Standard room lighting suppresses melatonin in 99 percent of people study finds

What was said

"What they found is that compared to dim light, exposure to just high room like brightness, like light brightness, it suppressed melatonin in 99% of individuals. What this essentially means, like when we look at all this data, is that your body's like internal night, so to speak, is being shortened by 90 minutes just from standard room lighting, more than your phone, more than all these other things."

Research published in the Journal of Clinical Endocrinology Metabolism reveals that ordinary room lighting below 200 lux suppresses melatonin production in 99% of people, effectively shortening the body's internal night by 90 minutes. This contradicts popular focus on phone screens as the primary sleep disruptor. The finding implicates ambient lighting as a more significant factor in cortisol dysregulation and sleep onset issues.
