The Scientifically Best Time to Drink Your Coffee
Neuroscience PhD student Steven Miller explains that in the mornings (between the hours of 8 am and 9 am) our cortisol levels are at their highest. Cortisol isn't just the "
So if we drink coffee at the same time our alertness is already at its peak, we're wasting the potential alertness boost we get from the caffeine:
One of the key principles of pharmacology is use a drug when it is needed (although I'm sure some scientists might argue that caffeine is always needed). Otherwise, we can develop tolerance to a drug administered at the same dose. In other words, the same cup of morning coffee will become less effective
The most effective time to have a cup of joe, Miller says, is between 9:30 am and 11:30 am . (Between noon and 1 pm and between 5:30 pm and 6:30 pm are other times cortisol levels rise, so you might want to avoid drinking coffee during those hours.)
If you're going to drink more than one cup of coffee, though, a cup or less every hour
