What are the common causes of hot hands and feet?

Your hands and feet might feel hot because your body adjusts blood flow to help keep you at a stable temperature. When your body heats up, blood vessels in your hands and feet dilate to let warm blood reach the skin, making these areas feel warmer. This is a normal part of temperature regulation. Sometimes, if the nerves that control these vessels are especially active, you might feel extra warmth.

In other cases, a condition called palmar hyperhidrosis—where the sweat glands are overactive—can also make your hands feel hot. Hand-foot syndrome is another example; it is a reaction that can occur with certain medications, and it makes the palms and soles red, hot, and sometimes painful. Additionally, studies show that responses to cold exposure can vary between individuals, meaning that your hands and feet might be more sensitive to changes in temperature.
