First, let's take a look at the causes of elevated blood pressure, and then look at the relationship between coffee and hypertension:
The root cause of high blood pressure is blood vessels and blood.
Hypertension is mainly divided into two types: primary hypertension and secondary hypertension. However, no matter which one is, the risk of disease will increase because of eating habits, irregular work and rest, obesity, excessive drinking, and high pressure, which is one of the reasons why modern hypertensive patients are gradually aging.
There are two main factors that determine blood pressure: Vascular resistance and blood flow.
- As the human body gradually ages, the blood vessels will age, and there will be a lot of "dirt" in the blood vessel wall, which will lead to the thickening of the wall and the narrowing of the diameter of the blood vessels, which is similar to blocking. In addition, the blood vessels will slowly lose their elasticity with age and become a curved pipe, making it difficult to deliver blood. Therefore, we have to increase blood pressure to make the blood flow more smooth.
- If the blood fat and cholesterol are too high, the blood viscosity will be too high, and the speed of blood flow will slow down. Many attachments will be deposited on the blood vessels, and the speed of blood flow will be slower and slower. Because every cell in the body needs to deliver nutrients through the blood stream, and then it can survive and continue metabolism. When the vascular resistance increases and the blood flow decreases, the heart can only use more force to reach its goal in order to deliver blood to all parts of the body, and the blood pressure also rises.
Caffeine and diterpenoids are the main components in coffee that affect blood pressure. The effects of caffeine on the human body vary with the concentration and amount of intake. Moderate concentration and proper amount of coffee can excite the human brain, invigorate the spirit and improve fatigue. But the caffeine in coffee will cause a short but violent rise in blood pressure, especially for obese or older people.
Some studies believe that this is because caffeine can inhibit a hormone that helps to dilate arteries, and also can promote the secretion of adrenaline, further promoting the rise of blood pressure. However, there is no research to prove that coffee can affect blood pressure for a long time.
For people with poor blood pressure control or poor blood pressure reduction effect, try to drink less or no coffee, not to mention drinking a lot of coffee in a short period of time or when feeling nervous, otherwise it will easily lead to heart palpitations, tachycardia and other adverse symptoms.
People who already have high blood pressure also include other caffeinated beverages, such as strong tea, which also contains high levels of caffeine. For people who have been used to drinking coffee for a long time, it is recommended to slowly reduce the amount of coffee they drink, and spend about a week to not drink it.
Because I stopped drinking coffee all of a sudden, it is easy to have caffeine phased headache, which makes people feel uncomfortable. In addition to patients with hypertension, normal people are not recommended to drink a lot of coffee, because excessive intake of caffeine will inhibit calcium absorption and increase the risk of osteoporosis. For those who cannot give up coffee, it is recommended to reduce the addition of sugar and other high sugar and high-fat condiments, so as not to cause excessive heat and aggravate the problem of hypertension.
No one knows our body better than we do. Daily blood pressure monitoring can help us better understand our own blood pressure and live a leisurely life.
