With the promotion of health tea, what are the advantages and disadvantages of drinking black tea?
With the promotion of health tea, more and more people began to use tea for health preservation, which is undeniable, which is a good thing. Tea is good tea. If you drink too much for your health, it may be harmful to your health if you drink it wrong. The first thing we need to know in life is the nature of tea, because people's bodies are also cold. To understand the nature of tea, we can probably start with the tea-making technology and classification of tea.

According to the tea-making technology, tea can be divided into three categories: unfermented tea, semi-fermented tea and fully fermented tea, in which unfermented tea belongs to herbal tea and fully fermented tea is relatively mild. The green tea we often drink in our life belongs to unfermented tea, which is cold in nature; Black tea belongs to fully fermented tea, which is warm in nature, and oolong tea is between cold and warm.

Speaking of the benefits of drinking black tea, it is everywhere. For example, as mentioned in our daily life, promoting fluid production and clearing away heat, relieving summer heat and quenching thirst, and regulating body temperature are the most noticeable effects of drinking tea in summer. And loss of appetite in summer, barbecue needs digestion and so on. Black tea is often mentioned in these situations. Drinking black tea can also promote appetite and help digestion, killing two birds with one stone!

Caffeine in black tea can achieve refreshing effect and promote metabolism; There are anti-inflammatory polyphenols in tea, but we often hear that black tea is more suitable for people with cold body than green tea. Why? In fact, compared with green tea, tea polyphenols in black tea will be oxidized after drinking, and the stimulation to the stomach will be much weakened. This is very important for people who have a cold or hidden diseases in their stomachs.

Let's talk about the pros and cons first. Tea has a refreshing effect, so don't drink it before going to bed. You can have tea half an hour after dinner and before going to bed 1 hour. Black tea is fermented tea, which may be contaminated with impurities on the way, so wash the tea first; Avoid drinking black tea at special times, such as when you have a holiday; Black tea is not suitable for drinking after cooling. The temperature of tea is suggested to be around 45℃, and the highest temperature should not exceed 65℃, otherwise it will easily cause esophageal injury.

Drinking tea on an empty stomach will reduce the digestive function and easily cause symptoms of palpitation and dizziness, so you should not drink tea on an empty stomach, let alone drink too strong tea. After understanding these matters, as long as you avoid these taboos when drinking tea in the future, there will be no side effects caused by drinking black tea.
