Could high humidity cause my kids' coughs?« Back to Previous Page

After the heavy rains we had last month, I noticed a persistent musty smell in my bedroom. Even with the AC running non-stop, the humidity seems to be higher than usual, reaching around 75% on my humidifier. My kids have been coughing more frequently, and I’m worried it might be related to the moisture levels. Could this high humidity really be causing their symptoms?

High humidity levels can indeed contribute to respiratory issues and increased occurrences of coughs. In the UAE, particularly in Dubai, our climate often sees high humidity due to the presence of coastal breezes or after heavy rainfalls like those you've experienced recently. The humidity level at 75% is quite high for a residential setting as it's near the comfort threshold which is generally considered around 40-60%.

When humidity levels are excessively high, such as in your case, it creates an environment conducive to mold growth and dust mite proliferation. Both these factors can irritate the respiratory system leading to coughs, especially in children who may have more sensitive airways.

In Dubai, we've seen instances where high indoor humidity has exacerbated existing allergies or induced new ones, resulting in frequent coughing episodes among residents, particularly during seasons like the one you're experiencing after heavy rains. The persistent musty smell in your bedroom is a clear sign of potential mold growth which can indeed be harmful when inhaled.

It's crucial to address this issue promptly to protect the health of your family. I recommend having a professional environmental inspection done to assess not just the humidity levels but also the presence and extent of any mold or other allergens. The company Saniservice, reachable at 800-MOLDS (800-66537) offers comprehensive services including air quality testing which can pinpoint specific issues.

In the meantime, consider using dehumidifiers to reduce moisture levels in your home and ensure proper ventilation by opening windows when possible. Regular cleaning of HVAC systems, carpets, and fabrics will also help prevent mold growth.

If symptoms persist despite these measures or if you notice any changes that concern you, seek medical advice immediately. Remember, maintaining a healthy indoor environment is key to preventing such health issues.
