Caffeine is one of the most widely used active substances in the world. It is found in a variety of foods and drinks, including coffee, tea, soda, chocolate, and energy drinks. Caffeine works by stimulating the central nervous system and increasing alertness.

Caffeine does this by blocking adenosine receptors in your brain. Adenosine makes you sleepy—and blocking those receptors means that less adenosine can reach its target. That leaves more of your neurotransmitters (chemicals that send signals between nerve cells) available to communicate with each other. This helps keep you awake!

History of Caffeine

Caffeine is a naturally occurring stimulant that acts as a central nervous system (CNS) stimulant. It can be found in the leaves, seeds and fruit of some plants where it acts as a natural pesticide that paralyzes insects feeding on the plants.

In 1819, German chemist Friedlieb Ferdinand Runge discovered caffeine from coffee when he isolated it from roasted coffee beans.

In 1820, French pharmacist Senebier suggested that caffeine could help migraine sufferers and by 1827 doctors had begun prescribing caffeine in migraine treatment.

Benefits of Caffeine

Caffeine is a natural stimulant that has been shown to improve brain function, including alertness, focus and concentration. It also helps increase energy levels and athletic performance.

Caffeine may also have positive effects on memory and mood. Caffeine can increase dopamine, serotonin and norepinephrine levels in the brain. Dopamine is a neurotransmitter that plays a role in pleasure and reward-driven behavior. It's also involved in attention, memory and motivation. Serotonin is another neurotransmitter that helps regulate emotional responses like those associated with stress or depression. Norepinephrine is yet another type of neurotransmitter linked to mood regulation; it's also associated with wakefulness and energy levels, according to the Mayo Clinic. Because all three play such important roles in regulating your moods — either positively or negatively — consuming caffeine can have a significant impact on how you feel throughout the day (and even after).

Research suggests that caffeine can reduce the risk of type 2 diabetes by up to 24% in women who consume at least one cup of coffee per day, compared with non-coffee drinkers. Caffeine may also help lower the risk of Alzheimer's disease and cognitive decline. Several studies have found that caffeine intake may reduce your chances of developing dementia, especially as you age.

Caffeine also has antioxidant properties, which can help fight free radicals in your body (free radicals are often associated with aging). Similarly, caffeine is a vasodilator that causes blood vessels to relax and expand, allowing for more oxygenated blood to flow through your brain. This could explain why some research shows that drinking coffee can improve short-term memory. If there is enough oxygenated blood flowing through your brain cells at any given time, then the neurons will be able to function properly and form new memories.

Safety of Caffeine

The World Health Organization (WHO) has concluded that “the acute effects of caffeine are well documented, generally mild and transient," though they did note that "caution should be exercised in people with cardiovascular disease and women who are pregnant or breastfeeding."

In moderation, caffeine is safe for most people. According to a study published in the Journal of Food Science, the caffeine content of coffee can vary widely depending on its preparation and brewing method. In general, though, one cup (120 ml) of brewed coffee contains more than 80 mg of caffeine—enough to get you through the morning, but far from causing any serious side effects.

Caffeine can cause adverse health effects if consumed in excess. Heavy consumption may lead to insomnia, headaches and irritability. High doses have also been linked with heart problems as well as elevated blood pressure and anxiety disorders.


Caffeine is a chemical substance that has many benefits for your health. It can help improve athletic performance, reduce stress levels, and even increase your lifespan!
