Slow Your Breathing, Improve Your Life: Less is More

We’ve all been short of breath—whether from exercise or just climbing the stairs. Our natural reaction is often to breathe faster, but here’s the surprising truth: slowing your breath can actually help you breathe more efficiently and feel less breathless.

The Power of Slower Breathing

Research shows that the optimal breathing rate is about 6 breaths per minute. This slower pace enhances oxygen intake, balances blood pressure, reduces inflammation, increases heart rate variability, and boosts vagal tone (which calms your nervous system). But how can this be? It all comes down to something called “dead space” in your airways.

What Is Dead Space?

When you inhale (and we are talking nasal breathing here), not all the air reaches your lungs’ air sacs, where oxygen enters your bloodstream. About 150 milliliters gets trapped in your nasal cavity, throat, and windpipe—this is the dead space. The oxygen in this trapped air doesn’t get absorbed in the lungs, effectively wasting part of every breath.

Why Slower Breathing is More Efficient

When you slow your breathing, you naturally take deeper breaths, which reduces the proportion of air lost to dead space. Here’s the math:

• At 12 breaths per minute (average for adults at rest), each breath is about 500 milliliters, totaling 6 liters per minute. After subtracting dead space, 4.2 liters of usable air reaches the lungs each minute.

• At 6 breaths per minute, each breath can be deeper—up to 1000 milliliters. The total volume is still 6 liters per minute, but with fewer, deeper breaths. In this case, 5.1 liters of usable air reaches the lungs each minute, a 20% increase in breathing efficiency.

Why Does This Matter?

This boost in efficiency means more oxygen in your bloodstream for less effort along wth the other health benefits. This supports better athletic performance, improved endurance, and enhanced altitude adaptation. It may also benefit people with illnesses that affect respiration.

Slow It Down for Better Health

Whether you’re an athlete or just want to feel healthier, slowing your breath can make a big difference. It’s a simple, natural way to breathe smarter, not harder. If you need help getting started or have any medical concerns about changing how you breathe, a breathing coach can guide you.
