How Colorado’s Altitude Affects Allergies and Asthma


Colorado’s breathtaking mountain views and outdoor lifestyle come with a unique challenge—high altitude. For those with allergies and asthma, the state’s elevation can have a noticeable impact on symptoms. Understanding how Colorado’s altitude affects allergies and asthma can help residents and visitors breathe easier.

How Does Altitude Impact Allergies and Asthma?

The combination of dry air, lower oxygen levels, and fluctuating weather patterns can affect respiratory health in various ways.

1. Drier Air Can Worsen Symptoms

  • Colorado’s high altitude means significantly lower humidity.
  • Dry air can irritate airways, leading to increased asthma symptoms.
  • Dehydration can cause nasal passages to become dry, worsening allergy symptoms.

2. Pollen Counts Vary by Elevation

  • Higher elevations typically have lower pollen counts than lower-altitude regions.
  • Trees, grasses, and weeds release pollen at different times of the year, affecting seasonal allergies.
  • Wind can carry pollen across large distances, impacting those sensitive to airborne allergens.

3. Air Pressure and Oxygen Levels Play a Role

  • Lower oxygen levels at high altitude can make breathing more difficult for people with asthma.
  • Changes in air pressure can trigger sinus congestion and headaches.
  • Exercise at altitude can increase respiratory strain for those with asthma or chronic allergies.

Managing Allergies and Asthma in Colorado’s Altitude

Stay Hydrated

  • Drink plenty of water to keep airways moist and reduce irritation.
  • Use a humidifier indoors to combat dry air, especially in winter months.

Monitor Pollen Levels

  • Check daily pollen forecasts before spending time outdoors.
  • Keep windows closed during peak pollen seasons to reduce exposure.
  • Shower and change clothes after being outside to remove pollen particles.

Adjust Medications as Needed

  • Talk to a doctor about adjusting allergy or asthma medications when visiting or moving to high-altitude areas.
  • Carry a rescue inhaler if asthma symptoms worsen with altitude changes.
  • Consider allergy shots or other long-term treatments for persistent symptoms.
