Caffeine: benefits, effects and impact on your health

Caffeine is a common substance that we encounter daily in coffee, tea, soft drinks and other products. It is known for its stimulating effect and is often used to combat fatigue. But how exactly does caffeine work, what does it do in your body, and how can you use it wisely?

In this blog you will discover what caffeine does, how it affects your performance and how you can prevent fatigue in the long term.

What does caffeine do?

Caffeine is a natural stimulant found in coffee beans, tea leaves, cocoa beans, and guarana. It works by blocking adenosine receptors in your brain, making you feel less tired and increasing your energy levels.

The battle for alertness, how does it work?

Adenosine is a natural substance in your brain that builds up throughout the day and is responsible for the feeling of fatigue. The more adenosine builds up, the sleepier you become. Adenosine is broken down during sleep, allowing you to wake up feeling refreshed and restored.

Caffeine works by temporarily blocking the action of adenosine. This makes you more alert and energetic. This is why coffee is often used to combat fatigue.
