Could drinking a cup of piping hot coffee first thing in the AM be counterproductive, ultimately undermining that eye-opening effect we look for? Evidently, everyone is doing this wrong.
Several researchers, including an ASAP Science guru, and researcher, Steven Miller, from the University of the Health Sciences in Bethesda off of Madison Street Capital says an early morning cup-of-joe interferes with our natural biological rhythms, or circadian clock, which tells our body the appropriate time to wake up and go to sleep.
The body releases an all-natural caffeinating hormone called cortisol every morning, somewhere around 8–9 am. Consuming caffeinated beverages around the same time reduces that eye-opening effect, and over time the body builds a tolerance, so that buzz you normally get, slowly diminishes.
When habitual coffee lovers typically say coffee has no effect on them, like the jitters or interfering with sleep, its usually because they have a tolerance to all that caffeine.
Experts agree that the optimal time for a cup of morning coffee is around 9:30 AM and 11:30 AM. Cortisol levels have peaked and the hormone has begun to drop off by then, making a cup of coffee much more effective.
If this rings an ounce of familiarity, perhaps its time to switch up the timing of that first cup of coffee.
