#OpenScience #OpenTeaching community,
yesterday, for the beginning of the exam season, I gave a lecture on stress management. To demo Respiratory Sinus Arrhythmia, I built a little tool to show real-time ECG + heart rate from a Polar H10 in the lecture hall.

Students could see how breathing affects heart rate. The "aha!" moments were amazing : )

It now records and is available as FOSS:

"Patients with #LC under 25 years of age had a lower HRV categorized as a very-low-frequency (VLF) domain (p = 0.012)”

The impact of long COVID on heart rate variability: a cross-sectional study - BMC Infectious Diseases

Background Long-term COVID-19 (LC), which may affect the autonomic nervous system (ANS), is the term for the symptoms that some patients had for an additional month after contracting the virus. Therefore, during the LC phase, ANS status was evaluated in patients with mild-to-moderate COVID-19 using heart rate variability (HRV), a measurement of ANS function. Methods A cross-sectional research with 173 participants - both positive and negative for COVID-19 – was conducted. Based on self-reports, patients with COVID-19 were classified as to whether they had LC or not. A 5-minute ECG recorder and data detection and response report were used to measure the ANS. Results There were notable age differences across the groups (p = 0.034). Patients with LC under 25 years of age had a lower HRV categorized as a very-low-frequency (VLF) domain (p = 0.012). Compared to the group without LC, a higher number of people in the LC group had aberrant autonomic neuroactivity (p = 0.048). Conclusion Mild-to-moderate patients with COVID-19 in young to middle age may develop autonomic dysfunction one month after infection.

Lonely individuals show reduced cardiovascular adaptability under social stress

New research shows that lonely individuals have reduced heart rate variability during social stress, indicating less effective bodily adaptation.

PsyPost
Both sensorimotor and autonomic neuropathy may be common in hypothyroidism, despite treatment

A new study may provide a previously unknown reason for reduced quality of life in treated hypothyroidism (syndrome T). Systematic investigations of persons with treated hypothyroidism revealed unique signs of sensorimotor dysfunction in quantitative sensory testing (QST). Being marked by thermal and mechanical hypersensitivity, the pattern differs from the constellation seen in diabetes and other conditions leading to polyneuropathy. This may explain some of the sensory symptoms of syndrome T. Additionally, the study found reduced heart rate variability (HRV), depending on the titres of thyroid autoantibodies. This observation, indicating possible autonomic neuropathy, could explain the components of syndrome T that affect the circulatory system. Other results of the study included that both anxiety and depression were significantly more expressed in subjects with autoimmune thyroiditis and that they were also associated with antibody titres. The autonomic function significantly correlated with anxiety and depression, too. Additionally, the depression percentiles in the hospital anxiety and depression scale (HADS) were negatively associated with step-up deiodinase activity (SPINA-GD). In a control group with normal thyroid function, both autonomic and sensorimotor function correlated with the thyroid’s secretory capacity (SPINA-GT).

Discovered this really weird thing where #programming is the only activity I can do that puts me in a state of (wakeful) "rest" according to #Garmin's #heartRateVariability measurements (which seem accurate, unlike it's sleep detection).

Not even #meditation achieves the same thing.

I'm pleased I've found something that works, but I can't spend my waking hours programming 😅 What else can I try that might have the same effect? (How can I tweak the meditation to have the same effect?)
