Always Feel Tired After Drinking Coffee? This is the Cause

Jakarta –

The caffeine in coffee acts as a stimulant which can cause various effects in the body. One of them, feeling tired after consuming coffee. Here’s the explanation!

Coffee is synonymous with caffeine content. Caffeine is a stimulant compound that has a direct effect on the central nervous system. Caffeine works by blocking adenosine receptors.

In these conditions, caffeine will have various effects on the body. However, the effects can differ in each individual. For coffee lovers, the effect may be to increase energy.

However, for those who are intolerant to caffeine it can have uncomfortable effects. Like feeling tired and sleepy after drinking coffee. This condition occurs due to several factors.

Quoted from various sources, here is the explanation!

1. Adenosine in the brain is blocked

Quoted from News Medical (25/10/24) the reason the body becomes tired after drinking coffee is because caffeine blocks adenosine receptors in the brain.

Adenosine is a brain chemical that influences sleep patterns. Adenosine levels will increase when you are awake and decrease when you sleep.

In this condition, caffeine blocks the brain’s response to adenosine, thereby keeping you focused and alert. And caffeine doesn’t stop the production of these compounds.

This means that when the effects of caffeine wear off, there will be a buildup of adenosine which ultimately causes the body to become tired and weak.

2. Caffeine causes insulin resistance

Insulin resistance is a condition where the body’s cells cannot regulate blood sugar levels effectively. And for some people, caffeine can have this effect.

If blood sugar levels are irregular, it can cause the body to become more sensitive to sugar or carbohydrates contained in food and drinks.

That way, you will feel a temporary spike in blood sugar in the body. Meanwhile, the body processes sugar much faster than caffeine.

This condition can cause a decrease in energy and feeling tired after drinking coffee. Especially if blood sugar does not reach clinically high levels.
