Needing to hydrate isn’t an indicator of impending heat exhaustion. I mean, people need to hydrate sometimes in cool weather. The Mayo Clinic doesn’t list needing to hydrate as one of the symptoms to be on the lookout for.
I’m not a doctor. I’m just surmising that if you aren’t drenched in sweat because it has evaporated so fast that one might not be aware of impending heat exhaustion. Obviously I might be wrong. Heavy sweating is a possible symptom of heat exhaustion.
Edit: At the end it does list dehydration as something to look out for. I have no idea what it is like in 110 degree weather with virtually no humidity. I’d guess even being well hydrated still makes it easy to get heat exhaustion.
