Drinking coffee is refreshing and needs to drink properly, which is harmful to the body.
Because office workers often work overtime, coffee is indispensable at this time, because coffee can not only refresh, caffeine can stimulate the cerebral cortex, eliminate drowsiness, so it is very popular among office workers. Coffee does more good than harm to your health, but don't drink freely because of it, or your body will protest.
The side effects of coffee on the body
1. Heart
Caffeine acts on the heart in two ways: in addition to affecting the brain center that regulates the cardiovascular system, caffeine also acts directly on the heart. High doses of caffeine can increase the heartbeat of people who do not tolerate caffeine by 10 to 20 beats per minute and may cause temporary arrhythmias in some people. Therefore, moderate consumption of drinks containing caffeine (an average of up to 500 mg per day) does not significantly increase the risk of heart disease, but exceeding this dose may increase the risk of myocardial infarction.
2. Kidney
It is a common occurrence for many people to go to the toilet after drinking coffee in the morning. This is because caffeine affects adenosine receptors in the kidneys, acting like diuretics. Caffeine may also slow the brain's release of an antidiuretic hormone that reduces urine production.
3. Digestive system
The acid, oil and caffeine in coffee may stimulate gastric mucosa and promote gastric acid secretion. Long-term consumption of drinks containing caffeine can lead to stomach problems.
4. Respiratory system
Caffeine and similar drugs have two effects on respiration. One is to increase the respiratory rate. In addition, caffeine relaxes the smooth muscle around the trachea, thus dilating the trachea and increasing breathing. However, caffeine can not be used as a drug to treat asthma.
Although coffee is good, drinking too much will have an effect on your health. In recent years, there have been cases of short-term memory loss caused by drinking coffee. Although this is only an isolated case, it is better to drink less coffee.
