Dehydration:
High temperatures increase sweat loss, leading to dehydration, which is a major headache trigger. Dehydration reduces blood volume, potentially lowering blood flow and oxygen to the brain.
Heat-induced vasodilation:
Heat causes blood vessels to expand (vasodilation), which can increase pressure in the head and contribute to headache pain, especially in migraine-prone individuals.
Sun exposure:
Prolonged exposure to bright sunlight and glare can strain the eyes and brain, potentially triggering migraines or tension headaches.
Barometric pressure changes:
Often associated with hot weather fronts, changes in atmospheric pressure can affect people sensitive to these shifts, like migraine sufferers.
Sleep disruption:
Heat can interfere with sleep quality, and poor sleep is a well-known headache trigger.
Triggers for migraines:
For people with migraines, heat is a common environmental trigger, often combining with other factors like light, dehydration, or stress.
Heat exhaustion and heat stroke:
Prolonged exposure to high temperatures can lead to heat-related illnesses, with headaches being a common symptom.
Increased sun exposure:
Bright sunlight and glare can trigger light-sensitive headaches (e.g., migraines).
Humidity and air quality:
High humidity and poor air quality (ozone, pollution) can worsen sinus pressure and headaches.

Tips to prevent heat-related headaches:
- Drink plenty of water throughout the day, even if you’re not thirsty, especially if you’re outside or active.
- Avoid the hottest part of the day, usually between 11 a.m. and 4 p.m.
- Stay in the shade or indoors when it’s very hot.
