## Q&A

**Q: What are the most common causes of itchy skin (gatal kulit) in Malaysia?**  
A: Tropical heat and high humidity increase perspiration, leading to blocked sweat glands (heat rash), allergen flare-ups (hives), contact dermatitis, and fungal growth. Environmental factors can also compromise the skin's natural moisture barrier.

**Q: What over-the-counter (OTC) medications can help relieve itchy skin?**  
A: Second-generation oral antihistamines (such as Cetirizine or Loratadine) help reduce allergic itching without causing heavy drowsiness. Topical calamine lotion cools heat-induced prickling, while 1% hydrocortisone cream reduces localized inflammation.

**Q: How does heat rash differ from allergic hives?**  
A: Heat rash (*miliaria*) presents as clusters of tiny, stinging red bumps in sweat-prone areas. Hives (*urticaria*) manifest as smooth, raised, swollen welts that change shape and appear suddenly across various body regions due to histamine release.

**Q: When is it necessary to see a doctor for skin itching?**  
A: Consult a physician immediately if itching persists for more than two weeks, spreads rapidly, impairs sleep, or is accompanied by fever, pain, yellow pus, or signs of bacterial infection.

**Q: How can individuals prevent recurring tropical skin irritation?**  
A: Wear breathable, loose cotton clothing, shower and dry off immediately after heavy sweating, use gentle pH-balanced body washes, and apply lightweight moisturizers to sustain the epidermal barrier.
