We all know that coffee is very good in life, and especially some young people nowadays are accustomed to drinking coffee, or milk tea, etc., so if we drink coffee frequently, what are the advantages and disadvantages to our body? Studies have found that how to drink it is more beneficial, and now we should take a look at it.

First: Coffee can improve our concentration. It is a common understanding that drinking coffee can refresh our mind. Drinking coffee can significantly improve our brain's spirit and concentration. At the same time, when the mind is more focused, our understanding and thinking ability will also be improved.

Second: Drinking coffee will speed up heart rate, enhance myocardial contraction, increase blood pressure, etc. Coffee also contains active substances such as diterpenoids, which may increase blood cholesterol levels.

Third: Normal coffee drinking will not cause palpitations. Some people think that coffee can induce palpitations because they drink coffee when they are working for a long time and are overworked. Coffee gives people the energy to continue to work hard and prolongs the state of fatigue, but coffee itself does not cause palpitations. Only when you drink a lot of coffee in a short period of time will you experience adverse symptoms such as palpitations and tachycardia.

Fourth: Coffee can reduce the risk of cardiovascular disease. Drinking 1.5 cups of coffee a day can reduce the incidence of cardiovascular disease by 11%; 3.5 cups a day can reduce it by 15%, which is the greatest benefit; 5 cups a day or more will have no effect. (A cup is about 150ml) Moreover, drinking a moderate dose of coffee a day can significantly reduce the risk of stroke.

Fifth: Pregnant women should not drink coffee. When pregnant women consume a large amount of caffeine, it may lead to miscarriage, dystocia or fetal abnormalities and other adverse risks. Therefore, pregnant women should reduce their coffee drinking during pregnancy.

Sixth: Hypertensive patients cannot drink coffee. For hypertensive patients who do not have the habit of drinking coffee, drinking coffee may cause a sudden increase in blood pressure. Therefore, if hypertensive patients do not have the habit of drinking coffee before, it is recommended not to drink coffee.

Seventh: The calories in coffee will increase due to condiments. The calories in coffee itself are not very high, but many people are used to adding sugar and milk when drinking coffee. These condiments will increase the calories in a cup of coffee by dozens of times. And these high-calorie coffees will increase the risk of cardiovascular disease.
