Studies demonstrate that people exposed to bright morning light show more robust cortisol awakening responses and better-regulated daily cortisol patterns compared to those with dim light exposure. This suggests that morning light is not just important for circadian timing but also plays a crucial role in optimizing stress hormone function and resilience.

These immediate effects occur alongside longer-term circadian benefits, making morning light exposure a powerful tool for optimizing both acute alertness and daily rhythm regulation.
