The Effects of Red and Blue Lights on Circadian Variations in Cortisol, Alpha Amylase, and Melatonin


The primary purpose of the present study was to expand our understanding of the impact of light exposures on the endocrine and autonomic systems as measured by acute cortisol, alpha amylase, and melatonin responses. We utilized exposures from narrowband long-wavelength (red) and from narrow-band short-wavelength (blue) lights to more precisely understand… (More)
