When summer comes, the temperature rises gradually and sweating begins to increase. Sweat takes away the body's heat and a lot of salt. As for the elderly, due to the decline of organ function, the body fluid is less than that of young and middle-aged people 15%, so the heat balance and heat resistance of the elderly are even worse. If you don't replenish water in time, it is easy to have physiological water shortage and increase blood concentration, which will affect the normal circulation of blood and easily induce serious diseases such as hypertension, cerebral thrombosis and myocardial infarction. Therefore, only by developing correct drinking habits can the elderly spend the summer better.
Salt water and tea can cool off the heat. Sweating in summer takes away trace elements such as sodium, vitamins, potassium and magnesium. If you only drink boiled water, it is difficult to quench your thirst well, and even cause dizziness and other discomfort. Drinking tea in midsummer can not only replenish water and lost vitamins and other essential substances, but also promote fluid production to quench thirst, refresh the mind and enhance appetite. It is best to use cool green tea, and the tea should not be too strong, otherwise it is easy to dilute the gastric juice, which is counterproductive. Or adding a small amount of salt to boiling water (about 1g salt to 500ml water) can also effectively replenish water and quench thirst.
Drink two glasses of water in the morning to prevent diseases. Drinking water on an empty stomach after getting up can effectively replenish water deficiency caused by physiological dehydration, reduce blood viscosity, accelerate blood circulation, and promote the rapid discharge of metabolic wastes such as feces and urine. However, due to the sultry summer night, the water loss is large, so the amount of drinking water can be increased to two cups in the morning.
Never drink too much at a time. If the elderly crave pleasure and drink too much water at one time, it will increase the burden on the heart and make the blood concentration suddenly drop, leading to accelerated heartbeat, palpitation and dizziness. At the same time, the water supply is too fast, and it is difficult for water to be absorbed normally by body tissues for a while, which can not effectively quench thirst. It is advisable to use 100- 150ml every time with an interval of half an hour.
Take a bottle of water when you go out. Due to the deterioration of nervous system function, the elderly are less sensitive to physical water shortage. When they feel thirsty, they are often seriously short of water. Therefore, it is necessary for the elderly to carry a bottle of water with them when they go out or exercise. Drink some water as soon as possible after exercise to replenish the water lost in the body. However, the elderly are not suitable for drinking ice water, and should be mainly warm water.
