Why Do We Feel Itchy

Our skin is the largest organ that we have, and we put it through several potential irritants knowingly or rather unknowingly. It just happens! With so many pollutants, toxins and irritants in the air, our skin comes in contact with daily. No wonder we are bound to itch. Itch is also known as Pruritus. Itching is a built-in mechanism of our body which alerts us about a potential threat that is bothering us or being harmful to us.

 At times, itching could be nothing much severe, but this won't be the case most of the times. Some type of external stimuli which could include a bug, dust, a clothing fiber or even a hair can trigger itching. Moreover an allergy to certain thing or food or smell can trigger itching. So when external objects such as dust, mosquito or bug land on our skin, they bother it somehow and result into itching. It does not have to start immediately, but the rubbing or an allergy could trigger out itching.

And then there is food allergies which can trigger itching and redness of your skin. A person who is allergic to a particular food, or dust particles can experience severe itching. Once the dust layer scratches your skin area the receptors of the skin will become irritated. These receptors send signal through fibers into the skin to your spinal cord and then to your brain - the result you start itching.

Why do we scratch a itch is really a wonder. Scratching the itch makes us feel better, and that is our first response to the itch. Once we scratch the itch with our finger nails we feel much better and get some relief. Very often scratching helps relieving itch by removing the irritant as soon as possible. When the itching is triggered due to an allergy, we need certain medications to help us solve the problem.
