First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether exposure to special light lamps at 5am could help people stay alert and think clearly after a full night without sleep. Researchers compared two different light devices to no light at all in 18 healthy adults. The goal was to see if light could reduce fatigue and improve cognitive performance, which might eventually help people with sleep disorders.
