Sudden intense exercise can be a powerful way to boost fitness, but for some people, sudden exertion also brings on a pounding exertional headache or even a full-blown migraine.
When effort ramps up too quickly, rapid changes in blood flow, blood pressure, body temperature, and hydration can work together as a strong migraine trigger. Understanding how blood pressure spikes, vasodilation, dehydration, overexertion, and heat/humidity interact can help people exercise more comfortably and safely.
