Résumé
Part of a series aimed at gathering all studies assessing the effects of polychromatic light on mood, physiology and cognition, this systematic review investigated the effects of polychromatic (white) light exposure on heart rate. High melanopic equivalent daylight illuminance (EDI) was hypothesized to be more strongly associated with fast heart rate than other α-opic EDIs. This effect was predicted to be more evident during the morning. The larger literature search identified 3,548 articles, of which 10 reported heart rate and were included in the current report. The spectral power distribution, illuminance, heart rate means and core methods for each article were documented. Using the luox app, α-opic EDIs were calculated for each of the five photoreceptors to characterize the light exposures in each study. Regression models were applied to determine how α-opic EDI, duration, and timing related to heart rate. Results showed that none of the five α-opic EDIs were significantly associated with heart rate (all estimates <4.21e⁻³, p >0.119). Light exposure in the morning (all estimates > |-6.40e⁻²|, p < 0.001) and longer light exposure duration (all estimates > |-7.94e⁻⁴|, p < 0.001) were found to be associated with slower heart rate. None of the light conditions available for the current review had an α-opic profile in which melanopic EDI exceeded the other α-opic EDIs, so the proposed relationship between high relative melanopic EDI and heart rate could not be tested.
