coffeeCoffee is a great thing.  It is also a powerful thing. So, to best use the marvelous gift that God has given us, let’s learn about when coffee is the most effective.

So, not to get too scientific, but your body produces this thing called cortisol. It is a stress hormone and is associated with your alertness levels. So, at the times that your cortisol levels are high, drinking coffee will have no added effect, because your alertness levels are at their peak. However, when your cortisol levels fall, coffee can serve as a much needed reinforcement.

Here are the times where the body’s cortisol levels are at their peak (meaning coffee will have no added effect):

Between 8-9 AM

Noon – 1PM

5:30 – 6:30 PM


There is also a time where coffee serves as the most effective and that is from 9:30 – 11:30AM.

Now, the Library will have coffee during finals week, and it will be when your cortisol levels are low, so be sure to come on out and enjoy the free coffee to help you find that motivation to finish the semester!
