Travel has been proven to boost several aspects of physiological health, including your heart and immune system. Research has shown that your immune system is determined not just by your inherited genetics but also by your environment. The more environments you’re exposed to, the stronger your immunity is because you get exposed to different types of antigens that your body builds antibodies against. You can strengthen your immunity when you travel and go to an entirely new place filled with foods, air, and people who carry different antigens.
As far as your heart health goes, travel can improve it both directly and indirectly. Studies have indicated that men who fail to take vacation time away from work for several years in a row are more likely to have a heart attack than men who do take vacations. Likewise, another study showed that women who traveled every year were less likely to suffer from coronary death and myocardial infarction than women who only took a vacation every six years. The reason for this may be twofold: one part is that travel often requires more exercise compared to the sedentary lifestyles most people live, such as going on hikes, walking around a new city, or even walking around the airport. The other reason is that travel reduces stress, and stress is a huge factor in heart disease, as it causes higher blood sugar and blood pressure levels, and this weakens the circulatory system over time.
Speaking of stress, not only have surveys shown that vacation time helps to manage stress and negativity, but travel has also been proven to help you be generally happier, healthier, and more productive. A Harvard study has shown that 94 percent of respondents had the same amount or even more energy after a trip as they did before their trip. In a 2013 study, 80 percent of respondents aged 25 to 70+ agreed that travel helped improve their general mood and outlook, and most of those respondents also said that travel helped reduce their stress.
Studies have also shown that when you do activities like hiking or skiing in scenic areas that involve vistas and being aware of the objects around you, your sense of hopefulness increases. Seeing panoramic views helps you put your life into perspective and understand that there’s more out there beyond just your world at home.
Finally, traveling can help your thinking become more sharp and creative. When exposed to various situations and lifestyles, your brain improves in its ability to think deeply, integrate thoughts, and move between ideas. Studies have also shown that interacting with other cultures increases neuroplasticity and cognitive flexibility.
Experiencing new stimuli such as tastes, smells, and sights can help the brain form new neural pathways, which could help you think more out of the box and become a better problem-solver. This is proven by science. In one study, people who traveled abroad did better on tasks involving creative insights than people who haven’t traveled. In another, creative directors in the fashion industry produced more creative designs when they spent more time traveling.
