University of Victoria study shows stress impact on Greater Victoria nurses

Stress may be impacting sleep, heart health of local hospital nurses

Early data from a new University of Victoria study reveals that the region’s nurses are experiencing stress-related health impacts during the COVID-19 pandemic.

The results are early, says researcher and UVic grad student Marisa Harrington, but they show poorer sleep quality compared to the average person, as well as a reduction in heart rate variability.

Harrington, along with supervisor Lynneth Stuart-Hill, looked into the physiological impacts of stress on 10 Greater Victoria hospital nurses. Funded by UVic’s Centre for Occupational Research and Testing, participating nurses wore a watch-sized monitor over an eight-day shift rotation.

Their sleep patterns, heart rate and heart rate variability were all monitored. The stress responses were significant and similar, according to the study, regardless of the department or hospital the nurse worked in.

“We know that this is a population that feels stressed psychologically,” Harrington says. “Now, we’re establishing that there’s a measurable physiological impact as well.”

Early analysis of sleep data reveals that the nurses are getting less sleep than the average person. The data also shows that they are spending more time in light sleep and less time in REM sleep – a deep phase of sleep thought to increase brain activity.

“We’re still analyzing, but we are seeing significant data already around sleep in particular,” Harrington says. “We’ve looked at the cardiovascular data and there is definitely an effect there as well.”

Early data shows a reduction in the nurse’s heart rate variability, which indicates that the body’s sympathetic nervous system, responsible for ‘fight, flight or freeze’ responses, is chronically dominating the parasympathetic nervous system, which works to keep the body calm.

The study wasn’t created for the pandemic but will likely shed some light on the exacerbated stresses caused by the health crisis, Harrington said. “It’s a really underrepresented group in physiological research,” she said. “From talking to the nurses, even working before the pandemic these issues have come up and the pandemic has only exacerbated the stressors.”

The study will also analyze nurse’s saliva for cortisol, melatonin and interleukin-6, markers associated with stress, sleep and inflammation, respectively. Phase two of the study is now underway with a new group of participants.

Harrington anticipates the second phase will be complete in the spring.
