"Anti-aging", "frozen age" and "eternal youth" are the pursuits of many people, and some Australians even go overseas to do medical beauty for this purpose.
But new research has found that travel is the key to anti-ageing.
Researchers at Edith Cowan University in Perth have found that travel is not only good for mental and physical health, it can also make people look younger.
Fangli Hu, a Chinese researcher at the university, said: "Ageing is an irreversible process that can be slowed down although it cannot be stopped."
Their research shows that exposure to new cultures, languages, environments, and relaxing activities can stimulate the stress response, increase the metabolic rate, and improve the body's ability to self-organize.
Travel may also trigger an adaptive immune system response.
"Simply put, the immune system becomes more resilient," Hu explained.
"This may allow the body to secrete hormones that help in tissue repair and regeneration, strengthening the function of the self-healing system."
In addition, the process of travel is not without physical exercise.
And exercise can improve blood circulation, accelerate the transport of nutrients and waste excretion to maintain the body's ability to heal itself.
Australians are well aware of the mental health benefits of time off, with more companies writing "doona days" - days off work for personal health or psychological reasons - into their employment contracts and the four-day week becoming a hot topic.
But this is the first time a global study has revealed the anti-aging benefits of taking time off.
"Traveling is part of a healthy lifestyle that contributes to physical and mental health and also helps fight aging," Hu said.
"When traveling, you can immerse yourself in new environments - especially healing ones like forests and beaches - that help reduce stress and improve people's mental health."
When traveling in a different place and away from everyday life, people are more likely to be active and adventurous.
"Travel can promote physical activity, such as walking, hiking, cycling - many activities can enhance people's cardiovascular health, metabolism, muscle tone, and many other body functions," Hu said.
Moderate exercise also benefits the bones, muscles and joints, and supports the body's anti-wear system."
Travel can also force us to interact - interaction with other tourists, locals and even animals can improve people's mood."
Travel can also reduce loneliness and improve cognitive function. Travel can even promote healthy eating -- try fresh, local foods."
Of course, these benefits of travel don't mean you need to spend a lot of money and travel far away.
"Even weekend travel may have potential health benefits. It depends on each person's situation."
So, in order to keep yourself younger, travel more!
