Study: Teenagers who stay up late are more likely to suffer from asthma, allergies

Teenagers who prefer to stay up late and wake later in the morning are more likely to suffer from asthma and allergies compared to those who sleep and wake earlier, according to a study published in ERJ Open Research.

Asthma symptoms are known to be strongly linked to the body's internal clock, but this is the first study to look at how individual sleep preferences influence asthma risk in teenagers.

Researchers say the study reinforces the importance of sleep timing for teenagers and opens up a new channel of research into how sleep affects teenagers' respiratory health.

The study was led by Dr. Subhabrata Moitra from the division of pulmonary medicine at the University of Alberta, Canada, who carried out the research while at the Barcelona Institute for Global Health, Spain.
