If you’re one of the 620 million people worldwide who regularly lace up their running shoes, you might be unknowingly increasing your injury risk by cutting corners on sleep. A new study reveals that sleep deprivation running injury is a real and significant threat — runners with poor sleep quality or short sleep duration face nearly double the injury risk compared to those who rest well. The research, conducted by Professor Jan de Jonge at Eindhoven University of Technology in the Netherlands, shows that sleep isn’t just about recovery; it’s a critical factor in preventing injuries before they happen.
Sleep Deprivation Running Injury: The Study of 425 Runners
Published in the journal Applied Sciences in 2025, the study surveyed 425 recreational runners about their sleep habits and injury history. The researchers didn’t just look at how many hours participants slept — they examined sleep quality, sleep disorders, and how rested runners felt upon waking. The results were striking: runners who reported poor sleep were 1.78 times more likely to have experienced an injury compared to those with consistent, high-quality sleep.
Even more concerning, the data showed that poor sleepers faced a 68% likelihood of sustaining at least one injury over a 12-month period. That’s not a small increase — it’s a dramatic jump that should make every runner take notice. “Our research shows that poor sleepers were 1.78 times more likely to report injuries than those with stable, good quality sleep,” Professor de Jonge explained. “That’s a strong reminder that how well you rest is just as important as how hard you train.”
Why Sleep Matters for Injury Prevention
Sleep is when your body does its most important repair work. During deep sleep stages, your body releases growth hormone, which is essential for tissue repair and muscle recovery. When you’re sleep-deprived, this recovery process is disrupted. Your muscles don’t repair as efficiently, your tendons and ligaments remain vulnerable, and your body’s ability to adapt to the physical stress of running is compromised.
But it’s not just physical. Sleep deprivation also affects your coordination, reaction time, and decision-making. When you’re tired, you’re more likely to misstep on uneven terrain, lose focus on your form, or push through pain signals that would normally tell you to slow down. All of these factors combine to create a perfect storm for injury.
The Gulf Context: Why This Matters for Saudi Runners
For runners in Saudi Arabia and the Gulf region, sleep challenges are often amplified by the climate and lifestyle. The extreme heat means many runners train early in the morning or late at night, which can disrupt natural sleep patterns. Air conditioning, while necessary, can create dry environments that affect sleep quality. Additionally, the cultural tendency toward late-night socializing and early work start times can lead to chronic sleep debt.
Research specific to athletes in hot climates shows that heat acclimation itself can disrupt sleep, creating a double challenge. Runners training for events like the Riyadh Marathon or participating in community running groups in Jeddah need to be especially mindful of their sleep hygiene. The Asir Mountains, with their cooler temperatures and misty green peaks, offer an ideal training environment, but even there, proper rest remains essential.
Beyond Duration: Sleep Quality Counts Too
The study made an important distinction: it’s not just about how many hours you spend in bed. Runners who struggled with falling asleep, woke up frequently during the night, or rarely felt rested were the most prone to injury. This means that even if you’re getting seven or eight hours of sleep, if that sleep is fragmented or poor quality, you may still be at elevated risk.
Consistency also matters. Runners who maintained regular sleep schedules — going to bed and waking up at roughly the same times each day — reported significantly fewer injuries. This aligns with broader research on circadian rhythms and athletic performance. Your body thrives on regularity, and erratic sleep patterns can throw off hormonal balance, recovery processes, and even your motivation to train safely.
Practical Steps to Protect Yourself
The good news is that sleep is something you can actively improve. Professor de Jonge and his team emphasize that runners should treat sleep as a performance priority, not an afterthought. Here are evidence-based strategies to reduce your injury risk through better sleep:
- Aim for 7-9 hours per night, and consider adding short naps if you’re training intensely
- Keep a consistent schedule — go to bed and wake up at the same time daily, even on weekends
- Create a sleep-friendly environment — cool, dark, and quiet; limit screen time at least 30 minutes before bed
- Watch your caffeine and alcohol intake, especially in the hours before sleep
- Listen to your body — if you’re consistently tired, adjust your training load rather than pushing through fatigue
- Track your sleep using a journal or wearable device to identify patterns and problem areas
A Shift in How We Think About Training
This research challenges a common assumption in running culture: that more training always equals better results. The reality is that without adequate sleep, your training may be doing more harm than good. “We often assume that more training equals better performance, but that’s not necessarily the case,” Professor de Jonge notes. “Runners, especially those balancing training with work, family, and social commitments, may actually need more sleep than average adults to recover properly.”
This is particularly relevant for recreational runners who aren’t professional athletes with dedicated recovery time. If you’re juggling a demanding job, family responsibilities, and a running routine, sleep becomes even more critical. It’s the foundation that allows everything else to work effectively.
Key Takeaways for Runners
- Poor sleep increases running injury risk by 78%, with a 68% chance of injury over 12 months for poor sleepers
- Sleep quality matters as much as sleep duration — fragmented or restless sleep still elevates risk
- Consistent sleep schedules are associated with significantly fewer injuries
- Runners in challenging climates, like the Gulf region, need to be especially vigilant about sleep hygiene
- Treat sleep as a training priority, not an optional extra — it’s when your body actually gets stronger
- Simple changes like limiting screens before bed and maintaining a regular schedule can make a major difference
