Insomnia is a significant risk factor for a wide range of physical and mental conditions, according to a recent study published in the Journal of Sleep Research. The study by Børge Sivertsen, Tea Lallukka, Paula Salo, Ståle Pallesen, Mari Hysing, Steinar Krokstad, and Simon Øverland found the odds ratio (OR) for depression in patients who had reported insomnia 11 years earlier was 2.38. Also linked were anxiety (OR: 2.08), fibromyalgia (OR: 2.05), rheumatoid arthritis (OR: 1.87), whiplash (OR: 1.71), arthrosis (OR: 1.68), osteoporosis (OR: 1.52), headache (OR: 1.50 , asthma (OR: 1.47), and myocardial infarction (OR: 1.46).
