There are a lot of people I've met who think that travel is a young person's game. It's something that you're supposed to do when you're 20 and figuring out yourself, but after that, you're supposed to stabilize and settle down. However, travel isn't just about having fun. Science proves that it's healthy for you in a variety of ways. 

Decades ago, public thought didn't grasp the link between diet and exercise making you healthy. Researchers are now saying the same things about travel adding to lifespan and capacity. As these benefits become more widely studied, t's not too far-fetched to imagine a time where doctors will prescribe a trip as a necessary part of a healthy life.

1. Travel Makes You Physically Healthier

You may not feel very healthy when you're throwing up in some foreign land from some lousy food you just ate, but travel substantially boosts your immune system. When you travel, you expose yourself to new bacteria that help you create stronger antibodies. When you move between different locations, you force your body to adapt to thousands of new bacteria, which will make you stronger in the long run.

When you're on the road, you're also proven to be less stressed. Studies have found that after only three days, travelers feel more rested, less anxious and in a better mood while increasing their overall activity and fitness levels. Some studies also show a compelling connection that in certain groups, this change in stress lowers the risk of heart attack and disease. These improvements don't immediately go away after returning home either but will add to lifespan and overall wellbeing.

Travelers are also more active and less stationary on trips. Because there has already been a buy-in to get to your new location, people are more motivated to get out and experience it. You're likely to walk more than you would at home, try a new sport, or engage in a physical activity like hiking or swimming. It's also more likely that these things become a part of your daily experience while traveling, and you're less likely to do sedentary actions like watching tv.

2. Travel Exposes You to Healing Properties

When you travel, you tend to visit sites that you don't have access to at home, and many of those have healing properties. Soaking in the mineral-rich waters of a hot spring, swimming in the salty waters of the ocean, or even just getting out into the sun can expose you to things that will add to your overall wellness. Getting outside exposes us to many properties that can heal, uplift, and rejuvenate. Health and Wellness Tourism has even become a huge part of the travel industry, with a resurgence of people pursuing health-related amenities. Resorts and spas have surged in popularity, as well as activities like yoga, fitness, and lifestyle retreats. Whether that's the focus of your trip or not, you're more likely to participate in a wellness activity while you travel than you would be at home.

3. Travel Creates New Neural Pathways

When you explore, you naturally have to problem solve and adapt to more situations. You have to meet new people, encounter new languages, deal with other cultures, and solve new problems. Neural pathways are created due to environment and habitat and are sensitive to change. When there are new sounds, smells, languages, tastes, and sensations, you're telling your brain to be more aware and to spark new synapses.

When you put your brain in different experiences, it is proven to increase your cognitive flexibility, creativity, ability to make connections and integrate ideas. It's has been shown that those who work and study aboard are more open and emotionally stable. So the more you engage with new environments, the more activated your brain will become, and the more likely you are to stave off brain degradation and disease.

4. Travel Creates Meaningful Social Experiences

Humans aren't meant to be isolated creatures. A crucial part of our physical health comes from having meaningful social connections with others. When we don't have functional interactions, it increases the chance that we'll feel sensations of loneliness, depression, and pessimism. When people stay home, they are more likely to do similar actions every day, which lessens the change of getting out of unhealthy patterns of isolation.

When you travel, it forces you into situations where you have to connect with others. Even if you're alone traveling or backpacking, it puts you into scenarios where the only way to solve specific problems is to meet people and make new friends. You will also be encountering other travelers who will be in a similar state of openness to connection. Engaging in this process will increase your confidence in human interactions.

Travel also deepens the connections with those around you because peak experiences make for more intense and lasting memories. It will also make you less biased as you connect with others who are different than you and increase your skillset for communication and conflict resolution. All of these things are lasting skills that will improve your quality of life, even after your trip is over.

5. Travel Broadens Your Perspective

Travel helps you broaden your view of the world and yourself. By putting yourself into new situations, you have to learn to live outside your comfort zone and find the beauty in different circumstances. While this may make you uncomfortable at times, it allows you to transform how you understand the world.

Studies even prove an increased chance of epiphanies while traveling. There is also an increased ability to problem-solve issues we otherwise have been stuck on. When you're in the middle of a problem, it's often hard to detach yourself from it enough to come to any resolution. By separating from a familiar environment, you gain psychological distance from a situation at hand. Getting away from where you live is important because it's often the only way you can achieve a new perspective.

Travel Helps You Live Longer and Better

With all of these aspects combined, travel is one of those rare things that not only increases your life expectancy but also increases your quality of life. When you take a trip, even if it's short, it boosts your immune system, heart, brain, capacity, connections, and mood, keeping your body healthy inside and out. All of this means that travel increases your chance of living longer and having more fun doing it.
