Sleep disturbances after a concussion are far more common than most people realize, affecting nearly two-thirds of patients and significantly delaying recovery. Researchers from Children's Hospital of Philadelphia studied 4,469 concussion patients aged 5 to 18 and found that 64% reported changes in sleep after their injury. This was higher than the 51% reported in earlier research. Even more concerning, sleep problems became the second strongest predictor of whether someone would take longer than 28 days to recover from their concussion. How Does a Concussion Disrupt Your Sleep? When you suffer a concussionâa functional brain injury caused by a blow or jolt to the headâthe damage can affect multiple regions of your brain that control sleep. "Damage to various regions of the brain after a traumatic brain injury, such as a concussion, can disrupt the sleep process," explains Dr. Vincent Schaller, medical director of Mid-Atlantic Concussion Alliance. "Sleep is a complex operation that requires the brain to basically orchestrate, and if you have a concussion this function can be affected." Beyond the direct damage, concussions can interfere with your brain's production of critical neurotransmitters. Neuro-trauma disrupts the production of melatonin and serotoninâthe chemicals your brain uses to regulate sleep and mood. This disruption can lead to depression and anxiety, which further compromise your ability to concentrate and remember things. What Types of Sleep Problems Follow a Concussion? The sleep disturbances that follow a concussion vary widely from person to person. Some people feel excessively sleepy in the first week after injury, while others struggle with insomnia for months. Here are the most common sleep disorders that develop after concussion: - Insomnia: Difficulty falling or staying asleep, one of the most frequently reported post-concussion sleep problems. - Hypersomnia: Excessive daytime sleepiness even after long stretches of sleep, also called excessive daytime sleepiness (EDS). - Delayed Sleep Phase Syndrome (DSPD): A disruption in your normal sleep-wake cycles that leads to excessive daytime sleepiness and difficulty maintaining a regular schedule. - Sleep Apnea: A condition where breathing stops and starts repeatedly during sleep, often characterized by loud snoring and feeling tired even after a full night's rest. - Restless Leg Syndrome (RLS): An urge to move your legs because they feel uncomfortable, especially at night or when lying down. - Narcolepsy: Overwhelming daytime sleepiness with sudden, uncontrollable sleep episodes that make it difficult to stay awake. The Model Systems Knowledge Translation Center reports that sleep disorders are three times more common in traumatic brain injury patients than in the general population. This means if you've suffered a concussion, you're significantly more likely to experience sleep problems than someone without a brain injury. Why Sleep Matters for Brain Recovery Sleep isn't just about feeling restedâit's when your brain does critical maintenance work. Recent research from Boston University reveals something remarkable: during both REM (rapid eye movement) and non-REM sleep, your brain waves trigger a cleansing function that flushes out neurotoxins associated with disease. This "brain cleaning" process is essential for maintaining cognitive function and preventing long-term damage. For someone recovering from a concussion, this cleansing process becomes even more important. Sleep is actually a primary treatment for concussion recovery because it gives your brain the time and resources it needs to repair itself. The better you sleep, the faster your brain can heal. Steps to Improve Sleep After a Concussion - Establish Consistent Sleep Schedules: Go to bed and wake up at the same time every day to help regulate your circadian rhythm and support your body's natural sleep-wake cycle. - Create a Calming Bedtime Routine: Engage in relaxing activities like listening to music, stretching, or meditating at least one hour before bed to signal your body it's time to wind down. - Optimize Your Sleep Environment: Keep your bedroom dark, cool, and free from electronic devices including cell phones, which emit blue light that can interfere with melatonin production. - Limit Caffeine and Heavy Meals: Avoid caffeinated beverages or large meals within 4 to 6 hours before bedtime, as these can keep your nervous system activated. - Get Morning Sunlight Exposure: Spend time in natural daylight, especially in the morning, to improve your circadian rhythm and boost natural melatonin production. - Use White Noise or Nature Sounds: Playing white noise, wave machines, or rain sounds can mask disruptive environmental noise and improve sleep quality. - Manage Napping Carefully: If you nap, limit it to once per day, keep it before 3 p.m., and don't nap longer than 30 minutes. - Exercise During the Day: Aim for 30 to 60 minutes of aerobic exercise daily to improve energy regulation, but stop exercising at least 3 to 4 hours before bed. - Eat Sleep-Supporting Foods: Include foods rich in tryptophan like turkey, complex carbohydrates like whole grains, and vitamin B6 sources like milk, cheese, and leafy greens. - Try Breathing Exercises: Use breathing exercises or visualization techniques like counting sheep before sleep to calm your central nervous system. When Should You Consider Sleep Medication? Sometimes behavioral changes alone aren't enough. "Sometimes, post-concussion patients are prescribed medications to help them get the sleep they need in order for the brain to repair itself," says Dr. Schaller. However, any medication needs to be carefully selected based on individual factors including the type and severity of your brain injury, your medical history, other medications you're taking, and any supplements like melatonin or omega-3s you're using. The key is working with your concussion specialist or neurologist to find the right approach. "We want to help improve sleep, not work against it," Dr. Schaller emphasizes. Should You Sleep Immediately After a Concussion? There's an old myth that you should stay awake after a head injury to prevent complications. That's no longer considered best practice. Modern concussion treatment recognizes that sleep is actually beneficial for recovery. As long as you're communicating normally, don't have dilated pupils, and can walk without problems, sleep is generally considered one of the best things you can do for your injured brain. If you've experienced a concussion and notice changes in your sleepâwhether you're sleeping too much, too little, or struggling with insomniaâdiscuss it with your concussion specialist, neurologist, or medical provider. Sleep disturbances are a common part of recovery, but they're also treatable. By addressing sleep problems early, you can significantly improve your chances of a faster, more complete recovery.
