Reason:
1. When exercising, people's heart is more burdened and their heart beats faster. Tea contains caffeine, which can be exciting. At this time, a cup of strong tea will increase the burden on the heart and make people uncomfortable. At the same time, people with very poor health may lead to more serious consequences.
2. As the exercise time goes on, the body will lose a lot of water. At the same time, it also lost a lot of electrolyte. What is most needed at this time is to replenish water in time. However, tea has diuretic effect, mainly because tea soup contains purine compounds such as theanine, and the clinical test results show that theanine has the greatest diuretic effect. Therefore, it is best not to drink tea.
