![]() Indeed, it was demonstrated that wind from the north was typically of low humidity and low temperature both of these conditions were related to asthma exacerbations. The population of Bermuda considered a north wind to be bad for asthma, from experience. ![]() 8 used Bermuda, an isolated, clean island without air pollution or aeroallergens. The key to performance of effective studies of the outdoor environment may be to select an appropriate location that provides a relatively homogenous outdoor environment for the population. ![]() Thus, well-designed studies and appropriate analytical methods are necessary to account for the multiple confounding factors. 5, 7 This might suggest that the effects of the outdoor environment on asthma are complex and not dependent simply on the amount of exposure but related to complex interactions among environmental factors and personal components. 4, 5, 6 However, studies exploring relationships among weather conditions, air pollution, and asthma have reported inconclusive and inconsistent results. 1, 2, 3 Weather conditions also influence the levels of air pollutants, some of which have been suggested as asthma triggers. There are strong seasonal trends in asthma-related hospital admissions and cold dry air can trigger asthma symptoms.
