People are pretty consistent because it's a known physiological reaction. Cold hands and feet are almost always a sign of poor blood flow in extremities, Making the heart beat faster (ex: doing 15 pushups/jumping jacks) helps the most. Decreasing blood vessel constriction helps as well (increasing core temp/ decreasing heat loss). Alcohol has a similar effect, and will increase blood flow to the extremities and increase heartrate - this is why it's so commonly thought to warm you up (note - it's not, it's just increasing blood flow and getting it to your hands/feet more quickly & easily) Unfortunately - no one is identical, reynauds is a condition where folks have an extreme version of the constriction of the blood vessels in their hands/feet in response to cold. You may be farther along that scale.
