Post-Storm Allergens: How to Mitigate Them

Written by The Allergy & ENT Associates Team

Houston residents are no strangers to powerful storms that bring heavy rain, strong winds and flooding. While these storms can cause visible damage, they also create ideal conditions for allergens that can linger long after the skies clear. Post-storm allergens can trigger allergy and asthma symptoms, making it crucial to take proactive steps to reduce exposure. At Allergy & ENT Associates, we understand the importance of managing these allergens to keep you and your family healthy and comfortable.

Here are some of the most common allergens that emerge after a storm — and what you can do to mitigate them.

Mold: The Biggest Post-Storm Threat

One of the most prevalent post-storm allergens is mold, which thrives in damp, water-damaged environments. After a storm, standing water, leaks and high humidity levels create the perfect breeding ground for mold spores, which can become airborne and trigger allergy symptoms like sneezing, congestion and itchy eyes.

How to Reduce Mold Exposure:

  • Dry out your home as quickly as possible by using dehumidifiers, fans and open windows (if outdoor conditions permit).
  • Remove and replace water-damaged materials such as carpets, insulation and drywall.
  • Use a HEPA air purifier to help capture mold spores in the air.
  • If you see visible mold growth, consider hiring a professional for safe removal.

Pollen: Storms Can Stir It Up

While storms often wash pollen out of the air, strong winds and fluctuating weather conditions can stir it back up, making post-storm days challenging for allergy sufferers. Rain can also cause plant growth spurts, leading to a rise in pollen levels shortly after a storm.

How to Reduce Pollen Exposure:

  • Keep windows and doors closed to prevent pollen from entering your home.
  • After spending time outside, change clothes and take a shower to remove pollen from your skin and hair.
  • Use high-efficiency air filters in your HVAC system and replace them regularly.

Dust Mites: Thriving in Humidity

After a storm, humidity levels in Houston often skyrocket, creating the perfect environment for dust mites. These microscopic allergens can worsen allergy and asthma symptoms, particularly for those sensitive to indoor allergens.

How to Reduce Dust Mite Exposure:

  • Maintain indoor humidity levels below 50% using air conditioning and dehumidifiers.
  • Wash bedding, curtains and stuffed animals in hot water weekly to kill dust mites.
  • Use allergen-proof covers on pillows and mattresses to reduce exposure.
