The seasonal chill becomes synonymous with restraint from arousal. Heat, the process of warming your body when you come into the heat, becomes linked to horny desire. When chilly air leaves your body, restraint from arousal goes with it, turning the now-warm listener on. Aroused, craving pleasure, losing oneself in it when safe after returning from the chill. For listeners with vaginas. Lingering effects? Maybe a bit turned on after shoveling the walk out in the cold.
