As colder temperatures arrive, individuals with chronic bronchitis and COPD face heightened challenges from increased respiratory infection rates and the physiological effects of the season. The convergence of cold, dry air, seasonal viruses like influenza and COVID-19, and reduced activity levels can considerably exacerbate symptoms and trigger dangerous flare-ups. Understanding these risks – and proactive preventative measures – is crucial for maintaining respiratory health through the winter months, particularly as France continues to monitor ongoing circulation of respiratory illnesses [[1]].
Individuals with chronic bronchitis face increased challenges during the fall and winter months, as cold, damp conditions and the prevalence of viruses can worsen breathing difficulties and trigger flare-ups. Understanding these risks and taking proactive steps is crucial for managing the condition and maintaining respiratory health.
As colder weather arrives, people living with Chronic Obstructive Pulmonary Disease (COPD), often referred to as chronic bronchitis, need to be particularly vigilant. The autumn and winter seasons combine several factors that can exacerbate this respiratory illness: cold, dry air; seasonal viruses; increased time spent indoors; and reduced physical activity.
- Winter increases the risk of COPD flare-ups due to cold temperatures and infections.
- Prevention is key: vaccination, good hygiene, and protection from cold air.
- Regular physical activity and consistent treatment are important to prevent complications.
Cold, viruses, and inactivity: a challenging combination

Breathing cold air naturally constricts the airways. For individuals with COPD, who already experience narrowed and inflamed airways, this constriction is amplified. The result is immediate breathing difficulty, increased shortness of breath, and a feeling of tightness in the chest.
Adding to this is the increase in winter infections: the flu, the common cold, bronchiolitis, and COVID-19. For a compromised lung, even a mild virus can trigger an exacerbation—a sudden and sustained worsening of symptoms that can lead to hospitalization.
Winter also encourages people to stay indoors more often. The less ventilation, the more irritants like tobacco smoke or certain cleaning products accumulate, as do viruses that spread more easily within households. Finally, reduced physical activity exacerbates muscle loss and deconditioning, further worsening shortness of breath.
Essential steps for better winter living
The priority remains protecting against infection: annual flu vaccination, pneumococcal vaccination, updated COVID-19 boosters, and strict hygiene with handwashing, mask-wearing in enclosed spaces, and avoiding contact with sick people. This is particularly important as respiratory viruses continue to circulate.
When facing the cold, a few reflexes are essential: covering your nose and mouth with a scarf or mask to warm the air you breathe, prioritizing nasal breathing, avoiding strenuous exertion outdoors, and moving physical activities indoors. Ventilating your home daily, even briefly, also helps to renew the air without cooling the room.
Ongoing treatment should be continued without interruption, and pulmonary rehabilitation remains a valuable ally for improving breathing and maintaining muscle strength. Finally, if you experience unusual shortness of breath or fever, it is essential to seek medical attention promptly.
