Drink a glass of water on an empty stomach in the morning.
You can drink a glass of water on an empty stomach after getting up, because when you sleep, your body sweats and excretes urine, which leads to a lot of water loss. Even if you don't feel thirsty after getting up, your blood will still be sticky because of lack of water. So after getting up, you must drink a glass of water to replenish water slowly.
A glass of water before bed
When people sleep, sweat glands are still draining. When the water in the body decreases too much, the blood viscosity increases. A glass of water before going to bed can effectively reduce blood viscosity and prevent angina pectoris, myocardial infarction and other diseases that are easy to occur in the early morning of autumn and winter.
A glass of water after exercise
Old people should pay special attention to replenish water after exercise. Sweating during exercise takes away electrolytes and consumes more energy. If you don't pay attention, it is easy to have hypoglycemia after exercise, and even cause syncope. Therefore, after exercise, it is suggested that the elderly should drink light salt water and light sugar water according to the actual situation.
The above describes how to drink the "three glasses of water" for the elderly. For the elderly, we must pay attention to a reasonable diet and drink more water to make them healthier.
