Working on a new analysis type, recording HR and accelerometer data all day/night using Vagis ring. Associating these two metrics in a long term basis yields interesting metrics regarding energy expenditure and reserves.

This is next level from Vagis ring. Sleep recording. Top graph is Vagis Autonomic Variability Index, bottom is Oxyring SpO2. 4 REM stages on both. At 2200 and 0300 Vagis captures variability Oxyring SpO2 cannot detect. Most likely Respiratory Effort-Related Arousal (UARS).

You're alone at home and having a heart attack. You have just 10-15 seconds to save your life. Here's what you must do immediately!

Comparing Vagis ring HR during awake, breath hold, standing, and light movement to the industry standard Polar H10. Took me a few days to build the algorithm from scratch to get HR from the Red/IR channel but it was worth it. Daytime mode will track HR/HRV/Spo2/PWA metrics.

Rick Rubin has low heart rate variability.
So he looked up everything that raises it, picked one technique, and started doing it every day.
It worked.
The technique: coherence breathing. 10 to 20 minutes a day, at least once, sometimes twice.
Now he and @hubermanlab do it together on camera so you can follow along:

My sleep last night. The full sleep Hilbert transform and vascular endothelial analysis which is my favourite, can see phasic/tonic REM substage. The ability to quantify deep sleep VLF thermo oscillation is gold. @DrRyanC @tessfalor

I woke up tired today and had to come home from work. First thing in the morning I did a stand test with the new app I am working on, data from a ring, app, and built in AI agent to discuss your results. My normal resting HR is 65.

Building a new app for remote assessment of autonomic system including sleep disordered breathing. Modes will be breathwork, sleep, active stand. Will also be ANS questionnaire and DNA upload. User will discuss their data with AI agent. Combined data is powerful.

Many patients spend years treating #MCAS, #EBV, or chronic #inflammation.
The immune system doesn’t operate alone.
It’s regulated by the brain and autonomic nervous system.
If that's dysregulated, the immune system can become hypersensitive.
Sometimes the question is:
What is the brain doing?

The biggest needle mover for me has been finding 10 mins everyday to move out of sympathetic overdrive into parasympathetic paradise.
Easiest place to start?
4 sec inhale.
6 sec exhale.
10 min a day.
Just you, your breath & the present moment.
Don’t underestimate this.

What's a skill that takes only 2 to 4 weeks to learn but could genuinely change your life?

Ozempic and GLP-1 cause weight loss via the vagus nerve. In people whose vagus nerve was surgically cut (below the diaphragm, not in the neck), GLP-1 did not reduce food intake or accelerate metabolism. These drugs work through the vagus, in ways we still do not fully understand.

At least 70% of patients with #LongCOVID have autonomic dysfunction The study is examining dysautonomia, not organ damage - a different topic entirely. #dysautonomia is a key feature of many disorders that involve fatigue and functional impairment. My paper on dysautonomia explains it all.

The dive reflex is an autonomic reflex activated by water on the face and/or breath holding. As seen in this breath hold, peripheral vasoconstriction (VLF) increases while HR decreases. Reflex action to preserve blood flow to brain. @ReflexDAO

HRV Spectrum, real-time VLF/LF/HF percent, and HR during active stand test from seated position. Expected increase in VLF and HR with decrease in HF from the position change. What would this data look like in POTS? ME/CFS? @ReflexDAO

HRV Spectrum, real-time VLF/LF/HF band power and HR during transition from free breathing to resonance breathing at 6/min. Upon entrainment, most power found at 0.1 Hz. IBI derived HR shows dramatic RSA oscillation. @ReflexDAO @BreathingByEd
