Maintaining sufficient water intake every day is crucial for the health of the human skin, blood vessels, and intestines.

More unobstructed blood flow: sufficient water helps blood flow smoothly, and the risk of thrombosis is relatively lower;

Prevention of constipation: Adequate water can prevent dry stools and prevent constipation;

Drink water and have a suitable amount

The saying 'drink 8 glasses of water every day' is widely circulated, and many people insist on following it, but in fact, this standard is not suitable for everyone.

01

Water consumption standards for the general population

The "Dietary Guidelines for Chinese Residents (2022)" states that adult males with low levels of physical activity should drink 1700ml per day, while adult females should drink 1500ml per day.

If the weather is hot, the air is dry, and there is excessive sweating, it is necessary to increase the amount of drinking water appropriately according to the actual situation.

Everyone can pay attention to their urine. If the color is light yellow, clear, and sufficient, it indicates that the water intake is basically sufficient. Otherwise, it is necessary to drink more water.

02

Special populations need to control their drinking water intake

Patients taking medicine to treat gastric ulcer: the medicine contains sucralfate, aluminum hydroxide gel and other substances, which will protect the gastric mucosa. If you drink too much water, it may reduce the efficacy, which is not conducive to the recovery of the disease.

Chronic kidney disease patients: When kidney function is impaired, the water they drink cannot be excreted into the body normally, so it is necessary to control the amount of water they drink.

Generally, the appropriate amount of water for the entire day (including drinking water and fluids in the diet)=500ml+the amount of urine used the previous day.

Patients with uremia: The amount of water they drink at this time needs to be determined based on their weight changes.

You can weigh your weight at a fixed time every day (after urination and before breakfast is more appropriate), and the daily weight gain should not exceed 0.5% of your body weight; In addition, during the two dialysis periods, the weight gain was less than 3% to ensure the dialysis effect.

Heart failure patients: Drinking a large amount of water can increase the amount of blood returning to the heart, thereby increasing the heart load and exacerbating the condition. For those with severe heart failure, the amount of water consumed should even be controlled within 800ml, and specific medical advice should be followed.

Reduce the incidence of cardiovascular diseases

A study published in the European Journal of Preventive Cardiology, which included 100902 participants aged 18 and above, followed up for 17 years and found that people who drank tea 3 times a week compared to< For those who have been treated three times, the incidence rate of cardiovascular and cerebrovascular diseases has decreased by about 20%, the mortality rate has decreased by about 22%, and the total risk of death has decreased by about 15%.

Auxiliary depressurization

The American College of Cardiology compiled 21 effective studies, including 1323 participants. It was found that compared to non tea drinkers, tea drinkers had an average decrease in systolic blood pressure of 1.8 mmHg and diastolic blood pressure of 1.4 mmHg, and those who drank tea for more than 12 weeks had a more significant antihypertensive effect.

Beneficial for weight loss and lipid reduction

The tea research institute of Zhejiang University found that the complex catechin in tea, epigallocatechin gallate (EGCG), can consume excess energy by increasing the heat production of brown adipose tissue, thus helping to lose weight;

At the same time, it can also inhibit microglia, reduce hypothalamic inflammation, improve weight, and regulate the normal function of the central nervous system.

Drinking tea, emphasizing the "Four Nos"

Tea is not something that everyone can drink, nor can it be consumed at any time:

01

People who are not suitable for drinking tea

Patients with neurasthenia, insomnia, hyperthyroidism, tuberculosis, heart disease, stomach disease, and intestinal ulcer are not suitable for drinking tea, especially strong tea; There are also lactating or pregnant women and infants who are not suitable for drinking tea.

02

Do not drink before waking up or going to bed, and do not drink before or after meals

Drinking tea on an empty stomach in the morning can dilute gastric juice and reduce digestive function; Tea has a refreshing, stimulating, and diuretic effect, and drinking it before bedtime can affect the quality of sleep. It is recommended to drink tea around 10 am.

Theophylline can inhibit gastric juice secretion, but drinking tea before meals is not conducive to digestion and absorption; Drinking tea immediately after meals can affect the absorption of protein, iron, and other nutrients by the human body. So it is recommended to drink one hour after meals.

03

Do not drink certain medications when taking them

Some people who need to take sedative and hypnotic drugs, as well as antiarrhythmic drugs, are not recommended to drink tea because the theophylline and other components contained in tea can reduce its efficacy, which is more unfavorable for disease control.

04

Not too thick

Strong tea contains high levels of fluoride. Drinking strong tea regularly can damage the kidneys, increase the burden on the intestines and stomach, and can also easily cause "tea type fluorosis".

Therefore, it is appropriate for healthy adults to drink around 12 grams of tea a day, 3 grams each time, and brew with 150 milliliters of water.

Remember four points, correct hydration is healthier

plain boiled water4

01

Active drinking

Don't wait until you are thirsty to drink water, because thirst is actually a signal of a clear lack of water in the body. As the amount of water lost in the body increases, it will also be accompanied by symptoms such as darkened urine color, dry skin, cracked mouth and tongue, hoarse voice, and overall weakness.

So it's best to supplement every half hour.

02

Swallow slowly

Even if you are thirsty, don't gulp down on water. If you drink too much water in large gulps, it can cause water to quickly enter the bloodstream. After absorption in the intestines, the blood will become thinner, and the circulating blood flow will suddenly increase in a short period of time, which can easily increase the oxygen consumption of the myocardium and worsen the heart load.

The correct method is to take small sips and drink slowly, especially for those with cardiovascular and cerebrovascular problems. It is advisable to drink slowly and in small amounts multiple times.

03

Don't be too hot

Overheated water (over 65 ) can burn the esophageal mucosa. Over time, the esophageal mucosa is repeatedly damaged and repaired, which can easily lead to inflammation and even cancer.

04

Choose the right variety

There are many varieties of tea, and one should learn to choose according to time

In spring, Yang Qi generates and can easily cause hyperactivity of liver Yang, so it is suitable to drink green tea to soothe the liver and relieve depression;

Summer weather is hot, with a high incidence of cardiovascular events, suitable for fully fermented black tea;

Autumn is dry and prone to consuming body fluids, making it suitable for drinking white tea to clear heat and moisten the lungs;

Winter weather is cold, and the kidneys need to store essence for the winter, while black enters the kidneys, so it is suitable for drinking black tea
