An Insiders Look at Hyperbaric Oxygen Therapy and Post Concussion Syndrome.

Bryan Johnson is a wonderful hyperbaric oxygen therapy (HBOT) clinician who I have been personally treated by many times. I found amazing results within my first few visits with Bryan including: clearer thinking, better focus, higher energy, desensitization of my scalp, headache evaporation, an overall sense of well being, and many other improvements. Bryan has conducted thousands of HBOT sessions in Los Angeles at his clinic O2 UP ( I have had such a success story with Bryan and HBOT. Because of this, I wanted to pick Bryan's brain regarding HBOT and head injuries and share it with all you that may be interested. Here's what Bryan had to say. 

Bryan Johnson - a HBOT Clinicians perspective. 

I’ve seen some great healings occur at O2 UP. The patients we’ve helped, range from those suffering from the effects of chemotherapy, to those with migraine headaches, patients with Parkinson’s, chronic fatigue, lyme disease, autism, professional athletes healing after an injury, and so many others.

 While I’ve seen impressive healing within these groups of conditions, traumatic brain injuries (TBI) and mild traumatic brain injuries (mTBI) is where I see the most consistent healing occur.

 Yet with all of the results I see firsthand, I’m continually confused by the fact that more doctors don’t  educate their patients  about HBOT as an option after a TBI. If nothing else, I hope that this post can at least educate you about what HBOT is, how it works, why there are discrepancies in reporting its efficacy, and what I’ve seen firsthand.  


What Is Hyperbaric Oxygen Therapy?

  To put it simply, HBOT has two main components -- pressure and concentrated oxygen.  During treatments the patient is usually lying down in pressurized chamber breathing concentrated oxygen. The pressure created by the chamber helps the body to become saturated with oxygen.  You can think of this process as being somewhat analogous to creating soda water.  To create soda water you need carbon dioxide, water, and pressure.  The pressure pushes the CO2 into the water giving you a fluid that is holding a gas.  In HBOT, the gas we use is oxygen and your body, being made up of mostly water, becomes the vessel for that oxygen.  This process is grounded firmly in physics and is pretty simple for most people to get their heads around.  How the body then uses the oxygen towards its advantage becomes a more hotly debated topic.  

How does Hyperbaric Oxygen Therapy Work?

To those that see HBOT work on a daily basis, we would tell you that hyperbarics super-saturates the body with oxygen, decreases inflammation, promotes stem cell growth, and helps to grow new blood vessels (a process called angiogenesis).  What all of this is basically saying is that HBOT promotes healing!  Whether this healing happens with a wound that won’t heal on a diabetic patient’s foot, or a wound that can’t be seen since it’s internal, like the bruising you might find on a concussed brain; the benefit is all the same.  Oxygen helps the cells to promote healing in these areas.  

Doctors don't prescribe HBOT. Why?

Surprisingly enough, many doctors don’t feel that hyperbarics provides much benefit to patients.  The feeling is often that the body is already delivering enough oxygen through its normal respiratory process to provide the oxygen needed for healing.  Many doctors also feel that the studies done on hyperbarics for many conditions have not conclusively proven that there is benefit. This is why they won’t tell their patients about it or they flat out discourage its use.  

However, to gain better perspective on this difference in opinion I think we should look at the principles of how oxygen would support the brain after an injury, how some of the studies on HBOT and brain injuries were conducted, and some first-hand experiences.  From there you can make your own conclusions.  


Your Brain needs oxygen

  Many people aren’t even aware of how energy-intensive of an organ their brain is.  We can better understand this by looking at the sheer amount of oxygen that it utilizes. Your brain uses 20% of the oxygen your body takes in, this is a huge amount for an organ that only weighs about 3 pounds. When an injury to the brain is sustained, there are a chain of events that ensue, directing blood-flow, releasing chemicals throughout the brain, and processes meant to deal with the shock of the injury.  However, due to these reactions and the inflammation that takes place, your injured brain isn’t necessarily getting the oxygen it needs to adequately heal.  This is the theory on why getting oxygen to the brain through the use of hyperbarics is thought to work.  Even without an injury your brain needs 20% of your body’s oxygen intake, so after an injury wouldn’t it make sense to give it even more to help with repair work?  Many people would intuitively arrive at this reasoning and in fact, there are a good number of doctors that believe HBOT is effective for these reasons.  However, there are still a large number of doctors who don’t see hyperbaric oxygen therapy as being beneficial for brain injuries.

A rebuttal to those who say HBOT is not effective. 

  Studies done on hyperbarics and brain injuries that were deemed somewhat inconclusive.This has fueled the disagreements on the benefit of oxygen therapy for brain injured patients.  Some of the “conclusions” from the studies done on concussions, PTSD, and TBI being treated with HBOT have said that the results prove that hyperbaric oxygen does not conclusively benefit these conditions.  This has caused many doctors to automatically write-off hyperbarics as a treatment.  However, if doctors were to look deeper into these studies, they would find a whole slew of problems with the application of studies themselves.  Dr. Paul Harch, who is one of the world’s leading experts on HBOT in use with brain injuries, talks about the tragic faults of these studies here:  Basically, these studies were either headed by doctors with little to no HBOT experience, the treatment pressures were too high for brain injuries, the sham (or placebo) treatment was not actually a true sham treatment, or results were not properly represented.  This has led to a lot of miseducation about HBOT, that has kept many brain injured patients from even knowing that HBOT could be a viable option for them.  

Stories from patients themselves

As I’ve stated earlier, I have treated people with such a wide range of conditions at our clinic.  But truly, some of the stories that I love most have been of the effect HBOT has had on brain injuries.  Now, this is one issue that many naysayers of hyperbaric medicine have.  They say that many of the evidence is purely anecdotal.  However, having already discussed the issues with many of the studies, I think it’s important to share some of the firsthand accounts that I’ve had with brain injured patients.  The healing that has taken place has been clear and can be attributed to nothing but the oxygen sessions they are doing.  I’m not giving these stories as a foretelling of what you can expect from the therapy.  Rather they are to just show what can be possible.  

David - four concussions in five years...

The first story is of a gentleman that we’ll call David.  David was 82 years old when he first came in and had suffered from four concussions within a five year span.  It had been two years since his last concussion and he was plagued by continual headaches, brain-fog and fatigue that was keeping him from partaking in his once very active life.  The funny part of this story was that David actually had a long history with hyperbarics, but that focused more on its use in underwater medicine applications.  It was only recently that he realized that HBOT could be beneficial for his post-concussion symptoms.  After a number of phone calls with David, he finally came in to start his HBOT protocol.  After only five sessions, David’s constant headaches that he had had for two years completely went away and his thinking was much clearer.  David also noted that his energy levels were much improved and this caused him to want to continue with HBOT as a part of his general health routine.  Now more than 18 months after his first sessions David has happily been headache-free.  

Andrea 10 months post injury 

The second story is of a 15 year old girl that had a head injury from being hit by a car that caused her to be in a coma for two weeks.  The girl, who we'll call Andrea, came to me 10 months after her injury.  Luckily, Andrea had already made significant progress in her rehabilitation, but she was still suffering from headaches, lack of ability to concentrate, and anxiety due to her accident.  While she was able to slowly integrate back into school, she was not able to read or focus on her studies.  After a couple weeks of hyperbaric treatments Andrea’s mother called and said that Andrea wanted to tell me something.  As soon as Andrea took the phone I could sense the excitement in her voice.  She went on to explain that before her accident she loved to read.  However, after her accident she wasn’t even able to finish a single page because she just couldn’t focus.  Since starting her treatments though she had now finished one book and was part-way through her second book.  This was all within about 15 sessions of hyperbaric oxygen therapy.  Both Andrea and her mother attribute this change to HBOT, because Andrea wasn’t pursuing any other new therapies and there was such a rapid change.  

Brad could only see in black and white after his injury...

For the last story, let me start by saying that I was supposed to have this article finished a couple weeks ago.  However, as I was writing this I had another client come in with post concussion syndrome.  I decided to hold off a couple weeks to see how my client does.  It just seemed like rather serendipitous timing to have a new client with a concussion right at the same time I’m starting this article!  So here’s what has happened.  This last client is a 43 year old named “Brad” that had his last concussion three years ago.  He was biking in the desert and hit his head in a crash against a rock that had him seeing in only black and white.  Since the accident Brad has been on the prescription drug Tramadol to take the edge off the CONSTANT headaches that he says are usually between a 7-9 in severity on a scale of 10.  After living with these headaches for three years Brad finally heard of hyperbarics and decided to give it a try.  At the point of writing this article, Brad has not taken Tramadol once in four days.  Brad says that he used to try going one day without taking Tramadol to see how it would feel.  When he did this he would need to take a nap on the floor of his office just to deal with the pain of his headaches.  Now HBOT he has not had to take Tramadol at all!   Brad still has more sessions to go with hyperbarics, but even this early into his treatment he’s already another positive story on the effects of hyperbaric oxygen with head injuries.


With my experience, no one can tell me that hyperbaric oxygen therapy isn’t beneficial to those with head injuries.  I see the results too frequently and consistently to not be confident in this healing modality.  However, with that said, it’s up to each individual to chose the therapies they want to incorporate into their healing journey.  My hope is that this article at least gives added perspective into the possibilities of hyperbaric oxygen in use with head injuries.  Talk to people whose lives have been touched by HBOT, do your research, and I wish you the best in your healing!

Saunas, Ice Baths, and Post Concussion Syndrome.

I come from a strongly Finish and Italian family. I have 3 middle names Toivo Olavi Maki, all of which are Finish. I traveled to Finland when I was 13 to spend time with family and experience my homeland. What I found very interesting about Finnish culture is how integrated Saunas are in society. 99% of Finns sauna at least once a week. There are 3 million saunas for a country with only 5.3 million people. Finns believe that saunas are a key part of staying healthy and removing toxins from the body. Using a sauna for 15 minutes can increase your white blood cell count; which can boost your immune system, alleviate chronic pain, and increase joint mobility. A traditional Finnish sauna routine consists of getting in the sauna for 15-20 minutes then jumping into a ice cold body of water for 2 minutes. Ultimately, this fluctuation of hot and cold temperatures has a great neurological effect on the body. Ice cold temperature on injuries have been shown to have an anti-inflammatory effect allowing for faster recovery times and pain reduction. Getting back to my roots was especially helpful after sustaining a massive concussion and neck injury when I was 17.

Shroom TECH Sport by Onnit

Months after the initial injury I was still facing severe nerve pain on an hourly basis. I had hit my head more than 5 times and suffered a compression fracture to my neck. I developed something called allodynia (hypersensitivity of the nerves). This is a terrible condition to have especially when it's associated with a head injury. Imagine a simple pat on the back feeling like nails exploding in your brain. It's something that is very hard to explain to people because unless you are going through it, it seems as if you are exaggerating.

After many failed prescriptions and medications, one of my doctors recommended treating my pain with hot and cold therapy. I used this fluctuation between hot and cold just like the Finns do, but to treat my allodynia and nerve pain from my post concussion syndrome. The effects were incredible, giving me relief from my headaches and toned down my allodynia. I used this treatment of about twice a day for six months with great success. Not only was I reducing my pain levels, but I was becoming much more energized. In addition to this hot and cold therapy, I take daily cold showers.  I find many of the same benefits come from this, and it's much easier to integrate into your daily routine. Cold showers have shown to Increase your bodies circulation, immune system, mood, and alertness.

If you don't have access to a sauna dont worry. You can get similar results from a hot shower and an ice bath. For me I would put my head and or body into a tub of water and ice. Sometimes I will just use a sink, submerging my head for headache relief.  Generally I will hold myself under for 30 seconds - 2 minutes (you may get a brain freeze, but trust me its worth it) and jump into a hot shower. I would repeat this process until my pain resided.
