In our daily life, drink water is one of the most usual things. We usually drink water filtered by the edr1rxd1 water filter and other usual water filters. Drinking tea is no substitute for drinking water? What is drinking water exquisite after all?
Many people have the habit of drinking tea, every day teacup does not leave the hand, that tea is also drinking water, and compared with plain water tasteless, tea fragrance and health. In fact, completely replacing water with tea is not a healthy lifestyle. How to drink tea correctly, drink water and what to pay attention to?
Studies show that catecholamines, tea polyphenols and other substances in tea can reduce body weight, fight inflammation, control blood sugar and prevent neurodegenerative diseases to a certain extent. However, most of these studies have been done on animals, and more research is needed to see if there will be any effect on humans.
Therefore, theoretically speaking, drinking tea can keep in good health, but can not put the hope of a strong body to tea.
Two to three cups of weak tea a day is enough, not a substitute for water. Tea contains beneficial ingredients called polyphenols, but also caffeine and oxalic acid, which your body may not be able to tolerate in excess.
To be specific, caffeine intake should be limited to 400mg per day, with 40-70mg of caffeine found in around 150ml tea, and higher coffee content in tea brewed repeatedly.
If you brew a large cup of tea all day or drink it entirely instead of water, you’re more likely to be drinking too much caffeine. It is not only very adverse to patients with hyperlipidemia, but also induces symptoms such as accelerated heart rate and palpitation. Excessive oxalic acid intake can also irritate the stomach lining and cause stomach upset.
Therefore, “completely replace water with tea”, “half a cup of tea a day” practices should be avoided. In general, drinking 2-3 cups of weak tea a day is appropriate. Here are some tips about drinking tea:
Don’t drink tea that is too hot right away.

Moreover, tea soaked for a long time will oxidize, which is also bad for human health.The tea polyphenols in the tea water will be further oxidized and the color of the tea water will be deepened. This is why a cup of clear green tea turns reddish brown when left overnight. Even whiter, overnight tea is more dangerous than tea that has been stewed for a long time.
