Weather and Headaches — Is There a Connection?

The Short Answer

Yes, there is a real connection. Multiple studies have found that changes in barometric pressure, temperature, and humidity can trigger headaches and migraines in susceptible people.

Which Weather Changes Trigger Headaches?

What the Research Shows

A study published in the journal Neurology found that a 5 hPa drop in barometric pressure within 24 hours increased migraine risk by about 6%. Another study in Internal Medicine linked temperature drops of 5°C or more to increased emergency room visits for headaches.

Who Is Most Affected?

• People with a history of migraines
• Those with sinus conditions
• People with joint conditions (similar pressure sensitivity)
• About 50-60% of migraine sufferers report weather as a trigger

What You Can Do

• Track your headaches alongside weather data to identify your personal triggers
• Stay hydrated — dehydration amplifies weather-related headaches
• Wear sunglasses on bright days
• Consider taking preventive medication before known trigger days
• Maintain a consistent sleep schedule regardless of weather

The Nuance

Weather is rarely the sole cause. It is more often a contributing factor that, combined with stress, poor sleep, or dehydration, tips the balance.
