The morning coffee ritual is a daily staple for many—a necessity that energizes us, sharpens focus, and delights the senses. Whether you prefer it short and strong or long and milky, its psychological pull often gets us out of bed through that morning fog. With benefits like supporting weight management and easing migraines, coffee has plenty going for it. But timing matters. Neuroscience doctoral student Steven L. Miller explains the key mistake to avoid with your morning brew.
To optimize coffee's effects, consider cortisol levels in your blood. This hormone influences how caffeine performs: it's ineffective during cortisol peaks but shines when levels dip. The ideal windows are coffee breaks from 9:30 a.m. to 11:30 a.m. and 1:30 p.m. to 5 p.m.. Skip it at breakfast (8 a.m. to 9 a.m.), lunch (11:30 a.m. to 1:30 p.m.), or late afternoon (5:30 p.m. to 6:30 p.m.).
Dubbed the "stress hormone," cortisol fuels your body during physical activity, stress, or upon waking. Adding caffeine then is redundant and can lead to tolerance, diminishing long-term benefits.
