Why do relieve itching scratching?

Have you ever wondered why your body feels itchy? For a long time, even scientists have had difficulty interpreting the cause of itching , but now they have found it.

Why do people scratch when itching?

Feeling itchy somewhere on the body is extremely uncomfortable, but it is actually an important function of the body, protecting the skin from harm. However, scientists still have a headache to explain what really makes itchy, why there are things when it comes to itching and other things don't.

Recently, a new study on Oxford University mice, lit a light to see what happens in the human body when we feel itchy. This study, when published, can cure thousands of people who are experiencing chronic itching.

Causes from body hair

Itching often occurs when there is a slight impact on the hair on the skin. This makes you move your hand to the right place and scratch it. It may seem unconscious, but such simple actions are an effective way to protect your skin from damage from the external environment, usually insects and parasites.

This protective action comes from the obvious thing, when scratching, you can cut anything that is on your skin and cause itching - as simple as a mosquito bite, the mosquito perches on your hand. and the injection makes us scratch the spot to chase the blood sucker. The human body is intelligent, isn't it?

But not anything that rubs on the skin makes us scratch crazy. Take, for example, clothes, things that come in constant contact with your body. If all contact causes itching, you can only spend the whole day scratching. So how can the body know exactly what sensation is supposed to be itching, to give scratching reflexes, and other bumps?

Recent research is really important when it has begun to reveal the secret of this process. It shows us a specific group of cells, a population of 'cells that inhibit spinal nerve ', which are present in the spine and act as a connection door between the brain and body skin. These cells are responsible for allowing the sensation of itching to be carried to the brain or inhibiting those signals to prevent them from reaching your brain.

Chronic pruritus, exogenous, pruritus itching

The researchers bred the mice, making the cells selectively flawed, they realized, the signs of the itching of the mice were amazingly expressed. There are poor mice who have to spit their feathers themselves. Such manifestations show symptoms of chronic pruritus , currently 8.4% of the world's population is infected with the disease.

This study also shows that if these results are applied in the human body, chronic itching may be due to certain shortcomings in the spinal cord's special cells. This will probably be the goal to find the remedy, in the future, for those who are daily experiencing chronic itching.
Not only did this study show that while the itching caused by slight bumps on the mice was interrupted, there was no change in the way they responded to the itch that had an inflammatory reaction. irritation, such as mosquito bites.

What is this remarkable about? Because even though both types of itching feel the same, your body sends separate information about the types that cause itching to the brain, in different ways. The researchers call these cells " brains of the spine" because they are evidence of how the human nervous system can produce very complex behaviors without the need for a sense of control. .

Mice express perfectly normal with painful touches. Interestingly, previous research, by St. John's Medical University. Thomas, showed a complex link between exogenous itching (like insect bites) with a sense of pain. They point out that a collision causes pain or heat, burns can dispel the exogenous itching sensation (not a very good exchange). Therefore, that is why you feel better when scratching a rash. The pain of scratching reduces the itching feeling. Sadly, this effect is only temporary.

Surprisingly, there is evidence that the feeling of itching is not just a process that occurs on your skin, sometimes even because of psychological factors. There have been records of 'Itching' when just looking at others scratching can make a person feel like an itch spread. In fact, a recent study, from Wake Forest University of Medicine and Pharmacy, showed that just by stimulation through images or sounds related to scratching can also make the scratching behavior increase dramatically. on the participants.

Until now, the agent of pruritus as well as the body's mechanism of action to prevent it has always been an endless topic, without a detailed solution. However, did you feel a bit itchy on your body when you came here?
