Itching

Itching, or pruritus, is a sensation that prompts the desire to scratch. It occurs when nerve fibers in the skin are activated by various triggers, such as dry skin, allergies, irritants, infections, or certain medical conditions. This activation sends signals to the brain, creating the sensation of itchiness. It can be localized or widespread and may be temporary or chronic. Addressing the underlying cause, keeping skin moisturized, or using medications can help alleviate itching. Understanding that itching is a response to skin irritation helps in managing and treating it effectively.
