How many of us have a cup of coffee in hand within just a few minutes of getting out of bed? And let’s be honest, the only reason we wait that long is because scientists have yet to develop a way for us to drink coffee in our sleep. (When a caffeine-infused bed is invented, we'll be sure to add it to our best mattress guide.)
However, an 8am espresso might not be the solution to shaking off sleepiness. Rather than turning your alarm off with one hand and reaching for the coffee pot with the other, it might be better to wait at least an hour before drinking something caffeinated.
