1. Drink water after three meals
Doctors recommend drinking water half an hour after meals, but modern people are accustomed to drinking beverages instead of plain water. In fact, drinking a can of beverage after each meal can replenish about half of the daily water requirement. However, one should be cautious when choosing beverages; sports drinks or vegetable and fruit juices are the best options. Vegetable and fruit juices can provide a variety of nutrients, while sports drinks contain appropriate electrolytes and have an osmotic pressure similar to that of the human body, making them more easily absorbed than water. Recently, "light" sports drinks have appeared on the market, which are a suitable choice for office workers who are not regularly active to replenish fluids and electrolytes.
2. A glass of water upon waking
The morning can be considered the best time of the day to replenish fluids. 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 one feel refreshed and alert.
3. A glass of water before bed
The body naturally sweats during sleep, losing fluids and salts unknowingly. For the eight hours of sleep, the body cannot replenish fluids, which is why one often feels a dry mouth upon waking in the morning. Therefore, doctors recommend replenishing fluids and electrolytes half an hour before bed. This allows the body to maintain a balanced state during sleep and also reduces the concentration of urine, lowering the risk of kidney stones.
