Study finds that working nights is associated with a 79% increased risk of cognitive impairment, potentially leading to memory loss in middle-aged and older adults.

  • Authors attribute disruption to circadian rhythm as the cause













A recent study suggests that working night shifts could potentially impair memory by up to 79% in middle-aged and older adults.

Existing research has already established the significant health effects of shift work, which refers to work schedules outside of the traditional 9am to 5pm working hours.

The study analyzed data on 47,811 adults, including employment information, work schedules, and results of cognitive function tests. One in five participants reported exposure to some form of shift work in their careers.

Those currently working night shifts had 79% higher rates of cognitive impairment compared to those working only day shifts. Additionally, those who had worked night shifts during their longest job had 53% higher rates of cognitive impairment.

The authors suggest that the disruption to the circadian rhythm, also known as our body clock, may be the cause for this impairment.
