Nowadays, with the continuous improvement of people’s living standards, everyone is paying more and more attention to health preservation. Now everyone has the concept that drinking more plain water is good for health. So, when is it good to drink plain water? Let’s discuss this issue below. We all know that people should drink eight glasses of water a day and should not wait until they feel thirsty to remember to drink water.

Because when you feel thirsty, it means that the body is severely dehydrated and the balance of water in the body has been lost. Therefore, it is necessary to replenish water regularly, usually drinking a glass of plain water on an empty stomach before each of the three meals, because the digestion of food depends on the digestive juices secreted by the digestive organs. The total amount of digestive juices secreted daily is about 8000 milliliters. Drinking water on an empty stomach before meals, the water is in the stomach.

It only takes 2 or 3 minutes to quickly enter the small intestine and be absorbed into the blood. It can be replenished to all the cells of the body in about an hour, supplying the body’s need for water. Therefore, drinking water before meals can ensure the secretion of necessary and sufficient digestive juices, thereby promoting appetite, aiding in the digestion and absorption of the human body, and at the same time, it does not affect the physiological water content in the cells of the tissues.

One should drink a glass of plain water on an empty stomach after waking up in the morning, because after a night’s rest, the body loses a lot of water, so it should be replenished in a timely manner. Is it good to drink plain water before going to bed at night? This question should be looked at in two ways. For middle-aged and young adults, it is best to drink less water before going to bed, otherwise, it will increase the burden on the kidneys, which is easy to cause edema. When you wake up the next morning, your eyes will be puffy.

Moreover, drinking too much water before going to bed can lead to frequent nighttime urination, which can affect the quality of sleep. However, for the elderly, it is advisable to drink some plain water before going to bed. Otherwise, it can lead to increased blood viscosity and concentration, which can easily cause the formation of blood clots in the body, especially for the elderly with cardiovascular and cerebrovascular diseases. Drinking a glass of water before going to bed at night can effectively prevent fatal cerebral and myocardial infarction.
