Six years ago I moved to the island of O’ahu to escape Michigan's harsh winters. I decided to try working nights as a nocturnist hospitalist on a trial basis; I expected to return to days after one year. Surprisingly my new night schedule was not only workable, but I preferred it.
On the plus side are incentives such as fewer scheduled hours per month and more flexible vacation time in comparison to my daytime colleagues—for similar pay. The hospital where I work is a busy 500-bed Level II trauma center, but there is a certain solitude at night. You get to do more “pure medicine” and there is not as much emphasis on social work, case management and family conferences. I see the patient first on admission and the diagnostic problem solving is very rewarding.
Moreover, nocturnists attend fewer administrative and committee meetings. And we never have to wait for an elevator or parking spaces. My schedule consists of 12-hour shifts for three nights on, and then I have five days off to relax and recover. I like the lifestyle. My wife and I still breakfast together when I get home, before she heads off to work. Paradoxically, although we work opposite shifts, we now have more free time together, which we spend exploring Hawaii's beautiful beaches and mountain trails.
But nights are not for everyone. One downside is that the day hospitalists are the ones to have the satisfaction of seeing the very sick patients get better and leave the hospital. There is also an extended adjustment period as one's body adapts to changes in sleep and work patterns. I work with several dedicated nocturnists, and all of us handle sleep transitions in entirely different ways. Consequently we are extremely sensitive to changes in our work schedules. My program director put it this way: “You think day people schedules are tricky? Try tweaking the nights.”
I find that after a particularly busy series of shifts, sleep debt can take two days to pay off. Working more than three nights in a row triggers problems with transitioning back to days and can cause headaches and a lack of focus. Impediments to sleep include normal everyday activities that day-working people don't think about, like daylight and the din of lawn mowers, leaf blowers and barking dogs. Many of us night-workers rely on blackout curtains, white noise and occasionally sleep aids such as melatonin or a benzodiazepine. There is also a body of research about the health risks associated with night work, including depressed immune systems, injury, breast and prostate cancer, metabolic syndrome, impaired coronary circulation, diabetes and obesity, syncope and obstructive sleep apnea.
Managing the transition between day and night is a science and an art. It is worthwhile to review the literature on night and shift work and consider what works for you, and how your family and loved ones feel about it. Each individual has to create his or her own balance, which is an ongoing process. Ultimately it is the unique blend of professional, environmental and personal factors that will determine if nights are a good option for you, as they are for me.
