Does Hyperbaric Oxygen Therapy Make You Tired? What Science Says

## Does Hyperbaric Oxygen Therapy Make You Tired? What Science Says

If you are exploring hyperbaric oxygen therapy (HBOT) as a treatment for chronic wounds, sports recovery, or neurological conditions, you may wonder about its side effects. One common question we hear is, **Does Hyperbaric Oxygen Therapy Make You Tired?** While HBOT is generally well-tolerated, temporary fatigue can occur. This article breaks down the science behind this phenomenon, explores why it happens, and offers tips to manage energy levels post-session.

Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized chamber, typically at 1.5 to 3 times atmospheric pressure. The increased pressure allows oxygen to dissolve into the blood plasma, reaching tissues with poor circulation. This process enhances cellular repair and reduces inflammation.

### How HBOT Affects Energy Levels in the Body

Many patients report feeling tired, relaxed, or even drowsy after a session. But is this fatigue caused by the therapy itself or by other factors?

#### 1. The Oxygen Paradox: Stimulation vs. Relaxation

At the cellular level, oxygen is a fuel for mitochondria, the “powerhouses” of your cells. Higher oxygen availability boosts ATP (energy) production. Short-term exposure to hyperbaric oxygen (around 60-90 minutes) can increase alertness and mental clarity.

However, for some people, the quiet environment and pressurized chamber create a deeply relaxing experience. This can mimic a meditative state, leading to post-session lethargy. It is not a sign of energy depletion but rather of near-therapeutic relaxation.

#### 2. Oxygen Toxicity Symptoms

In rare cases when oxygen levels exceed safe limits (usually above 2.4 ATA or with prolonged sessions), you may experience oxygen toxicity. Common symptoms include tunnel vision, ringing in the ears, and muscle twitching. Fatigue is a late symptom of mild oxygen toxicity, but it typically resolves quickly after the session ends.

#### 3. Cellular Repair Work Requires Energy

Another scientific perspective: HBOT amplifies the activity of reparative enzymes. If your body is healing wounds, fighting infection, or recovering from injury, the metabolic demand for repair increases after HBOT. This might explain why some feel tired, as the body diverts resources to healing.

| **Factor** | **Effect on Energy** | **Scientific Mechanism** |
|————|———————-|————————–|
| Relaxation in chamber | Drowsiness | Parasympathetic activation |
| Increased oxygen | Short-term high energy | Mitochondrial boost |
| Healing response | Mild fatigue | Increased metabolic demand |
| Hyperoxia (too much oxygen) | Potential tiredness | Oxygen toxicity (rare) |

### Common Myths vs. Facts About HBOT and Fatigue

**Myth:** HBOT makes you permanently exhausted.
**Fact:** Session-related fatigue typically resolves within a few hours. Most patients feel more awake the next day.

**Myth:** Tiredness means the therapy is not working.
**Fact:** In many cases, fatigue indicates that your body is using the added oxygen effectively to repair damaged tissues.

### Who Is More Likely to Feel Tired After HBOT?

– **Chronic wound patients**: Healing large wounds requires immense energy, which may contribute to temporary fatigue.
– **Patients with autoimmune conditions**: The anti-inflammatory effect of HBOT may reduce systemic inflammation, initially making you feel lethargic before long-term improvement.
– **First-time users**: Anxiety from the confined chamber experience can physically drain energy.
