When your circadian rhythm is chronically disrupted, your body builds up wear and tear over time

This is what we call allostatic load

The retina specifically plays a key role in setting your master and peripheral circadian clocks through light, so if it gets damaged through isolated blue light exposure (as in most people’s experience), it adds extra stress to the entire system

Ongoing circadian disruption slowly wears your body down, and retinal damage makes that stress worse because it disrupts how your brain senses and responds to light

Retinal damage does NOT stay local

It weakens your body’s ability to keep time, amplifying the overall physiological stress from circadian disruption
