As summer approaches, the temperature gradually increases and sweating begins to increase. While sweat drives away body heat, it also takes away a lot of salt. For the elderly, due to the loss of organ function, body fluids are about 15% less than those of middle-aged and young people. Therefore, the elderly have worse thermal balance and heat resistance. If you do not regularly add water, it is prone to physiological water shortage and increased blood concentration, affect the normal blood circulation, easy to induce high blood pressure, cerebral thrombosis, myocardial infarction and other serious illnesses. Therefore, only by developing proper drinking habits can the elderly be able to spend the summer better.
Salt water and tea are the best summer weather. A lot of sweat in the summer took away sodium, vitamins, potassium, magnesium and other trace elements. If you only drink boiled water, it is difficult to quench your thirst and even cause dizziness and other unpleasant reactions. The summer tea drinking can not only add water and vitamins and other essential substances lost, but also thirst, refreshing, enhance appetite. It is best to use cool green tea, and the tea should not be too strong. Otherwise, it will easily lead to dilution of the gastric juice, which is counterproductive. Or add a small amount of salt in boiled water (500ml of water is less than 1g of salt), it can also effectively replenish water and quench thirst.
Two cups of water prevent disease in the morning. After waking up, fasting drinking water can effectively supplement the lack of moisture caused by physiological dehydration. It can also reduce the viscosity of the blood, speed up blood circulation, and promote rapid excretion of metabolic waste such as feces and urine. However, due to the sweltering summer nights, the loss of water is large, so the amount of drinking water in the morning can increase to two cups.
Avoid slamming once. If the old man is greedy for a moment and is drinking too much at one time, it will increase the burden on the heart and cause a sudden drop in blood concentration, leading to rapid heartbeat, panic, and dizziness. At the same time, the replenishment rate is too fast, moisture is difficult to be normally absorbed by the body tissue, and it cannot effectively quench thirst. It is advisable to use 100-150 ml each time. The interval is half an hour.
Take a bottle of water with you. Because of the deterioration of nervous system function, the elderly are less sensitive to water shortage in the body, and when they feel thirsty, they often have severe water shortages. Therefore, it is necessary for the elderly to carry water with them when they go out or exercise. Drink water as soon as possible after exercise to supplement the loss of water. However, the elderly are not suitable for drinking ice water, and should mainly be warm water.
