QUESTION: How long does it take for coffee to kick in? I have been working a lot of late shifts lately and it’s hard to get up the next day. – Wade F
ANSWER: To feel the effects of the caffeine from a cup of coffee, it generally takes about 10 minutes until you can feel the difference. But from there, the effects continue to grow and you’ll probably reach the peak of the amount of caffeine in your bloodstream within an hour, according to MedLine Plus. At that point, you can generally feel the effects of caffeine for the next 4 to 6 hours before it wears off.
So give yourself at least 10 minutes for the coffee to start to kick in, and once you feel it kicking in you’ll know you’re on your way to peak caffeinated awesomeness over the next hour.
Drinking more coffee will increase the amount of caffeine in your bloodstream, but be careful not to overdo it. Drinking too much can upset your stomach or leave you feeling jittery and sick from too much caffeine. If you regularly drink a lot of coffee, you’ll also build a tolerance to caffeine as well as start a dependency. If you’ve ever tried to stop drinking coffee when you normally drink several cups a day, you’ll know exactly what I’m talking about. Headaches.
