In our fast-paced, technology-driven world, it’s easy to overlook the health benefits that come from spending time outdoors. However, Dr. Gregory Duhon, MD, an expert in internal medicine, strongly advocates for the power of nature in promoting longevity.
According to Dr. Duhon, outdoor activities like hiking, surfing, and gardening are more than just hobbies—they are essential tools for reducing stress, improving cardiovascular health, and extending lifespan.
Reducing Stress through Nature
Chronic stress is one of the leading contributors to premature aging and many chronic diseases. Spending time in nature is a simple but powerful way to alleviate stress. “One of the most effective hacks for longevity is simply spending time outdoors,” says Dr. Duhon. “Nature has a calming effect on the body and mind, which lowers cortisol levels, reduces blood pressure, and ultimately promotes longer life.”
Studies have shown that people who spend time in green spaces experience lower levels of anxiety and depression. Whether it’s hiking through a forest or walking in a local park, Dr. Duhon recommends spending at least 30 minutes outside every day to reap the mental health benefits.
Cardiovascular Health: Moving in the Great Outdoors
Physical activity is essential for heart health, but outdoor activities offer an extra boost. “Outdoor exercise like hiking or surfing not only works the body but also engages the mind in a way that traditional indoor workouts often do not,” explains Dr. Duhon. “This combination of physical and mental engagement can have a profound impact on overall health.”
Hiking, for instance, combines cardiovascular endurance with the added benefit of being surrounded by nature, which enhances the mood-boosting effects of exercise. Surfing, on the other hand, offers a full-body workout while engaging with the ocean—a natural environment that promotes both physical and emotional well-being.
According to Dr. Duhon, cardiovascular health is one of the most significant factors in longevity, and outdoor activities provide an enjoyable way to maintain a healthy heart. Regular physical activity outdoors improves blood circulation, strengthens the heart, and lowers the risk of heart disease.
The Healing Power of Gardening
For those looking for a lower-impact activity, gardening provides a therapeutic way to connect with nature. Dr. Duhon explains that gardening is not only physically engaging but also mentally soothing, which makes it a powerful tool for longevity.
“Gardening is a form of light physical exercise, but its true benefit lies in the mental relaxation it provides,” says Dr. Duhon. “Tending to plants, growing your own food, and simply spending time in a garden can reduce stress and improve mental clarity, both of which contribute to a longer life.”
Additionally, gardening has been shown to improve dexterity and coordination, especially in older adults, promoting physical health well into advanced years.
Nature’s Role in Mental Resilience
The mental health benefits of spending time outdoors go beyond just reducing stress. According to Dr. Duhon, nature has a restorative effect that helps improve focus, enhance cognitive function, and build mental resilience.
“People who regularly spend time in nature tend to have better mental health and are more resilient in the face of stress,” notes Dr. Duhon. He encourages patients to take breaks from their busy schedules to reconnect with nature, whether through short walks in the park or weekend getaways to natural settings.
Research supports Dr. Duhon’s claims, with studies indicating that spending time in natural environments can improve memory, creativity, and cognitive function. By regularly engaging with nature, individuals can build stronger mental resilience, which not only improves the quality of life but can also contribute to increased longevity.
Vitamin D and the Immune System
Another significant benefit of spending time outdoors is increased exposure to sunlight, which helps the body produce vitamin D. Dr. Gregory Duhon, MD, highlights the importance of vitamin D in supporting the immune system, bone health, and its indirect effect on inflammation.
“Vitamin D plays a crucial role in bone health and the immune system’s response to potential dangers,” explains Dr. Duhon. “It indirectly affects the body’s inflammatory response, particularly when comparing individuals with autoimmune disorders to those with fully functioning immune systems.” While vitamin D is important for immune function, Dr. Duhon notes that, in healthy individuals, vitamins C and E are more directly associated with reducing inflammation.
By spending time outdoors, people naturally increase their vitamin D levels, which supports the body’s ability to fight off illness and promotes longevity. Dr. Duhon recommends balancing sun exposure with proper skin protection, such as wearing sunscreen, to maximize the health benefits while minimizing risks.

Conclusion: Nature as a Longevity Boost
The benefits of spending time in nature are vast and well-documented. Whether through intense activities like surfing and hiking or more relaxed pastimes like gardening, outdoor engagement is an essential factor in promoting longevity. Dr. Duhon advocates for incorporating outdoor activities into daily life as a way to reduce stress, improve cardiovascular health, boost mental resilience, and strengthen the immune system.
“As an internal medicine physician, I’ve seen firsthand the power of nature in helping people lead longer, healthier lives,” says Dr. Gregory Duhon, MD. “Taking the time to step outside, breathe fresh air, and engage with the natural world can be one of the most effective ways to extend your lifespan.”
