Excessive noise levels in healthcare facilities that exceed hygienic standards have a significant negative impact not only on patients but also on the functioning of the nervous system and work performance of medical personnel. Recent scientific studies indicate that noise, as a stress factor, disrupts the activity of the central nervous system, reduces cognitive functions, and decreases work efficiency. The aim of this literature review is to systematically analyze the effects of noise in healthcare settings on the nervous system and occupational performance based on contemporary scientific evidence. Noise levels in intensive care units have frequently been reported to reach 70–85 dB. In addition, noise exposure has been associated with sleep disturbances, autonomic nervous system imbalance, and chronic fatigue syndrome.
