Harvard Business Review: Just How Bad Is Business Travel for Your Health? Here’s the Data, key quote:
those who spent 14 or more nights away from home per month had significantly higher body mass index scores and were significantly more likely to report the following: poor self-rated health; clinical symptoms of anxiety, depression and alcohol dependence; no physical activity or exercise; smoking; and trouble sleeping.
I think it's obviously true and even worse especially for salespeople that need to travel from city to city vs just going to a single place and staying there for a week.
What do you think?
