Caffeine is a natural stimulant found in the seeds, leaves and fruits of certain plants. It is produced by these plants as a defense against herbivores and insects that might eat them.
Caffeine has been used for millennia by humans in the form of stimulant drinks.
Coffee, tea and cocoa are the most common sources of caffeine in the human diet.
Coffee originated in Ethiopia and was introduced to Europe in the 17th century.
Tea originated in China and was introduced to Europe in the 18th century.
Cocoa is native to Central America and has been used by the Mayans and Aztecs for centuries.
Today, caffeine is produced from a variety of sources and is used in many food and drink products, including energy drinks and dietary supplements.
Caffeine works by blocking the action of an enzyme called adenosine in the brain. Adenosine is a neurotransmitter that helps regulate wakefulness and sleep, and by blocking its action, caffeine can help increase alertness and concentration.
When you consume caffeine, it quickly passes through the blood and goes to the brain. Once there, it blocks the action of adenosine and stimulates the production of dopamine, another neurotransmitter that helps with alertness and motivation.
Caffeine can also increase heart rate and blood pressure, and can cause side effects such as insomnia, anxiety, and nervousness in some people. It is important to consume caffeine in moderation and to take it into account.
