• A dysautonomia patient with severe heat intolerance reported that “my summer cooling vest and the misting fan and the umbrella” were essential equipment for brief outdoor tasks, and without the full cooling stack even fifteen minutes outside required more than an hour of indoor recovery Reddit.
  
  

Negatives
