Weather and migraines: Is there a neurological connection?

Weather changes are often cited as triggers for migraines, but is there a scientific basis for this association? Let’s explore the relationship between weather patterns and migraine attacks.

Understanding Migraines

Migraines are neurological disorders characterized by severe headaches, often accompanied by other symptoms such as nausea, sensitivity to light and sound, and visual disturbances. While the exact cause of migraines is not fully understood, they are believed to involve abnormal brain activity and changes in the levels of certain neurotransmitters.

Weather Triggers

Many migraine sufferers report that changes in weather conditions can trigger or exacerbate their symptoms. Common weather-related triggers include:

  • Barometric pressure changes: Rapid changes in barometric pressure, which often occur during storms or changes in altitude, are commonly cited as triggers for migraine attacks.
  • Temperature fluctuations: Extreme heat or cold can also trigger migraines in some individuals.
  • Humidity levels: High humidity levels may increase the risk of migraine attacks for some people.

Scientific Evidence

While anecdotal evidence suggests a link between weather changes and migraines, scientific studies on the topic have yielded mixed results. Some studies have found a correlation between specific weather patterns and migraine onset, while others have found no significant association.

One theory is that changes in barometric pressure may affect the pressure inside the skull, leading to changes in blood flow to the brain and triggering migraine attacks in susceptible individuals. Additionally, changes in temperature and humidity may influence the release of certain neurotransmitters or trigger inflammatory responses in the brain, contributing to migraine symptoms.

Managing Weather-Related Migraines

For migraine sufferers who experience weather-related triggers, managing these triggers may help reduce the frequency and severity of migraine attacks. Some strategies for managing weather-related migraines include:

  • Tracking weather patterns: Keeping a migraine diary to track weather patterns and migraine symptoms can help identify potential triggers and patterns.
  • Avoiding triggers: Minimizing exposure to known weather triggers, such as extreme temperatures or high humidity levels, may help prevent migraine attacks.
  • Managing stress: Stress is a common trigger for migraines, so practising relaxation techniques such as deep breathing, meditation, or yoga may help reduce the risk of migraine attacks during periods of weather-related stress.
  • Seeking medical treatment: In some cases, medication or preventive treatments prescribed by a healthcare professional may be necessary to manage severe or frequent migraines triggered by weather changes.


While the relationship between weather and migraines remains complex and not fully understood, many migraine sufferers report anecdotally that changes in weather conditions can trigger or worsen their symptoms. Further research is needed to better understand the underlying mechanisms linking weather patterns and migraine attacks and to develop more effective strategies for managing weather-related migraines.
