Nineteen degrees indoors
Short answer: Nineteen degrees is comfortable when you move and cold when you sit still. The answer is an extra layer on the upper body, not more heating.
Why it feels cold sitting down
When you sit still, the body's heat production drops. At the same time the air around you cools the skin constantly. After twenty minutes without moving, most people notice it.
What works
A long sleeved layer under what you are wearing, and something on your feet. Bamboo viscose against the skin holds body heat without making you hot when you stand up. See bamboo long sleeved t-shirts for men.
Feet are the key
Cold feet make the whole body feel cold. A pair of proper socks does more than a degree on the thermostat. See bamboo socks for women and bamboo sweatshirts for women.
