1. Digestive system: People who drink tea for a long time are more prone to gastrointestinal reactions than those who drink boiled water for a long time, because tea contains caffeine, tannic acid and other substances, which may cause some discomfort and irritation, especially those who are prone to gastrointestinal cramps and diarrhea. However, boiled water does not have these problems.
2. Nutritional intake: Drinking strong tea can bring some nutrients to the body, such as tea polyphenols and catechins. However, in general, these components only exist in trace amounts in ordinary tea that is consumed daily, and most of them cannot be absorbed by the human body. And boiled water does not contain any nutrients.
3. Water supply: Whether drinking boiled water or drinking tea for a long time, you can supplement the water your body needs. However, it should be noted that excessive intake of diuretic drinks (such as strong tea, coffee, etc.). ) will accelerate the body's excretion of water, which may lead to dehydration of the body and burden the kidneys.
4. Impact on health: Caffeine and tannic acid in tea have different effects on human body. For example, caffeine has a certain exciting effect, which can improve people's alertness and attention; Tannic acid can converge tissues and inhibit inflammation. Of course, some people are allergic or intolerant to the substances in tea, such as dizziness and palpitation. At this time, it is necessary to reduce the intake of tea in moderation.
In short, when choosing between boiled water and tea, we need to make a comprehensive comparison according to our physical conditions, tastes and preferences, environmental temperature and other aspects. If we can balance the two, it will be more beneficial to our health.
