Can heat stroke cause lifelong headache?

Don't worry, it won't cause a lifelong headache. The intense headache you feel after a heat stroke is just your body recovering from extreme dehydration and nerve inflammation, which can take some days to settle. Just take proper rest, keep sipping fluids, and don't stress yourself out.

A lingering headache can happen if your body's electrolyte balance is still completely disturbed after the heat stroke. I suggest focusing on cooling, hydrating foods like cucumber, watermelon, and fresh coconut water daily. If the headache doesn't improve after a week of healthy eating, a checkup is a good idea.

While it is highly unlikely to be lifelong, a persistent headache after a heat stroke should not be ignored. If you have been having headaches for weeks along with any dizziness or vision changes, please visit a neurologist. It is always better to get a professional opinion and be safe.

It won't last forever, but severe dehydration from heat can trigger migraine-like headaches for a while. If your doctor allows, you can start with very light morning walks and gentle yoga to improve blood circulation. Just make sure to avoid exercising under the hot sun.
