What is the reason why the saddle bottom of a bicycle or motorcycle that is burned by the sun itches?

When you sit on a bicycle or motorcycle that is scalded by the sun, your saddle butt will itch. There may be the following reasons:

1. Skin sensitivity: It may cause allergic reaction to articles exposed to the sun, resulting in itching and pain.

2. Burn: If the skin is exposed to the sun for a long time and sits on a hot bicycle or motorcycle seat, the skin may be burned, causing itching and pain.

3. Cushion material: If the cushion is made of black cloth or leather, it is likely to absorb the heat of the sun, resulting in hip burns.

If this happens frequently, it is recommended to seek medical advice to determine the potential causes and take appropriate treatment measures.
