Summary

Bright light therapy utilizes a high-intensity lamp (typically 10,000 lux) to mimic natural sunlight, which helps regulate the body's internal clock. Exposure, particularly in the morning, suppresses melatonin production and can increase serotonin, thereby entraining the circadian rhythm. For healthspan, this translates to improved sleep quality, mood stabilization, and enhanced daytime energy levels, which are foundational for metabolic health and cognitive function.

Purpose

Regulates circadian rhythm and mood via bright light exposure.
