minutes, add boiled water at room temperature (about 25 degrees Celsius).
