Coffee and effect of caffeine

Coffee and effect of caffeine –
Who first started using coffee? Was coffee first used as food or medicine? Or maybe as a means of enjoyment? No one can reliably answer this question, because the beginnings are shrouded in secrecy. Although there is no reliable data, there is a story that coffee as a wild plant, shrub and tree, was discovered in Africa. It is also known that it was first used as a beverage in Arabia. It is unthinkable for many to start the day without a cup of invigorating coffee, an invigorating and awakening beverage. What is the secret of coffee? The most famous and most important ingredient in coffee is caffeine, which is absorbed or passed directly into the blood, where it stays for up to 4 hours. Caffeine stimulates the central nervous system, increases alertness, attention, mood and concentration, and most often for all that, in short, it eliminates fatigue.

Namely, the effect of caffeine from coffee reaches its peak in five to 10 minutes, sharply increases the energy level, and disappears after 30 minutes, while caffeine from tea more slowly reaches its maximum effect after 40 to 45 minutes and disappears after 70 minutes. Yet coffee is coffee. Only she can awaken all the senses with her scent and improve her mood in an instant. The average cup of coffee contains 100 to 150 mg of caffeine.
Most doctors agree that less than five cups of coffee a day has no negative effects on the cardiovascular system. However, those who have experienced a heart attack must pay attention to the daily dose. Excess increases the heart rate, which can lead to arrhythmia. People with severe heart disorders are advised to give up coffee or drink decaffeinated coffee.
