Neurologists advise on optimal timing for morning coffee consumption

Neurologists suggest that the timing of morning coffee consumption is critical for brain health and sustained energy levels. Consuming caffeine immediately upon waking can disrupt the body's natural circadian dynamics, specifically interfering with the morning surge of cortisol and noradrenaline that naturally promotes alertness.

Caffeine works by blocking adenosine, a chemical signal for fatigue. However, consuming it too early can lead to increased irritability, decreased focus, and a significant energy crash once the effects wear off. This cycle often leads to higher caffeine tolerance and a dependency on additional doses to combat afternoon fatigue.

Experts recommend waiting 60 to 120 minutes after waking before having the first cup. This allows the natural cortisol rise to subside, resulting in a cleaner, more long-lasting effect. A moderate dose of 80–150 mg is typically suggested for optimal results.
