Increased heart rate, blood pressure, altered heart rhythm (called atrial fibrillation) which may lead to blood clots in heart.

Not having a set timing for drinking coffee can make it harder to fall sleep, decrease the duration of our sleep, disrupt sleep stages and cause restless night's sleep  (Dawood, 2022)
