I have exercise induced (it appears) low blood pressure. After a walk with my dog, it tends to be quite low, the lowest being 63/43 with pulse 85. I react to pharmaceuticals and chemicals in general, so I've been adding a good salt to my drinking water, staying well hydrated, and am taking supplements that are supposed to help with cardiovascular stuff: B-12, magnesium, potassium, Vitamins D3 and K2, and electrolytes. From a heatstroke I suffered three years ago, I am extremely sensitive to heat, as well as cold (low bp). Otherwise, I'm a pretty healthy 74 year old female. But I'm scared to go out on a hike or out in the sun for any event for fear of lowering my bp too much and getting light-headed. So far, I haven't passed out. Is there anyone who has experience with this? Help?
