Water is the source of life. About 70% of the Earth's surface is covered with water, and without it, there would be no life on our planet. The human body is nearly 70% water, with blood being about 80% or more water. A nursing infant's body is 90%-80% water, an adult's is 70%-60%, and an elderly person's is 60%-50%. Eating when hungry and drinking when thirsty seems like the most natural and obvious thing to do, but it's actually not that simple. There is a great deal of knowledge involved in drinking water. Learning to drink water scientifically can make your body healthier. tips1: A glass of water upon waking
Morning can be said to be the best time of the day to replenish water, because drinking water in the morning can immediately awaken the digestive system, stimulate peristalsis, and prevent constipation. More importantly, after a long period of sleep, blood concentration increases.
At this time, replenishing fluids can quickly lower blood concentration, promote circulation, and make you feel refreshed and alert.
tips2: A glass of water before bed
The body naturally sweats during sleep, losing water and salt without realizing it. For the eight hours of sleep, the body cannot replenish fluids, which is why you often feel a dry mouth upon waking. Therefore, doctors recommend supplementing with water and electrolytes half an hour before bed to maintain the body's balance during sleep, while also reducing urine concentration and lowering the risk of kidney stones.
tips3: Don't wait until you are thirsty to drink water
Feeling thirsty indicates that the body's fluid balance has been disrupted and cells are in a state of mild dehydration.
If you only drink when you are thirsty, it's like watering the crops only after the land has cracked—it's too late.
You should develop a good habit of drinking water frequently, in small amounts, to keep the body's fluids in a healthy state.
tips4: Avoid drinking a large amount of water all at once after exercise
Although you lose a lot of water during summer exercise, you should not drink large quantities of water quickly. Instead, you should drink "small amounts frequently."
To compensate for the water lost during exercise, you should replenish it before, during, and after. It is recommended to drink 300-500 ml before exercise, 150-250 ml every 15 minutes during exercise, and then make up for any remaining water loss after exercise.
tips5: It's advisable to drink water on an empty stomach before meals
About an hour before each meal—breakfast, lunch, and dinner—you should drink a certain amount of water. When you drink water on an empty stomach before a meal, it only stays in the stomach for 2 to 3 minutes, then quickly enters the small intestine, is absorbed into the blood, and is supplied to the body's tissues and cells about an hour later. Therefore, replenishing water before meals is very important. This is especially true for breakfast, as you have lost a significant amount of water during the long night, so drinking plenty of water upon waking is crucial.
