A new study shows that taking blood pressure medication in sync with your personal chronotype—your body’s natural sleep-wake cycle—can reduce the risk of heart attack. Night owls benefit from evening doses, while early birds benefit from morning doses. The study, involving over 5,300 participants, found that misaligned medication timings increased heart attack risk, especially for night owls taking morning doses. This research suggests a potential paradigm shift in hypertension treatment, emphasizing personalized chronotherapy. However, further clinical trials are needed to confirm these findings before changing current medical practices.
