Beware the dangers of (especially midnight hour) shift work
Research published in Occupational & Environmental Medicine in November, 2014, which examined the chronic effects of shift work on cognition, showed that shift work is associated with impaired cognitive function.[1]
This association was strongest for those who had been employed in shift work for more than ten years and was equivalent to an additional 6.5 years of age-related decline. The United Kingdom’s Health and Safety Executive (HSE) states in the past 25 years, there has been a gradual increase in the number of people who undertake shift work in the UK, with around 5-20 per cent of the working population now engaged in shift work that involves night work. This equates to 3-6 million workers.
