Here’s What It Means If You Get A Headache After Working Out

We’ve written before at HuffPost UK about what it means if your face goes bright red after exercise (luckily, it’s usually nothing to worry about).

Sometimes, though, getting out of breath after climbing the stairs really is worth chatting to your GP about.

So, what does it mean if you get a headache after being active?

Speaking to HuffPost UK, Dr Giuseppe Aragona, GP and medical adviser for Prescription Doctor, shared his thoughts on when to worry – and what is completely normal.

Dr Aragona said post-exercise headaches “are often linked to normal physiological responses to exertion”.

They can sometimes happen thanks to water loss, hot or humid conditions, inadequate ventilation, or failing to warm up properly.

“Sudden increases in blood pressure during strenuous activity can dilate blood vessels in the brain, contributing to headache,” the GP said.

“Low blood sugar from exercising without eating, poor posture, and neck muscle tension may also play a role. Cold weather can similarly trigger headaches, particularly when running outdoors in freezing conditions.”

Chilly climes can contribute to post-workout headaches because of the sudden temperature shift, inhaling cold air, and tensed neck muscles from shivering, he continued.

Sometimes, however, it’s worth speaking to an expert about post-exercise headaches.

“Medical assessment is warranted if headaches are sudden and severe, progressively worsening, or accompanied by neurological symptoms such as weakness, visual disturbances, confusion, collapse, or fever,” advised Dr Aragona.

“Headaches that occur with coughing, straining, sexual activity, or that begin after age 40 should also be evaluated to rule out secondary causes.”

Additionally, some people get post-exercise migraines, which are more intense than headaches.

They typically appear as “one-sided, pulsating headaches” and may be accompanied by “nausea, vomiting, sensitivity to light or sound, or visual disturbances like flashing lights or zig-zag patterns,” the GP said.

“Recurrent or disabling headaches, or those showing migraine features, should prompt discussion with a GP. Keeping a headache diary can help identify patterns and triggers, allowing for appropriate diagnosis and management.”

If you’re pretty sure your post-exercise headaches are “normal”, there are steps you can take to reduce their symptoms.

“Most post-exercise headaches can be managed by staying well hydrated, eating balanced meals, warming up properly, avoiding sudden intense activity, gradually increasing exercise intensity, and focusing on breathing,” the doctor ended.

“Over-the-counter pain relief like paracetamol or ibuprofen may help if there are no contraindications.”
