Concussion Recovery: You Don’t Have to Just “Wait It Out”

Written By J.D. Whittemore

For years, the standard advice after a concussion was simple: rest in a dark room and wait for symptoms to resolve.

While early rest (24–48 hours) is important, research over the past decade has changed how we understand concussion recovery. Prolonged inactivity and complete shutdown — often referred to as “absolute rest” — may actually delay recovery in some individuals.

Today, we know recovery is more nuanced and more active.

What Is a Concussion?

A concussion is a mild traumatic brain injury that affects how the brain functions. It can occur after a direct blow to the head or a forceful impact to the body that transmits force to the brain.

Common symptoms include:

  • Headache

  • Dizziness

  • Sensitivity to light or noise

  • Brain fog

  • Balance problems

  • Neck pain

  • Fatigue

Not all concussions look the same — and not all symptoms come from the same system.

Relative Rest vs. Absolute Rest

After the initial 24–48 hours, current evidence supports a model of relative rest.

Relative rest means gradually reintroducing light physical and cognitive activity that stays below your symptom threshold. Instead of avoiding all stimulation, the goal is controlled exposure.

This may include:

  • Light walking or stationary cycling

  • Structured return-to-learn or return-to-work plans

  • Gradual increase in daily activities

  • Targeted therapeutic exercises

Recovery is not passive. It’s progressive.

How Physical Therapy Can Help

Many concussion symptoms involve systems that physical therapists are trained to evaluate and treat.

Depending on presentation, physical therapy may address:

Vestibular Dysfunction

If dizziness or motion sensitivity is present, vestibular rehabilitation exercises can help retrain balance and visual stability systems.

Oculomotor Impairments

Difficulty with eye tracking or convergence can contribute to headaches and fatigue. Targeted exercises may improve visual coordination.

Cervical Spine Involvement

Neck dysfunction often contributes to headache and dizziness after concussion. Addressing cervical mobility and strength can significantly reduce symptoms.

Exertion Intolerance

Some individuals experience symptom increases with elevated heart rate. Graded aerobic exercise — guided by symptom response — can help restore tolerance safely.

Return-to-Sport or Activity Planning

Recovery should match the demands of work, school, and athletics. A structured progression reduces risk of prolonged symptoms.

When Should You Seek Help?

If you’ve recently sustained a concussion and want guidance immediately following the injury, early evaluation can be helpful.

The first 24–48 hours are important for rest and monitoring, but after that, structured guidance can make a significant difference. Understanding how to safely reintroduce physical activity, cognitive tasks, and daily routines can help prevent unnecessary setbacks.

If symptoms:

  • Persist beyond a couple of weeks

  • Worsen with light activity

  • Interfere with work, school, or sport

  • Include ongoing dizziness or balance issues

It may be time for a more structured evaluation.

You don’t have to just wait it out.

Concussion management has evolved. An individualized, system-specific approach can help guide recovery more effectively.
