Introduction To Hyperbaric Oxygen Therapy & Heart Rate Variability.

This is a case report looking at the effect of hyperbaric oxygen therapy (HBOT) on heart rate variability (HRV) as measured by the Oura ring.

While HBOT is well known for its ability to treat certain medical conditions, less is known about the impact on daily heart rate variability for those interested in improving physical recovery, sleep and longevity.

About Hyperbaric Oxygen Therapy (HBOT)

Hyperbaric therapy (HBOT) is a treatment that involves breathing pure oxygen in a pressurized chamber. 

Normally, we breathe air that contains about 21% oxygen. In hyperbaric therapy (HBOT), the air pressure is increased, allowing your lungs to take in more oxygen than usual. This extra oxygen gets absorbed into your bloodstream and helps your body heal more effectively. 

Hyperbaric therapy (HBOT) is used for a variety of conditions, like helping wounds heal faster, reducing inflammation, or treating certain infections. It works by boosting oxygen levels in your blood, which can improve tissue repair and reduce swelling. People often undergo this therapy to speed up recovery after surgery, for chronic conditions, or even for brain health. 

A research study administered daily treatments to 35 healthy adults aged 64 and older and found HBOT may be beneficial for longevity in two ways.

1. Increasing telomere length

Telomeres are located at the ends of chromosomes and are responsible for maintaining genomic stability. As we age, telomeres naturally shorten during cell replication. 

Shortened telomeres are associated with various diseases, decreased physical performance, and brain atrophy. When telomeres reach a critical length, cells can no longer replicate and either enter cellular senescence or undergo programmed cell death.

2. Decreasing senescent cells

Cellular senescence is a process where cells stop dividing but remain alive and active, releasing chemicals that can cause inflammation and damage nearby cells. This state of cell cycle arrest is often triggered by telomere shortening. Senescent cells accumulate with age and contribute to tissue damage, further accelerating the aging process.

About Heart Rate Variability

Heart rate variability (HRV) is the natural variation in time between your heartbeats, and it’s a measure of how well your body responds to stress and recovers. Greater variability signals better health/recovery.

Heart rate variability (HRV) can be used as a predictor of general health, risk of disease, and mortality. Many wearables, such as the Oura ring, provide the ability to measure heart rate variability (HRV).

Hyperbaric oxygen, heart rate variability & Vagal Tone

Vagal tone refers to how well your vagus nerve is functioning. The vagus nerve helps regulate functions like heart rate and digestion. 

 Higher vagal tone means your body is better at calming down after stress, which is important for overall health. Research indicates that hyperbaric therapy (HBOT) can lead to significant increases in HRV which reflects good vagal tone.

 One study investigated the effects of age and repeated  hyperbaric treatments on vagal tone. The researchers found that vagal activity, as measured by heart rate variability (HRV), increased in both younger and older participants during hyperbaric exposures, with no significant difference in response between the groups.

 This case study investigated the effects of hyperbaric therapy (HBOT) on heart rate variability (HRV) using the Heads Up platform to collect data and track changes.

Method

 

Hyperbaric Oxygen Therapy (HBOT) chamber

The chamber used in this case report was an Oxyhelp dual-plan hard shell chamber.

Protocol

Participant A completed a total of 44 HBOT sessions for a total of 61 hours over a period of 6 months. Participant B completed 97 HBOT sessions for a total of 130 hours over 6 months.

HRV was measured using an Oura ring (generation 3). 

Heart Rate Variability – H.R.V.

Oura is a wearable ring designed to track your health and wellness. It continually collects data on over 20 biometrics that directly impact wellbeing (ex: sleep quality, heart rate, HRV, body temperature, and activity levels). 

 The ring uses sensors to gather data while you’re sleeping or during the day, providing insights into your overall recovery, readiness for activity, and sleep patterns. It is lightweight, comfortable to wear, and water-resistant, making it convenient for daily use without interrupting daily routines.

Data tracking

Heads Up is web and mobile platform designed for analyzing health outcomes.

The platform can integrate data from medical devices (e.g. Dexcom, Libre), wearables (e.g. Oura, Dexcom), conventional lab testing (e.g. Quest, Labcorp), functional diagnostics (e.g. Dutch, Genova, Great Plains), advanced modalities (e.g. hyperbaric oxygen chambers, cryotherapy, infrared sauna) and other sources of health information.

 Analysis tools are provided for both individuals and healthcare professionals to study the effects of health interventions. 

 For this case study, both participants linked their Oura ring to Heads Up and logged all their hyperbaric sessions on their dashboards (Figure 1).

Summary

HBOT is becoming an increasingly popular treatment for general health and wellness. This case study demonstrated how HBOT had positive effects on HRV in two males, ages 48 and 74.  

 HRV is a metric commonly measured and tracked by health enthusiasts. The Oura ring is a useful tool to capture the effects of HBOT on HRV. The Heads Up platform makes it easy to visualize trends collected by wearables like the Oura ring and track changes in HRV.

 Using wearables to measure health benefits can be very motivating for clients undergoing HBOT. Clinics should consider encouraging their HBOT clients to monitor their HRV as a helpful tool for assessing long-term health and longevity.

Using the Oura Ring with your patients

Using the Oura Ring with your patients

The Oura Ring is one of the most accurate wearable devices for tracking biometrics related to sleep, recovery, movement, and overall wellness. To follow are the various steps you and the patient will need to take to add the Oura Ring to your patient’s portal.

Connecting the Oura Ring to the Oura Application

be6e1827 d6dc 4f97 b7ec c793ae79564e

The first thing the patient will need to do once they receive their Oura Ring is download and connect the ring to the Oura application (IOS or Android). Please see Get Started with Oura for step-by-step instructions. 

Connecting Oura Rings to Heads Up Platform

Heads Up pulls the patient’s Oura data from the Oura cloud. The patient’s data is sent to the Oura cloud after the patient first opens the Oura application after awakening.  The Oura ring will sync to the Oura cloud each time it is opened during the day. 

Next, you will need to make sure your patient’s Oura ring is connected to Heads Up. The patient can connect Oura via the Heads Up mobile or web application. 

Once connected, you should see the patient’s Oura ring data on Heads Up. If the Oura ring data is not up to date for any reason, then you should ask the patient to force a manual backup of their Oura ring data to the Oura cloud using the below instructions:

1. Ensure WiFi or cellular data is enabled.

2. Go to the menu Icon_Bars.png on the Home Icon_Home.png tab.

3. Tap Settings Icon_Settings.png.

4. Below Account, tap ‘Back up all data.’

Interpreting the Oura Ring data

Oura rings collect and shares a lot of data. Below are a few of the metrics you should focus on.

Sleep

There is a modern-day misconception about the importance of sleep. We’ve convinced ourselves that anything else is more productive and frequently hear the expression “you can sleep when you’re dead.” 

Recently though, sleep science has been gathering steam and proving what should have been intuitive all along: that our bodies didn’t evolve to waste time. Sleep is central to health and performance. Although we remember little from our time asleep, our brains are firing and our bodies are actively repairing. During sleep, the brain consolidates memories and removes toxins, while the body stokes the immune system and regulates metabolism. 

The sleep hygiene movement is starting to have a social impact and people are waking up to the importance of investing in sleep. If you want to take better care of yourself, start by making your sleep a priority.

The research is clear that adults should get 7 to 9 hours of sleep per night. This range of sleep hours is based on years of research and is the standard set by the National Sleep Foundation. It’s been determined that chronic sleep deprivation can lead to a dramatic increase in the risk of cardiovascular disease and lead to weight gain, in addition to other health issues. 

Another important aspect of sleep that can help maintain optimal health and performance is sleep consistency. Ensuring consistency in your bedtime and waking time can make a world of difference. For example, going to bed early and waking up early during workdays can help improve productivity throughout the week.

Some individuals will wake up tired despite sleeping the appropriate number of hours due to restless sleep. Sleep Disturbances caused by wake-ups, get-ups, and restless time during your sleep can have a big impact on sleep quality and daytime cognitive performance. Restless sleep is less restorative than uninterrupted sleep and it is usually the cause of daytime sleepiness. 

Disturbances can be caused by various factors, such as stress, noise, partners, pets, or different foods. Here are a few tips to improve your chances of getting restful sleep: 

  • Optimize your sleep environment by making sure your mattress is comfortable and your bedroom is cool (~ 65℉/18℃), quiet, and dark. 
  • Avoid spicy, heavy meals, and alcohol close to bedtime. 
  • Avoid caffeine prior to bedtime and late in the afternoons. 
  • While regular physical activity can make your sleep more restful, try to avoid exercising at least 1-2 hrs before your normal bedtime. 
  • Help your brain and body to wind down by disconnecting from bright screens and dimming bright lights 1-2 hrs before going to sleep.

Recovery

From a circadian biology perspective, your day begins when you go to sleep each evening. Sleep allows the human body to recover from the physical and mental demands of the day. There are a number of metrics related to recovery, such as Resting Heart Rate (RHR) and Heart Rate Variability (HRV).

Resting Heart Rate captures the number of times your heart beats per minute while at rest. An abnormally high or low resting heart rate may mean you’re overly stressed and not getting enough rest, or perhaps your immune system is fighting something. 

Heart Rate Variability refers to the constant variation in milliseconds between your heartbeats. As popular as the metaphor may be, a healthy heart doesn’t beat as regularly as a metronome—it changes its rhythm with each beat. Some situations increase variation (high HRV), while others cause the intervals between beats to remain constant (low HRV). 

You may be unaware of these subtle variations, but they reflect your heart’s ability to respond to different situations. HRV can react to stress and/or illness before resting heart rate (RHR), which makes it one of your body’s most powerful signals—providing useful insights into your stress levels, recovery status, and general well-being. As a rule of thumb, high HRV is associated with rest-and-digest, general fitness, and good recovery, while low HRV is associated with fight-or-flight, stress, illness, or overtraining.

While individual days may be lower after high-intensity exercise, a night out, or a stressful day, if your recent HRV is on par with or better than your average, it’s a sign of good recovery. Monitoring HRV trends with an Oura Ring shows whether you are adapting or not to the “load” you are exposed to. This load could be new medications or treatment plans, or an increase in training load. 

Body Temperature

Body temperature is a key signal, as your body constantly generates and sheds heat to hover around your ideal temperature. This metric can act as a warning, signaling cold or broader health development like hormonal fluctuations. Very few wearables track this metric. One exception is the Oura Ring, which monitors your skin temperature while you sleep. This form of measurement is very close to your core temperature only while you are sleeping. You can also use one of the many digital thermometers to check your temperature right after you get out of bed. 

Movement 

Sitting is considered by many to be the new smoking due to the rising evidence that prolonged sitting can contribute to a range of diseases and conditions including: 

  • Cardiovascular disease 
  • Type 2 Diabetes 
  • Anxiety and depression 
  • Obesity
  • Elevated blood pressure 
  • Higher cholesterol 

The human body performs better with regular movement throughout the day. Even standing up once every hour and stretching or doing a few jumping jacks can bring enormous health benefits.

Hacking Your Health with Heads Up: How Alcohol Impacts HRV and Oura Sleep Scores

Hacking Your Health with Heads Up: How Alcohol Impacts HRV and Oura Sleep Scores

Many people often forget that their everyday lifestyle choices can impact their overall health. Daily choices we make in life about food, alcohol, exercise and stress management  — they all add up to inform our health in one way or another.

Of course, you don’t need to be 100% perfect. (Who is?)

But with Heads Up, you can quantify just how your lifestyle choices are affecting you. You can then begin to take action on your lifestyle data, make adjustments as needed to steer your ship back on-course so you can optimize your health. 

For example, when TJ Anderson, health hacker and author of The Art of Health Hacking, attended this past weekend’s Metabolic Health Conference in Long Beach, CA, he used Heads Up’s Analyzer graphing feature to see how alcohol impacted his HRV, Oura sleep and readiness scores. 

A Picture is Worth a Thousand Words

It’s easy to see from TJ’s graph that alcohol consumption had an inverse relationship to his HRV and readiness score. Once his drinks went down to zero, his HRV and Oura scores shot back up again.⠀

Try the Analyzer yourself with the numbers you care about. Whether it’s your HRV, readiness and sleep scores synced automatically via the Oura ring or how many glasses of wine or beer imbibed (entered manually), you can make actionable insights to hack your health. 

How to Use the Analyzer to Track What Matters to You:

  1. Choose Analyzer to bring up the graphing feature within your Heads Up web app
  2. Search the markers you want to trend (e.g., HRV and AM Readiness via Oura, Alcohol Intake), up to six markers if you want!
  3. Choose a time horizon you want to track (e.g., “Last 7 Days”, “This month”, “This year”, or custom dates of your own choosing).

Note: Click the ‘Connect Data’ button to connect to Devices and Apps such as Oura, Keto-Mojo, Biostrap, MyFitnessPal and/or medical records.
