Xiaofang saw an article on the Internet, "You can't drink too much tea, or you have a headache and hurt your stomach", which made him sneer. Grandpa was in his sixties and had been drinking tea for half his life, but his body has never had any major problems.
In fact, in everyone's impression, tea is a very healthy drink, but with the development of science, more and more people begin to question this traditional impression.
The new generation believes that drinking tea is actually not that healthy. For example, strong tea, overnight tea, cold tea, etc., everyone knows that you can't drink it, and drinking too much tea can easily cause insomnia.
The traditional school refutes: tea is good for health, and there is nothing wrong with something that has been passed down for thousands of years.
So is there any health benefit to drinking tea regularly?
Whether tea is good for health or not, mainly depends on the ingredients in the tea. In fact, many people don't know that tea also contains caffeine.
Excessive caffeine intake can cause rapid heart rate, palpitations , and even seizures. In severe cases, it can be fatal.
Of course, we usually don’t consume so much caffeine, but too much caffeine can still cause obvious discomfort, so you should not drink more tea, especially strong tea.
Another main ingredient in tea is tea polyphenol . This substance has a strong antioxidant capacity and can protect our heart and brain blood vessels. Drinking in moderate amounts can improve the body’s immunity.
The tea polyphenols and caffeine in tea can stimulate nerves and produce excitatory effects, so drink tea in quantity.
Drinking too much tea is not only useless, but has three major hazards
Caffeine in tea has a diuretic effect. Simply put, after drinking tea, the excretion of water will be more than that of drinking tea. ,This can easily cause dehydration.
Some nerve-sensitive people will be in a state of excitement after drinking tea. Drinking tea at night will cause insomnia, which is equivalent to making you stay up late forcibly, increasing the burden on the heart and blood vessels, which is for middle-aged and elderly people and suffering from cardiovascular diseases It is very dangerous for patients.
Some people like to drink strong tea. In fact, strong tea will accelerate the hardening of the arteries of the human body. If you suffer from high blood pressure and other symptoms, you are more likely to experience stroke symptoms.
Drinking strong tea for a long time can also affect the body's gastrointestinal function, resulting in poor bowel movements.
To drink tea in a health science way
From the perspective of Chinese medicine, tea also has different temperaments, some tea is warm in nature, some is cold in nature.
In summer, the temperature is high and hot, drink more cold tea such as green tea , and drink some mild tea such as black tea in winter.
In addition to temperature and climate, we must also consider our own physical fitness. People with body cold should not drink cold and thin tea in summer, and people with hot stomach should drink less warm tea in winter.
These three kinds of tea cannot be drunk, it is more cost-effective to pour it out
The overnight tea cannot be drunk, the tea water is rich in substance, and it is easier to breed bacteria. It is placed for a long time on a cool night Time tea will breed a lot of bacteria.
Repeatedly brewed tea cannot be drunk. A pot of tea leaves can be brewed two or three times with hot water. Multiple brewing is neither tasteful nor healthy.
Do not drink tea before going to bed. Many people think that drinking tea is a kind of relaxing thing, but drinking tea can not help sleep. On the contrary, it will reduce the quality of sleep. It is easy to lose sleep or wake up midway.
Tea tasting is a very enjoyable thing, but friends who love tea should understand the above information, and don't let the incorrect way of drinking tea affect your health.
