If travel is a big part of your job, you’re at risk. You need to be aware of the risks and how to best mitigate them for yourself.
“A new study finds that people who travel for business two weeks or more a month report more symptoms of anxiety and depression and are more likely to smoke, be sedentary, and report trouble sleeping than those who travel one to six nights a month.”
I was aware of these risks when that was my job. I spent 5 years as a regular traveler, but that was mitigated by some of the other things I did, in terms of being social (which was my job), sleeping, taking time for myself, being selfish a bit with my time at home, etc. You can’t go in to that type of work blindly.
