Concussions: Risks of Exercise After Head Injury

Trauma

After sustaining a head injury, I experienced headaches and fatigue.
The doctor diagnosed me with a mild concussion and advised bed rest.
However, due to a physical education test requirement, I performed over 50 push-ups.
I'm concerned whether this could cause further injury and what effects it might have.

In general, there should be no impact! It is recommended to continue with your usual routine and activities to facilitate a quicker return to normalcy.
However, if you still feel unwell, you may visit your physician again for further evaluation and treatment.

After sustaining a head injury and being diagnosed with a mild concussion, it's crucial to understand the implications of engaging in physical activity, especially rigorous exercises like push-ups. A concussion is a type of traumatic brain injury (TBI) that occurs when the brain is jolted or shaken inside the skull, often due to a blow to the head. Symptoms can include headaches, fatigue, dizziness, and cognitive disturbances, which can persist for days or even weeks.

Engaging in strenuous physical activity shortly after a concussion can exacerbate symptoms and potentially lead to more severe complications. The brain is in a vulnerable state following a concussion, and activities that increase heart rate or blood pressure can intensify symptoms like headaches and fatigue. This is particularly concerning because the brain requires rest to heal properly.
When you perform exercises like push-ups, your body undergoes physical stress, which can lead to increased intracranial pressure and may worsen your symptoms. The risk of further injury is also a concern; if you were to sustain another impact while your brain is still healing, it could lead to more significant damage, including prolonged recovery times or even more severe brain injuries.

The general recommendation after a concussion is to follow a gradual return-to-play protocol. This typically involves a period of physical and cognitive rest, followed by a stepwise increase in activity levels, monitored closely for any recurrence of symptoms. The initial rest period usually lasts at least 24 to 48 hours, but many healthcare providers recommend a longer period of rest, especially if symptoms persist.
If you experience symptoms such as increased headache, dizziness, nausea, or any new symptoms after exercising, it's essential to stop the activity immediately and consult with a healthcare professional. They may recommend further evaluation and a tailored recovery plan that considers your specific symptoms and needs.

In summary, while it may be tempting to push through physical activity for sports or fitness requirements, it is vital to prioritize your brain health. Engaging in strenuous exercise shortly after a concussion can lead to a longer recovery and increased risk of complications. Always consult with a healthcare provider before resuming any physical activity after a head injury, and adhere to their recommendations for a safe return to exercise.
