Two special water replenishment times

Water is the source of life. Without water, human beings cannot survive. It is a precious and unique universal solvent for human body to participate in life movement, eliminate harmful toxins, help metabolism, maintain aerobic respiration, etc. We need water very much in two special water replenishment times. Let's understand

Physiological function of water in human body

1. It helps digest the food we eat in our mouth. After the teeth are chewed and saliva is moistened, the digestion process from esophagus to gastrointestinal tract is completed and absorbed. All these links need water to participate in, so as to accelerate the dissolution of body fluids to nutrients.

2. After the digestion and absorption of the nutrition of the excreted waste food, the residual waste should be discharged out of the body through sweating, breathing and excretion. These different excretion methods can only be realized with the help of water.

3. Lubrication joint between human joints

There should be lubricating fluid to avoid damaging friction between bones, and water is the main source of joint lubricating fluid.

4. Balance body temperature when the ambient temperature is lower than the body temperature, in order to maintain the body temperature and ensure normal physiological activities, the water in the body will be retained in the body due to the reduction of evaporation of the shrinking pores; when the ambient temperature is higher than the body temperature, the water will be discharged from the body through the dilated capillary breathing holes to reduce the body temperature. The body ensures the survival function through the flow of water.

5. Maintaining cell water can promote cell metabolism, maintain normal cell morphology, and keep skin moist and elastic.

Two special water replenishment times

1. During exercise

Long time training will make the body sweat a lot, and the amount of plasma will be reduced by 16%. Timely water supplement can increase the amount of plasma, reduce blood flow resistance, and improve the working efficiency and exercise duration of the heart. Water lost in training should be replenished in time. Make up water 30 minutes before training. If you are thirsty during training, you can use a small amount of water at rest. When carrying out super intensity training, in addition to replenishing water before training, water should also be replenished after training.

2. When sick

People with constipation should pay special attention to absorb enough water. Drinking more water can stimulate the peristalsis of the intestine and soften the stool.

Drink more water when you have a cold and fever, which can help your body cool down.

Patients with cystitis should drink more water than usual to increase the amount of urine, increase the amount of flushing and circulation, and relieve inflammation.
