Does anyone have advice about HRV specifically within the context of anxiety?
I've been measuring my SDNN using a Polar strap, and it hasn't really budged. However, I'm not taking that too seriously. I think my HRV is already fairly good because I bike. Anecdotally, I think the coherent breathing helps, especially if I _remember to do it in stressful moments_, not just in the morning.
> The selective impact of prolonged exhalation breathing on reward responsiveness has important implications for clinical contexts, such as anxiety, panic disorder, and depression, given their distinct autonomic signatures and maladaptive reward processing. By enhancing cardiac parasympathetic modulation through prolonged exhalation techniques, individuals may restore reward processing, a valuable pathway for emotional recalibration. Prolonged exhalation harbors the potential for a low-cost, low-risk, easily applicable intervention to be incorporated into therapy or rehabilitation programs, especially to support pharmacological treatments.
But I know a base jumper .. and he only does the jumps if he feels the fear and his kick is to overcome it and feel the adrenalin rush.
This sentence has beautifully crystallised the meaning of what it means to be an adrenalin junkie ^_^
“If you feel jealous, talk about it, then we’ll figure something out”
In which one of the children wants the other one’s cool toy so the parent’s response is to encourage them to ask for it to be shared. Except they aren’t siblings and it’s the mom from the other family teaching their own jealous kid to go ask.
How about this?: Back off cat family, you fair weather commies — that’s Daniel’s bubble wand, not yours. At least share some of your own crap before asking for someone else’s:
”If you feel jealous: shut the fuck up, you can’t just have someone else’s stuff nor should you feel entitled to guilt them into sharing it just because you asked nicely.”
Slightly tongue-in-cheek. Slightly.
Tangentially related, are there any wearable devices that allow for high resolution respiration monitoring? I'm imagining some measurement of lung expansion over time (probably at least 10 Hz) so that I can quantify the deepness/shallowness of my breaths as well as the phase of inhalation/exhalation cycles.
Our brains trick us to breath on defaults adjusted to our surroundings.
What I have found working to slow down breath is:
1st willful exercise repetition,
2nd changing surrounding environment and lifestyle (nature, decluttwring, idleness, peaceful eating, proper sleep)
3rd gaining awareness about trigger mechanisms (overcommitments, overexpectations)
It is all self-regulating. And pretty much what mindfulnes, meditation, prayer or forest walk brings.
Common physical reflexes, autonomous responses, and subconscious regulation, are there as aids to us. The fact that they are not universally beneficial is one of the purposes of having higher level control. Not to universally suppress responses, but to notice and cope when they misfire.
It would be interesting to have a map of breathing patterns across a wide variety of situations, to identify the range of situations where prolonged exhalation is adaptive.
My guess, based on the common reflexes of mouth clamping and breath holding before great physical exertion, is that prolonged exhalation is part of an adaptive psychological orchestrator for when we prepare to take on something difficult, risky (but necessary), or that needs a fast strong response.
Our fast acting emotions, and slower acting moods, are similar guides. Patterns of stimulus and response from our baseline physiology and psychological, that we absorb into our higher level operation, as generalized guides for analogous responses to contexts at higher abstraction levels.
With minor maladaptive responses inevitable, if we don't pay attention. And severe maladaptive responses often ingrained as overcompensation for situational or developmental traumas.
Additionally, there's a practice called "walking meditation" [0] that can also be useful to practice this area of skills.
I always thought that was part of their weirdness and maybe even some personality trait that led them to this sort of thing, but knowing it's an active choice makes it even weirder somehow.
Remember to blink!
You say fear is good, presumably because it stops you from doing things you don't know are dangerous.
But then you say you can do a technique to defeat fear when you know the fear is irrational.
But your argument starts from the premise that you don't know a situation is dangerous or not without the fear so how would you know it's irrational?
In my experience it's the opposite, most fear is not useful.
The results are specifically about a breathing that is slower due to prolonged exhalation.
This kind of breathing is one of the many kinds of breathing traditionally practiced in yoga and also in many Asian martial arts, each kind for different purposes.
The experiments used in TFA have used a breathing rhythm of 2-second inhalation with 8-second exhalation, which is about the same as how I learned this kind of breathing as a child, from a yoga manual.
I have never heard about a single breathing of any kind to have much effect. For any kind of breathing rhythm you may need to use it from a large fraction of a minute up to a few minutes to have a noticeable effect.
As explained in TFA, this particular kind of breathing rhythm changes the balance between the 2 components of the autonomic nervous system, in favor of the parasympathetic nervous system.
This has the effect to diminish the influence that fear has on making decisions.
TFA is interesting because it provides a scientific confirmation about the usefulness of this kind of breathing rhythm, which has been traditionally used for centuries, if not even for millennia, in India, China and other Asian countries.
Cant do this for everything but examples are supermarket lists, home viewing (know your price, questions, decision criteria)
mindfulness and meditation have been seeing broad adoption - with apps like headspace etc also getting good traction
