I've been reading about this device (an in the ear device that measures blood flow) for a while. The company has a new name, Lumia health.

I don't normally share product website links but this device (still in the early stages) has me intrigued:

Is anyone out there using this device? Or have other information about it? Thanks!

Last Laughs
Can you die from laughter?
Is there any truth to the phrase "I'm dying of laughter"?

What causes fainting? Scientists finally have an answer
Mouse experiments reveal the brain–heart connections that cause us to lose consciousness rapidly — and wake up moments later.

Jonny Lovelace, Jingrui Ma, ... and Vinny Augustine discovered the vagal pathway underlying fainting, really exciting work, summarized here: https://www.nature.com/articles/d41586-023-03450-3 , full paper here: https://www.nature.com/articles/s41586-023-06680-7 (I helped a little w/ neural analyses)

When the mouse faints, its eyes roll back and most neurons across the brain *shut off completely* (at yellow line in first figure, shows one example #neuropixels recording). But neurons in the hypothalamic PVZ increased their firing during this time period (first group in the second figure). These neurons were causally implicated: inhibition increased fainting duration while excitation increased arousal.

Nearly 40 percent of people experience #syncope, or fainting spells, at least once in their lives. These brief losses of #consciousness, whether brought by pain, fear, heat, #hyperventilation or other causes, account for a significant portion of hospital emergency room visits.

Fainting: When to get an evaluation: Best Of - WBZ Radio -0191
If you experience fainting, when should you get a formal evaluation. Dr. Mark Linzer, formerly of Tufts Med and now at UMinnesota tells Dr. Smith the indications that are worrisome.

Fainting: It’s Causes and Symptoms: Best Of - WBZ Radio -0191 Dr. Smith talks with Mark Linzer, MD formerly of the New England Medical Center and currently professor of medicine at the University of Minnesota. Fainting is also known as syncope and is driven by the vasovagal reaction. #linzer #fainting #syncope #vasovagal #wbznewsradio https://www.instagram.com/p/CyPvR7uOCTe/

Afraid of needles? You're not alone! Approximately 16% of adults avoid getting a flu shot because of a fear of blood or needles. #SFU Biomedical Physiology and Kinesiology professor Victoria Claydon has been researching ways to help reduce the stress: https://www.sfu.ca/sfunews/stories/2023/09/fainting-from-needles-may-be-alleviated-by-reducing-pain---study.html #sfubpk #SFUScience #syncope #vaccinations #flu #flushot

If you suffer from micturition syncope, you faint when you pee and have a lot of extra cleaning to do.

@paul Thanks for that tip Paul. I just had my first episodes of #syncope at age 63 due to #hEDS. I believe that this was a problem when I was in school and university but hadn't dealt with it since. I believe my issue is related to being dehydrated. So much to learn!

brain fog makes it hard to remember all the things that can make POTS worse

I wrote a guide to things that can flare POTS-related dizziness, so you only have to remember four basic categories

#POTS
#NEISvoid
#Dizziness
#Syncope
#LongCovid
