People with asthma should consider limiting the use of melatonin as a sleep aid, according to researchers at National Jewish Medical and Research Center. Pulmonologist Rand Sutherland, M.D., M.P.H., and his colleagues report in the September 2003 issue of the Journal of Allergy and Clinical Immunology that higher levels of melatonin were associated with an overnight loss of lung function in asthma patients. Previous studies by the same group have shown that melatonin induces the release of chemicals that promote inflammation, a hallmark symptom of asthma.
