Cortisol test explores blue light glasses effectiveness
ZDNet·
An individual conducted a personal experiment tracking cortisol levels at home to assess the efficacy of blue light glasses. The study aimed to determine if reducing exposure to blue light from evening screen time could positively impact stress hormone levels and sleep quality. By monitoring cortisol, a key indicator of stress, the experiment sought to provide empirical evidence for the benefits often claimed by proponents of blue light blocking technology. The results of this self-conducted test offer insights into the potential impact of screen time on physiological stress markers.
