One of the first things I noticed when I entered nursing was that it is a 24/7 kind of job. If there are patients in the hospital, someone has to stay with them around the clock. That means somebody has to be there all night watching them and providing care. Most people don’t stay up all night working—they go to bed and, hopefully, have a restful night’s sleep. Night nurses, however, do not. They are part of the 15-20% of workers who work non-traditional hours.
A recent study reported in Medscape Nurses looked at issues related to working nights. Interestingly enough, it is entitled, “Help Me Make it Through the Night”. Historically, nurses choose to work nights for a variety of reasons—preference, family responsibilities, increased pay, quieter and slower pace, more relaxed atmosphere, and fewer interruptions to name a few.
The night-working population has been the focus of several studies. One of the recurring findings is that working nights is associated with increased health risks. These include: increased risk of breast and colorectal cancer; increase risk for stroke; increase wrist and hip fractures; increase in type 2 diabetes; irregular menstrual cycles and reduced fertility; increased cardiovascular disease and mental health disorders; and, increased blood pressure. The studies are quick to point out that there is association—not causation.
Researchers believe that working nights results in a disruption in circadian rhythms. Circadian rhythm is synchronized through exposure to patterns of light and dark. The patterns control biological cycles that repeat roughly every 24 hours. When rest-activity cycles match the light-dark cycles, a person is said to be “in phase”. Circadian rhythm can be disturbed if a person is exposed to inadequate or irregular amounts of light at certain times of the day.
According to the study, night workers are deprived of restful sleep and the sleep loss builds over successive shifts. Their sleep is more fragmented and sleep times are shorter. This results in “sleep debt” and feelings of chronic fatigue that is not easily erased with “catch-up” sleep. Night-shift nurses report struggling to stay awake during shifts and may fall asleep for brief periods during the night or in the car on the way home from work.
Some nurses do prefer the night shift and work nights for much of their careers. These may be people who are “night people”. By natural inclination they prefer to sleep late, work best later in the day, and stay up late into the night. Their characteristic or chronotype is that of an “owl” as opposed to a “lark” (morning person) or “hummingbird” (what most of us are).
Some nurses are never able to adapt to working nights. But, there are ways to mitigate the effects of working the night shift.
• Stay awake at night and sleep during the day even on day’s off.
• Darken the room, use a sleep mask and ear plugs when sleeping.
• Disconnect the door bell and turn off the cell and other phones.
• Put sleep at the head of the “To-Do List”.
• Stay away from caffeine close to sleep time—drink warm milk instead.
• Follow a routine when getting ready for sleep.
• While working, spend as much time as possible in brightly lit rooms.
• Wear sunglasses when driving home in the morning.
• Don’t schedule appointments or activities during routine sleeping hours.
• Avoid eating large meals within 4 hours before sleeping.
• If working rotating shifts, rotate clockwise (days, evenings, nights).
• Seek exposure to light upon waking.
Some hospitals now allow nurses to take naps on their breaks during the night. Some research has demonstrated that taking a nap during the night may be counterproductive. It may impede the ability to have restful sleep once the shift is over. Others cite the occurrence of “sleep inertia” characterized by a momentary disorientation or grogginess that is experienced immediately upon awakening. However, others cite that taking a short, 20-minute nap can combat sleepiness and increase the ability to perform more effectively.
So, after all is said and done, nursing remains a 24/7 endeavor. And, since it is, it is imperative that research continue to provide the best data on which to base the most effective policies to ensure the best care for patients and their families.
