Our daily routine will not be complete without our morning cup of coffee. Coffee has become part of the culture we drink coffee not just because it’s delicious, but the main reason is we need coffee to wake up our brain and to boost our energy.

We already know the power of caffeine to our body where it raises the heart rate and blood pressure to boosting energy levels and moods.

But how long does caffeine take action to our body after it kicks in?

Well, the effects of coffee depend on each person, as with any drug the way your body reacts depends on how quickly it metabolizes the caffeine.

Usually, it takes 15 to 45 minutes for caffeine levels to peak in your blood. During this stage of time, your heart rate, and blood pressure rise, and that’s what gives the awake and energetic feeling.

But when the coffee reaches the liver where it quickly filters out the caffeine, the effects won’t last all day.

Caffeine has a maximum of a half-life of about five hours.

An average cup of coffee contains 40mg of caffeine, so after five hours only 20mg will be left in your system. And people who drink more than 3 cups of coffee like it’s your lifeline at work, your body will build up its caffeine tolerance.

So if you used to drink more than three cups of coffee a day, then you might barely notice when the caffeine hits you. But if you drink coffee ones in a while, the effects may last longer.

The impact of caffeine on our body depends on the amount of coffee you consume a day, and also depends on your weight and age. So if you drink several coffees in an hour, the caffeine effect will be fairly intense. But on the other side if you drink decaffeinated coffee, then don’t expect to get the caffeine buzz you are looking for.

Also, if you are overweight, you may find that you need more caffeine before you start feeling the effects.

As most of coffee health articles say and even health professionals, too much caffeine is not good. Having too much caffeine can lead us to caffeine resistance, or we might experience sleepless nights, or trouble falling asleep because of too much coffee intake.

In conclusion, caffeine can last in our system the whole day even once the high has passed, so if you have experienced a hard time sleeping try not to drink your coffee in the early afternoon so that the caffeine effects weary off in your system by the time you go to bed.
