Chronic Noise Exposure and Autonomic Strain

Persistent environmental noise can elevate autonomic activation and sleep fragmentation burden.

Structured Summary

Chronic environmental noise can act as a persistent low-grade stressor. Research links sustained exposure to autonomic activation patterns and sleep disruption.

Noise burden is structural: people may not fully control it day to day, but mitigation changes can reduce load.

Mechanism Pathway

Chronic noise exposure

Sympathetic activation and sleep fragmentation

Reduced recovery depth

Higher autonomic burden baseline
