Little Secrets in Drinking Water

70% of the Earth's surface and 70% of the human body are composed of water. This astonishing coincidence fully demonstrates how important water is to humanity. But in daily life, you may rack your brains for a meal, but you won't bother with drinking a glass of water. Most people think that drinking water is the simplest thing to do. Picking up a cup and "gurgling" a cup of water is enough, isn't it? In fact, the knowledge of drinking water goes far beyond these. Below is a small secret about drinking water that is unknown to everyone.

1. Detoxification: A glass of water in the morning. Many people know that drinking a glass of water in the morning is beneficial to the body. After a night of metabolism, the human body needs external help to eliminate waste, and water is the best "cleaning agent". At this point, the cells are like a dry sponge, capturing the water they drink and excreting it in about 40 minutes. This is an important detoxification process. Diluted salt water, honey water, and plain boiled water are all very suitable for drinking in the morning. Don't drink water that is too cold or too hot in the morning, and the temperature should be around 40 degrees Celsius.
2. Irritation: Drink plenty of water. The endorphins produced by the brain are called "pleasure hormones," while adrenaline is commonly referred to as "pain hormones.". When a person is in pain and irritability, adrenaline will soar, but like other toxins, it can also be excreted from the body. One method is to drink plenty of water. If assisted with physical labor, adrenaline will be excreted along with sweat, or if you cry a lot, it will also be excreted with tears.
3. Stress relief: Drink a glass of water before making a decision. A study by the University of East London in the UK has found that drinking a glass of water before exams can improve cognitive abilities and lead to better performance in exams. For office workers, drinking a glass of water before feeling too stressed or needing to make a decision can help their minds become clearer.
4. Not thirsty: You also need to drink water. A survey shows that one-third of adults drink less than 6 cups of water per day. Office workers are busy with work and often don't even have time to take a sip of water for half a day. The American website "Water Health" points out that when people feel thirsty, their bodies have already lost at least 1% of their water. Therefore, office workers should develop good drinking and urination habits, drinking water every hour and urinating every 2-3 hours.
5. Before bedtime: Take two sips of water. When a person is asleep, due to the loss of water in the body, the water in the blood decreases and the viscosity of the blood increases. Drinking some water before bedtime can reduce blood viscosity and lower the risk of cerebral thrombosis for elderly people. In addition, during the dry autumn and winter seasons, water can also moisturize the respiratory tract and help people fall asleep better. But it should be noted that drinking too much water before bedtime is not advisable. Elderly people have a habit of waking up at night, and if poor sleep is caused by drinking water, the benefits outweigh the losses.
6. After taking a shower: Drink water slowly. Many people feel thirsty after taking a shower and will pick up their cups and drink them all in one gulp. Due to the weaker physical condition of the elderly, their heart capacity is not as strong as that of young people. Especially after taking a hot bath, the body's heated blood vessels expand, blood flow increases, and the heart beats faster than usual. Drinking water should be especially careful. It's best to take a small sip and drink a cup of warm water slowly, otherwise it can easily increase the burden on the heart.
7. After exercise: Drink with your heart beating. Elderly people should not drink a large amount of water at once after exercising. Because at this point, the gastrointestinal blood vessels are in a contracted state and require a recovery process. If you drink a large amount of water immediately, the accumulation of water in the gastrointestinal tract can cause bloating and affect digestion. It's best to wait for a few minutes until the heart beats slightly more steadily, then continue to drink some warm water in small sips. When drinking water, try to maintain a steady pace, and the frequency of drinking water should be close to the heart rate. Then, drink it intermittently and in multiple doses. In this way, the heart can absorb the water entering the body in a regular and stable manner.
8. Cold: Drink more water. Drinking more water or pure fruit juice when catching a cold is very helpful for disease recovery, as it helps flush away mucus from the respiratory tract and makes people feel comfortable breathing. In addition, if you have a fever, the human body needs to cool down in response to its self-protection function. At this time, there will be signs of accelerated metabolism such as sweating, shortness of breath, and increased evaporation of water from the skin, requiring a large amount of water supplementation. Drinking more water not only promotes sweating and urination, but also helps regulate body temperature and promote the rapid elimination of bacteria in the body.
9. Constipation: Drink plenty of water. There are two simple causes of constipation: one is the presence of feces and a lack of water in the body; Secondly, organs such as the intestines have lost their excretion capacity. Drink water in large gulps and swallow quickly, so that the water can quickly reach the intestines, stimulate intestinal peristalsis, and promote defecation. Traditional Chinese medicine believes that one of the reasons for constipation is the lack of body fluids in the human body. Drinking large amounts of water can quickly replenish body fluids, stimulate intestinal peristalsis, and promote bowel movements. Chen Xiafei, the director of the nutrition department at Shanghai East China Hospital, suggests that people with constipation should supplement their diet with fiber while replenishing water for better results. Therefore, it is best to drink a glass of high fiber vegetable juice every day.
10. Obesity: Drink a glass of water before and after meals. Many chemical reactions in the human body are carried out in water. Having enough water is essential to ensure the normal functioning of the body's metabolic mechanisms. For obese people, drinking a small glass of water about half an hour before meals can increase their sense of fullness; Half an hour after a meal, drink another small glass of water to strengthen your digestive function and help maintain your figure.
11. Vomiting: Drink some diluted salt water. Vomiting is a manifestation of self-protection in the human body after consuming unclean food. To avoid dehydration symptoms caused by severe vomiting or diarrhea, it is advisable to drink some diluted salt water to replenish physical strength and alleviate weakness.
