Folks who have not had any formal preparation to be in hot places, often are unaware they need to keep an eye on their urine color, and if it is any darker than "pale", they probably need to hydrate. They can also do a finger pinch, pinch up a fold of skin on the back of a knuckle. If the skin stays "up" and doesn't go back down right away? That's dehydration, too. (Relative to their own "normal", not necessarily to each other.)
Probably not "heatsickness" in November while it was raining and blowing in the 20s up here.
With wind chill it was well below freezing. We were all a bit too concerned with huddling in place and just didn't "feel" hungry or thirsty. Agreed about the signs of dehydration as well. For me, the low grade nausea made me think that eating or drinking would result in puking, which (honestly) I just didn't want to do in front of the other crew because I'd loose face as the liveabard guy who got seasick.
I should have just eaten, hydrated (you're right it would have been a great time for the oral rehydration salts) and if it came back up, then so be it. If it stayed back down, I would have been cured.
