🧠💤⚡ Sleep loss damages the brain’s wiring insulation, called myelin, leading to conduction delays and disrupted interhemispheric synchronization. Cognitive and motor performance are affected, and the deficits persist beyond recovery sleep. Restoring cholesterol delivery to myelin prevents them.

Either a workout or nap can help your sleep-deprived brain: People who either completed 20 minutes of moderate-to-vigorous exercise or took a 90-minute nap performed about 22% better on memory tests after 30 hours without sleep than those who did neither.…
💪 A 20-minute workout or a 90-minute nap can significantly improve memory after 30 hours without sleep, with participants performing about 22% better on memory tests.
🧠 While both exercise and napping boosted memory, they worked differently: naps helped the brain recharge, while exercise made it use its resources more efficiently.
💡 These findings offer practical ways to maintain cognitive function, especially in demanding jobs where sleep loss is common, suggesting exercise as an accessible alternative when naps aren't feasible.
