Exercise is good for you, so why does it make you sick?
Aerobic exercise, like my current favorites kickboxing and squash, can significantly raise histamine levels in the body. The upside (because in my world there always is one) is that people pay good money for pharmaceutical vasodilators to lower their blood pressure. The downside (other than the spike in histamine for those of us with histaminosis/histamine intolerance), is the migraines that accompany vasodilation. I often get migraine like headaches if it’s too hot in yoga class.
