Time Your Caffeine Intake to Maximize Effect and Avoid Building a Tolerance


I don’t know about you, but I love my morning coffee. I always have a huge cup of water at my desk, and love a cup of tea … but there is just something about that morning coffee. Generally I have already gone for my run and showered, and am settling in for the day. Doesn’t matter if it is winter, spring, summer or fall … there is nothing like it.

But if you had a coffee and are still ‘not feeling it’, new research from Neuroscience DC (reported in PopSci) has a word for you: chronopharmacology

According to the report, to get the biggest bang from your coffee, timing is everything:

your cortisol levels peak between 8 and 9 AM, there are a few other times where–on average–blood levels peak again and are between noon to 1 PM, and between 5:30 to 6:30 PM. In the morning then, your coffee will probably be the most effective if you enjoy it between 9:30 AM and 11:30 AM, when your cortisol levels are dropping before the next spike.

There is actually a load of information, both fun and technical, in the article – and some cool links as well!

When do you drink your coffee? Do you have issues with caffeine if you drink later in the day (Lisa can’t sleep if she has caffeinated coffee after dinner)?

  1. Actually, Sammy if you take a step back in time, it seems like between 6-7 is the previous cycle low point. So if you are a two cup person then having one between 6-7 and the other after 9:30 actually makes sense.

    Not that any of that would change my habits anyway! 🙂
