Why Does Coffee Make Me Tired Instead of Active?

The caffeine in coffee is a stimulant and consuming increases your heart rate, blood pressure, boosts your energy, and increases your alertness. If you are a night-owl, drinking coffee can help you stay alert and more focused all night long.

Now although caffeine is generally a great energy booster, it can make you feel extremely tired. But why is that? Isn’t it supposed to shoot your energy levels up? Well, there are several explanations to this.

Why Does Coffee Make Me Tired?

1. Coffee Makes You Dehydrated

Have you ever wondered why you’re always running to the bathroom soon after drinking a cup of coffee?

Well, coffee is a diuretic, which means by drinking a lot of it, you are more likely to become dehydrated. So by the time the caffeine wears off, you may find yourself extremely tired and drowsy.

It’s always advisable to drink loads of water before and while drinking coffee to avoid dehydration.

Coffee causes dehydration so one should drink plenty of water.
2. Caffeine Blocks Adenosine Receptors

The caffeine in coffee blocks adenosine receptors in your brain from receiving adenosine.

Adenosine is a neurotransmitter that causes fatigue in the body.

While the stimulant blocks your brain from receiving adenosine, your body continues to produce the neurotransmitter. When the caffeine levels in your body drops, the buildup of adenosine causes extreme physical fatigue and drowsiness.

Too much caffeine is harmless for health.
3. Your Genes are to Blame

Not everyone becomes sleepy or fatigued after drinking coffee, regardless of the amount. Also, not everyone gets dehydrated from drinking coffee. This simply means that coffee affects people in different ways.

Because of this, scientists have confirmed that there are clear genetic variations on how some people metabolize caffeine.

One study conducted on lab rats discovered that one of more recessive genes limit caffeine susceptibility.

4. Sweetened Coffee Gives You a Sugar Crash

Just like with other sugar products, sweetened coffee will most likely give you a sugar crash shortly after drinking it.

The sugar immediately boosts your energy levels since it’s processed much quickly as compared to caffeine. After the sugar is used up, you’re left with very little energy and extreme fatigue.

This could actually mean that the energy boost you’re getting is from sugar, but not caffeine. Thus, it’s advisable to reduce the amount of sugar in your coffee to prevent a sugar crash.

Too much sugar is harmful for body.
5. Caffeine Masks Your Fatigue and Drowsiness Symptoms

The most common reason as to why people drink coffee is to stay alert and awake for longer periods, which is especially beneficial when trying to concentrate on a project or meeting.

However, once the caffeine wears off, you are likely to feel more fatigued and sleepy than you were before consuming the coffee. This is because the stimulant masks off these symptoms.

The excess use of coffee can cause fatigue and drowsiness.
6. Limiting the Effects

One way to reduce fatigue is limiting your caffeine intake. However, cutting back on caffeine abruptly comes with some adverse withdrawal effects such as irritability and severe headaches.
