Sudden fatigue after a concussion is a common symptom that can feel overwhelming and confusing. It happens because the brain has been injured and needs extra energy to heal. When you experience this kind of fatigue, it is important to manage it carefully to support recovery and avoid making symptoms worse.
First, recognize that fatigue after a concussion is normal and part of the brain’s healing process. Your body and brain are working harder than usual, even if you don’t feel physically tired. This mental and physical exhaustion can come on suddenly and may be accompanied by other symptoms like headache, dizziness, or difficulty concentrating[1][2].
To handle sudden fatigue, start by **resting smart**. This means taking breaks when you feel tired but avoiding complete inactivity. Light activity, such as gentle walking or simple household tasks, can help maintain circulation and prevent stiffness without overloading your brain[1][2]. Avoid strenuous exercise or heavy mental work until your symptoms improve.
**Prioritize sleep** because good quality sleep is essential for brain repair. Try to keep a regular sleep schedule, avoid screens before bedtime, and create a calm, dark environment for sleeping. If you find yourself sleeping much more or less than usual, or if your sleep feels unrefreshing, talk to a healthcare provider as this can affect your recovery[1][3][8].
It is also helpful to **pace your activities**. Alternate periods of activity with rest to prevent fatigue from worsening. For example, if you are reading or working on a computer, take short breaks every 20 to 30 minutes. Listen to your body and stop any activity that makes your symptoms worse[1][2].
Stay **hydrated and eat nutritious foods** to support your body’s healing. Avoid alcohol and caffeine as they can interfere with sleep and increase fatigue[2].
If your fatigue is severe, sudden, or accompanied by worsening symptoms such as confusion, repeated vomiting, or difficulty waking up, seek medical attention immediately. These could be signs of a more serious brain injury[4][6].
For some people, fatigue and other symptoms can last weeks or months, a condition known as post-concussion syndrome. If your fatigue persists beyond a few weeks or significantly impacts your daily life, consult a healthcare professional who may recommend therapies such as cognitive behavioral therapy or specialized rehabilitation[3][5].
Handling sudden fatigue after a concussion involves balancing rest with gentle activity, prioritizing sleep, pacing yourself, and seeking medical advice when needed. This approach helps your brain heal while minimizing the risk of prolonged symptoms.
