Coffee is the most popular drink in Germany. According to the German Coffee Association, our consumption has risen continuously in recent years. The current average consists of four cups a day. Whether it’s the morning coffee that gets us out of bed or the caffeinated soft drink in the afternoon – caffeine is an integral part of our everyday lives. But what exactly happens in our bodies when we consume caffeine
1. The absorption:
As soon as we consume caffeine whether it is through coffee, tea or other drinks, it is quickly absorbed by our gastrointestinal tract. Within around 15 to 45 minutes, it reaches its maximum level in our bloodstream. This is the moment when we feel the famous “caffeine kick”.
2. The effect:
Caffeine is a stimulant which means it stimulates our central nervous system. It blocks the effect of a neurotransmitter called adenosine which normally signals tiredness. This makes us feel more awake and alert. But be careful: too much caffeine can also lead to tremors, nervousness and a racing heart.
3. The side effects:
Even though caffeine gives us a short-term energy boost, it can have side effects. Excessive consumption can lead to sleep problems as caffeine can affect the quality of sleep. It can also lead to stomach problems such as heartburn or gastrointestinal discomfort. Therefore it is important to keep an eye on your caffeine intake and not overdo it.
4. Addiction:
Caffeine can also be addictive. If we consume caffeine regularly, our body gets used to it and develops a tolerance to the stimulating effect. This means that we need more and more caffeine to achieve the same effect. Suddenly cutting it out can lead to withdrawal symptoms such as headaches, irritability and fatigue.
5. The benefits:
When consumed in moderate amounts, caffeine also has health benefits for our bodies. Studies have shown that caffeine can improve cognitive function, elevate mood and even reduce the risk of some diseases such as Parkinson’s and Alzheimer’s. Coffee is also rich in antioxidants which can protect our cells from damage, boost the immune system and reduce the risk of various diseases.
6. The right dosage:
“The dose makes the poison” or in this case “The right dosage is key to success”. The recommended daily upper limit for caffeine is around 400 milligrams which is roughly equivalent to four cups of coffee. It is important to keep an eye on your caffeine consumption and watch out for possible side effects. Everyone reacts differently to caffeine, so listen to your body and adjust your consumption accordingly.
Conclusion:
Caffeine is undoubtedly a fascinating substance with a variety of effects on our bodies. From a quick energy boost to long-term health benefits, the effects of caffeine are many and varied. But as with everything in life, it’s all about finding the right balance. So enjoy your coffee or black tea, but don’t overdo it. Your body will be grateful!
