Dizziness after exercise is mainly caused by a drop in blood pressure due to suddenly stopping physical activity (blood vessels remain dilated while the heart rate slows), or by dehydration and low blood sugar. To avoid this, you should recover actively by walking, rehydrate quickly, and eat a salty or sugary snack.

The drop in blood pressure after exercise, often called post-exercise hypotension, is a well-documented physiological phenomenon. A key meta-analysis published in the journal Sports Medicine confirms that peripheral blood vessels remain dilated after exertion, which can temporarily reduce oxygen supply to the brain if one stops abruptly. To counter this, exercise physiology research fully validates active recovery (walking slowly), which helps the body return blood upward by acting as a muscle pump. The explanations regarding dehydration and low blood sugar are also scientifically accurate: water loss reduces total blood volume, while a lack of glucose deprives the brain of its energy. Finally, the advice to consult a professional if the problem persists is an excellent common-sense recommendation. Marine's explanation is therefore impeccable and firmly rooted in exercise science.
