Opioids are not sleep aids, and can actually worsen sleep research finds

A systematic review found that opioids have a small improvement in sleep quality, but this is not consistent with results from sleep assessment technologies. Patients on opioid therapy are also at risk of excessive daytime sleepiness and increased risks of sleep apnea. The study calls for better research into the effects of painkillers...
