Answer:
When you walk barefoot on the beach you can feel the sand is hit , the heat energy from the sand is conducted to your feet, causing them to feel hot and potentially uncomfortable or painful. The sensation of burning is a result of the intense heat that your feet are exposed to while walking on the heated surface.To alleviate this discomfort, you can try wearing sandals or using a towel or beach mat to create a barrier between your feet and the hot sand. Walking in shaded areas or wetting your feet in the water can also provide some relief by cooling down the skin.
