Spending time outdoors in the summer can be refreshing– but it can also lead to heat-related health issues if you’re not careful. One of the most common early symptoms of heat exhaustion is a pounding headache that doesn’t seem to go away.

What Causes a Headache From Heat Exhaustion?
A headache due to heat exhaustion happens when your body becomes dehydrated and overheated. Prolonged exposure to hot, humid conditions– especially while exercising, working, or not drinking enough fluids– can overwhelm your body’s cooling system. This can lead to:
- Dehydration and electrolyte imbalance
- Dilation of blood vessels in the brain
- Muscle tension from physical stress or sun exposure
All of these factors can trigger a throbbing or pressure-like headache, often accompanied by fatigue, dizziness, nausea, or muscle cramps.
How Long Do These Headaches Last?
In most cases, a headache from heat exhaustion will begin to improve within 30 minutes to 1 hour once your body starts cooling and rehydration. However, without proper rest and fluids, the headache can last several hours, worsen with continued heat exposure, and persist into the following day if dehydration is not addressed. If symptoms are severe or do not improve within a few hours of treatment, it may be a sign of heat stroke or another serious condition requiring medical attention.
How To Treat a Heat-Related Headache at Home
If you suspect your headache is caused by heat exhaustion, act quickly. You should:
- Get out of the heat immediately. Move to an air-conditioned or shaded area.
- Hydrate! Drink water or an electrolyte drink slowly.
- Cool your body. Use a cold compress on your forehead or the back of your neck.
- Rest and relax. Lie down and avoid physical activity until your symptoms improve.
- Take over-the-counter medication. It can help relieve your headache pain.
When To Visit Urgent Care For a Heat Headache
A mild headache from heat exhaustion typically improves within a few hours, but you should visit urgent care if you experience a persistent headache that lasts more than a few hours, even after rest and hydration. Seek medical care if you experience nausea, vomiting, muscle weakness or cramps, dizziness, or a high fever. These may be signs of severe heat exhaustion or heat stroke, which requires prompt medical treatment.
