How to stay hydrated healthily during special times

1. Selection of drinking water types

It is recommended to drink purified water: Purified water, in short, is the purification of water. It is a process that removes iron rust, sand, residual chlorine, organic matter, harmful heavy metal ions, bacteria, viruses, etc. from water through corresponding filter materials, using physical or chemical methods, according to different end-use water needs. Obviously, if the entire water purification process uses physical filtration, it will not produce or add any new substances to the water, nor will it change the properties of the water, so it is the safest method and is widely used in Western countries. It is also the drinking water that is more suitable for human needs and should be the first choice.

2. Drink freshly boiled water

Boiled water that has been left for too long, boiled water that has been boiled for a long time, overnight reboiled water, repeatedly boiled water, and steamed soup water after steaming, etc., the beneficial elements in these waters are destroyed, and harmful substances such as nitrites increase.

3. Drink warm water

Water that is too cold will cause gastrointestinal discomfort, and long-term use will damage health. Water that is too hot will cause burns or even congestion of the oral mucosa, pharynx, esophagus, and stomach. Over time, it can lead to inflammation.

4. It is not advisable to drink salt water early in the morning

When you wake up in the morning, the blood has become concentrated. At this time, drinking a certain amount of plain water can quickly dilute the blood, correcting the hyperosmolar dehydration at night. Drinking salt water will worsen hyperosmolar dehydration, making you even thirstier. Drinking an appropriate amount of salt water after profuse sweating can replenish electrolytes.

5. Drink small amounts frequently

Daily water intake should be distributed throughout the day and before bedtime, rather than only drinking water when thirsty. Drinking water in the morning can replenish the water lost by the body's metabolism at night, cleanse the intestines and stomach to promote physiological function, be absorbed by the intestinal mucosa into the blood to increase blood volume, dilute the blood, promote blood circulation, lower blood pressure, and also moisten the intestines and prevent constipation. Drinking water one hour before bedtime can prevent dehydration during sleep to keep blood vessels unobstructed. Drinking about 250ml of water one hour before meals can increase saliva secretion, promote appetite, and aid digestion and absorption. It is not advisable to drink water within half an hour after meals.

6. How to ensure safe drinking water during the epidemic?

No garbage should be piled up or toilets built within 30 meters of the water source. Water pipes should be free of damage and should not run parallel to sewage pipes to prevent sewage from entering the water pipes. In order to maintain the disinfection effect of tap water and avoid microbial contamination during the process of transporting tap water to users through the pipe network, the chlorine dioxide content of tap water at the end should be no less than 0.02mg/L.

7. How to effectively remove the "chlorine smell" from tap water?

Chlorine disinfectants and disinfection by-products are not heat-stable and are easily volatilized by heating. When boiling water, open the lid, and turn off the heat 3-5 minutes after the water boils.
