KOMPAS.com – When the itching burns, the things we will do automatically are scratching the part of the skin itch. Behind the usual habits we often do, there seems to be a relationship between scratching and brain performance.
Here are 11 facts about scratching that we can not know or even imagine.
1. On average we are scratched 97 times a day
Maybe I never counted scratching my skin every day. One study found, on average, that people scratched their skin up to 100 times a day.
Now you could do it. Please scratch, no one is looking.

2. Itching because animals and plants are triggered by toxins on the skin
When you feel itchy because of contact with an animal or a plant, it is actually triggered by toxins on the skin.
Toxin begins secretion of histamine, part of the immune response of the body. This causes nerve fibers to send itch signals to the brain.
3. itching has its own neural network
Previously I thought itching and pain shared the same path. Until 1997, itching had its own nerve fibers.
4. The itchy signs move more slowly
All nerve fibers have different speeds.
321 km / h for the speed signal.
The pain that feels right when you accidentally hit a hot stove reaches 128 km per hour.
Eating moves at a speed of only 2 mph or 3 km per hour, slower than the speed of a person walking.
5. Contagious itching, just like yawning
Scientists prove this by showing videos of mice watching other scratching mice.
When the first group scratched, the other mice that followed were joined in scratches.
6. Contagious scratches involve a small part of the brain called the suprachiasmatic nucleus
Parts of the brain called the suprachiasmatic nucleus are strongly suspected of being involved in this. However, neuroscientists still do not know how this part of the brain is involved in seeing and spreading scratching.
7. The best way to get rid of itching
Scratching is the best way to make your body deal with the "invaders" that cause itching.
This helps eliminate annoying insects or poisonous plants.
Garukan also dilates blood vessels, making the flow of white blood cells and plasma to remove the toxins that come into contact.
This is what causes the skin to become red and colorful.
8. Scratching feels good because it releases serotonin in the brain
Serotonin is a neurotransmitter that scientists see happily.
The more serotonin is flowing into your body, the happier you are. It is not surprising that sometimes it is difficult for us to stop scratching.
9. The best place to be scratched is the ankle
According to a study published on British Journal of Dermatology in 2012, itching felt most often in the ankles.
This place is also a joy of scratching and is usually the longest done.
Honestly, have you scratched your ankle to make sure?
10. The more you write, the more itches
Beware of cycling and scratching!
Scratching the skin releases additional histamine, sending more hemorrhagic signals to the brain.
If you do too much, the skin will break, the risk of infection and scabies.

11. itchy cicatrization cycle
The cicatrization cycle is a problem facing skin diseases such as psoriasis and eczema
Antihistamines are often administered to try to reduce the influence of histamine and to overcome itching.
12. Chronic itching is as exhausting as chronic pain
Researchers in the medical field find that those who suffer from tedious tears have the same level of discomfort and depression as patients with chronic illness.
According to a study published in the Archives of Dermatology, people who suffer from itching for weeks or even years suffer from problems as severe as those with chronic pain.
In fact, the authors of the study say the chronic itching is "the same as the pain experienced by the skin."
And not only that – the persistent eagerness should be ignored. Chronic eczema is associated with various diseases, such as liver problems and lymphoma.
