Coffee is a very popular drink in the world. A cup of mellow coffee for breakfast can make a person full of energy for the day. In particular, many student parties and office workers are used to having a cup of refreshment in the morning to avoid sleepiness during the day, and it is definitely the best choice when working overtime and staying up late. Coffee can refresh and quickly restore energy, which is all due to the caffeine in it.

However, some people still have questions and concerns, will caffeine increase blood pressure or cause arrhythmia? Is it good or bad for the heart?

Caffeine is an adenosine receptor antagonist that affects cardiovascular function by affecting the release of catecholamines and neurotransmitters. Studies have found that drinking coffee has a beneficial effect on reducing the risk of cardiovascular disease when lifestyle factors such as smoking are excluded.

A recent study from the Harvard School of Public Health found that moderate (2-5 cups per day) coffee consumption was associated with a lower risk of cardiovascular disease. For most people, caffeine intake is limited to 400 mg per day, which is a healthy lifestyle.

Whether there is physical discomfort is related to the frequency of drinking

The study noted that caffeine intake induces adrenaline release and increases blood pressure in infrequent drinkers. However, it only takes a week to develop tolerance to these effects of caffeine if consumed daily. Randomized trials found that long-term caffeine intake increased blood pressure only slightly, possibly because other components in coffee interacted with caffeine.

Likewise, myocardial infarction may occur in people who drink infrequently, but may not usually occur in people who drink it regularly. But high caffeine intake from energy drinks, especially after heavy drinking and exercise, was associated with cardiovascular events.

These findings justify the cautious use of high-dose caffeine, but not too much of a concern for cardiovascular effects in people who consume caffeine on a regular basis. Additionally, habitual caffeine consumption reduces appetite and increases energy expenditure, which may benefit weight management and aid in lipid lowering.

There are three types of coffee on the market today:

The first is pure coffee, which is made from coffee beans and water. The second is mixed, that is, adding milk and sugar to pure coffee, such as cappuccino, mocha, latte, etc. The third is instant, which is a three-in-one of coffee, sugar, and creamer.

So how do these three affect our health?

The first is pure coffee. It is the object of the scientific research we introduced in the previous question. More and more scientific studies have proved that long-term drinking can reduce the risk of cardiovascular disease and the risk of type 2 diabetes; moderate drinking is also conducive to reducing malignant tumors, depression, breast cancer, elderly The occurrence of diseases such as dementia.

Therefore, it is concluded that if you drink coffee, please try to drink pure coffee for a long time. If you can't accept it in terms of taste, you can add milk. But don't add a lot of non-dairy creamer or sugar, which is very bad for your health.
