Callus facts for kids

A callus is a part of your skin that gets thicker and harder. This happens when your skin experiences a lot of pressure, rubbing (which we call friction), or irritation over and over again. Think of it as your body's way of protecting itself! Calluses are often found on your feet because of walking or wearing shoes that don't fit well. They might not look pretty, but calluses are usually not harmful. However, if you ignore them, they can sometimes lead to other problems.

What Are Calluses?

A callus is like a natural shield your body creates. When a certain spot on your skin gets rubbed or pressed repeatedly, your body responds by making that skin tougher and thicker. This extra layer of skin helps protect the sensitive parts underneath from damage.

Where Do Calluses Form?

Calluses can show up on different parts of your body.

• On your feet: This is a very common place to find calluses. They often form on the soles of your feet, especially under the balls of your feet or on your heels. This is because of the constant pressure from walking, running, or standing. Shoes that are too tight or too loose can also cause calluses on your feet.
• On your hands: Calluses can also form on your hands. You might find them on your palms or on your fingers, especially the middle, ring, and index fingers.

What Causes Calluses?

Many everyday activities can lead to calluses.

• Sports and Activities: Playing certain sports can cause calluses. For example, gymnasts often get calluses on their hands from gripping bars. Rock climbers also develop calluses to protect their hands.
• Work and Hobbies: People who do a lot of manual labor, like construction work, often get calluses on their hands. Playing musical instruments, such as a guitar or violin, can also cause calluses on your fingertips as they press against the strings.
• Footwear: Wearing high heels too much or shoes that don't fit properly can create pressure points on your feet, leading to calluses.

Are Calluses Harmful?

Most of the time, calluses are not dangerous. They are your body's way of protecting itself. However, sometimes they can become very thick or painful. If a callus gets too big, it can press on nerves or other parts of your foot, causing discomfort. It's important to pay attention to your calluses and seek advice if they become painful or cause problems.
