The Darin Olien Show | Why Your Lungs Need Hydration Too

The Darin Olien Show | Why Your Lungs Need Hydration Too


We all know it’s necessary to drink plenty of water to hydrate the body. However, did you know your lungs need hydration, too? 

Dr. David Edwards wants to make sure your lungs aren’t dry.

David is a scientist, inventor and writer. His latest invention, FEND, was Time Magazine’s Best Invention of the Year in 2020. All of Dr. Edward’s inventions, startups and creative spaces, both in France and the United States, have helped pioneer a new way of creating. He’s known for blending art, science and design in such a way that impacts our everyday life significantly. David’s most recent book, Creating Things That Matter, won the Nautilus Book Award in the category of creativity.

Between 2001 & 2019, David was a Professor of the Practice of Bioengineering at Harvard University. It was his time there that led to the startup of FEND. This hygiene product for the lungs uses a gentle, ultrafine mist made up of a precise blend of hydrating salts. Breathing in the mist strengthens your upper airways’ natural ability to clean the air you breathe. 

It’s hydration for your lungs!

It blows my mind that something so simple can make such a big difference. I use my FEND daily, and I was so excited to have Dr. Edwards on the show to explain the science behind it. You hear me talk about hydration all the time- but I’ve never focused on the hydration of the lungs, specifically. The truth is, most of us are probably walking around with dry lungs right now, and don’t even realize it. Our lungs need hydration, but it’s not as simple as drinking a glass of water.

If you’re lucky enough to live by the ocean, your lungs are probably in great shape! However, the rest of us aren’t as lucky. Dr. Edwards breaks down why the air we breathe in today’s world is drying out our respiratory systems. We also get into the wonders of the olfactory system, and how we’ve lost touch with our senses over the years. This is a science-packed episode, for sure. But David is so great at explaining the heavy stuff. I think you’re really going to love this one! And so will your lungs.
