Parkes (nd:4) discovered that disturbed sleep is an outcome of the disruption to normal circadian rhythms and her studies concluded that problems were caused by a mismatch between the need to be awake during night hours and sleeping during the day. Likewise, Finn (1981:32) states that the disturbance of these circadian rhythms contributes to physical and emotional problems. Parkes’ (nd:4) and Finn’s (1981:32) research revealed that shift worker’s sleep is often disturbed by domestic and traffic noise and unavoidable light and heat, which occur during the day.
Parkes (nd:5) states that gastrointestinal complaints, such as indigestion, heartburn, constipation, loss of appetite and nausea, are frequent among shift workers and are more common among night shift workers than those working during the day. What is more, Saskatchewan Labor’s (1998:5) research showed similar findings and they suggested reasons for this, such as over- or under-eating, relying on high-fat snack foods and drinking more coffee to stay alert at night, increasing the risk of developing ulcers. Finn’s (1981:32) research also revealed that loss of appetite and irregular eating habits are a common occurrence among shift workers which could lead to weight loss and nutritional deficiency. However, Finn (1981:32) also discovered that there was conflicting evidence regarding matter.
