August’s online edition of Pediatric Allergy, Immunology, and Pulmonology includes an article examining how cold and warm seasons affect the occurrence of exercise-induced bronchoconstriction (EIB) in children. Researchers studied 213 non-asthmatic schoolchildren aged 15 – 17 years, collecting spirometry data in winter and summer for two years. They found that “the occurrence of EIB differed according to the season,” with rates of EIB higher in the winter months. They concluded that “seasonal variability affects the occurrence of EIB in healthy school children,” and “occurrence of EIB is associated with environmental temperatures and humidity.”
