Summary

This study looked at whether a 30-minute daytime nap can help mentally tired endurance athletes feel better and think more clearly. Eleven male amateur athletes completed two sessions: one where they did mentally tiring tasks before napping, and another where they just napped. Researchers measured sleepiness, mental fatigue, and thinking speed after the nap to see if it helped recovery.
