Summary
A new study of 425 recreational runners found that those who slept poorly—short durations, low quality, or frequent sleep problems—were 1.78 times more likely to report injuries, with a 68% chance of injury over 12 months. Researchers say sleep should be viewed as a performance priority, not an afterthought. Poor sleep undermines recovery: it reduces growth-hormone release, lowers blood flow, and breeds fatigue—making runners more prone to mistakes and injury.
