Cortisol is the infamous hormone you release when you’re stressed. In high doses it inhibits brain function, slows metabolism, breaks down muscle, and increases blood pressure. Have you ever felt panicked before a public speech and forgotten everything you were going to say? That’s what a big bump in cortisol feels like. And if you’re looking for stress relief, lowering cortisol helps.
Cortisol isn’t all bad, though. In fact, it’s necessary for you to function. Cortisol peaks in the morning, helping to wake you up, and it can be a useful as an indicator of strain, letting you know when to slow down or stop something that’s stressing you out. Cortisol also decreases inflammation – that’s part of the reason your body releases it in response to, for example, a workout that tears your muscle tissue.
Low cortisol is an issue, too. Insufficient cortisol can leave you feeling tired, emotional, and anxious. As long as you avoid chronically elevated or depleted cortisol you can make the little hormone work to your advantage.
A common argument against drinking coffee is that it triggers cortisol release, but (forgive us for getting nitpicky) that may not be true. Caffeine definitely triggers cortisol release. In fact, the increase in cortisol is part of the reason caffeine makes you feel more alert.
Remember a few paragraphs ago, when we were talking about how you build a tolerance to some of caffeine’s effects but not others? Cortisol release is one of the effects to which you build tolerance. If you only take caffeine now and then, it causes a big boost in cortisol. But if you get caffeine daily (by drinking coffee every morning, for example) your body tempers the cortisol response. You still release cortisol, but not enough to worry about unless your cortisol is already out of whack.
Does coffee itself (separate from caffeine) cause cortisol release? Mycotoxins do, at least in mice, and they cause inflammation (a common trigger of cortisol release) in humans. It’s difficult to say whether mold-free coffee increases cortisol.
Regardless, studies suggest that cortisol release from caffeine is mild if you drink it daily. For most of us, that little bump shouldn’t be a problem.
