Introduction

Concussions are a type of traumatic brain injury (TBI) that can have serious short-term and long-term effects if not managed properly. The value of rest is often understated in the recovery process of concussions. This article aims to emphasise the importance of both physical and cognitive rest and provides practical tips to help promote a successful recovery from a concussion.

Understanding concussions

A concussion is a type of brain injury caused by a blow to the head or a sudden jolt that causes the brain to move rapidly back and forth. This movement can lead to chemical changes in the brain and sometimes damage brain cells. Symptoms of a concussion can vary widely and may include headaches, dizziness, confusion, memory problems, nausea, and even emotional disturbances such as irritability or depression.

Concussions can result from various incidents, including sports injuries, car accidents, falls, and other physical impacts. The effects of concussions can be immediate or may develop over hours or days. It is important to not ignore your symptoms and seek medical help. If not properly treated, a concussion can lead to prolonged symptoms and further complications, including the risk of recurrent concussions and more severe brain injuries.¹

The role of rest in concussion recovery

Rest is key for concussion recovery as it allows the brain the time it needs to heal and regain its normal functioning. Both physical and cognitive rest are essential immediately after the injury and throughout the recovery period.

Physical rest

Physical rest involves avoiding activities that can exacerbate symptoms or increase the risk of another head injury. This means refraining from sports, exercise, and other strenuous activities. During the initial days following a concussion, it is crucial to get plenty of sleep and rest during the day as well as engaging in light activity at least 2 days after concussion.^2,3

Activities to avoid

• Sports
• Physical exertion, like lifting heavy objects
• Driving or operating heavy machinery

Recommended practices

• Ensuring good quality sleep each night
• Taking naps
• Engaging in light activity, including aerobic exercise

The duration of physical rest varies depending on the severity of the concussion and individual response to the injury. Although strict rest is not necessary, only light activities are recommended, followed by a progressive reintroduction of physical activities.

Cognitive rest

Cognitive rest is also extremely important for recovery. This type of rest involves limiting activities that demand significant mental effort and concentration, which can aggravate symptoms and delay recovery.⁴

Activities to avoid

• Screen time (computers, smartphones, TV)
• Reading or writing
• Playing video games
• Doing complex problem-solving or multitasking

Recommended practices

• Resting in an environment that is quite and where the light is not too bright
• Taking time to do relaxing activities, such as meditation and breathing exercises
• Listening to soft music in low volume or engaging in non-strenuous hobbies

Similarly to physical rest, the time it takes for cognitive rest depends on the individual and the severity of their symptoms. Usually, a few days to a week is recommended and you can gradually return to your usual activities as symptoms improve.

Balancing rest and gradual return to activity

While rest is crucial in the early stages of concussion recovery, it is also important to gradually reintroduce activities to avoid deconditioning and other complications.¹

Signs of readiness to resume activities

• Absence of concussion symptoms at rest
• Ability to perform light physical activities without symptom recurrence
• Clearance from a healthcare professional

Guidelines for gradual return to physical activities

• Start with light aerobic exercises, such as walking or light stretching exercises.
• Progressively increase the intensity and duration of activities.
• Introduce moderate sport activities without risk of head impact.
• Engage in non-contact sport activities.
• Participate in full-contact practice after medical clearance.
• Resume usual sport activities.

Guidelines for gradual return to cognitive activities

• Start with light cognitive activities, such as easy reading, coloring, or listening to music.
• Gradually increase the complexity of mental activities.
• Resume school or work only for half days and then progressively increase to full school or work days.

During this time, it is important to monitor your symptoms and reduce activities if symptoms recur.

Professional guidance and monitoring

Seeking professional medical advice is crucial for anyone who has sustained a concussion. Healthcare professionals, including doctors and concussion specialists, can provide personalised recovery plans and monitor progress to ensure safe and effective recovery.

Role of healthcare professionals

• Conducting thorough assessments and diagnosis
• Developing individualised rest and recovery plans
• Providing clearance for return to activities
• Monitoring for potential complications

Regular follow-ups and assessments are important to adjust recovery plans as needed and to address any persistent symptoms.

Potential risks of ignoring rest

Ignoring the need for rest after a concussion can cause serious consequences. Prolonged recovery time, increased risk of recurrent concussions, and the potential for chronic issues such as post-concussion syndrome are significant risks. Post-concussion syndrome involves persistent symptoms that may be present for weeks, months, or longer. This has a significant impact on an individual’s daily life.

Case studies and real-life examples

Real-life examples highlight the importance of proper rest in concussion recovery:

Athlete's Recovery

A high school athlete who sustained a concussion during a football game followed a strict rest regimen. He avoided physical and cognitive activities for a week, gradually returned to light activities, and fully recovered within three weeks, returning to play safely.

Neglected Rest

Another athlete ignored medical advice and returned to play too soon, subsequently experiencing worsening symptoms and prolonged recovery. Because of this he could not do sports for several months.

These examples demonstrate the stark contrast between proper and improper management of concussion recovery. Although it is normal to want to return to normal activities as soon as possible, it is important to give our bodies time to recover so that we are at our best.

Tips for supporting someone with a concussion

Supporting someone with a concussion involves creating an environment conducive to rest and recovery:

• Remind them of the importance of rest and adherence to the guidelines provided by health professionals
• Minimise distractions by creating a quiet house environment
• Assist with daily activities that require physical and cognitive strain

Monitor their symptoms and ensure that they are followed by a medical professional

Summary

Concussions are serious injuries that require proper management. Rest is a vital component of concussion recovery, providing the brain with the necessary time and conditions to heal. Both physical and cognitive rest play critical roles in this process, helping to reduce symptoms and prevent further injury. By prioritising rest and following a gradual return to activities, individuals can ensure a successful recovery from concussions. Promoting awareness and understanding of the importance of rest in concussion management is essential for preventing long-term complications and ensuring overall brain health.

By understanding the crucial role of rest in concussion recovery and following appropriate guidelines, individuals can recover more effectively and safely from concussions, ensuring long-term brain health and well-being.

Addressing common myths and misconceptions about concussions

Despite growing awareness, several myths and misconceptions about concussions persist which can hinder effective recovery. Addressing these myths is crucial to ensure proper understanding and management.

Myth 1: A concussion requires loss of consciousness

Reality: Many concussions occur without any loss of consciousness. Symptoms can range from mild to severe, and even a minor hit can cause significant injury.

Myth 2: You need to wake a concussed person every few hours

Reality: Although this was a common practice in the past, current guidelines suggest that allowing a person to sleep is beneficial for recovery. However, it is important to monitor them closely for any worsening symptoms.

Myth 3: You can always observe the effects of a concussion immediately

Reality: Concussion symptoms can appear immediately or develop over several hours or days. Therefore, it is important to watch for delayed symptoms such as headaches, confusion, or mood changes.

Myth 4: Children and teenagers recover from concussions faster than adults

Reality: In fact, children and teenagers may take longer to recover from concussions and are more susceptible to long-term effects. Their developing brains are more vulnerable, making proper rest and gradual return to activities even more critical.

Myth 5: Only athletes get concussions

Reality: While athletes are at higher risk because of the activities they perform, concussions can happen to anyone, including children, adults, and the elderly. For instance, falls, car accidents, and everyday accidents can all lead to concussions.
