I feel itchy on my body, why doesn t it itch when I get some cold water?

We will have a lot of itchy times in life, for example, some people will itch when they are allergic, their body will itch, and they will itch when they are bitten by mosquitoes in summer, but sometimes we will be outside, even if it is very itchy, we don't have some ointments or liquids and other medicines that can relieve itching, so we can only pat cold water on the itchy placeMany people will ask, why does it not itch when you feel itchy on your body? This is because the cold water temperature is lower than our body temperature, which can numb our nerves, so that the itch of ** cannot be transmitted to the brain, and we feel less itchy.

In winter, we should all have such a feeling, our hands have been placed outside, because the temperature in the air is too low, so the hands lose consciousness, the itch on the body is not itchy with cold water is the same principle, we can feel the itch because our nerves have been conveying the feeling on the **, but dipped in cold water lower than our body temperature, the blood flow rate of our body will slow down, our nerves have a certain degree of numbness, and the itch on the ** is transmitted slowly, so we don't feel so itchy.

And there are many times when we feel itchy, and the itchy area usually heats up.

There is athlete's foot. People should have a deep understanding that as soon as beriberi attack, it will be very itchy, people often say that the more you scratch, the more itchy, but the beriberi attack we will itch if we don't scratch, and it will become more and more hot, but at this time, as long as we give our feet a cold water, the itch on our feet will be instantly relieved, and the same is true for the body, and the itch on our body will also be relieved.

However, the itch is actually better not to experience this feeling, because of the willpower.

Bad people, itching is a big problem, they will not be able to control to scratch, this is very hurtful, and it is easy to make the itch back, our wounds will not heal for a while, the final result is intensifying, so try to avoid making yourself feel itchy, or if itchy, don't scratch, just pat it with cold water.

This should be dermatitis caused by allergies, don't eat fish and shrimp, and eat some light and oral anti-allergy drugs recently.

Because the temperature of cold water is low, it can paralyze our nervous system, so that we do not feel the itchy sensation.

Because the temperature of cold water is relatively low, it can play a calming role, which will temporarily reduce the degree of itching.

Analysis: You should have a disease like urticaria.

If itching is itching, fishing is pain, in fact, itching and pain They are independent nerves, just like the previous laughing punishment, that is, the punishment of itching prisoners, itching is also a kind of "pain", why fishing is pain, for example, if you fish a place that is not itchy, the actual feeling is pain. The harder you push, the more it hurts. Professional words can't be written.

Let's use an analogy, such as itching is negative, pain is positive, when it's itchy. With the right amount of pain, the positive and negative are offset. So fishing can stop itching,

When you scratch it, it compresses the nerve and slows down the conduction velocity of positive and negative electricity in the nerve endings, which can only relieve itching for a while.

I also think there's a reason: it's scratching the fungus here. Makes sense, right?

Itching is also an impulse at the end of the nerves, but it is not initiated by the central nervous system, and the impulse is terminated by scratching, and it is not itchy, personal understanding! I can't even say it myself, the master is coming!

It's all normal physiology, nothing.

This problem is generally difficult!!

When I scratched it, I killed the little bugs.

This is an interesting question.

Looking forward to the masters.
