High stress and a lack of physical activity are causing employees in the healthcare sector to lose nearly 27 days a year in lost productivity on average.
The study, which was conducted by VitalityHealth, Mercer, the University of Cambridge and RAND Europe, found that productivity varies enormously between industries compared to a national average of 23.5 days
The financial services industry loses the second most time: 24.9 days per employee a year, while high-tech loses the least- just 18.9 days per employee per year respectively.
Britain's Healthiest Workplace (BHW) surveyed more than 32,538 workers across all UK industries, revealed that high stress and lack of physical activity are causing workers in the healthcare sector to lose.
The UK loses £57bn a year on average in in lost productivity. Work-related stress plays a significant role in the productivity losses incurred, with 73% of employees nationally suffering from at least one dimension of work-related stress.
Those industries with higher productivity losses typically have higher levels of work-related stress.
Physical activity levels in financial services are in line with the national average, but in healthcare fall below the average of 64.4%, with just 62.2% of workers falling into the healthy range.
Transportation, shipping and logistics - the worst industry for stress and lack of physical activity and the third least productive industry - also highlight the correlation between these two factors and productivity output.
The high-tech industry scores highest in the productivity stakes, losing just 19 days per employee per year. High-tech employees are the most physically active, with 71.5% of employees in the healthy range, and are also the least stressed.
Shaun Subel, strategy director at VitalityHealth said: "Although alcohol consumption, poor diet and smoking have a significant impact on long-term health, it is clear to see that day-to-day productivity loss centres on physical activity and stress levels.
"Within the significant industry fluctuations, it is quite worrying to see that even in high-tech, the best-performing sector in terms of productivity, 19 days of productive time is still lost by each employee each year.
"Encouragingly we note that on an individual company basis, where there is an increased investment in health promotion, the proportion of employees in good or excellent health grows, while the costs to productivity associated with absenteeism and presenteeism reduce.
"We would urge all companies, and especially those in sectors suffering from acute productivity loss, to invest in the health and wellbeing of their staff. Reducing workplace stress and encouraging employees to stay physically active should help increase productivity levels and protect the business bottom line."
Chris Bailey, partner at Mercer, added: "Modern working practices and the make-up of roles within the UK's workforce has impacted on the health of individuals significantly. Technology has allowed a more sedentary working life to become the norm whilst the rise of the UK's service economy has reduced the number of manual workers and physical activity.
"But individual employers can, and do, act to buck these trends and create competitive advantage within their peer group by doing so.
"It's no surprise that new tech firms without legacy working practices have lower levels of stress, and lower lost productivity, whilst more established industries sometimes struggle to implement change and create a healthy working environment."
