In my experience 60 is cold no matter what. But feeling cold at 70 degrees stinks.
In England or Ireland? Ya, damp all the time all winter. It just depends on the environment. (don't want anymore moisture in the air)
Also, I'm not sure if there is an easy way to actually increase humidity without reducing the temperature. From my experience, increasing humidity while keeping the overall temperature at the same time requires additional energy.
Also, less humid air may allow you to actually wear less cloths as it is more difficult for the air to get energy off your body.
So, in that environment adding moisture makes the air warmer. (with proper heating of course)
