Monsoon Allergies in Mumbai & Thane: why you sneeze more in the rains

The ICMR estimates that 20–30% of Indians have an allergic condition, and cases peak during the monsoon. The reason is simple: moisture.

• Mould thrives on damp walls, ceilings, cupboards, carpets and even books, releasing spores into the air.
• Dust mites multiply in warm, humid bedding, pillows, curtains and sofas.
• Pollen and pollution particles linger longer in heavy, moist air.

• Frequent sneezing and a runny or blocked nose
• Itchy, watery or red eyes
• Cough, wheezing or breathlessness — especially with asthma
• Skin itching, rashes or worsening eczema

Colds usually settle in 5–7 days and may come with fever or body ache. Allergy symptoms drag on for weeks, flare in specific places (like a damp room), and typically come with itching. If your 'cold' returns every monsoon, it's worth getting tested.

• Keep indoor humidity around 30–50% — use a dehumidifier or AC where possible.
• Wash bedding weekly in hot water (60°C or higher) to kill dust mites.
• Fix damp patches and leaks; wipe down surfaces prone to mould.
• Use exhaust fans, and open windows only when it isn't raining.
• Dry clothes fully — avoid damp laundry indoors.

If symptoms return every monsoon, disturb your sleep, or your asthma is harder to control, a proper evaluation helps. Skin prick testing can pinpoint whether dust mites, mould or something else is the trigger — so treatment targets the real cause rather than masking symptoms.
