Itching, also known as pruritus, is an unpleasant sensation that can be caused by a variety of factors. While it can be a nuisance, it can also be a symptom of an underlying medical condition.

A recent study published in the journal Nature found that a group of neurons called sensory neurons play a key role in itching.

These neurons detect histamine, a chemical that is released by the body in response to injury or inflammation.

When histamine binds to these neurons, it triggers a signal that travels to the spinal cord and brain, where it is interpreted as itching.

Treating Itchiness The treatment for itching depends on the underlying cause. In some cases, over-the-counter medications such as antihistamines or corticosteroids can be helpful.

In other cases, prescription medications or treatment for the underlying medical condition may be necessary.

It is important to see a doctor if your itching is severe, persistent, or interferes with your daily life. Source:
