Recreational winter exercise can reduce allergic airway inflammation, including fractional oral exhaled nitric oxide (FeNO) and nasal eosinophil counts. This outdoor activity also sustainably improves allergic symptoms without adverse effects.
Area of Science:
- Allergy and Immunology
- Environmental Medicine
- Exercise Physiology
Background:
- Physical exercise is recommended for allergic rhinitis and asthma.
- Limited data exists on winter outdoor exercise's impact on allergic airway inflammation.
Purpose of the Study:
- To investigate the effects of recreational winter exercise on allergic airway inflammation.
- To assess impacts on quality of life, spirometry, and cardiorespiratory fitness.
Main Methods:
- Longitudinal, randomized controlled intervention study.
- Ten-day winter sports program for the exercise group.
- Control group received no intervention.
Main Results:
- Significant reduction in fractional oral exhaled nitric oxide (FeNO) in the exercise group.
- Short-term decrease in nasal eosinophil count observed.
- Sustainable improvement in allergic symptoms reported.
Conclusions:
- Recreational winter exercise in moderately cold temperatures reduces allergic airway inflammation.
- Outdoor winter activity improves allergic symptoms and FeNO levels.
- No adverse effects were noted, suggesting safety.
