Short-of-breath, heart pounding/ &or lighthead => mental fog
Posted: Mon Jun 24, 2013 4:26 pm
I sometimes find myself out-of-breath, breathing heavily, and I sit down and notice my heart is racing a bit. It's as if I'd run up a hill, when all I did was sweep the kitchen. And sometimes there's some lightheadedness or disequilibrium. These aren't necessarily just side effects arising from the muscles trembling. It seems I have some "orthostatic intolerance" (OI) which is a malfunction of the cerebellum &/or brainstem. Almost certainly the cause of OI is somehow related to the cause of OT.
The forum has lots of folks commenting on general fatigue and incapacity. If you search our forum for "heart pounding" or "out-of-breath", you'll find plenty of entries. We notice things are worsened by anxiety and/or shallow breathing &/or overworking muscles &/or discouragement &/or low blood sugar. AND it's worth noticing that many of us might be struggling with Orthostatic Intolerance, which is it's own medical phenomena.
Here's some info:

I think our susceptibility to adrenaline is related also. "Dysautonomia" is the broad category that encompasses Orthostatic Intolerance. I'm too 'wired', physically high-strung (even though often fatigued). My sympathetic nervous system (the alerting adrenaline system) is over-active. My para-sympathetic nervous system (the relaxation system) seems like the underdog.
Here are some quotes from the second article above: "Following the episodes of lightheadedness, most people feel tired for several hours (sometimes lasting more than a day) and their thinking can be somewhat foggy." "The mental confusion takes the form of difficulty concentrating, staying on task, paying attention, remembering, or finding the right words. Some describe being in a “mental fog.” Some develop worse fatigue after mentally demanding activities, such as reading and concentrating. This may occur because the blood vessels of the limbs dilate rather than constrict in response to mental tasks, allowing more blood to pool. In persons with POTS (a type of Orthostatic Intolerance), a fast heart rate is a defining feature, and awareness of vigorous or skipped heart beats (palpitations) is common. In addition, patients can experience lightheadedness, intolerance of exercise, fatigue, visual blurring, weakness, imbalance, headaches, shakiness, clamminess, anxiety, shortness of breath, and the same type of mental fogginess previously described."
