Migraine sufferers perceive and react more quickly to stimuli. They continuously absorb recurring stimuli and find it difficult to block them out. Anything that happens too quickly, too suddenly, or too frequently can trigger migraine attacks. This is the common thread running through many triggers.
The nervous system, which already operates very quickly due to genetic predisposition, reaches its limit, creating an energy deficit in the nerve cells. The brain then attempts to compensate for this deficit through a protective mechanism: intense cravings for high-calorie foods.
This is why many people report experiencing uncontrollable cravings before a migraine. They might eat chocolate or a cheese sandwich, for example, and then think the next day: "Aha, I ate this or that, and that triggered it."
However, these cravings are actually a protective mechanism. It's important to give in to these carbohydrate cravings and replenish the nervous system regularly.
The brain essentially needs three things: carbohydrates, water, and oxygen. If one of these resources is insufficient or depleted too quickly—for example, due to stress, overactivity, skipping meals, insufficient fluid intake, or being in poorly ventilated rooms—a deficiency can occur, potentially leading to migraine attacks caused by an insufficient energy supply to the nerve cells.
