Expatriates or businesspeople who tend to travel regularly might want to consider taking out worldwide medical insurance to protect their health.
According to recent research by a team at Columbia University's Mailman School of Public Health, people who travel on business for two weeks or more a month tend to have poorer health than those who travel less often who remain in one place.
The research team found that obesity and poorer self-related health were affected, with regular travellers demonstrating a higher mean body mass index.
Furthermore, heavy travellers were found to be 260 per cent more likely to rate their health as fair to poor than those who travelled lightly.
Catherine Richards, doctoral candidate at the school's Department of Epidemiology and first author of the report, commented: "The results for self-rated health are of concern because this simple measure is a very robust predictor of mortality.
"Similarly, the associations between business travel and obesity are noteworthy because of the many negative health consequences of this condition."
