The "freeze to death" risk is largely overblown. Just wear more layers of clothing, and get a few more blankets for your bed. You might be uncomfortable but you'll be fine. Heating your home to 25 C in the dead of winter so you can wear t-shirts instead of sweaters is a modern luxury, not a necessity.

Most of the deaths attributed to the cold will be noticeable only in a slight uptick of elderly people living alone dying at a higher rate than usual, followed by a dip in their death rate in the subsequent months. The years of potential lost life (YPLL) will be minimal.
