Why do your upper arms get cold?

Cold upper arms can result from several factors, including poor circulation, exposure to cold temperatures, or inadequate insulation from clothing. When blood flow is reduced, especially in response to cold environments, the body prioritizes warmth for vital organs, causing extremities to feel cooler. Additionally, sweating or wet clothing can also lead to a chill in the upper arms. If this sensation persists, it may be worth consulting a healthcare professional.
