Today, I want to introduce you to something called heart rate variability (HRV).
HRV is a measurement of the variations between the heartbeats. There are different time distances between your heartbeats.
The more varied the timing is between the heartbeats, the healthier a person is, and the higher the HRV is. The less varied the timing is, the less healthy the person is, and the lower the HRV is.
HRV measures the autonomic nervous system. It has been well-researched and can help a person understand their ability to adapt to and recover from stress.
Many people use this technology to determine whether or not their body can handle the stress of working out on a given day. Maybe they can handle doing high-intensity training one day, but their body would do better with a day off or with low-impact exercise the next.
There are many different lifestyle changes you can make to help improve your overall health. HRV technology can help give you feedback to see if what you’re doing is actually benefiting you. It can even tell you your biological age and rate of aging.
You really can’t take your health to the next level if you can’t measure it. This is a fantastic and easy-to-use tool to help you do that right at home.

Amazing Dr Berg. Your "cookies" must be tracking my recent searches as I've been searching for more information on HRV lately and how to improve it, as my readings since getting my Apple watch in Feb 2021 have chronically been well below where I understand they should be for my age (62), despite 3 sessions pw of both strength training & HIIT cardio (Vo2 max = 40). Only over the last week or so I've heard that poor breathing (shallow with fast exhale) can signal to the body that we are in "flight or fight" mode", ie, stressed, so I've started practicing controlling my breathing to a 4 second exhale (when I can remember). Some Welltory app (highly focussed on HRV) Stress markers have improved, so I'm waiting to see if I can maintain this whether the HRV will start to improve too. Look forward to further videos from you on this topic. Thank you.

If you have a suitable Chest Strap for training, such as a Polar or a Garmin which are both ECG based in effect, then those are compatible with the free Elite HRV App, which is pretty good and very well respected. Thus, you may already have what you need to check your HRV as often as you wish. Also worth mentioning that if you have an irregular heart rate, for what ever reason, then Optical Sensors that measure your Pulse at finger tips, tend to have a hard time counting beats, so are often widely inaccurate compared to an ECG based unit that measures your Heart Rate in terms of R to R interval on an ECG Waveform. Also worth mentioning that your Pulse measured at your extremities, and your actual Heart Rate that the heart is beating at, may not be the same. There can be a deficit between the two, depending upon how your heart is functioning.

I have a background in cardiac, so know about sinus-arrhythmia from way back, now referred to as HRV. I got an iWatch almost 4-years ago and started to track HRV. Sure enough as I trained I saw a satisfying up tick in HRV. Then over the past year it increased further, good tight? No. When I looked deeper, HRV was chaotic (inter hour activity) further examination revealed occasional PVCs (missed or premature heart beats) My message is high HRV doesn’t always mean better.

[@markokitzing4291]

The reason why "suddenly" everyone is talking about HRV is that it is now possible for everyone to measure and access it without such weird devices as mentioned in the video description. A lot of Garmin watches measure your HRV, Whoop has a dedicated device for this, I am sure other vendors provide similar functionality. They do this during the night, while you sleep. No need to put your finger into this thing for a couple of minutes.

Hello Dr. Berg, I have a thyroid, damaged by Monsanto's 'Roundup' which I was accidentally sprayed with. This has also given me a goiter. Do you know of any method/substance that can help repair/rectify this problem please. I was prescribed Levothyroxine, but am allergic to all three versions, especially the two earliest. The most recent version did no good, as each time I increased the dose, my body was fooled into reducing its own natural production. Eventually I was on 150 micrograms per day, and then got an allergic reaction. I stopped for week, and then started again on 25 micrograms per day, and still got an immediate allergic reaction. I take kelp powder for additional iodine, and brazils for selenium. I would be pleased with anything you can suggest.

You canj't read HRV from a finger. It is Pulse Rate Variability. HRV requires a true electrocardiogram on the chest. Like a Polar H10 chest strap or a lab grade multi-lead monitor. Yes, PRV can approximate HRV for healthy and good blood circulation health people, but it can also be a lot off. How do you know? You don't.

I think this might help you identify first where the problem is - is it too much SNS or not enough PNS. Ever since I went through basic training - no matter what I would get up at 4 am. Being rudely awakened at 4 created a dent into my circadian rhythms. REM sleep is more controlled by SNS - so, this tool may provide feedback to try a bunch of different things and see what moves the needle.

That would be a portable ECG (in the USA its EKG), or Holter, but it may advise HRV, depending upon the Software that it is used with. Or, put another way, its Data will also cover HRV, but may not show this on the results if the Software does not analyse that. ECGs are primarily intended to log the electrical activity of the heart from various perspectives. The portable one is to try and capture events that might otherwise be missed from a shorter ECG carried out in Hospital or by a Doctor, which may only be for 30 seconds. So those ECGs can miss events that come and go, which the 24 hour ECG may catch.
