What are the benefits of drinking more water

In life, everyone knows that water is the source of life, and drinking water regularly has many benefits to the human body. So many people think that the more water you drink, the healthier your body will be. In fact, this is not the case. Although water has many benefits to our body, everything has two sides, and the more is not necessarily better, especially drinking water. There are also some rules for drinking water. So what are the benefits of drinking more water?

Disadvantages of drinking lots of water:

It is not advisable to drink too much water half an hour after a meal

It is best not to drink a lot of water half an hour after a meal, so as not to dilute the gastric juice, dilute the gastric acid, and damage the digestive function. Drinking some water after a meal or some soup during a meal can mix the digestive juices with the food, which is good for digestion and absorption. However, some people drink a lot of water after meals, which is unscientific.

After people eat, food takes up most of the space in the gastrointestinal tract. Drinking a lot of water will fill up your stomach and make you feel bloated and painful. In addition, if a person eats too much and drinks a lot of water, the food in the stomach will be heavy, which may cause the stomach to ptosis or expansion.

Drinking too much water after a meal will dilute the concentration of gastric juice and affect the digestion and absorption of food. The human stomach can secrete about 1.5 to 2.5 liters of gastric juice every day, which contains about 0.4% to 0.5% gastric acid. The chemical composition of gastric acid is hydrochloric acid. Hydrochloric acid can dissolve proteins, digest foods containing calcium and iron, and kill bacteria that enter the stomach with food. If you drink plenty of water after meals. Dilutes gastric juice. The ability of hydrochloric acid to digest food is weakened, and its bactericidal power is also weakened. Therefore, it is best not to drink water or drink less water after a meal.

In general, only scientific water replenishment can better promote physical health. Therefore, for anyone in real life, don’t drink too much water every day. You can choose the water you need according to your body’s needs. Only in this way can water truly become the source of life and better promote physical health.

What are the precautions for drinking water for the elderly?

1. Do not drink water that has been stored for too long.

Drinking water that has been stored for too long for a long time can easily make people sick. This is because bacteria will grow and multiply in water that has been stored for more than three days, producing large amounts of nitrite, a carcinogen. When a large amount of nitrite enters the human body, it can cause poisoning, causing the red blood cells in the blood to lose their oxygen-carrying function, resulting in tissue hypoxia, and symptoms such as skin cyanosis, headache, nausea, vomiting, chest tightness, and palpitations. In severe cases, it can even be fatal.

2. It is better to drink light tea

Warm and light tea can make people feel refreshed and have sharp ears and eyes. Cold tea has the disadvantages of causing coldness and phlegm. When there is nothing in the stomach, the nature of tea goes straight into the internal organs and attacks the spleen and stomach with coldness, so it is not advisable to drink tea on an empty stomach.

3. Binge drinking is not advisable

Some elderly people like to drink heavily after physical exercise or housework. This "rapid drinking" method of drinking water will suddenly increase the burden on the heart, cause a sudden drop in blood concentration, lead to rapid heartbeat, panic, dizziness, and is more likely to cause danger to patients with heart disease. It will also suddenly dilute the gastric juice, damage the gastric mucosa, and affect appetite and gastric digestion function. At the same time, if the water is replenished too quickly, the water will not be normally absorbed by the body tissues for a while, which will not only fail to quench thirst effectively, but also cause excessive sweating and lead to abnormal heart rhythm and blood pressure.

4. Do not drink a lot of water before, during, or after meals.

When elderly people chew food with their teeth, their mouths secrete saliva which mixes with food fragments. Saliva helps digest food. After food enters the stomach, gastric juice and stomach acid play a greater digestive role, and the nutrients are absorbed by the human body. If you drink a lot of water during these three times, it will obviously dilute the saliva and gastric juice, weaken the digestion of food, cause indigestion, and affect the health of the body.

Long-term drinking will lead to calcium deficiency. Other beverages have a diuretic effect. Drinking them in the early morning will not only fail to effectively replenish the body's lack of water, but will also increase the body's demand for water, causing dehydration.

3. Temperature requirements for drinking water for the elderly

When the elderly get up in the morning to drink water, it is best to drink boiled water at room temperature; when it is cold, they can drink warm boiled water to reduce irritation to the gastrointestinal tract. When you let boiled water dry the night before, be sure to cover it. Because boiled water will lose its activity if exposed to the air for too long.
