Why Does My Head Hurt After Bicep Curls?

Published in Headaches 3 mins read

The most likely reason your head hurts after bicep curls is due to an exertion headache.

Exertion Headaches Explained

Exertion headaches, also known as exercise headaches, involve head pain that develops during or immediately following physical activity. These headaches tend to appear suddenly and can disappear within minutes or hours, though they might last up to a couple of days.

  • Primary Exertion Headaches: These are usually harmless and not related to any underlying medical condition. The exact cause isn't fully understood, but they are thought to be linked to increased blood flow to the head during exercise.
  • Secondary Exertion Headaches: These are less common but can be caused by underlying problems, such as:
    • Sinus infections: Pressure changes during exercise can exacerbate sinus pain.
    • Dehydration: Insufficient fluid intake can contribute to headaches.
    • Underlying vascular conditions: Rarely, exertion headaches can be a symptom of more serious conditions affecting blood vessels in the brain.

Possible Causes Specific to Bicep Curls

While exertion headaches are the most probable cause, here are a few other factors related to bicep curls specifically:

  • Improper Breathing: Holding your breath during exertion (like lifting weights) increases pressure in your chest and abdomen, which can travel up to your head and trigger a headache. This is known as the Valsalva maneuver.
  • Neck Tension: Bicep curls, especially with heavy weight, can cause you to tense your neck and shoulder muscles. This tension can radiate up into your head, leading to a tension headache.
  • Dehydration/Electrolyte Imbalance: As mentioned before, dehydration and electrolyte imbalances (like low sodium or potassium) can trigger headaches, especially during or after exercise. You lose fluids and electrolytes through sweat.

What Can You Do?

  • Stay Hydrated: Drink plenty of water before, during, and after your workout. Consider an electrolyte drink if you're sweating a lot.
  • Proper Breathing: Breathe consistently throughout your set. Exhale during the exertion phase (lifting the weight) and inhale during the relaxation phase (lowering the weight).
  • Warm-up Properly: A good warm-up prepares your muscles and cardiovascular system for exercise, reducing the risk of sudden increases in blood pressure. Include light cardio and dynamic stretching.
  • Maintain Good Posture: Keep your neck and shoulders relaxed during the exercise. Avoid shrugging or tensing up. Focus on controlled movements.
  • Lower the Weight: If the headaches are frequent, try reducing the weight you're lifting to see if it helps.
  • Consult a Doctor: If the headaches are severe, persistent, or accompanied by other symptoms (fever, stiff neck, vision changes, nausea), see a doctor to rule out any underlying medical conditions.

Summary

Headaches after bicep curls are most likely exertion headaches related to increased blood flow or tension. Simple lifestyle adjustments such as proper hydration, breathing techniques, and warm-ups can help prevent them. If they persist or worsen, seek medical advice to rule out any other causes.
