Why Is Migraine Triggered By Weather Change?

Migraine is a neurological condition that causes a sudden throbbing headache. Though migraine attacks can occur at any time, there are certain triggers that can intensify pain and make it unbearable. It is observed that migraines get triggered by weather changes in some people. Onlymyhealth spoke to Dr. Aparna Gupta, Senior Consultant - Neurology, Indian Spinal Injuries Centre(ISIC) to understand how migraine is affected by weather change. 

Why is Migraine Triggered By Weather Change?

These are the four causes of migraine when weather conditions change, according to  Dr. Gupta

Barometric Migraine

Migraine sufferers appear to be particularly sensitive to variations in weather. Bright sunshine, intense heat or cold, excessive humidity, dry air, windy or stormy weather, and barometric pressure shifts are all weather-related triggers. Environmental changes can provoke migraine. One must analyze the patterns and triggers. Such as some people may get migraine only in hot and humid weather whereas some may get migraine during the rainy season.

NOTE: This depends on an individual. Not every sufferer can get biometric migraine during a specific season.

Increased humidity

Migraine attacks appear to be triggered by increased humidity and temperatures. Sudden variations in humidity or temperature could also play a prominent role in triggering migraines. This can be prevented by not going out in extreme hot and humid weather.

Dehydration could be one reason for an increase in migraine attacks in hot or dry conditions. As per a research published in NIH, dehydration can cause headache and it may also exacerbate an underlying condition like migraine or headache disorders. This is because of fluid imbalance in the body. Human body needs fluids and electrolytes for healthy functioning. When you urinate, fluids and minerals like sodium and potassium are eliminated from the body. Drinking water helps in restoring them which prevents health issues including migraine. So, when you fail to replenish water loss, it can trigger dehydration migraine.


Even allergies can lead to migraine. Sometimes dust is one of the prominent triggers. People who tested positive for particular allergies, such as dust allergies, had more frequent migraine symptoms, according to the source.
