Extreme heat, precipitation linked to more severe asthma requiring hospitalization

Extreme heat and heavy rainfall are related to increased risk of hospitalization for asthma in Maryland, according to a study. Based on over a decade of asthma hospitalization data (115,923 cases from 2000-2012), Researchers observed a 23 percent increase in risk of asthma hospitalizations when there was an extreme heat event during summer months. This risk was higher among 5-17 year olds.
