Plan ahead. Take some time to research healthy restaurants in your destination. By making a list of a few you'd like to try when you get where you're going, you'll be less likely to just grab a meal at the first place you see. If a gym is important, book a hotel that is known for its fitness amenities. Many gyms and yoga studios also offer day passes for purchase.
Run for a cause. Whether your sport is marathon running, cycling or even doing an Iron Man, consider signing up for a race in place you've never traveled and make a holiday out of the event. You'll get a buzz training, knowing you'll be participating in a totally different venue and raising money for a new cause.
Digital detox. We keep talking about this, but these days our addictions to our electronic devices are actually leading to real health problems – from strained eye muscles to bad posture. So give your body a chance to recharge and make the decision to turn off your iPhone for at least 24 hours of your holiday.
Invite your dog along. More and more Americans are traveling with their dogs these days, as many hotels, not only in the U.S. but also globally, are promoting travel with pup by offering all sorts of packages for canine guests. Personally, I travel with my bully breed dogs as much as possible. I find doing so also keeps me in shape—I don't get the luxury of sleeping in or not going for a few decent walks per day when I'm looking after my dog. Plus dogs are good for stress relief, which will also keep you healthy on the road.
Drink lots of water. Staying hydrated is super important to maintaining wellness on the road. This is especially true when traveling internationally on long flights with changes in time zones.
Stick to your normal routine. If you usually go for a run or hit the gym in the morning, try to maintain this routine when you're on the road. The same goes for bedtime. Sure you can stay up late one night, but in general try to keep your shut-eye times similar to when you're at home to keep your body on schedule.
Try a new sport. If you're getting tired of your regular gym routine at home, why not focus on learning a new sport on your next vacation. Whether you sign up for a yoga retreat or learn to kick-box in Thailand, you'll have a new skill to take home with you, making the return to real life more stimulating—especially if you keep going once you're home.
Sweat and soak. When I'm jet-lagged and feeling toxic from a long flight, there is no better detox for me than some dedicated sauna and Jacuzzi time. A massage and facial can also help. Really, I try to book a spa day at the beginning of my trip rather than my end. This way I go into the holiday feeling relaxed and refreshed.
Live local. Connecting with new friends is another way to feed your mind on the road. Eat your way into the heart of a new culture with EatWith, which allows home cooks around the world to invite you in for dinner. Want a truly local guide? Vayable and even the new Airbnb Experiences pair travelers with locals who have similar interests.
Be mindful. Philippe Brown, founder of bespoke travel company Brown + Hudson, always builds in down time for his travelers. After touring that temple in Cambodia, don’t immediately rush to the next activity, he says. Find the best possible view of it and spend an hour sketching it—even if you’re not an artist. It gives your brain time to rest and absorb the experience.
