Itchy skin, also known as pruritus, can appear suddenly and become very uncomfortable. This condition can affect anyone, and it sometimes gets worse at night. Understanding the causes and how to relieve it quickly can make a big difference.

Main Causes of Sudden Itching

  • Dry skin: When your skin loses moisture, it becomes flaky and itchy.
  • Insect bites: Mosquitoes, bedbugs, or lice can trigger intense itching.
  • Allergic reactions: Some soaps, fabrics, or foods may cause itching.
  • Skin infections: Conditions like eczema, ringworm, or dermatitis may be responsible.
  • Internal diseases: Liver problems, diabetes, or kidney issues can also lead to generalized itching.
  • Medications: Certain drugs may have itching as a side effect.
  • Mental health: Stress, anxiety, or depression can sometimes cause skin discomfort.

Why Itching Gets Worse at Night

At night, your body temperature rises and blood flow increases, making itching more noticeable. Hormonal changes and lower production of anti-inflammatory substances also contribute to nighttime itching.

How to Stop Itching Quickly at Home

  • Moisturize daily: Use fragrance-free creams or lotions after bathing.
  • Use cold compresses: Apply cold water or ice packs to reduce itchiness.
  • Oatmeal baths: Soak in a tub with oatmeal powder to calm irritated skin.
  • Avoid scratching: Wear gloves at night and keep nails short.
  • Apply apple cider vinegar: Use diluted vinegar on the itchy area for relief.
  • Take antihistamines: Over-the-counter medicines can help control allergic itching.
  • Wear soft clothing: Avoid wool or tight clothes that irritate the skin.

When to See a Doctor

If the itching lasts more than a week, spreads all over the body, or is accompanied by other symptoms like weight loss, night sweats, or rashes, you should consult a doctor for further evaluation.
