Insulation

Notes from Janice’s Desk

My hands and feet are generally cold to the touch. In fact, when I shake hands I often hear–“Cold hands warm heart.” The saying indicates that because my hands are cold I have compassion for others. That is a character trait that I try to develop, but do people really think I am compassionate just because my hands are cold? It makes more sense that I’d be cold toward people.  Scientists at Yale University designed a test to determine  if physical warmth promotes positive feelings toward others. For the full report about the their test and results, see COLD HANDS WARM HEART.

So why are my hands so cold? Circulation is part of the problem, but no matter my body weight, my hands are always thin. I call them bony–no fat. One good thing is that my rings fit regardless of how large or small the rest of my body is. But, the lack of fat in my hands contributes to their losing heat, thus making them feel cold. For information about how fat keeps our bodies warm, see INSULATION
