Can thunderstorms give you a headache?

Can thunderstorms really trigger headaches or migraine attacks?

Thunderstorms. They're pretty cool, right? Whether you love them, dread them, or simply take them in your stride, it's hard not to feel something when you hear the distant rumble of thunder followed by a jagged flash of lightning streaking across the sky.

Watching a thunderstorm unfold can make an ordinary day feel like a scene from a fantasy film. For some people, though, the experience is far less enjoyable. Instead of being something to marvel at, thunderstorms can trigger headaches and, in some cases, even migraine attacks.

Dr Nada Hindiyeh is a board-certified neurologist, a UCNS-certified headache specialist, and Director of Headache Medicine at the Metrodora Institute. She is also Chief Medical Officer at Haven Headache and Migraine Center in California.

Hindiyeh says she often sees an increase in patients having headaches or migraine attacks when stormy weather is on the way.

"Many people tell me that their migraine attacks become more frequent when there is a significant change in weather patterns," she says. "This includes changes in barometric pressure, humidity, temperature, seasonal transitions, and when a storm suddenly rolls in.

“Some people really are sensitive to weather changes. So when someone says they can ‘feel a storm coming’, I don’t dismiss it.”

Hindiyeh adds that the effects of thunderstorms on the human body aren't fully understood, and not everyone is affected. However, some people's nervous systems do appear to respond to subtle atmospheric changes before the weather visibly shifts.

Why people with migraine may be more sensitive to storms

If you live with chronic migraine, you may be more sensitive to changes in the weather than someone who only experiences the occasional tension headache.

That's because your nervous system is more responsive to environmental changes. As Hindiyeh explains, a drop in barometric pressure that most people wouldn't even notice may be enough to trigger a migraine attack.

“One study found that migraine attacks were more common on days with nearby lightning - even after accounting for changes in barometric pressure, temperature, humidity, and other weather conditions,” she says. “This suggests there may be something unique about thunderstorms themselves.”

Hindiyeh notes that researchers have proposed several possibilities - including electromagnetic changes from lightning, changes in air ions, and other atmospheric shifts. However, none have yet been proven.

“For now, the evidence tells us the association is real for some people,” she adds. “But the exact reason is still an active area of research.”

How to reduce your risk of storm-related headaches

If you find that you’re sensitive to weather changes, there are steps you can take before a storm arrives that may help reduce your chance of a headache or migraine attack.

Hindiyeh advises that one of the most important strategies is to understand your triggers and have a plan in place.

“If you know storms are a trigger, prioritise good sleep, stay well hydrated, don’t skip meals, and try to minimise other triggers around that time,” she suggests. “If you’ve been prescribed acute medication, taking it early - at the first sign of a migraine attack - often works much better than waiting until the attack becomes severe.”

She emphasises that one of the biggest mistakes you can make is waiting too long to treat the migraine attack. If weather is a consistent trigger for you, taking your prescribed medicine early is usually much more effective than waiting until the pain becomes severe.

“Another common mistake is relying on over-the-counter pain medications too often,” she adds. “This can lead to medication overuse headache and actually make headaches more frequent over time."
