Hi ! Thanks for your query. It is normal to sweat when we exercise. It is not normal to sweat when we are sitting in an air conditioned office and we experience excessive sweating from the underarms, palms, feet or any combination of the above. Primary hyperhidrosis  is the type of hyperhidrosis that is treatable. Secondary hyperhidrosis is due to an underlying medical problem and when that medical problem is treated, it is possible that the hyperhidrosis may be lessened. What differentiates secondary hyperhidrosis from primary hyperhidrosis is that secondary hyperhidrosis is sweating which occurs throughout the body whereas primary hyperhidrosis is located in distinct parts of the body - head, underarms, palms, groin, feet, or any combination of these areas. For your problem with excessive sweating you should first try topical agents containing aluminum chloride, such as Aldry.  If these don't work, or if they cause skin irritation, then you should try Botulinum toxin injections which can ameliorate sweating for about 4 months
