Answer 1

From a physiological perspective, if a person perspires in cold weather, the reasons for the same might be — (a) high blood pressure (b) Hyper tension (c) Cardiac arrest . From a dermatological view point, the reason behind his perspiration is that our hypothalamus detects the drop in the blood temperature and produces responses. Our body starts secreting adrenaline hormone which increases the metabolic rate and in turn increases the heat production.

Fever and sickness or any kind of vigorous activity can lead to perspiration even in cold outside...
