This question is pretty dumb... I feel like if he was running 12 miles obviously his SymNS will be thru the roof already. My thinking was that the lightheadedness may be the result of sympathetic fatgue, and hence, could fall.
Obviously, ParaNS activity and Carotid impulse will decrease... But those who run know the bear of running long distances on a hot day.
