6 Reasons why caffeine doesn’t affect me or you

6 Reasons why caffeine doesn’t affect me or you

Caffeine. It’s something that’s a real pain for some people. Some people, not everyone. Do those people wonder why caffeine doesn’t affect me?

As you can tell, these can be an advantage or a disadvantage. There are several reasons why caffeine doesn’t affect me or you that much. We will cover 6 reasons more in-depth with you!

Genetical tolerance

When we’re born, we all have our own unique code, DNA, received from our parents and ancestors. Somewhere in our code, there’s something that decides how our body functions.

When you consume caffeine, they react to your adenosine. Adenosine is something that encourages us to sleep. Some people will be able to process caffeine much faster than others. This means that a higher caffeine intake won’t make that much of a difference.

Tolerating caffeine

When you’re consuming the same amount of caffeine on a daily basis, your body will resist it better. You’re going to be less sensitive to the consumed caffeine and you won’t have the desired effect.

Caffeine consumption too high

Your body becomes adapted to circumstances and builds up resistance.

When you drink, on a regular basis, too much coffee, you’ll consume a lot of caffeine. When you’re used to something, consuming less than you used to consume won’t give you a boost at all.

The average daily regular caffeine intake is about 400 milligrams (mg).

We don’t advise you to consume a lot of coffee as it can come with some disadvantages. Coffee can be bad for you if you overconsume it.

You can get your biological rhythm or flow disturbed. When you’re more and more deprived of your sleep, you can start to get stressed, suffer from anxiety and get more frustrated, overreacting to people you love.

Always review your coffee, if you’re trying new things, please note that you can only process a certain amount of caffeine.

You can try alternatives like low acid coffees, cold brew, or decaf espresso. That way, you’ll drink your coffee daily and have a lower caffeine intake, allowing you to get that boost when you need it.

Caffeine consumption too low

This one is opposed to the point before. Every human being is different. Some people are older, weigh more, are naturally more resistant to caffeine, and so on.

When you’re realizing that caffeine isn’t working as much, you can try to consume more coffee or coffee with higher amounts of caffeine.

Always keep the amount of your caffeine intake tracked as this can be beneficial for you in the long run.

You could also go for some stronger coffees that are known for their higher caffeine ratio. Mostly these will be coffee blends that exist for the most part out of Robusta beans.

Not sleeping enough

The amount of sleep is very important for your health in general. We’re not talking about a sudden lack of sleep but more of a structural lack of sleep (at least a few days).

When you feel tired and ready to sleep, this means your body has adequate adenosine. When you’re drinking coffee – and thus caffeine – you’ll feel more alert instead of sleeping because the caffeine reacts to adenosine.

Luckily, our body will make more adenosine, the longer we’re not sleeping enough. This means there will be more adenosine and the caffeine won’t be able to “battle” them all, so you’re thinking that your daily caffeine intake isn’t working that well.

You could consume lots more coffee but that’s not something we advise you to do.

Changing your coffee beans

Another logical reason is what kind of coffee beans you’re using. These coffee beans are chosen after you’ve selected your desired brewing method.

Arabica beans contain less caffeine when compared to Robusta beans. Robusta beans are more used to make instant coffees, because of the higher amount of caffeine (and other reasons like they’re more resistant to the changer weather).

Some brewing methods are not beneficial for caffeine levels. When you’re cold brewing, you’ll have way less caffeine compared to hot brewing on the same coffee grounds. When you’re using a stronger filter when brewing drip or pour over, it will also filter more of the caffeine.


There’s always a great reason to get yourself a cup of coffee. This doesn’t mean you should overconsume coffee at all. It’s important to balance because caffeine can have a good effect, but you should be able to get it when you need that boost. We’ve equipped you with 6 possible reasons why that boost isn’t coming!

As always: enjoy your coffee!
