This Is the Worst Time of Day to Drink Coffee - My Morning Cup

This Is the Worst Time of Day to Drink Coffee - My Morning Cup
From The Kitchn - October 11, 2017

If the best part of waking up is Folgers in your cup, then you are starting your day completely wrong. With apologies to the country's best-selling ground coffee, some dietitians are now suggesting that none of us should be stumbling straight out of bed and directly to the coffee potregardless of what brand we are brewing.

According to Laura Cipullo, registered dietician and best-selling author, getting our caffeine fix first thing could cause us to feel nervous and jittery by mid-morning, then like we need a nap before lunch. And the culprit is not the coffee itself (or even the caffeine), but one of our own hormones: cortisol.

Research shows that cortisol levels spike shortly after waking, then fall, then peak again at midday. After that, they drop, peaking again in the early eveningconveniently, about the time that we are all trying to make our way home from the office.

Since our levels of cortisol (the so-called "stress hormone") are highest in the mornings, Cipullo suggests that adding caffeine might make us feel extra rattled.

Neuroscientist Steven Miller agrees. If you are "drinking caffeine at a time when your cortisol concentration in the blood is at its peak, you probably should not be drinking it," he wrote. Not only can drinking your daily cuppa first thing make you feel jittery, but over time it can also make the caffeine less effective at delivering that much-needed boost.
