In a bustling city, in a simple but warm clinic, Dr. Li is chatting with his patient, Mr. Zhang.
Mr. Zhang is a postman, and his daily work is in the wind and rain, but because of his high blood pressure, he has to pay attention to his diet and lifestyle at all times.
"Dr. Li, I heard that drinking tea in people with high blood pressure can affect blood pressure, is this true?" Mr. Zhang looked at Dr. Li with anticipation and curiosity in his eyes.
Dr. Lee smiled, he had answered this question countless times, but he never got bored because he knew that every answer might help patients better understand their physical condition.
"Mr. Zhang, this question is very good, there are indeed many misunderstandings about the relationship between drinking tea and blood pressure. But in fact, as long as you pay attention to a few small details, people with high blood pressure can also enjoy the pleasure of drinking tea. ”
Mr. Zhang asked curiously, "What are the details?" "First of all, we have to pay attention to the type of tea." Dr. Lee began to explain, "Different tea leaves contain different amounts of caffeine. ”
"For example, green tea contains less caffeine than black tea, while pu-erh tea is relatively mild. People with high blood pressure should choose low-caffeine tea, which can reduce the impact on blood pressure. ”
Mr. Zhang nodded, seemingly interested in the information. "Is there anything else to pay attention to besides the type of tea?"
"And, of course, time for tea." Dr. Lee continued, "It is not advisable to drink tea on an empty stomach, as it may stimulate excessive stomach acidity, which may cause adverse effects on the stomach and indirectly affect blood pressure. It is best to drink half an hour to an hour after a meal, which not only helps digestion but also avoids sudden shocks to blood pressure. ”
"Listening to you say this, I did have some habits that were not right before, and I often drank tea on an empty stomach in the morning." Mr. Zhang said thoughtfully.
"Another important point is the temperature of drinking tea." Dr. Li added with a smile, "Don't drink tea that is too hot. Overheated drinks can cause blood vessels to dilate dramatically, which can be a risk for people with high blood pressure. The suitable temperature is between 40 and 50 degrees Celsius, which can not only retain the aroma of the tea leaves, but also do not cause a burden on the body. ”
Mr. Zhang listened very carefully and nodded from time to time, obviously very interested in these knowledge points.
He suddenly asked, "Dr. Li, can you give me a few specific examples of the low-caffeinated tea you mentioned earlier?" ”
"Absolutely." Dr. Lee went on to say, "Like white tea and yellow tea, the caffeine content is relatively low. In addition, some herbal teas, such as chrysanthemum tea and honeysuckle tea, are not only low in caffeine, but also have the effect of clearing heat and detoxifying, which is very suitable for patients with high blood pressure. ”
Time passed imperceptibly, and Mr. Zhang seemed to be more and more interested in this knowledge related to high blood pressure and tea drinking. Just as their conversation was about to end, Mr. Zhang suddenly remembered a question.
"Dr. Li, does drinking tea help lower blood pressure? I'm still a little worried. "Mr. Zhang's question hits the nail on the head.
Dr. Li smiled slightly and gave a professional answer: "Mr. Zhang, drinking tea does not have a big direct impact on blood pressure, but a reasonable tea drinking habit can assist in the management of blood pressure. ”
"For example, moderate amounts of tea polyphenols and catechins can help soothe blood vessels and indirectly help regulate blood pressure. But this is not an immediate effect, but a lifestyle adjustment that requires long-term adherence. ”
