I've found that when I have to work in uncomfortably cold temperatures, wearing a dust has a positive impact on how cold I feel. It seems to capture the heat in my breath on the exhale and pre-warm the cold the air on the inhale. The condensation that forms in the mask acts as a heat sink.
I also find that a pair of thin nitrile (or latex) gloves worn under my work gloves slows the evaporative cooling of water vapor leaving my hands, and makes any gloves feel warmer. For me, these two "tricks" really make a big difference.
