4 symptoms of excessive coffee drinking



Caffeine is generally known to increase activity and alertness. It works by blocking the effects of adenosine, a chemical in the brain that makes you feel tired. At the same time, it triggers the release of adrenaline, associated with increased energy. However, at higher doses these effects can be more pronounced, leading to anxiety and nervousness.

In most people, a daily intake of more than 1,000 mg of caffeine per day has been reported to cause nervousness and feelings that lead to anxiety.

If you notice that you often feel jittery. Try to focus on the amount of caffeine you take in during the day. There may be a real cause here.


Many people drink coffee for one reason in particular. Caffeine helps them stay awake longer and gives them the energy they lack. On the other hand, too much caffeine can harm your sleep quality. Studies have shown that higher caffeine intake increases the time it takes to fall asleep. It can also shorten the overall sleep time and thus interfere with sleep quality. Researchers found that if caffeine was obtained 6 hours before sleep, the amount of sleep was disrupted over an hour. Caffeine slows down the production of the hormone melatonin, which affects our sleep and its quality. If we are deficient in .melatonin, we have a problem with insomnia. People who are more sensitive to caffeine should skip coffee in the afternoon.


Many people don't do well with a morning cup of coffee on an empty stomach. The laxative effect of coffee is due to the release of gastrin. This is a hormone that the stomach produces and which speeds up activity in the colon. In addition, decaffeinated coffee has been shown to produce similar symptoms.

Caffeine itself stimulates bowel movements by increasing peristalsis, the contractions that move food through your digestive tract. Given this effect, it's not surprising that large doses of caffeine can lead to constipation or diarrhea in some people.


If you feel more thirsty when drinking coffee, there is a definite connection. According to a French study, caffeine has a diuretic effect that can affect hydration. However, you would have to drink a lot of coffee to get to this point, as another study shows that moderate caffeine consumption (2 to 3 cups a day) does not affect the risk of dehydration. This means that if you are dehydrated from coffee, you are already drinking it in really large quantities. So you'd better replace a cup of coffee with a glass of water sometime.


Coffee can help in some moments, but when consumed excessively, it can do harm. It's up to you whether you make coffee your friend or your enemy. Focus on the problems you are currently facing and think about whether it is because of coffee. Better said, caffeine.

If you know you should cut down on coffee, try replacing it with adecaffeinated version, for example . Or try drinking teas. But beware, white, black and green tea also contain caffeine.
