In addition to behavioral changes and good sleep habits, there are some non-medical options for improving symptoms of Shift Work Disorder. One of these options may help regulate your sleep or improve your alertness on the job.


Melatonin is a drowsy-making chemical naturally produced by the body. In people not working night shifts, melatonin levels increase a few hours before bedtime when the body is preparing for sleep. Melatonin levels remain high at night, decrease in the morning, and remain very low during the rest of the day. If you work on a shift schedule and you’re exposed to light during the evening or night, your body’s natural production of melatonin can become suppressed. In addition, light at night can cause a change in the timing of this melatonin profile (which is normally high at night and low during the day). In most shift workers, the melatonin profile does not realign properly with night work and sleep during the daytime. This lack of proper alignment of the melatonin profile—and the rest of the circadian system—contributes to disturbed daytime sleep, decreased alertness during night shifts, and presumably to many other health problems associated with shift work.

Taking melatonin may help to “reset” your internal clock if you need to adjust to an irregular schedule. Melatonin is sold as a dietary supplement like vitamins and minerals and is not regulated by the Food and Drug Administration. If you’re considering taking melatonin, discuss it with your doctor and make sure you use it properly—in the correct dose and at the proper time. Inappropriate use of melatonin can backfire and increase sleep problems.

Light therapy

Light is a powerful signal for your internal clock. Light therapy may help shift workers adjust to irregular schedules. Light has two primary effects on your sleep/wake pattern. It has an alerting effect, and it also has the ability to gradually shift sleeping patterns earlier or later, depending on the timing of light exposure. During light therapy, you sit near a light box for a prescribed amount of time. The time of day is very important to achieve
