A study, recently published in ERJ Open Research, suggests that those teenagers who go to bed and wake up later are at higher risk to suffer from asthma and allergies than their peers who go to sleep and wake up earlier.
The research included 1,684 adolescents from West Bengal, India, 13 or 14 years old, who took part in the Prevalence and Risk Factors of Asthma and Allergy-Related Diseases among Adolescents (PERFORMANCE) study.
Study participants were asked about any wheezing, asthma, or symptoms of allergic rhinitis, such as a runny nose and sneezing. They also had to answer a series of questions to aimed to find whether they were ‘evening types’, ‘morning types’, or in between.
Lead study author Dr. Subhabrata Moitra from the division of pulmonary medicine at the University of Alberta, Canada, says: “Our results suggest there’s a link between preferred sleep time and asthma and allergies in teenagers. We can’t be certain that staying up late is causing asthma, but we know that the sleep hormone melatonin is often out of sync in late-sleepers and that could, in turn, be influencing teenagers’ allergic response.”
