The Power of Nature: Why Biophilia Matters for Health

A growing body of research confirms something many of us intuitively know—spending time in nature is profoundly beneficial for our physical and mental health. A particularly eye-opening study found that simply taking a 20-minute walk in a green space, such as a park, was dramatically more effective at improving well-being than walking in an urban setting. The difference wasn’t just about physical activity or being outdoors—nature itself had a unique impact.

This concept aligns with Biophilia, the idea that humans have an innate connection to nature. While research on the link between mental health and time spent outdoors exists, the role of Biophilia in this connection remains relatively underexplored. However, one of the most compelling areas of study comes from Japan, where the practice of forest bathing, or Shinrin-yoku, has been extensively researched.

A 2019 review published in the journal Environmental Health and Preventive Medicine analyzed 28 studies on forest bathing and uncovered a wealth of benefits. Time spent in nature was shown to:

• Boost the immune system
• Lower blood pressure and heart rate
• Reduce inflammation
• Improve respiratory health
• Enhance sleep quality
• Reduce stress and anxiety
• Improve mood and combat depression
• Sharpen focus and cognitive function
• Promote mindfulness and mental clarity

These findings have influenced the way I work with families. Whether addressing issues like high blood pressure (which has become alarmingly common in teens), anxiety, inflammation, respiratory conditions, or sleep problems, I often encourage patients to incorporate nature into their daily lives. Time and again, I’ve seen nature’s transformative power help break cycles of stress and illness.

Personally, Biophilia has been a guiding force in my life. Years ago, I came across this research, and it deepened my own connection to nature. So much so that my family made a life-changing decision: while on a walk by the ocean, feeling a profound sense of peace and clarity, we stumbled upon a home for sale. Within 15 minutes, we made an offer. Living near the water and being immersed in a natural environment has been invaluable, especially during the pandemic. The daily rhythm of seeing the waves, walking along the hills, and witnessing wildflowers bloom has been a constant source of restoration.

Humans have spent nearly all of our history living in nature—it’s only recently that we’ve become so disconnected from it. But the science is clear: reconnecting with the natural world isn’t just refreshing; it’s essential. Whether it’s a simple walk in the park, a hike through the woods, or even sitting under a tree, embracing our innate connection to nature can yield profound benefits.

Let’s make time for nature. Our bodies and minds will thank us for it.
