What Causes Itching?

Itching, also known as pruritus, can be caused by various factors. Understanding these causes can help in managing and treating the sensation effectively.

1. Dry Skin: One of the most common causes of itching is dry skin. When skin lacks moisture, it can become tight, rough, and itchy.

2. Allergic Reactions: Allergens like pollen, pet dander, or certain foods can trigger itching. The body's immune response to these allergens often results in itchy skin.

3. Insect Bites: Mosquitoes, fleas, and other insects inject saliva into the skin, causing an itchy reaction.

The sensation of itching involves complex interactions between the skin, nerves, and brain. Here's a closer look at how it all works.

9. Nerve Endings: Specialized nerve endings in the skin detect irritants and send signals to the brain.
