A lot of offices (including home offices) are cheap when it comes to cranking the heat. A blanket and mittens may look funny, but you can gift a little warmth with the Warm Mouse. The company says that it can improve circulation, reduce Carpal Tunnel symptoms, and emits infrared rays that can produce better enzymes within muscle cells. Superpowers aside, we just love that this 800 dpi, optical 2-button scrolling mouse can make one hand a little sweaty as the rest of the human body turns blue. It works with any PC, Mac, and even a laptop.
