Be particular about drinking water in summer.

You sweat a lot in summer, and you sweat profusely during exercise. This raises a series of questions for people: What kind of water is good to drink in summer, how much should you drink each time, and how to control the total amount?

Drink plain water after exercise

Athletes cannot ignore drinking water. So, what kind of water is good to drink? It is said that along with the loss of large amounts of sweat, in addition to water, there are also minerals such as calcium and magnesium. But the top priority is not to supplement various minerals, but ordinary boiled water. Because the loss of minerals is only minimal, it can be replenished calmly after exercise. Quite a few people believe that some sodium chloride (salt) should be added to the water you drink after sweating. This is actually wrong. When you lose water due to exercise (or labor) in summer, you should first consider drinking water without salt.

Sugar is the energy substance that can be converted into energy most quickly. Does drinking sugary drinks kill two birds with one stone? Experts' opinion is that it is not necessary to drink sports drinks containing a small amount of sugar and electrolytes, unless it is after continuous long-term exercise. It is good to drink plain water for normal exercise.

Drink no more than 500 ml of water each time

Drinking more white tea in summer is good for your health

Tasting tea: Drinking more white tea in summer is good for your health

Tea is divided into black tea, green tea, oolong tea and other types according to different fermentation degrees and production methods. But have you heard of "white tea"? Recently, the British magazine "Best Nutrition" introduced that compared to green tea, white tea retains more nutrients in the tea leaves due to its simple production process.

In China, white tea is not as common as green tea, oolong tea, etc. However, there are also different varieties such as Silver Needle Pekoe and White Peony. In the UK, drinking white tea is very popular. Experts point out that the so-called white tea is made from tea leaves picked in early spring. At this time, the tea leaves and tea buds are relatively young, and the green leaves are covered with white hairs, so it is called "white tea".

White tea is simpler to make than black tea and green tea. Generally speaking, green tea is unfermented tea, and its production requires processes such as picking, frying, rolling, and drying. Black tea undergoes complete fermentation, with a fermentation degree of 80%-90%. The production process includes picking, withering, rolling, etc., but does not include fried green tea. White tea is made by picking the tea leaves, only undergoing a slight fermentation of about 10%-30%, and then directly drying or drying them without any frying or rolling. Because the production process is simple and processed with minimal steps, white tea retains the nutrients in the tea leaves to a large extent.

Experts point out that compared with green tea and oolong tea, white tea has a higher content of tea polyphenols, which are natural antioxidants that can improve immunity and protect cardiovascular systems. White tea also contains active enzymes necessary for the human body, which can promote fat catabolism, effectively control insulin secretion, decompose excess sugar in the blood in the body, and promote blood sugar balance.

In addition, people who often drink white tea in summer rarely suffer from heatstroke. Experts believe that this is because white tea contains a variety of amino acids, which have the effects of reducing fever, dispelling heat, and detoxifying. The bactericidal effect of white tea is also stronger than that of green tea. Dr. Milton Schiffenberg of Pace University in New York recently pointed out that he and researchers put white tea into toothpaste and then applied it to a laboratory bench with bacteria. Experiments have shown that toothpaste mixed with white tea has significantly enhanced bactericidal ability. Therefore, he believes that drinking more white tea can help keep your mouth clean and healthy.

Although exercise in summer will cause a lot of water loss, when replenishing water, it should not be too much at one time. It is best to keep the water flowing slowly. Although boiled water is the fastest way to reach dehydrated tissues, it should not exceed 500 ml at a time. If it exceeds 600 ml, gastric absorption will slow down. During exercise, you will feel water sloshing in the stomach, and your abdomen will feel full, and your exercise speed will slow down. will be significantly reduced.

If you want to drink some sugary drinks and add some energy while drinking water, 10% sugar water is ideal. The absorption speed of sugar water with this concentration is similar to that of boiled water. However, sugar water with a concentration of 10% or more that is too sweet stays in the stomach for too long, so the absorption speed is significantly slowed down. On the contrary, "far water cannot quench near thirst".

Watermelon can be eaten raw to cool down the heat, and it can also be made into delicious cold watermelon. Here are two preparation methods.

1. Watermelon cheese Ingredients: watermelon, sugar, water, agar (agar) Preparation method: Wash the watermelon, remove the seeds from the pulp, and cut into small cubes.
