Excessive Yawning: Your Body is Trying to Tell You Something

We all yawn—but when yawning becomes constant, it might be more than just tiredness. Your body has clever ways of telling you something isn’t quite right, and excessive yawning is one of them.

The Science Behind the Yawn:

Yawning is often linked to nervous system regulation. It can help:

• Cool your brain
• Increase alertness
• Adjust blood flow and oxygen levels

But yawning isn’t always just about needing a nap! It can also signal breathing pattern dysfunction. If your breathing is too fast, shallow, or irregular, your body might be trying to correct your oxygen and carbon dioxide balance—hence the yawns.

When It’s Just Your Nervous System:

Sometimes, yawning is a simple way your nervous system regulates itself. Stress, tension, or changes in alertness can trigger it.

When It’s a Breathing Signal:

Excessive yawning can indicate:

• Over-breathing (hyperventilation)
• Air hunger or low CO₂ tolerance
• Inefficient oxygen delivery despite normal breathing

In these cases, yawning is your body’s subtle alarm bell, nudging you to check in with your breathing habits.

What You Can Do:

• Notice your breathing: Are you shallow or fast?
• Slow, diaphragmatic breaths: Encourage proper oxygen-carbon dioxide balance
• CO₂ tolerance exercises: Gradually train your body to hold breath comfortably
• Seek guidance: If yawning is interfering with your day, a breathing retraining plan can help

Closing:

Yawning isn’t just a cute quirk—it’s your body speaking. Listen, understand, and respond. Your breath is more powerful than you think!
