Hyperbaric Oxygen Therapy: How Long Do the Benefits Really Last?

When people consider starting a new treatment, one of the first questions they often ask is: How long will the results actually last? That’s especially true for therapies like Hyperbaric Oxygen Therapy (HBOT), which, while gaining traction, is still unfamiliar to many. After all, no one wants to invest in a treatment if the benefits vanish within days.

At Morelli Medical, we believe patients deserve clear, trustworthy answers, especially when it comes to something as promising as HBOT. So, let’s break down what science and experience tell us about the duration of HBOT’s effects and how you can make the most of them.

Understanding How HBOT Works

Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized environment. These sessions typically take place inside a specialized chamber where the atmospheric pressure is increased, usually between 1.3 to 2.0 ATA (atmospheres absolute) to help your lungs absorb more oxygen than normal.

This high-oxygen environment has been shown to:

Accelerate healing by boosting tissue oxygenation

Reduce inflammation

Support neuroplasticity and brain recovery

Stimulate collagen production and cell regeneration

But the big question remains how long do these benefits actually stick around after the therapy ends?

1. HBOT Effects Can Last Up to 12 Months or More

In general, the positive results of HBOT can last anywhere from six months to a full year. Many patients report sustained improvements in energy, cognitive function, wound healing, and overall well-being for months after completing a treatment cycle.

Some people even experience longer-lasting effects, especially when HBOT is used to support chronic conditions, post-surgical recovery, or neurological health.

2. But It’s Not Instant, Consistency Matters

HBOT isn’t a one-and-done solution. It works gradually by increasing oxygen delivery to damaged tissues and enhancing the body's natural healing processes.

Most medical providers (including us at Morelli Medical) recommend a course of 20 to 40 sessions, usually spread out over 5–6 weeks. That consistency is key. The more your body adapts to the pressurized oxygen environment, the longer the effects tend to last.

Factors That Influence How Long HBOT Effects Last

✔️ Treatment Frequency and Duration

As mentioned, a full protocol of 20–40 sessions gives the best results. Skipping sessions or cutting the program short can limit the therapy’s impact.

✔️ Your Overall Health

Your body’s baseline health plays a big role in how long the benefits stick. Those with stronger immune and cardiovascular systems tend to respond more robustly to HBOT.

✔️ The Condition Being Treated

Some conditions, like chronic wounds or long COVID, may respond with longer-lasting results. Others, like acute sports injuries, might see a quicker (but shorter-term) recovery boost.

✔️ Post-Treatment Lifestyle

Healthy choices after your therapy like staying active, eating a balanced diet, and managing stress can extend the positive effects of HBOT.

What to Avoid Before and After Sessions

To get the most out of your therapy, a few simple precautions go a long way:
Avoid going in sick: Colds and congestion can worsen under pressure.
Don’t smoke or drink alcohol during your treatment period.
Stay hydrated and eat lightly before sessions.
Follow your provider’s guidance about medications or supplements.

Frequently Asked Questions About HBOT Duration

How long does it take to feel the effects of HBOT?

Most patients begin noticing results after the first 5–10 sessions, but lasting improvements typically develop over a full course of 20+ sessions.

How often should I do HBOT?

That depends on your condition and goals. Our team at Morelli Medical will personalize your treatment schedule based on your needs.

Does HBOT help with hair growth or skin health?

Yes! Increased oxygen levels support collagen production, circulation, and tissue regeneration—factors that can help improve skin tone, reduce wrinkles, and even stimulate hair follicles. Read more here.
