From 2011 to 2022, a higher morning circadian preference was linked to better health related quality of life (HRQOL) in adults with asthma, according to a study published in The Journal of Allergy and Clinical Immunology Global. The researchers administered the reduced Morningness Eveningness Questionnaire (rMEQ) and the short-form Chronic Respiratory Questionnaire to 691 adults with asthma. Most participants were female (59%), with a mean age of 49 years. They found that participants with a higher rMEQ score indicating stronger morning orientation reported significantly less fatigue and better emotional function. Specifically, morning preference was associated with reduced fatigue (β=0.06) and improved emotional well-being (β=0.03). These relationships were partially explained by lower anxiety and depression, reduced alcohol use, and better sleep quality. The researchers concluded that working with patients with asthma to promote morning habits and schedules may be beneficial.
