You got that right. When the temperatures drop outside, you sweat less. The heat and humidity can really take a toll on your body, requiring you to drink more water to stay hydrated. I mean, who really enjoys wearing moist, sticky clothing? It is much cooler and drier in the fall. The brisk winds keep the air circulating, keeping you cooler as your body temperature naturally rises while hiking.
Cooler nights are also brought forth due to the shortened days of autumn. These cooler nights make it more comfortable to sleep. Haven’t you realized that you seem to toss and turn more often when it’s too hot at night? Cooler temperatures at night allow your body to stay cool, and able to stay rested longer.
The cooler air also helps to keep your water stay colder longer. Who likes drinking warm water from their hydration pack? I don’t really see anyone jumping up and down, hands waving in the air, screaming “me, me, me, I do, I do, I do!”
