Why arm cold to touch rest of body feels warm?

When your arm feels cold to the touch while the rest of your body feels warm, it may be due to reduced blood circulation in that area, which can be caused by various factors such as constricted blood vessels or nerve compression. Additionally, the body prioritizes blood flow to vital organs and the core during colder temperatures, leaving extremities like the arms and hands feeling cooler. Environmental factors or a localized injury can also contribute to this sensation.
