Germany's coffee obsession grows as caffeine intake hits a decade high
Caffeine remains the world's most widely consumed psychoactive substance, found in everyday drinks like coffee, tea, and cocoa. While it offers short-term benefits such as improved focus and alertness, its effects vary depending on consumption habits and individual health. Recent data also shows a steady rise in coffee drinking across Germany over the past decade.
Most people consume caffeine through beverages, but it also appears in foods like baked goods, ice cream, sweets, and energy drinks. The substance works by blocking adenosine receptors in the brain, temporarily delaying feelings of tiredness. However, its stimulating effects only become noticeable when someone is already sleep-deprived—and these benefits fade after four days of poor sleep.
The European Food Safety Authority advises that healthy adults can safely consume up to 200 milligrams of caffeine at once, or 400 milligrams spread across the day. Exceeding these amounts may lead to side effects such as nervousness, insomnia, sweating, or an increased heart rate. Long-term overconsumption has also been linked to cardiovascular issues.
In Germany, coffee consumption has gradually increased over the last ten years. Average daily intake rose from roughly 8.1 litres per person annually (about 22 grams) in 2015 to 8.5 litres (around 23 grams) by 2025. Trends like premium coffee, home-brewing during the COVID-19 pandemic, and higher prices for alternatives like tea have contributed to this shift. Currently, the average German drinks about 164 litres of coffee per year—17 litres more than two decades ago.
Despite its widespread use, caffeine does not pose a high addiction risk. Yet, those who abruptly stop after daily consumption may experience withdrawal symptoms, including headaches, drowsiness, and irritability.
Caffeine's popularity continues to grow, particularly in Germany, where coffee remains a daily staple. While moderate intake is generally safe, excessive consumption can lead to health complications. Understanding its effects helps consumers balance its benefits with potential risks.
