Summary

Story at-a-glance

Exercise headaches affect up to 26% of adults and occur even when properly hydrated, often due to how the brain manages heat during physical exertion
Your brain cools itself by increasing blood flow, which raises pressure in your skull that triggers headaches, especially if you're new to exercise or increase intensity too quickly
Warning signs include vision problems, nausea or thunderclap headaches that come on suddenly; these require medical evaluation to rule out serious conditions
Prevention strategies include warming up slowly, staying well-hydrated before and during workouts, exercising in cool environments and gradually building fitness levels
Most exercise headaches are harmless and typically improve over time as your cardiovascular system adapts to physical stress

0:19.7	headache slam you minutes later,
0:21.6	forcing you to squat on the asphalt, with your eyelids clenched, and wonder what just happened to your body.
0:27.6	Welcome to Dr. Mercola's cellular wisdom. I'm Ethan Foster, and with me is Alara Sky.
0:33.6	Today we're dissecting why these exertion headaches occur, how they differ from ordinary
0:39.1	tension pain, and what evidence-backed adjustments allow you to keep moving without fearing the next
0:44.7	pulse of pain. I'm glad to guide the discussion, Ethan. We'll stick strictly to findings in Dr.
0:50.3	Mercola's article, focusing on heat management in your brain, pressure spikes inside your skull,
0:56.3	and the specific warning signs that mean you should seek medical evaluation before the next
1:00.6	set of burpees. Let's begin with the spark itself. During vigorous movement, your brain generates
1:06.4	heat, yet can't sweat or vent it directly. To cool down, it rerouts extra blood upward, raising
1:12.9	intracranial pressure. If that increase happens faster than your vessels can adapt, pain
1:17.8	receptors fire, and you feel a sharp, pulsing ache on both sides. Hydration helps your
1:23.6	cardiovascular system work efficiently, but the article makes clear it isn't the root
1:27.7	trigger. Even perfectly hydrated athletes can suffer because the primary driver is that rapid,
1:33.5	heat-related surge of blood to your head, particularly when workout intensity jumps without
1:38.5	a runway. Conditioning plays a decisive role. People new to strenuous exercise, or those returning after
1:45.3	a long sedentary stretch, have vessels that haven't practiced controlled dilation and contraction.
1:52.2	Consistent gradual training progressively retrain those vessels to handle surges with less pressure
