(NEW YORK) — Researchers say that workers who take popular sleep medications after working a night shift may not be receiving the benefits they hope for.
According to a Cochrane Review analysis of 4,651 past studies, melatonin only increased the average length of sleep time after a night shift by approximately 24 minutes. Additionally, the extra sleep workers gained was often low-quality sleep.
Other drugs, meant to help improve a worker’s level of alertness when they are awake, including armodafinil and modafinil, were discovered to be slightly more effective than a placebo in decreasing sleepiness. However, researchers say, the effects of those drugs did not last an entire shift — and side effects for use of both drugs get worse with higher doses.
