I am a member of a living history group that does a lot of camping, often in warmer weather. Our costumes often involve wearing woolen outfits, though we also use cotton and flannel look-alikes to stay cooler. I am on diuretic medications for hypertension, and I am also a diabetic, and I discover that I am having a hard time staying hydrated, and come home tired, sick, and mentally out of sorts, despite constantly drinking water. I don’t really feel the effects until I’ve returned to my climate-controlled home. A couple of times I have missed work due to feeling ill as a result. We rough it while camping as much as possible. I would appreciate any suggestions of how I can keep myself hydrated and keep my electrolytes up while staying in my period-appropriate character (for example, I can’t walk around with a big bottle of Gatorade in front of patrons, for such did not exist in 1630, and cooler space is at a premium).
