Asthma and allergies more common in 'night owl' teens: study

Teenagers who prefer to stay up late at night and sleep in late the next day are more likely to develop asthma and allergies than their 'early bird' counterparts, according to new research published today.'Compared to the morning type, those who go to bed late have approximately three times higher risk of developing asthma,' said principal investigator Subhabrata Moitra, a post-doctoral fellow in the Division of Pulmonary Medicine and a member of the Alberta Respiratory Centre at the University of Alberta.
