There are many causes of itchy skin, starting with an allergic reaction. When we come into contact with substances that cause an allergic reaction to us, such as pollen, animal hair, dust mites, etc., our immune system releases excessive amounts of chemicals such as histamine, which leads to an allergic skin reaction and an itchy sensation.
Secondly, itching is caused by dryness. After prolonged exposure to dryness during cold, dry winters or in air-conditioned rooms, the skin tends to lose moisture and become dry. This is when the skin cracks and flakes, leading to an itchy sensation.
Infection is also a cause of itchy skin. When our skin is infected by bacteria, fungi or parasites, these microorganisms release toxins that irritate the skin leading to an itchy sensation.
Besides these common causes, there are other factors that may lead to itchy skin, such as medication side effects, neurological disorders, and endocrine disorders. All of these factors may cause itchy skin and need to be treated and regulated according to the specific situation.
The treatments for itchy skin can be taken according to different causes. If the itchy skin is caused by allergies, you can avoid contact with allergens and use anti-allergy drugs or topical anti-allergy creams to relieve the itchiness. If dryness is the cause of itchy skin, you can keep the humidity in the room moderate, and use moisturizing cream or lotion to replenish moisture. If the itchy skin is caused by an infection, you need to go to the hospital and get treatment as recommended by your doctor.
Itchy skin is a common symptom that can be caused by a variety of reasons, including allergies, dryness, and infections. Treatment needs to be tailored to the specific cause. Maintaining good living habits, paying attention to personal hygiene and eating a balanced diet are also helpful for skin health. If the itchy skin is severe or cannot be relieved for a long time, it is recommended to consult a medical professional for advice.
