Spending time in the sun or exercising on a hot day can leave you feeling exhausted, and sometimes with a pounding headache. While many people associate heat with sunburn or dehydration, few realize that a heat-related headache is one of the earliest signs your body is struggling to cope with high temperatures. So, how long does a heat-related headache last? The answer depends on the cause, the severity of symptoms, and how quickly you act to cool yourself down and rehydrate.

What Causes Heat-Related Headaches?
A headache that occurs due to heat is often triggered by one or more of the following:
- Dehydration: When your body loses more fluids than it takes in, your brain can temporarily contract due to fluid loss, leading to pain or pressure.
- Overheating: Prolonged exposure to high temperatures can cause your body to struggle with temperature regulation, leading to fatigue, dizziness, and headaches.
- Electrolyte Imbalance: Sweat contains vital minerals like sodium and potassium. Losing these through sweat without replacing them can affect nerve and muscle function– including those in your head and neck.
- Sun Exposure: Bright sunlight and UV rays can lead to sun-induced migraines or tension headaches, especially if you’re not wearing sunglasses or protective headwear.
How Long Do Heat-Induced Headaches Last?
In most cases, a heat-related headache lasts between 1 to 3 hours once you begin to rehydrate, rest, and cool off. However, the duration can vary. Mild headaches may resolve quickly after drinking water, getting into shade, or applying a cool compress. Moderate to severe headaches may persist for several hours, especially if dehydration or electrolyte loss was significant. If associated with heat exhaustion, symptoms may last longer (up to 24 hours) and be accompanied by nausea, dizziness, or fatigue. If symptoms worsen or don’t go away, it may be a sign of heat stroke, migraine, or another condition requiring medical attention.
How To Relieve a Heat Headache
If you begin experiencing a headache in warm weather or during physical activity, take these steps:
- Hydrate immediately with water or an electrolyte-replenishing sports drink
- Rest in a cool, shaded, or air-conditioned space
- Apply a cold compress or damp towel to your forehead and neck
- Take an over-the-counter pain reliever if needed
An urgent care provider can assess your symptoms, provide treatment, and rule out more serious conditions like heat stroke or migraines.
