What Is Caffeine?

how does caffeine affect the body


Caffeine is a popular and addictive natural stimulant that is usually found in tea, coffee, soft drinks, and also in cacao plants. The main property of a caffeinated substance is that it activates your brain and central nervous system to avoid tiredness. Most people consume it to stay vigilant and alert during work.

These caffeinated products date back many thousands of years, when in 2737 B.C. at Kenya brewed tea was found. Moreover, coffee was accidentally discovered by an Ethiopian shepherd whose goats used to be hyperactive after gazing at cacao plants. People used to rely on tea and coffee for most years until in the late 1800s, brands introduced caffeinated drinks in the market.

The number keeps on increasing with every passing day with a huge number of coffee places, tea stalls, and energy drinks being sold around the world.


How It Works

Before going into the effects and impacts of caffeine, first you need to figure out about its working procedure on your body. When you consume any caffeinated product, it is immediately absorbed from the gut and added into blood. Since your blood is circulating to all the different organs, caffeine also surrounds your body from liver to various other compounds, having a major impact on the functionality of major organs.

Moreover, the main target of caffeine is your brain and nervous system. It is responsible for terminating the effects of a neurotransmitter called adenosine. In normal circumstances, these neurotransmitters relax your brain because of which you feel tired. The adenosine is at its lowest when you wake up and gradually builds up throughout the day till you don’t have any energy to stay awake.

Now for those who want to stay up late for any reason, caffeine helps to stay up to connect the deactivated adenosine receptors in your brain. This reverses the impact of adenosine and reduces the feeling of tiredness and fatigue. You’ll also find yourself being more pumped up because of higher adrenaline levels and increased dopamine and norepinephrine activities.

This is the reason why caffeine is known as the psychoactive drug that exerts its effects rapidly in the human body. For instance, if we drink one cup of coffee it’ll reach your bloodstream within 20 minutes and activate its full potential within an hour.

  • Energy drinks have 50-160 miligrams
  • Yerba mate has 65-130 miligrams
  • Coffee has 102-200 miligrams
  • Espresso 240-720 miligrams

Even decaf coffee isn’t free from caffeine and also has 3 to 12 milligrams. Moreover, depending on the type of chocolate, the caffeine ratio is higher with milk chocolate standing at the least and dark chocolate at highest.
