When skin is burned, it turns white because of the damage done to the blood vessels.
How Burns Affect Blood Vessels
- Blood Vessels: Our skin contains a network of tiny blood vessels called capillaries that carry oxygen-rich blood to the surface. This gives our skin its natural color.
- Heat Damage: When skin is exposed to extreme heat, the capillaries constrict, reducing blood flow to the area.
- Loss of Color: This constriction causes the skin to appear pale or white because less blood is reaching the surface.
Types of Burns
Burns can be classified into three main types based on their severity:
- First-degree burns: These are the least severe and affect only the outer layer of skin. They usually cause redness and pain, but the skin does not turn white.
- Second-degree burns: These burns affect the deeper layers of skin and cause blistering, pain, and swelling. The skin may turn white or red.
- Third-degree burns: These are the most severe burns and affect all layers of skin and sometimes even the underlying tissues. The skin may appear white, charred, or leathery.
Importance of First Aid
It is important to seek medical attention for any burn, especially if it is severe. Proper first aid can minimize damage and promote healing.
Conclusion
Skin turns white when burned because the heat damage causes blood vessels to constrict, reducing blood flow to the affected area. This makes the skin appear pale or white due to the lack of oxygen-rich blood reaching the surface.
