Night workers

Working nights can affect health and causes other safety concerns.

Health problems occur because people are working outside normal 'circadian' rhythms. This disrupts sleep patterns which causes fatigue, that can have physical and psychological consequences. Nights workers are believed to be at higher risk of heart and stomach problems. Also, working unusual hours can impact relationships.

People working at night are likely to be tired and so prone to errors. Also, it is likely to be dark and there is usually less support (e.g. technical), which can create problems.

Where people work shifts (i.e. not on permanent nights) the pattern of days to nights and how they rotate can make a significant difference. Night workers can reduce risks by making sure they take their breaks (i.e. do not work overtime), get sleep when they can, power napping, eating healthily and not smoking.
