Yes, high humidity can indeed cause musty odors. The presence of moisture creates an environment conducive for mold and mildew growth which are the primary culprits behind such unpleasant smells. In dubai, a place known for its warm and humid climate especially during certain months, maintaining indoor air quality is crucial.

In your case, the heavy rains last month have likely introduced excess moisture into your home, leading to condensation on windows and other surfaces. This high humidity combined with poor ventilation can certainly contribute to musty smells, particularly noticeable when the AC runs, as it circulates air that might be laden with moisture or microorganisms.

To address this issue, start by ensuring proper ventilation. Open windows during cooler parts of the day for natural airflow, if feasible and safe. Consider installing a dehumidifier which can significantly reduce indoor humidity levels. In more serious cases where you notice visible mold growth or persistent musty odors, it is advisable to seek professional inspection from certified companies in Dubai such as Saniservice.

Additionally, maintaining cleanliness is key. Regularly clean and dry surfaces that are prone to moisture accumulation like bathroom walls, kitchen areas, and around the AC units. Use a mixture of water and vinegar for natural disinfection which can help inhibit mold growth.

Bear in mind that in the UAE, particularly Dubai, there are no specific regulations mandating indoor humidity levels but maintaining a relative humidity between 30-60% is generally recommended to minimize health risks associated with high moisture environments. However, if you find yourself struggling to manage humidity levels or if the musty smell persists despite your efforts, it might be time to call in professionals who can provide more advanced solutions like air purification systems tailored for high-humidity environments.

Remember, prevention is always better than cure. By taking proactive steps now, you can prevent musty smells from becoming a recurring issue in your home. For any concerns or immediate assistance, don't hesitate to reach out to experts like Saniservice at 800-MOLDS (800-66537) or through their email hello@saniservice.com.

Hope these tips help in addressing the musty smell problem in your bedroom!
