The effects of light exposure on the cortisol stress response in human males.

Conclusion: Our findings illustrate the crucial role of light intensity and wavelength for the cortisol stress response, in line with current theoretical knowledge of underlying neurobiological mechanisms.Lay Summary: Effects of different light sources were tested on healthy male adults in the morning after a stress test. Their stress responses showed that a bright light exposure increased the stress hormone level greatest compared to dim white, red or blue light sources. Findings point towards the crucial role of light intensity associated with the hormonal stress response. PMID: 32160826 [PubMed - as supplied by publisher]
