Science’s Tip For Coffee Drinkers

I haven’t been much of a coffee drinker until recently after high school and the start of university. It really makes a difference in doing assignments and focusing during it. There’s also such joy of this drink in the morning, having a warm cup as the morning sun greets us before school or work. But does the morning really make it the best time for our caffeine companion? Not necessarily.

I read a post on a blog by Ryoko Iwata who is a coffee enthusiast and gained a new revelation on this habit. She based her post on Steve Miller’s blog and his musing about it. Our body naturally has a rhythm and this is called our Circadian Clock. When your stomach rumbles and you’re craving for something to eat, that’s guided by the circadian clock. So does, waking up in the morning. During this 24 hour cycle, our body produces a hormone called cortisol that plays a part in getting us awake, alert, and out of bed (which can take a while for me, haha.) which happens between 8 to 9 am in the morning. Therefore, our body is naturally making itself caffeinated just like what coffee does and also stimulated to start the day. If we drink too much of coffee at this time where our levels of cortisol are at its highest, our body will only become used to the “buzz” we get from caffeine – which helps us to be awake and focused. In other words, there wouldn’t really be any use of drinking coffee as its effects are lessened.

You might be thinking this doesn’t speak to you as some coffee-goers love to experience and explore the different tastes of coffee from around the world, which I’m starting to be introduced to especially coffee from my own country. However, for professionals and high school or university students like me, the boost or buzz from coffee do help us in being more alert when needed, come up and execute creative ideas and staying focused at what is at hand. As a result, I do find being in a coffeeshop is a much better environment for studying.  So, we can take note of the time where our cortisol level starts to drop, which is between 9.30 to 11.30 am and 13.30 to 15.30 in the afternoon.

But what if you’re one of those early birds? Here’s what an article got from Steve Miller’s study; What about those of you who wake up insanely early? According to the research, “Although the release of cortisol is mostly controlled by sunlight, levels of cortisol increase by about 50% upon awakening.” So even if you get up a 5 a.m. you aren’t off the hook completely. Science says you still don’t need your first cup of coffee until at least an hour after you get up. (

Coffee is such an insanely rich and soulful drink that I find so beneficial to be knowledgeable about. It makes us happy and a little bit nostalgic at times. It also has more benefits that we thought we knew and I hope you’ll find this useful because it’s definitely a tip that I’ll include in my coffee routine.
