Haven’t had a vacation
in a year, or more? It could be bad for your mental and physical health. The Quartz
journal selected several studies that show that it’s time to take a break
(Quartz, September 5, 2015).
A 1991 longitudinal study
that commenced in 1948, called the Farmingham study, showed that non-working women
who took vacation only once every six years or longer had nearly twice the risk
of developing a fatal heart disease and heart attacks than women who took
vacations at least twice a year. A 2012 study published in the American Journal of Epidemiology
assessed 50 years of research and found that a 10-hour or more workday
increased the risk of coronary heart risk by 80% for both men and women.
In a 2012 study by the
Centre of Expertise for Work Organizations at the Institute of Occupational
Health in Finland, using the Whitehall II database of British public servants, mental
health issues were examined. Researchers found that people who worked more than
11 hours a day were more than twice as likely to have a major depressive
episode than people who worked 7-8 hours a day. This was likely even in people
who had no prior mental health issues. The Swedish Uppsala University conducted
a study in 2013 on the impact of vacations on mental health. They used data on
the sale of anti-depressants. They found a small but ‘practically significant’
relationship between more people taking vacations and fewer anti-depressant
drugs sold.
A 2012 University of
California study gave two groups of participants the same problem. One group
was given a short break during the task, while the other group was required to
work until the task was completed. Researchers found that participants that had
a short break showed an increase in creative solutions to the problem.
The Institute of
Occupational Health in Finland showed in 2008 that people who worked a 55-hour
work week had lower cognitive function, including poor vocabulary and
reasoning, than people who worked a 40-hour work week.
It was also found that
the short-term benefits of vacations disappear quickly – as quickly as a week or
less after the holiday, people’s stress levels rose. Research from the
University of Tampere in Finland confirmed the short-term effects of holidays,
but added that the collective or cumulative effect of holidays over time was
vital to good health.
