Vitamin D, which is primarily absorbed from the sun, plays a role in protection against childhood asthma. Now, a new study led by Valencian researchers has shown that children who live in colder, wetter cities are at greater risk of suffering from this respiratory problem, since there are fewer hours of sunlight in such places. “Prolonged exposure to the sun can cause cancer, but it’s also dangerous to avoid it. There has to be a balance between the pros and cons”, Alberto Arnedo-Pena, an epidemiologist at the Public Health Centre in Castellón and lead author of the research, which is part of the International Study of Asthma and Allergies in Childhood (ISAAC), led by Luis García Marcos of the University of Murcia, tells SINC.
