The human body loses about 450 ml of water every night, and it will be in a physiological water shortage state after getting up in the morning. It is best to drink a cup of warm water on an empty stomach before eating, which can quickly dilute the blood and improve dehydration at night. If possible, you can add a slice of fresh lemon to remove stool and toxins.

2. Before going to bed at night

Don't drink too much water before going to bed, otherwise getting up frequently will affect your sleep, but you can't help drinking water. You should have a drink before you go to bed. Because when people sleep, the water in the body is lost, which leads to the decrease of water in the blood and the increase of blood viscosity. Drinking some water properly before going to bed can alleviate this phenomenon, thus reducing the risk of cerebral thrombosis. In addition, it is best for the elderly to put a glass of water at the bedside before going to bed. If they feel thirsty, they need a few drinks at once.

3. Before leaving the office after work

Office workers often ignore drinking water because of their busy eight-hour work. It is suggested that these people form the habit of drinking a few mouthfuls of water before going to work. Because not drinking water for a long time will damage the bladder and kidneys, which will easily cause backache and affect work efficiency. You don't need to drink too much at this time. The amount of a paper cup is enough, otherwise it is easy to "urinate urgently" on the way to work.

4. After eating salty food

Eating too salty will lead to high blood pressure, decreased saliva secretion and edema of oral mucosa. If you eat salty, you should drink plenty of water first, preferably cold boiled water or lemonade. Try not to drink sugary drinks or yogurt, because sugar will aggravate thirst. More than 90% of light soybean milk is water, and it is rich in potassium, which can promote sodium excretion and is also a good choice.

5. Half an hour after dinner

Don't drink water immediately after meals, otherwise it will dilute saliva and gastric juice, weaken the activity of protease and affect digestion and absorption. It is suggested that ordinary people drink water for half an hour after meals, about 200 ml. Take a sip when drinking, or you will burn your heart if you drink a lot of water frequently. People who are prone to heartburn should take 3-4 sips every 20-30 minutes 2-3 hours after meals.

6. After turning on the air conditioner for half an hour

Dry air in air-conditioned rooms can easily lead to water loss, dry nasal mucosa and even bronchitis. Therefore, if you stay in the air-conditioned room for more than half an hour, you should replenish water in time, such as boiled water, mineral water and lemonade. The water temperature is about 40℃.

7. After taking a shower

Many people often feel thirsty after taking a shower, so they take a glass of water and drink it down. As we all know, after taking a hot bath, the heated blood vessels of the body dilate, the blood flow increases and the heart beats faster than usual. Drinking too fast will be harmful to your health, especially for the elderly. Drink a glass of warm water slowly.

8. When constipated

Lack of water is one of the causes of constipation. People with constipation can drink plenty of water properly, and they must swallow it whole, so that the water can reach the intestine as soon as possible, stimulate intestinal peristalsis and promote defecation. While supplementing water, you can also eat some fruits and vegetables rich in dietary fiber such as leeks, celery and apples, which has a good effect on relieving constipation.

9. When you have a fever

When people have a high fever, they will dissipate heat in the form of sweating, which will consume a lot of water and seriously cause dehydration. Therefore, it is important to replenish water in time during fever. You can drink warm boiled water or warm glucose water several times, about once every half hour. Drinking millet porridge and mung bean soup is also a good choice.

10. When you are sad

Adrenaline is often called "pain hormone". When a person is upset, adrenaline will soar. Like other body toxins, it can be excreted with water. Therefore, when you are upset, you might as well pour a cup of warm water and sit in your seat and drink it slowly, which will make you feel much more relaxed.
