Injuries And Sleep: My Unlikely Bedfellows

Sleep is meant to be a time for your body to rest and recover, but ironically, it can also be a time when you can get injured. From sleeping in the wrong position to underlying health conditions, there are various reasons why you might wake up with an injury. In this article, we will explore the different ways in which people can hurt themselves while sleeping and provide tips on how to prevent sleep-related injuries. Whether it's a sore neck, a twisted ankle, or something more serious, understanding the causes of sleep injuries can help you improve your sleep quality and wake up feeling refreshed and rejuvenated.

Traumatic brain injuries (TBIs) can cause sleep disturbances

Sleep disturbances are a common occurrence following a Traumatic Brain Injury (TBI), with studies showing that they affect 30-70% of individuals. Insomnia, fatigue and sleepiness are the most frequent post-TBI sleep complaints, with other common sleep disorders including narcolepsy, sleep apnea, periodic limb movement disorder, and parasomnias.

The brain controls sleep by putting the body to rest, so an injury to the brain can lead to changes in sleep. The internal clock in the brain controls when people sleep and wake every day, so if injured, the brain may not be able to tell the body to fall asleep or wake up. There are chemicals in our body that help us sleep, and an injury can change the way these chemicals affect the body. If the brain mechanisms for starting and stopping sleep are injured, a condition called post-traumatic hypersomnia may result, causing a person to sleep many hours more than normal.

There are two main types of TBI that negatively impact sleep: contact injuries, which cause focal brain damage, and acceleration or deceleration injuries, which cause more generalised brain damage. The type of sleep disturbance may also vary according to the number of TBIs sustained.

The location of the injury within sleep-regulating brain regions also determines the type of sleep disturbance resulting from a closed head injury. Post-traumatic hypersomnia is seen when areas involving the maintenance of wakefulness are damaged. These regions include the brainstem reticular formation, posterior hypothalamus, and the area surrounding the third ventricle.

In addition, depression, anxiety, and pain are common TBI comorbidities that substantially influence sleep quality.

Sleep is important for recovery and can speed up healing

The main role of sleep in your recovery is to ensure the growth of new, healthy tissues at the site of your injuries. When entering sleep, the brain signals the release of large amounts of growth hormones. Hormones such as Human Growth Hormone (HGH) and testosterone are responsible for building new proteins to replace damaged ones in muscle, tendon, ligament, and bones. Hormone levels are highest during sleep and, as a result, the majority of repair occurs at night. A single night of sleep deprivation can lower testosterone levels by 24% and slow the repair process down by 18%. This effect is likely amplified when you have repeated days with insufficient sleep. Consistent, plentiful sleep is necessary for your body to reach its potential for rapid healing.

Sleep can also lower stress levels. Dealing with an injury can be a stressful time in your life. When stressed, your body releases a hormone called cortisol, known as the “Stress hormone”. Cortisol is responsible for the breakdown of body tissues for energy, including proteins. Since this is the opposite of growth hormones, high levels of stress and cortisol are counter-productive to healing. This is where sleep can help. Sleep acts as a built-in stress reliever, lowering levels of cortisol in your bloodstream. Less cortisol leads to growth hormones becoming more efficient in rebuilding injured tissues. There’s also the added benefit of waking up with less stress and improved mood to face the challenges of your recovery.

In addition to the above, sleep can help prevent new or old injuries from returning by:

• Increasing alertness and reducing the chance for accidents or lapses in judgement
• Decreasing fatigue
• Increasing strength and muscle protein growth, lowering the risk for strain or tear
• Increasing learning of motor skills and improving movement efficiency and coordination when training these skills with rehabilitative exercises

Therefore, adopting healthier sleep habits can reduce your risk for developing a chronic injury and injury recurrence.

Sleep lowers stress levels and improves mood

Sleep is essential for our physical and mental health. It is the time when our bodies repair and rejuvenate, and our brains recharge. Getting a good night's sleep is particularly crucial when recovering from an injury.

Secondly, sleep improves our ability to process stress and react in an appropriate way. A good night's sleep can boost our mood, outlook, and temperament. Research has shown that most people would be happier, healthier, and safer if they slept an extra 60 to 90 minutes per night.

Additionally, sleep improves our overall mental well-being. It facilitates memory consolidation and enhances our concentration and judgment. On the other hand, sleep deprivation can negatively impact our mood, energy levels, and cognitive abilities. It can also increase the risk of developing chronic health conditions such as heart disease, stroke, and depression.

To improve sleep quality and duration, it is essential to practice good sleep hygiene. This includes establishing a regular bedtime and wake-up routine, limiting caffeine and alcohol intake, avoiding screens before bed, and creating a relaxing bedroom environment. Making these lifestyle changes can help reduce stress levels, improve sleep, and promote a faster recovery from injuries.

Lack of sleep can delay the healing process and lead to complications

Sleep is essential for our physical and mental health, and not getting enough of it can have serious consequences. When it comes to injury recovery, sleep is crucial. During sleep, the body releases growth hormones that aid in repairing and growing muscles and other tissues. If you don't get enough sleep, the secretion of these hormones decreases, hindering the healing process and potentially leading to complications.

The "deep sleep" phase of the sleep cycle, which recurs approximately every 90 minutes, is when the body releases the highest levels of growth hormones. These hormones, such as Human Growth Hormone (HGH) and testosterone, are responsible for building new proteins to replace damaged ones in muscles, tendons, ligaments, and bones. A single night of sleep deprivation can lower testosterone levels by 24% and slow the repair process by 18%.

In addition, sleep helps in injury recovery by reducing stress levels. When stressed, the body releases cortisol, known as the "stress hormone," which breaks down body tissues for energy. Sleep acts as a natural stress reliever, lowering cortisol levels and allowing growth hormones to more effectively rebuild injured tissues.

Not getting enough sleep can also increase your risk of developing various health conditions, including high blood pressure, heart disease, and type 2 diabetes. It can also weaken your immune system, making it harder for your body to fight off infections and prolonging the recovery process from illnesses.

Furthermore, sleep deprivation can affect your central nervous system, causing difficulties with concentration, learning, and coordination. It can also lead to mood swings, impaired decision-making, and even hallucinations.

To promote injury recovery and overall health, it is essential to prioritize sleep and maintain healthy sleep habits. This includes establishing a consistent sleep schedule, limiting caffeine and alcohol intake, avoiding screens before bed, and creating a relaxing bedtime routine.

Sleep positions and mattresses can affect recovery

Sleep is an essential tool for injury recovery. It helps lower stress levels and promotes the growth of new, healthy tissues at the site of injuries. The hormones released during sleep, such as Human Growth Hormone (HGH) and testosterone, are responsible for building new proteins to replace damaged ones in muscles, tendons, ligaments, and bones. Therefore, it is crucial to get sufficient, high-quality sleep to support the recovery process.

Sleep positions and mattresses play a crucial role in the quality of sleep and can significantly affect recovery. Sleeping on your side or back is generally considered better for recovery than sleeping on your stomach. Side sleeping promotes healthy spinal alignment and reduces the likelihood of back pain, especially when supported with pillows. It is also beneficial for individuals with acid reflux, back pain, or sleep apnea. Back sleeping keeps the spine aligned and evenly distributes body weight, preventing aches in the neck or back. This position is recommended for individuals with nasal congestion or neck pain.

The right mattress is essential for supporting healthy sleep positions and promoting recovery. A good mattress should provide proper spinal alignment, keeping the spine in a neutral position to reduce strain on muscles and joints. Memory foam mattresses are particularly beneficial for supporting the spine and reducing back pain. Additionally, a durable and responsive mattress ensures consistent support, which is crucial for individuals with higher muscle mass, such as athletes.

Temperature regulation is another important factor. Active individuals or those with higher metabolic rates may sleep hotter, and a cooling mattress can help prevent night sweats and interruptions to sleep. Some mattresses feature cooling technology, such as gel-infused memory foam or breathable covers, to maintain an ideal sleep temperature.

In addition to temperature regulation, pressure relief is vital for joint health. A quality mattress balances support and pressure relief, ensuring that tension doesn't build up in the hips, shoulders, or knees. Memory foam or hybrid mattresses with latex or memory foam can cradle pressure points, providing comfort and preventing aches and pains.

Overall, sleep positions and mattresses significantly impact recovery. Adopting healthy sleep positions and investing in a quality mattress that supports your unique needs can accelerate healing, enhance comfort, and improve sleep quality, all of which contribute to a successful recovery.
