Recreational running is one of the most popular sports in the world, with over 620 million people running frequently for fun globally. Despite its many health benefits — including physical fitness, stress reduction, and increased life expectancy — running also carries a notably high injury burden, with more than five injuries occurring per 1,000 hours of running. [ABC News](https://abcnews.go.com/Health) It was against this backdrop that researchers set out to explore a factor that had been largely overlooked in injury prevention research: sleep.
The study was led by Jan de Jonge, a work and sports psychologist at Eindhoven University of Technology in the Netherlands and adjunct professor at the University of South Australia. Published in the journal *Applied Sciences*, it surveyed 425 recreational runners and tracked their sleep habits and injuries over the course of a year.

Instead of focusing only on how long people slept, the researchers also examined sleep quality and the presence of sleep disorders to better understand their combined effect on injury risk.

The results were striking. Runners who struggled with falling asleep, woke up frequently during the night, or rarely felt rested were the most prone to injury. In contrast, those who maintained consistent sleep schedules and felt well-rested reported significantly fewer injuries.

Participants who reported shorter sleep duration, poorer sleep quality, or frequent sleep problems were 1.78 times more likely to be injured, with a 68% chance of suffering from an injury within 12 months. [U.S. News & World Report](https://health.usnews.com/wellness) The researchers described this as compelling evidence that sleep is a critical — yet routinely underestimated — component of injury prevention for runners.
The biological reasoning behind these findings is well-supported. Sleep is a vital process that allows the body and mind to recover from physical and mental training demands. When sleep is disrupted or insufficient, the body’s ability to repair tissues, regulate hormones, and maintain focus all diminish — each of which can contribute to a higher injury risk. [CBS2 Iowa](https://cbs2iowa.com/news/nation-world/trying-to-improve-your-health-and-wellness-in-2026-keep-it-simple) Sleep deprivation also slows reaction times, reduces coordination, and degrades decision-making, meaning a sleep-deprived runner is more likely to misjudge a movement or lose balance in ways that lead directly to injury.

The study’s authors argue the findings carry important implications for recreational and competitive runners alike, as well as for coaches and health professionals. Runners — especially those balancing training with work, family, and social commitments — may actually need more sleep than the average adult to recover properly. Practical steps such as maintaining a regular bedtime, limiting screen exposure before sleep, reducing caffeine and alcohol intake, and keeping the bedroom quiet and cool can all help improve sleep quality and, by extension, reduce injury risk. [CBS2 Iowa](https://cbs2iowa.com/news/nation-world/trying-to-improve-your-health-and-wellness-in-2026-keep-it-simple) The core message is simple but powerful: how well you rest matters just as much as how hard you train.
