Scratching an itch is the most satisfying instant relief available, but according to a new study from Washington University School of Medicine in St. Louis, it's actually just a mental scam: scratching causes the brain to release serotonin, which intensifies the itch sensation.

Here's how it works: when something bothers the skin, like a mosquito bite, cells release a chemical, usually histamine. That release provokes the nociceptors in the skin to send a message to the spine, which then relays the message through a bundle of nerves called the spinothalamic tract up to the brain.
The proteins are foreign substances that trigger the body's immune system. To fight them the body's immune system releases histamine, a compound that helps white blood cells get to the affected area. Histamine is what causes the itchiness, inflammation, and swelling.
Common causes of pruritus on the body or the legs include: dry skin. irritation from bug bites or allergies to plants, such as poison ivy. chronic skin conditions, such as eczema and psoriasis.
Just about as common as fatigue in PBC, itching (pruritus) of the skin affects a majority of individuals at some time during the disease. The itching tends to occur early in the course of the disease, when individuals still have good liver function. As a matter of fact, itching can even be the initial symptom of PBC.
During the wound-healing process, these nerves signal the spinal cord that skin is being stimulated. The brain perceives those signals as itchy. These nerves are also sensitive to chemicals, such as histamine, which the body releases in response to an injury.

Ask the Allergist: Breaking the Itch-Scratch Cycle
- Use moisturizers.

In some cases, the skin may only feel itchier during the night because of a lack of outside distractions.
