By 60, You’ve Probably Been Oxygen Deficient for a Decade
LiveO2 VP Tom Butler joins the Whole Life Challenge podcast to explain what’s really happening to your oxygen levels as you age — and what you can do about it.
What Tom Covers
- How to know if your blood oxygen level is normal — and why most people never check
- How supplemental oxygen and EWOT (Exercise With Oxygen Therapy) can prevent and treat chronic disease
- Why by the time you’re 60, you’ve probably been oxygen deficient for a decade
- The rest and recovery balance — why too much rest actually works against you
- Which organs get oxygen first — and which ones are silently running low
- Blood stasis and stagnation — how your body quietly shuts down parts it thinks you don’t need
- What vascular inflammation is and how oxygen training addresses it at the root
The Oxygen Debt Nobody Talks About
Most people think oxygen deficiency means gasping for air. It doesn’t.
Oxygen deficiency builds slowly. Over years. You don’t feel it happening. But your body notices.
Here’s how it works. Your body has a priority list for oxygen. Your brain and heart get served first. Everything else — joints, muscles, peripheral tissue — gets whatever’s left. As you age, circulation slows. Blood vessels narrow. The oxygen that used to reach every corner of your body starts falling short.
By the time you’re 50, parts of your body are running on less than they need. By 60, that oxygen debt has likely been accumulating for 10 years or more.
This is called blood stasis. It’s the process of your body “turning off” the supply to areas it considers low priority. Think of it like a drought. The city cuts water to parks before it cuts water to hospitals. Your body does the same thing — and over time, those “parks” start to wither.
The tissues that go low on oxygen don’t scream. They just quietly stop working as well. You notice it as fatigue, joint pain, slower recovery, brain fog — things most people blame on “getting older.”
Then there’s vascular inflammation. When blood flow is restricted, the vessel walls get irritated. They swell slightly. That swelling makes the restriction worse. It becomes a cycle that ordinary exercise can’t fully break.
Adaptive Contrast training — alternating between enriched oxygen and reduced oxygen during exercise — creates a powerful stimulus. The body responds by reopening dormant blood vessels and pushing oxygen into tissue that hasn’t been properly supplied in years.
“By the time you’re 60 years old, you’ve probably been oxygen deficient for a decade.”
Common Questions
EWOT stands for Exercise With Oxygen Therapy. You exercise while breathing a higher concentration of oxygen than normal air provides. Regular exercise improves circulation, but it works with whatever oxygen is available. EWOT gives your cardiovascular system more fuel at the exact moment it’s working hardest — which drives oxygen deeper into tissue, including areas that have been chronically underserved.
Adaptive Contrast is a training method that alternates between breathing enriched oxygen and reduced oxygen during exercise. The contrast between high and low creates a stronger cardiovascular response than either state alone. During the high-oxygen phase, blood vessels open wide. During the low-oxygen phase, the body is pushed to work harder. Together they stimulate dormant circulation pathways that standard exercise can’t reach.
A pulse oximeter measures blood oxygen saturation (SpO2). A reading of 95–99% is considered normal at rest. Below 95% at rest is worth paying attention to. But the more important number is how quickly your saturation drops during exercise — and how fast it recovers. Many people who test normal at rest show significant oxygen debt under physical load. Tom discusses this in the episode.
Yes — and this is a key point Tom makes in the episode. Rest is essential for recovery, but extended inactivity accelerates blood stasis. When you stop moving, circulation to peripheral tissue drops. Vessels that aren’t being used regularly begin to constrict. The body is adaptive — if you tell it you don’t need something by not using it, it starts to reduce the supply. Consistent movement, even gentle movement, keeps those pathways open.
