I am not saying this is the case (just an FYI) but prolonged electrolyte use can lead to kidney issues. I do it in the summer as well but also provide fresh plain water. Unless I’m doing Corid I always offer a doctored water whether that be ACV, vitamins or electrolytes and a plain water. That way they have a choice. I haven’t had to do it where I live now but when I lived in Utah I would occasionally add something in the summer.
