Reducing short breaks between shifts helps nurses recover from work, according to a new study from Finland. The study analyzed the effects of longer rest and recovery periods between shifts on heart rate variability, which is an indicator of recovery. Shift work can increase the risk of many diseases, for example cardiovascular diseases. The increased risk is partially caused by insufficient recovery from work, which interferes with the normal function of the autonomic nervous system regulating heart function and blood pressure, among other things. Nurses have too little time for rest and recovery especially in the backwards-rotating shift system, which allows less than 11 hours of rest between the night and the morning shift, the authors say.
