E6 - How light influences human physiology - Show notes Main paper that I discuss: The influence of bright and dim light on substrate metabolism, energy expenditure and thermoregulation in insulin-resistant individuals depends on time of day https://doi.org/10.1007/s00125-021-05643-9 Other papers and resources that I refer to : The MyLux app for smartphones is to my surprise not available anymore when I checked the appstore, but my explanations on its use and limitations would apply to any other lux-measuring app as they all measure lux via the smartphone-integrated camera.
