March 22 is World Water Day. How did World Water Day come about? What little knowledge is there about “water”? Let’s find out together!
Origin of World Water Day:
Water is the source of life and one of the most precious resources in the world. With the increasing demand for water, in order to draw the world’s attention to water issues, on January 18, 1993, the 47th United Nations General Assembly, in accordance with the recommendations in the “21st Century Action Agenda” formulated by the United Nations Conference on Environment and Development, decided to Since that year, March 22 every year has been designated as “World Water Day”.
After the promulgation of the “Water Law of the People’s Republic of China” in 1988, the Ministry of Water Resources designated July 1 to 7 each year as “China Water Week”. Considering that the theme and content of World Water Day and China Water Week are basically the same, so from Since 1994, the time of “China Water Week” has been changed to March 22 to 28 every year. The overlapping of time makes the publicity activities more prominent the theme of “World Water Day”.
Daily water saving tips:
1. Develop a good habit of turning off the faucet at will.
2. When cleaning cooking utensils and tableware, if the oil is too heavy, you can wipe off the oil with paper first, and then rinse.
3. Use water for washing rice, cooking noodle soup, and overnight tea to clean tableware and chopsticks, which can remove oil and save water consumption and the pollution of detergent.
4. When washing vegetables, do not wash them directly under the faucet, but put them in a water container as much as possible, and adjust the cleaning sequence. For example, wash leafy and fruit vegetables first, then root vegetables; peel and puree vegetables with skins, and then wash them.
5. Do not use long-flow thawing to freeze ingredients.
6. When going out or in meetings, bring your own water cup or small-capacity bottled water to reduce the waste of remaining bottled water.
7. Do not waste the leftover tea and mineral water for watering the flowers.
8. Do not pour out the remaining water in the pot before filling it, it can be collected with other circulating water for reuse.
9. If conditions permit, try to use a new type of water-saving toilet.
10. Collect laundry, vegetables, bath water, etc. to flush the toilet.
11. Do not throw rubbish in rivers and lakes, do not litter waste batteries, to prevent pollution of natural water resources.
12. Teach children to conserve water and encourage them not to play water-consuming games.
Drinking water university
1. Why do people need to replenish water every day?
Water is the source of life, the main component of the human body, and an essential nutrient for the human body. Water in newborns accounts for 80% of body weight, infants and young children account for 70% of body weight, and adults account for about 50%-60%.
The role of water is mainly manifested in the following four aspects: First, it participates in human metabolism; second, it participates in nutrient transport and waste excretion; third, it constitutes an important component of blood and cell fluid; fourth, it regulates body temperature.
2. How much water do adults need per day?
Water requirements are mainly affected by factors such as age, ambient temperature, and physical activity. Generally speaking, healthy adults need about 2500mL of water per day. Lightly physically active adults living in mild climates drink a minimum of 1200 mL (about 6 cups) of water per day. Under the conditions of high temperature or strong physical labor, drinking water should be increased appropriately. Insufficient or too much drinking water can bring harm to human health.
3. When is the best time to drink water?
Drinking time should be allocated at any time of the day, and water should be taken in small amounts and several times. Be proactive and don’t drink water when you feel thirsty.
The best choice for drinking water is boiled water. About 200mL each time (1 cup). The water you drink on an empty stomach only stays in the stomach for 2-3 minutes, and soon enters the small intestine, where it is absorbed into the blood, and can be replenished to the whole body in about 1 hour. When the water in the body reaches a balance, it can ensure the sufficient secretion of digestive juice during meals, increase appetite and help digestion. Drinking a lot of water at one time will increase the burden on the gastrointestinal tract and dilute the gastric juice, which not only reduces the bactericidal effect of gastric acid, but also hinders the digestion of food.
After getting up in the morning, you can drink a glass of water on an empty stomach, because the hidden sweat and urine secretion during sleep lose a lot of water. Although there is no thirst after getting up, the blood in the body will still be sticky due to lack of water. Drinking a glass of water reduces blood viscosity and increases circulating blood volume. You can also drink a glass of water before going to bed. Helps prevent the increase of blood viscosity at night.
Due to the accelerated loss of water in the body during exercise, if it is not replenished in time, it can cause water shortage. When the intensity of exercise is high, attention should be paid to the simultaneous supplement of water and minerals during exercise, and sufficient drinking water should be added in time as needed after exercise.
