Solutions for Itchy Skin: Understanding Causes and Remedies to Restore Healthy Skin

News

by Reichpharm

Hong Kong's weather is unpredictable, with frequent fluctuations in temperature and humidity. These changes can lead to dry skin, redness, itching, and sensitivity. It can trigger seasonal eczema in severe cases, especially in patients with weaker skin barriers, such as the elderly and infants. Itching can become unbearable at night, causing the skin to peel, bleed, and even fail to respond to eczema creams.

 

What Causes Itchy Skin?


 
Skin itching occurs when the skin encounters foreign substances, triggering an excessive immune response. It can be a symptom or a condition, and the possible underlying diseases include:

  1. Atopic Dermatitis: Caused by genetic defects leading to skin barrier dysfunction, resulting in sensitivity to external allergens, dryness, itching, and flaking.
  2. Urticaria: Triggered by allergens such as stale seafood, dust mites, pollen, or dust.
  3. Contact Dermatitis: Caused by exposure to chemicals or cosmetics.
  4. Dyshidrosis: The cause is unclear, but triggers include metals like nickel, cobalt, and chromium, as well as factors like lack of sleep, smoking, and cleaning products.
  5. Eczema: Itching or skin inflammation generally falls under the category of eczema, which has triggers that include food, climate, pollution, and even emotions.
  6. Photodermatitis: Caused by sun exposure, leading to skin itching.
  7. Drug Allergies: Skin reactions due to medication allergies.

Other factors that may aggravate or trigger skin allergies include certain foods (e.g., mangoes, stale seafood, kiwifruit, bamboo shoots), temperature changes, and humidity. Any contact with external substances can cause skin itching.

Why Does Scratching Make Itchy Skin Worse?


The main reason scratching intensifies itching is the “Itch-Scratch Cycle.”

Why Does Scratching Make Itchy Skin Worse?

When eczema flares up, the itching sensation is irresistible, prompting scratching. However, the skin is already very fragile at this stage, and nails can easily break the skin, introducing bacteria from the fingers and causing infections. Infected wounds worsen eczema symptoms, causing skin pain and further inflammation, exacerbating the itching. This creates a vicious cycle.
During acute eczema flare-ups, it’s crucial to stop scratching. If the itching is unbearable, consider using quick-relief methods.


Quick Relief for Itchy Skin


If you prefer not to use medication for itching, you can try cold compresses and wet wraps to reduce the discomfort of acute eczema and alleviate the stinging sensation.

Cold Compress for Itch Relief


If eczema causes skin pain and itching, use ice cubes or wet a towel, place it in the refrigerator for 5-10 minutes, and then apply it to the affected area. Cold compresses constrict blood vessels, reducing itching and soothing inflammation.

Why Is Itchy Skin Worse at Night?


The human body secretes anti-inflammatory hormones like corticosteroids and adrenal cortical hormones in the morning. At night, the secretion or concentration decreases, exacerbating issues like urticaria. Additionally, during the day, activities distract you from the itching, while at night, the senses are more sensitive, and allergens from bedding, clothing, or food can increase, making the itching more intense.
