New international research from the Institution of Occupational Safety and Health claims that night shift work can lead to an increased risk of workers developing type 2 diabetes – especially for those who swap between day and night shifts regularly.
Other evidence suggests that shift work increases the risk of stroke or heart attack and even breast cancer for women.
The Institution of Occupational Health has recommended that increasing the regularity and amount of sleep can help boost the health and well being of shift workers.
Shift work should be in no longer than a 12-hour shift and if workers are changing from days to night regularly they should have at least two full nights of sleep in between changing the shift patterns.
Shift work can be managed so that the longer a worker can be in one pattern the more their body clock will adjust over time.
