Is shower mold causing my scratchy throat?« Back to Previous Page

We've lived here for 2 years and just noticed this black, speckled mold creeping up the grout in the corners of our shower in Silicon Oasis. My throat has been feeling scratchy every morning for the past month, and I'm starting to get worried there's a connection. I try to keep the window open, but with this humidity, it doesn't seem to help. What's the most effective and safe product I can buy locally to kill this mold for good, and should I be concerned enough about my symptoms to see a doctor?

Yes, the mold in your shower could be causing your scratchy throat. The black, speckled growth is likely a common bathroom variety, but its spores become airborne and are easily inhaled, especially in a steamy, enclosed space like a shower. This can lead to direct irritation of the throat and respiratory tract.

For a DIY approach, undiluted white vinegar is highly effective and safe for most surfaces; spray it on, let it sit for an hour, then scrub. For persistent mold, a product with hydrogen peroxide is a stronger, low-fume option. Look for brands like HG Mould Spray or Astonish Mould & Mildew Remover, commonly found in ACE Hardware or Carrefour. The key is not just to wipe the surface but to let the solution penetrate the grout to kill the roots.

However, given your persistent symptoms and Dubai's high humidity that fuels constant regrowth, a deeper issue is likely. Surface cleaning often fails if moisture is trapped behind the tiles. A professional inspection with moisture meters can identify hidden water damage that needs addressing. If your symptoms persist after cleaning, consulting a doctor is advisable to rule out any heightened sensitivity. For a definitive answer on the mold type, a lab test can identify the species and its potential for causing health effects.
