Should people scratch the itch?

Itching usually prompts scratching, which can sometimes lead to a vicious itch-scratch cycle. Scratching can initially feel satisfying, but prolonged scratching just leaves you with irritated skin that can still itch and often worsens the itching itself. Since scratching provides only temporary relief and doesn't promote healing of the underlying problem, it is best to avoid scratching if at all possible. If scratching breaks open the skin, bacterial infection can set in. This is known as secondary infection. And if scratching continues for many months or years, the area that is scratched may develop thickened skin (lichenification) or pigmentation that darkens the area.

The best way to allow irritated skin to heal is to stop scratching it. However, willpower often is not enough since the urge to scratch can be compelling. The following sections discuss some general measures and home remedies to help to stop scratching and control itch, regardless of the cause.
