The answer is yes!
Both black tea and green tea have a certain antihypertensive effect.
Let's take a look at the data first:
Khalesi's research on 20 14 systematically reviewed the papers published in 1995-2065 438+03 on the relationship between green tea and blood pressure. The results showed that drinking green tea could reduce systolic blood pressure by 2.08 mm Hg and diastolic blood pressure by 1.7 1 mm Hg.
20 14, Grey studied the relationship between black tea and blood pressure. The results show that drinking black tea regularly can reduce systolic blood pressure by 65438 0.8 mm Hg and diastolic blood pressure by 65438 0.3 mm Hg.
The paper published by Liu Gang on 20 14 shows that drinking green tea can reduce systolic blood pressure by 2. 1 mmhg and diastolic blood pressure by 1.7 mmhg. The systolic blood pressure and diastolic blood pressure of drinking black tea decreased by 65438 0.4 mm Hg and 65438 0.65438 0 mm Hg respectively.
In 2004, Yi-Ching Yang et al. studied the relationship between drinking tea and blood pressure in 77/kloc-0 men and 796 women, and found that people who drink at least 120 ml of medium-intensity green tea and oolong tea every day have a lower risk of hypertension than those who don't drink tea. People who drink 120-599 ml every day,
There are many such studies, so I won't list them one by one. From these studies, we found that whether it is green tea, black tea or oolong tea, as long as it is drunk for a long time, it can help to lower blood pressure. Drinking green tea is similar to drinking black tea in lowering blood pressure, and it is hard to say who is better than who. From the data point of view, the antihypertensive effect of green tea is slightly higher than that of black tea. Because of the different factors involved in various studies, different studies still have different results, but the overall research results show that drinking tea is negatively correlated with the increase of blood pressure!
Experimental data show that tea and tea extracts play an important role in relaxing smooth muscle contraction, reducing vascular inflammation, inhibiting renin activity and resisting vascular oxidative stress. It is precisely because of these effects that tea and tea extracts have the effect of lowering blood pressure.
We must have a correct understanding of tea's lowering blood pressure, that is, it does not lower blood pressure much, it can only play an auxiliary role. If the blood pressure of a hypertensive patient is already very high, it is totally unrealistic to control blood pressure simply by drinking tea! Still have to accept the advice of regular doctors, use drugs scientifically and rationally, and adjust their diet and living habits. Meanwhile, drinking tea can better control blood pressure!
For friends with high blood pressure, we must eat reasonably and control the intake of salt. It is suggested that the daily salt intake should be gradually reduced to 5 grams, and at the same time, attention should be paid to reducing the use of sodium-containing condiments, such as soy sauce and fish sauce. It is necessary to increase the intake of vegetables, fruits, low-fat dairy products, deep-sea fish, whole grains, fiber-rich ingredients and foods rich in potassium and minerals.
At the same time, we should also pay attention to controlling our weight. We can gradually control our weight by jogging, swimming and brisk walking. In the process of exercise, you must not force your grades, take your time. Anaerobic exercise can be properly carried out, but remember to rush the weight and compare with each other, which may easily lead to cardiovascular and cerebrovascular accidents. Aerobic exercise is recommended to be at least 150 minutes a week, that is, 30 minutes a day, at least 5 times a week!
Note that at least this amount of exercise can be adjusted according to personal physique!
Aerobic exercise emphasizes moderate intensity aerobic exercise, that is, you can talk comfortably with other friends during exercise, but it will not induce abnormal emotions such as palpitation, palpitation and shortness of breath. Research shows that scientific aerobic exercise can reduce systolic blood pressure by 3.84 mm Hg and diastolic blood pressure by 2.58 mm Hg.
In addition, I believe everyone must know that friends with high blood pressure do not recommend smoking and drinking. These two habits are not good for our health. If you already have high blood pressure and have these two habits, I suggest you quit! If you really need to drink occasionally, it is recommended that men drink no more than 25 grams, and women drink no more than 15 grams, which is close to 75 ml of low-alcohol liquor and beer.
Drinking tea is a very healthy lifestyle with a long history in China. With the deepening of research, we also found that drinking tea does have a certain lowering effect on our blood pressure, whether it is black tea, green tea or oolong tea. If you don't have this habit, cultivate it slowly!
At the end of the article, Dr. Xie also wants to talk to friends with hypertension. Drinking tea is a very good habit, but you must pay attention to it. If your blood pressure really rises significantly, you must use drugs scientifically and rationally with the help of cardiologists, and then gradually adjust your living and eating habits, limit salt, pay attention to rest, don't stay up late for a long time, and increase the intake of fresh vegetables, cereals and other ingredients. We must control our weight, keep exercising, avoid drinking and form good living habits. We can control our blood pressure slowly. For controlling hypertension, drugs and living habits are the foundation, and drinking tea properly is the icing on the cake. Never put the cart before the horse!
If you also have the habit of drinking tea and have some ideas about drinking tea, please leave your opinion at the bottom of the article!
