How Long Does Coffee’s Caffeine Last?

In the words of Lorelai Gilmore, “I can’t stop drinking the coffee. I stop drinking the coffee, I stop doing the standing and the walking and the words putting into sentence doing.” You don’t have to be a Gilmore girl to love coffee or its caffeinated benefits. But, just how long does the caffeine last? 

If you enjoy a morning cup of joe but find yourself feeling sluggish in the middle of the day, it might have to do with the caffeine from your coffee starting to work its way out of your system.

How long the caffeine from a cup of coffee lasts actually depends on a variety of factors, including the strength of the coffee and how much you consume.

It’s also important to note that caffeine has something called a “half-life” that lasts up to five hours.

Basically, that means about five hours after drinking a cup of coffee, you’ll have half of the caffeine from it left in your body.

A medium-roast coffee can offer a perfect amount of caffeine without being too bold or bitter.

As the caffeine works its way through your system, you’re likely to feel the strongest effects of it sooner, rather than later. Within 30-60 minutes after you’ve had your coffee, you’ll probably feel the initial jolt of caffeine that can make you feel more awake and alert.

Over the next few hours, those feelings will start to reduce. You’ll probably feel less “jittery” but you’ll still be able to enjoy the positive energy effects from the slow release of the caffeine through your body.

Some people are more sensitive to caffeine than others. If you find that you’re slowing down in the afternoon, try not to reach for another cup of coffee right away, as it might end up affecting your sleep later. Instead, do some stretching, take a short walk, or eat something to get a quick energy boost.
