Testing calorie restriction and light glasses to reduce pilot fatigue

This study is testing whether two simple strategies—limiting food intake during overnight flying hours and wearing blue-enriched light-emitting glasses after rest breaks—can help commercial airline pilots stay more alert and perform better on long overnight flights. Researchers want to see if these approaches reduce fatigue and sleepiness compared to standard fatigue management advice.

Pilots flying long overnight routes often struggle with fatigue and reduced alertness, which can affect safety and performance. This trial is exploring whether these low-cost, practical interventions could be a better way to help pilots stay awake and alert during critical flight operations.
