Teenagers who prefer to stay up late and wake later in the morning are more likely to suffer with asthma and allergies compared to those who sleep and wake earlier, according to a study published in ERJ Open Research.
The findings reinforce the importance of sleep timing for teenagers and opens up a new channel of research into how sleep affects teenagers’ respiratory health.
This is the first study to look at how individual sleep preferences influence asthma risk in teenagers. It involved 1,684 adolescents in West Bengal, India, aged 13 or 14 years, who were taking part in the Prevalence and Risk Factors of Asthma and Allergy-Related Diseases among Adolescents (PERFORMANCE) study.
Forty-two per cent and 9 per cent of participants were identified as morning and evening types, respectively, while the rest were intermediate types.
The researchers found that the chance of having asthma was around three times higher in teens who preferred to sleep later compared to those who preferred to sleep earlier. They also found the risk of suffering allergic rhinitis was twice as high in late-sleepers compared to early-sleepers.
