Disrupted sleep-wake cycle
Detailed Analysis
Taking caffeine and melatonin together can disrupt the body's natural sleep-wake cycle. Caffeine can delay the release of melatonin, making it harder to fall asleep. This interaction may affect the quality of sleep and alertness. Caffeine delays the human circadian melatonin rhythm through an adenosine receptor/cyclic adenosine monophosphate (AMP)–dependent mechanism. This means that caffeine blocks the action of adenosine, a chemical that helps regulate sleep, which in turn affects melatonin production. As a result, melatonin release is delayed, impacting the body's natural sleep-wake cycle.
