It’s hard to believe that something as natural and automatic as breathing could be done incorrectly. But according to prolific science journalist James Nestor, human breathing has regressed. With evolution in play, our modern lifestyle has devolved the physiology of our mouths and nasal cavities in such a way that our breathing has shifted from nose to mouth. However, it’s a problem that can be simply solved and the rewards can be enormous. The secret to better sleep, more energy, lower blood pressure, lower anxiety, and the elimination of snoring, sleep apnea, ADHD, and so much more is better breathing.

It’s so easy that a lot of people think, “That’s not going to do anything for me.” But look at the science and you’ll find otherwise.

Researchers have long noted that the development of softer foods has impacted human facial structure. Without the kind of hard chewing our predecessors practiced, jaws recede, faces grow less forward and mouths are smaller. Essentially, our breathing pathways are diminished, resulting in more mouth breathing. But according to scientific data in James Nestor’s book, nasal breathing is the gold standard. It filters toxins, moistens the air, and oxygenates our bodies more effectively. The good news is, despite the negative effects of smaller airways, we can learn to breathe deliberately through our noses, absorb more oxygen, and realize all of its benefits.

You can gain incredible health benefits by adjusting the way you breathe. Adds Nestor, “There is something here that can benefit you, doesn’t take a lot of time, doesn’t take a lot of effort, we know it works, and here it is. Why not explore it?”
