KOMPAS.com – When itching spreads, what we will automatically do is scratch the part of the itching of the skin. Above the common habits we often do, it turns out that there is a connection between scratching and performance of the brain.
Here are 11 scratch facts that we may not be aware of and never imagined.
1. On average we scratch 97 times a day
We may never have thought how much we warm our skin many times a day. One study found that, on average, people scratch the skin up to 100 times a day.
Right now you can do this. Please, wait, nobody sees it.

2. Itching, because animals and plants are activated from toxins on the skin
When you feel nervous about contacting an animal or plant, it is actually caused by skin toxins.
Toxin starts secreting histamine, part of the immune response to the body. This causes the nerve fibers to send nervous signals to the brain.
3. Itching has its own neural network
We previously thought that itching and pain shared the same path. It was not until 1997 that itching actually had its own nerve fibers.
4. Symptoms of itching are slower
All nerve fibers have different gears.
321 km per hour speed-touch signal.
The pain immediately felt, when you accidentally touch a hot oven, reacts at 128 kilometers per hour.
Well, itching moves at a speed of only 2 km / h or 3 km per hour, slower than the speed of walking on the face.
5. Contagious itching, just like yawning
Scientists prove this by showing video footage of mice watching other mice scratching.
When the first group was scratched, other mice who watched joined together in scratching.
6. Infectious scratches involve a small part of the brain called suprachiasmatic nucleus
Parts of the brain called suprachiasmatic nucleus are strongly suspected of being involved in this. However, neurologists still do not know how this part of the brain is involved in seeing and spreading scrapes.
7. The best way to get rid of itching
Scratching is the best way for the body to deal with "invaders" that cause itching.
This helps to get rid of boring insects or poisonous plants.
Garukan also makes dilatation of the blood vessels, making white blood cells and plasma flow to expel the recessed toxins.
This is what causes the skin to become red and stain.
8. Scratching feels good because it releases serotonin in the brain
Serotonin is a neurotransmitter that scientists see for pleasure.
The more serotonin flows into your body, the happier you are. Not surprisingly, it is sometimes difficult for us to stop weeping.
9. The best place for scratching is the ankle
According to a study published on British Journal of Dermatology in 2012, itching most often felt the ankles.
This place is also a point of enjoying the feeling of scratching and is usually the longest.
Honestly, did you just scratch your ankle to make sure?
10. The more you scratch, the more you get it
Beware of scratching and scratching cycles!
Scratching the skin releases additional histamine, sending more nervous signals to the brain.
If you do too much, the skin will break, the risk of infection and cause scabies.

11. Sensitive scratch cycle
The itching and itching cycle is a problem with skin diseases such as psoriasis and eczema
Antihistamines are often given to reduce the effect of histamine and overcome itching.
12. Chronic itching is as exhausting as chronic pain
Medical researchers believe that people suffering from ruthless tears experience the same level of discomfort and depression as patients with chronic illness.
According to a study published in the Dermatology Archives, people suffering from itching for weeks or even years experience problems as serious as those with chronic pain.
In fact, the authors of the study say that chronic itching is "just like the pain that the skin experiences."
And not only that, – a continuing itching should be ignored. Chronic itching is associated with various diseases such as liver problems and lymphoma.
