a single 1-minute light pulse rapidly resets melatonin production at the cellular level
A single 1-minute light pulse at night causes a rapid decline in pineal N-acetyltransferase (NAT) activity with a half-life of less than 5 minutes, effectively resetting the circadian rhythm in melatonin production.
What this means for you
Melatonin governs your sleep-wake cycle, and even brief light exposure can shift its rhythm within minutes. Understanding how quickly your body responds to light helps explain why light-based wellness sessions may support more consistent sleep timing and a more balanced internal clock.
