A recent study from the University of Eastern Finland has revealed an association between the season of birth and the incidence of asthma and allergic rhinitis. By analyzing data from 74,868 hospital patients, the study concluded that individuals born in autumn or winter exhibit higher rates of these respiratory conditions than those born in summer.

Seasonal Influences on the Development of Allergies

According to the researchers, the relationship between asthma, allergic rhinitis, and the season of birth may be connected to factors such as seasonal changes in sunlight, air quality, and vitamin D metabolism. During the colder months, there is less exposure to sunlight, which can affect vitamin D levels—a significant factor in immune development. Additionally, air during autumn and winter tends to be drier and more polluted, which can aggravate respiratory conditions.

Other Respiratory Diseases Were Not Affected

While the study found a strong association between the season of birth and asthma and allergic rhinitis, other respiratory conditions, such as chronic rhinosinusitis and respiratory disease exacerbated by nonsteroidal anti-inflammatory drugs (NSAIDs), did not show significant variations related to the time of birth. That suggests that specific factors of allergy and asthma are more susceptible to seasonal influences.

Future Implications for Public Health

These findings may help understand how environmental and seasonal factors impact the development of allergic diseases, offering new opportunities for the prevention and treatment of respiratory conditions. Awareness of the influence of the season of birth and preventive measures during the autumn and winter months can be good for the health of babies born during these times, especially in regions with severe climates like Finland.

The study illuminates the complex interaction between the environment and respiratory health, highlighting how even the timing of birth can have a lasting impact on people's well-being.
