The Secret to Proper Breathing During Exercise for Peak Performance

It's simple. For our bodies, tissues, organs, and muscles to function correctly, they need an adequate supply of oxygen. The quality of your breath plays a pivotal role in how well your body handles movement.

Movement and breath are inextricably linked. In this article, you'll discover why it's so crucial to breathe through your nose, even during intense physical activity.

How to Breathe Functionally During Any Sport

We exercise to be healthy. We track our heart rate and our times, but we rarely think about how we're breathing—whether it's through our nose or our mouth. We just... breathe.

So, let's explore how to breathe functionally during activities like running, hiking, cycling, skiing, tennis, volleyball, basketball, swimming, and more to ensure our muscles and tissues get the oxygen they truly need.

The Power of the Nasal Inhale

When you inhale through your nose, the air is warmed, humidified, and filtered. Critically, this process also significantly increases oxygen uptake thanks to nitric oxide, which is produced in the nasal sinuses and carried into the lungs with each breath.

A proper nasal inhale directs air into the lower lobes of the lungs, where the most efficient gas exchange with the blood occurs. If air doesn't reach these lower lobes, blood can stagnate there, potentially becoming a source of health issues.

For air to properly fill the lungs, the diaphragm must descend like a piston, drawing air into every part of the lungs. The benefits of this diaphragmatic action are immense:

Core Stabilization: The diaphragm provides crucial stability for the lumbar spine.
Internal Organ Massage: Its movement gently massages the intestines and other internal organs.
Cardiovascular Support: It assists the heart in circulating blood to all tissues.
Lymphatic Stimulation: It helps activate and move the lymphatic system.
Parasympathetic Activation: It stimulates the "rest and digest" part of our nervous system, which has a calming effect. I absolutely love this "meditation in motion."

The "How": Slow, Gentle, and Effective

Inhale through your nose slowly and gently. This prevents the nasal mucosa from collapsing (a phenomenon known as the Venturi effect).

By breathing slowly and gently, you also draw more NITRIC OXIDE (NO) from your nasal sinuses into your lungs. Nitric oxide is a powerhouse molecule that disinfects the nasal passages (it's antibacterial and antiviral) and also acts as a potent vasodilator. It widens both the airways and blood vessels, which helps prevent high blood pressure and blockages, allowing for superior oxygen transfer.

OXYGEN is the fuel your muscles need to work efficiently.

For athletes, NITRIC OXIDE is a game-changer. It relaxes the inner muscles of the blood vessels, causing them to widen and improve blood flow throughout the circulatory system. Better circulation means better delivery of nutrients and oxygen to your tissues.

NITRIC OXIDE also reduces the buildup of lactic acid by delivering more oxygen to working muscles.

The CO2 Paradox

The amount of oxygen our muscles, organs, and tissues can actually use doesn't depend on the amount of oxygen in our blood, but rather on the amount of carbon dioxide (CO2). It is CO2 that allows oxygen to be released from red blood cells to nourish our organs, tissues, and muscles.

When breathing through the nose, the mouth remains closed and the tongue rests on the roof of the mouth. The tongue not only supports the head and shapes the jaw, but it is also part of the deep fascial line, which is our functional core. - What is a Truly Functional Core?

The High Cost of Mouth Breathing

So WHY do I constantly see athletes flying by with their jaws dropped, breathing through their mouths? Yes, they might seem faster in the short term.

But when you breathe through your mouth, the tongue often falls back into the throat, narrowing the airway. The diaphragm can't work effectively, and you begin breathing shallowly into the upper part of your lungs.

By doing this, we consciously deprive our muscles of oxygen. This leads to constricted blood vessels, an overworked heart, impaired lactic acid clearance, and activation of the sympathetic nervous system (the "fight or flight" stress response). You miss out on all the benefits of nasal breathing mentioned earlier.

This chronic over-breathing also restricts blood flow to the brain and extremities.

Over time, this pattern can bleed into your daily life and even your sleep, potentially leading to anxiety, asthma, fatigue, insomnia, snoring, and heart problems.

The result is often a constantly congested nose and a body stuck in a state of stress. - Breath in Motion and in Context

I truly love understanding these connections. For over a year now, I've been consciously adapting my movement to my breath, and it works. I don't push for performance; instead, I enjoy the movement, and my body does too.

Let Your Breath Lead the Way

The quality of your breath is fundamental to your body's health, and your movement should adapt to your breath—not the other way around.

If we can set aside our ego and the pressure to perform, close our mouths, and start breathing through our noses during activity, we won't just improve our breathing quality. We'll enhance our overall physical condition and health—and you might just be surprised by what happens.
