We have just published a review of the public evidence on workplace sleep and stress in Britain. Every figure comes from a named source. Here is what stood out.
16.4m
working days lost in a year to work-related stress, depression or anxiety in Great Britain.
HSE, 2023/24
In 2023/24 the Health and Safety Executive recorded 776,000 workers in Great Britain suffering from work-related stress, depression or anxiety. Together these accounted for 46% of all work-related ill health and an estimated 16.4 million lost working days, more than half of all days lost to ill health that year.
RAND Europe estimated that insufficient sleep costs the UK economy up to £40 billion a year, equivalent to around 1.86% of GDP, with roughly 200,000 working days lost annually through a mix of absenteeism and reduced performance at work.
Deloitte estimated the cost of poor mental health to UK employers at around £51 billion a year. In the same research, 63% of employees reported at least one characteristic of burnout, up from 51% in 2021, while employers saw an average return of £4.70 for every £1 invested in mental health and wellbeing support.
