Cool boiled water is the best drink for the elderly!
Nowadays, people have long been accustomed to the hygiene and convenience of water dispensers, and cool boiled water seems to be fading further from daily life. But did you know, cool boiled water is the best drink for seniors.
Cool boiled water refers to water that has been boiled and then naturally cooled to 20°C—25°C. Research has found that after boiled water cools naturally, the chlorine content in the water is 50% lower than in regular water.
Cool boiled water is very beneficial to human health. It not only moistens the throat, refreshes the mind, prevents bad breath and constipation, but also has a certain therapeutic effect on pharyngitis. A glass of cool boiled water in the morning on an empty stomach can cleanse the stomach, detoxify, and promote longevity.
For the elderly, cool boiled water is the best drink. Pour boiled tap water into a clean, covered container and let it cool to 20—25°C before drinking. Drinking a glass of cool boiled water on an empty stomach after waking up every day not only prevents colds but also enhances the liver's detoxification ability and the digestive tract's excretion ability, promotes metabolism, and helps lower blood pressure and prevent myocardial infarction.
The water temperature should be adjusted according to the specific situation; drink warm water in the winter to warm the stomach, and slightly cooler water in the summer to relieve the heat. Cool boiled water should not be stored for too long, preferably not exceeding 24 hours. If left for too long, the water will not only be contaminated by bacteria in the air but will also lose its "activity" as gases dissolve back into it. The source of the water for cool boiled water must be clean. Water that has been repeatedly boiled, leftover water from steamed food, or water that has been boiled for a long time is not suitable for drinking.
Although cool boiled water is good, it should be consumed in moderation. Generally, drinking 1.5—2 liters of water per day is appropriate. Drinking too little water is not good, but excessive water intake can also lead to poisoning. For people who are very active and sweat a lot, they lose electrolytes from their bodies. Drinking a large amount of water immediately can lead to muscle cramps, etc. Therefore, after exercise, one can drink a little salted boiled water.
