Optimal Morning Coffee Time for Maximum Mood and Alertness

Research shows that drinking coffee in the morning boosts happiness, enthusiasm, and alertness by blocking adenosine receptors and increasing dopamine activity, with the strongest effects within two and a half hours of waking. The mood lift is consistent across different mental health and caffeine habits, and is influenced by tiredness and social settings, but not by long-term stress or anxiety. Moderation is recommended to avoid sleep disturbances and dependence.
