What if the ultimate strategy to calm your brain, fight burnout, and boost your happiness doesn’t come from a pharmacy but instead, comes from nature?
 
Most of us spend our days glued to screens, sitting underneath artificial lights, and spending up to 93% of our time indoors. The “indoor epidemic” may be costing us our mental and physical health. Fortunately, a few simple changes could turn things around.
 
My guest today is Dr. John La Puma, a board-certified physician, a pioneer in the field of Eco Medicine, and the author of the new book Indoor Epidemic. He has spent years studying how the natural world directly impacts our biology and mental health. Today, he breaks down the fascinating science of nature and shares the actionable steps you can take to heal your mind and body using the great outdoors.
 
Some of the things we discuss in this episode are:
 

• The number one thing you should do within 60 minutes of waking up to boost your mood and energy.
• Why our modern “indoor epidemic” is quietly causing insomnia, brain fog, and chronic inflammation.
• The fascinating 1984 hospital study that proved just looking at a tree can speed up physical healing.
• The exact “minimum effective dose” of nature you need each week to increase your longevity.
• Why watching the sunset acts as a biological safety signal that guarantees deeper, more restorative sleep.
• How to get the powerful benefits of “Eco Medicine” even if you live in a concrete jungle.
• Simple ways to bring the outdoors inside to lower your cortisol and calm your nervous system.
• Why engaging your senses in nature is a highly effective way to ground yourself and build lasting mental strength.

Key Takeaways:

• Spending as little as two hours per week in nature can improve mental and physical health.
• Morning exposure to natural light is crucial for regulating circadian rhythms and it can improve sleep, boost mood, and increase cognitive function.
• Engaging with nature through senses (listening to the birds, feeling the breeze) can improve mental well-being and relaxation, even during short breaks.
• City dwellers can bring aspects of nature indoors with houseplants, natural light, and scenic views to gain mental health benefits.
• Social interactions in nature, such as going for walks with friends, create added benefits.
