What are the adverse effects of excessive caffeine

Young people nowadays love to drink coffee, and they feel that the bitter taste of coffee is very attractive. However, there are also some rules for drinking coffee. You should know that drinking coffee at the wrong time is harmful to the human body, especially when the intake of caffeine is excessive. The adverse effects are even more serious. However, it is precisely because many friends are not very clear about the adverse effects of excessive caffeine that they drink coffee recklessly. The specific hazards of excessive caffeine are as follows:

1. Caffeine poisoning

If you consume too much caffeine at one time, you are likely to experience symptoms such as "caffeine poisoning". It can be said that large doses of caffeine are a drug. Once caffeine poisoning occurs, patients will experience various discomfort symptoms, such as nervousness, irritability, anxiety, tremors, etc. In addition, there will be symptoms of muscle cramps, and some patients with milder symptoms will experience mild insomnia and palpitations. No matter how serious the symptoms are, they are very detrimental to human health.

In addition, since caffeine can increase stomach acid, if you consume it in high doses continuously, it may induce peptic ulcer. For some patients who already suffer from erosive esophagitis and gastroesophageal reflux disease, it will aggravate the condition.

2. Overexcitement

Everyone knows that coffee has the effect of refreshing the mind. This is because coffee contains a large amount of caffeine, a substance that can penetrate the central nervous system and excite the mind, thereby achieving the effect of refreshing the mind. However, you must pay attention to controlling your coffee intake at this time. If you consume too much at one time, it is likely to cause discomfort. If you drink 2-3 cups of coffee continuously at one time, it will cause over-excitement of the central nervous system.

Common symptoms include irritability, nervousness, excitement, insomnia, flushing, increased urination, gastrointestinal disorders, etc. Some people even experience distracted thinking and irregular heartbeat, which can seriously endanger human health.

In addition to the above two points, there is another most serious adverse effect of excessive caffeine, which is fatal harm. You should know that if the caffeine intake exceeds the limit of the human body within a certain period of time, it will directly lead to death. Therefore, although coffee tastes good, it is recommended that friends pay attention to the amount of intake when drinking.
