Why do parents think movement will warm up their children?

Parents often believe that movement will warm up their children because physical activity increases blood circulation and generates body heat. Engaging in movement, such as running or playing, raises a child's heart rate and metabolism, leading to a natural warming effect. Additionally, parents may associate active play with warmth, recalling their own experiences or observing how children seem to feel warmer after being active. This instinctive understanding prompts parents to encourage movement as a way to keep their children comfortable in cooler conditions.
