What Is an Itch?

An itch can feel like a burning affect. It causes the desire or reflex to scratch. It is a slightly electrical or periodic non-painful sensation. It can be described as something crawling along the skin. It can be annoying. Finally, it is caused by stimulation of nerve cells in the skin. 

What Is Scratching?

Scratching is the act we do when our skin itches. It can feel good, yet the relief won’t last very long. 

Our muscles, joints, and organs can hurt. But our skin is the only part of our body that can feel pain and itch. 

An itch can be triggered by something outside our body. For one, poison ivy. It can also be born due to something happening on the inside. For example, psoriasis or allergies. 

Though it feels good, scratching sets mild pain in your skin. Nerve cells tell our brain that something hurts, deflecting it from the itch. It can make you feel better in the moment. Yet, 1 in 5 people say scratching makes them itch somewhere else in their body. 

Sometimes, the pain from scratching makes our body elicit the pain-fighting chemical serotonin. It can make the itch feel even itchier. It is why the more we scratch, the more we itch. The more we itch, the more we scratch. 

Why Does Scratching Feel Good? The Science of Scratching

Scratching causes the elicit of serotonin in the brain. Serotonin is a neurotransmitter. It is in control of feelings of happiness and satisfaction. 

Scratching is a type of pain. We depend on it to get rid of an itch. When we scratch, we send low-level pain signals to the brain. These pain signals distract the brain from itching temporarily. These pain signals release serotonin, which feels really, really good. 

Why Is It Instinct to Scratch an Itch?

The instinct to scratch an itch is a natural response. Our nervous system triggers it. When our skin is irritated, it sends signals to the brain that something needs attention. Scratching is an instinctive action. It gives temporary relief. It does so by stimulating nerve endings. It effectively distracts the brain from the itch sensation.
