Especially if you’re constantly scratching, you become more susceptible to everything from small microtears that damage the skin barrier to open wounds that put you at high risk for infection and permanent damage. What causes your skin to itch? Itching, known medically as pruritus, can be triggered by a variety of environmental factors and lifestyle choices. In these cases, minor adjustments to your skin care regimen and habits are best. However, persistent itching can also be caused by more severe physiological and even psychological disorders - in which case you should seek out the advice of your dermatologist or doctor.Let’s jump into discussing some common culprits behind that nagging itch.

Common Causes of Itchy Skin
Dry skin
is one of the most common causes of skin itching. When your skin's moisture levels drop, it's like stripping away its natural shield, leaving it exposed to all sorts of environmental triggers that can set off an itching frenzy. This can result in feelings of tightness, discomfort, and irritation, prompting you to scratch and further exacerbating the problem.1 Therefore, ensuring proper hydration is crucial not only for relieving itching but also for maintaining overall skin health and resilience.
Skin irritants and allergens can also provoke an itch sensation. Whether it's pollen or perhaps an unknown shellfish allergy, histamines (your body’s reaction to allergens) can trigger a chaotic response from your immune system. These reactions occur when the immune system perceives harmless substances as threats, triggering a cascade of symptoms that include itching, redness, and swelling.2 Identifying and avoiding allergens is key to managing allergic itching and promoting skin comfort. Similarly, irritants encompass a range of substances capable of triggering itching upon contact. This includes harsh chemicals, fragrances, and certain fabrics that can irritate the skin. Prolonged exposure to these irritants can exacerbate the problem and worsen skin irritation. It’s important to note that what irritates or causes an allergic reaction is different for everyone, so pay attention to what irritates your skin.
Dermatitis is a group of inflammatory skin conditions, including contact dermatitis, atopic dermatitis, eczema, and psoriasis, that cause redness, itching, and the formation of rashes.3 It can be triggered by allergens, irritants, genetics, or environmental factors. Managing dermatitis often involves heavy moisturization and finding and avoiding triggers. These conditions require proper diagnosis and treatment by a healthcare professional.

When to See a Doctor for Itching Skin
If itching persists for more than a few days despite home remedies, consult a doctor. Similarly, itching that interferes with daily activities, such as sleeping, working, or socializing, should not be ignored. Persistent itching may be a sign of an underlying medical condition that requires evaluation and treatment. Additionally, any noticeable changes in the skin, such as redness, swelling, rash, or sores, along with itching, should be evaluated by a healthcare professional. These changes may also indicate an underlying skin condition that requires medical attention.
