Headache after running: what should you know?

Running increases breathing, heart rate, and muscle demand. Head pain may develop when effort is intense, the weather is hot, fluids are limited, or you have not eaten enough. Tight neck and shoulder muscles can contribute as well. A headache that begins abruptly during exertion, is unlike previous headaches, or comes with neurological symptoms needs a clinician to exclude more serious causes.

Stop and move to a cool place. Rest, loosen tight clothing, and drink fluids gradually if you are awake and able to swallow. Eat a light snack if you missed a meal. Avoid returning to exercise while symptoms continue. For future runs, build intensity gradually, warm up, protect yourself from heat, and record distance, pace, weather, food, fluids, and headache timing.

Call emergency services for a thunderclap headache, collapse, confusion, fainting, seizure, weakness, numbness, trouble speaking, chest pain, breathing difficulty, repeated vomiting, or severe overheating. Seek medical review if exercise headaches recur, last longer than expected, or begin during rather than after activity.

Ask whether your symptoms fit an exertion headache, whether blood pressure or other checks are needed, and how to restart training safely. Mention your pace, temperature, hydration, food intake, medicines, and any family history of migraine or sudden neurological illness.
