Morning Light Exposure Affects Cortisol Levels and Stress Response
How Does Morning Light Exposure Affect Your Stress Hormone Levels?
Morning light exposure significantly influences cortisol patterns and stress hormone regulation, with research showing that bright light enhances the natural morning cortisol rise and helps optimize daily stress hormone rhythms. 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.
