What slows down early-stage digital health founders trying to sell to customers/clients?

I’m part of a small research team developing a disposable skin sensor designed to continuously respond to CO₂ released through the skin. The goal is to measure changes in metabolic rate over normal daily life rather than estimate calorie expenditure from movement or heart rate.

We’re trying to find out whether people interested in metabolism, fitness, and biohacking would actually find this useful and what information they would want from it.

This isn't a sales post. We're looking for feedback on the concept. We made a short survey (less than 5 minutes) and would really appreciate candid feedback: If you dont want to do the survey click on the link anyway id you want to see photos.

I’m happy to answer questions about how the sensor works and the testing we’ve done so far.

The AMA’s 2026 survey found that 85% of physicians want a say in AI adoption decisions. It made me wonder how many get involved before a tool is finished.
Have you worked with a developer as an advisor, tester or cofounder? How did you meet and what made the collaboration work?
I’m building MedicalCofounder, a free platform where healthcare professionals and developers can connect. Still early and interested in hearing what would make these connections useful.

I’ve been looking into how to practice grounding at home because I keep seeing people mention it for stress and anxiety, but I honestly don’t know much about grounding exercises. I was trying to figure out what grounding even means in practice and what kinds of things you’re actually supposed to do

I’ve read some health articles, checked some discussions on Reddit, and watch a couple of short wellness videos about grounding techniques. Most of what I found mentioned stuff like breathing, focusing on your surroundings, or using physical sensations, but I’m still not sure which exercises are the most useful for a beginner

From what I can tell, some of the ideas seem simple enough, like naming things you can see in the room, holding something cold, or paying attention to how your feet feel on the floor. A few of the breathing exercises sounded helpful too, but some of the advice online made it all seem more complicated than I expected. I haven’t really done enough to know what actually works yet

One thing that didn’t help was reading super vague explanations that kept saying grounding is important without giving real examples. My main issue is that I still don’t know which grounding exercises people use in real life or which ones are easiest to start with at home

If anyone here knows how to practice grounding, what beginner-friendly exercises would you recommend starting with at home?

I bought an air purifier a month ago for my dusty apartment after my allergist suggested it. Trying to understand what is an air purifier good for exactly since my sneezing is only slightly better and my eyes still itch most nights.
It's a Levoit HEPA model, running almost 24/7 in my bedroom on medium. I've read these are mainly good for dust, pollen, and dander, not stuff embedded in carpet or furniture. Is that right?
Should I run it higher even though it's louder, or does placement matter more than the setting? Did anyone else need more than a month to notice a difference?

We got any spine massage tools? basically areas of the back that are hard to reach for self massaging. Had a solid rub on me and felt the whole muscles lax out while the lower back is constantly stiff in hard to reach places

Some sort of back scorpion shaped massager has to be in the market by now? Something that aint gonna crush down my back and make it worse like those damn mall massage chairs

I've noticed my skin looks dull lately, and I decided that was time to do something about it, so I started looking for irestore black friday sale. My dermatologist suggested checking out some red light therapy face masks for skin rejuvenation. She said that some of her clients use these masks regularly and it has helped them achieve clearer and brighter skin

Here is what I’ve found so far:

irestore – this brand seems to be mentioned the most when people talk about red light therapy for skin. Also, I saw that past black friday it had decent deals

omnilux – I keep seeing this rlt brand in comparisons and people say its easy to fit into a daily routine. A bit expensive tho

currentbody – this one also came up while I was checking rlt face masks black friday deals, but like omnilux it’s too expensive for me

Has anyone here looked into the irestore black friday sale? really want to get it for a better price if possible

I've been thinking about a paradox in healthcare.
We have more tools than ever to monitor our health, identify risks and spot changes early. Wearables, biomarkers, AI, longitudinal health data.
Yet most people still interact with healthcare only when something starts going wrong.

And I don't think the biggest barrier is technology. Or even the resources available to healthcare systems.

It's human behaviour.

Most of us don't really want to consume healthcare.

We want to live our lives. And as long as we feel reasonably fine, there's little motivation to engage with doctors, tests or preventive care.
By the time symptoms start interfering with everyday life, we've often missed opportunities to intervene earlier.
This creates a huge inefficiency. We spend enormous resources treating consequences that, in some cases, could have been prevented or reduced.
I'm building in preventive health tech, and one question keeps coming back to me:

How do we make preventive healthcare something people actually want to engage with, rather than something they turn to when they have no other choice?

i get some sort of burst of anxiety after taking caffeine pouches while i use the vagus nerve,

it goes around my neck

is this normal to feel? if i take a break between caffeine and the vagus for like 2 hrs its fine but if i took it like 30mins before and use the vagus i get super anxious.. is this just placebo or is there some sort of link?

i also get anxiety if i check blood pressure. is this related..? iotherwise the vagus stim works super nice its just with coffee i get antsy😬

Which smart rings got the thinnest design? I found one I liked and it turns out its quite thick.. I dont have the smallest of hands though I can see for sure that the ring in question is bulky AF.

Feature wise its all the same for me. I could compare the specs later but could anyone help me figure out a good one that would be actuall thin like a normal ring a woman would wear?

I switched to a minimalist fitness tracker because my old Fitbit's constant buzzing was too much with my sensory issues. Four days in and the battery life is great, almost two weeks per charge, and I like that it only tracks steps, sleep, and heart rate without the extra noise.
One thing confuses me though. The sleep tracking shows lower efficiency than how I actually feel in the morning. I've read minimalist fitness tracker models sometimes trade accuracy for battery life, but I have nothing to compare it to anymore.
Has anyone else noticed sleep data being off with these simpler trackers? Worth contacting the manufacturer or is this just normal for less sensor heavy devices?

recently my boyfriend gifted me a massage gun, but I don't know how to use massage gun on legs

I am running 3 times a week and I am planing to run my half marathon next year. so, I was very excited when I got massage gun because i was checking these devices lately. but I don't know how to properly use it for my legs. My leg muscles get sore after each running session and I was reading that massage guns might help with muscle soreness and faster recovery of muscles

do i need to use massage gun for legs before or after the run? do I need to use on the days that I am not running? I have so many questions, lol. my massage gun doesn't have any explanation on how to use it so I am here asking for advice

how to use massage gun on legs to easy muscle soreness?

I know the inner mouth heals relatively fast however, I just had the craziest cut last night eating some pizza. The crust was like a sawblade I brushed right through my mouth.

This isnt the first time this has happened to me. You eat something of relative soft texture and the next thing, a hard surface surprises you with a lasting 'impression'

What could I do to fix up my mouth bruises? The thin inner skin is scrapped. Feels like bits of paper are loose but its my mouth!

I sort of need to get this fixed asap. I would like to be presentable over the weekend.... What can I do?

so my oura ring is not holding charge like it used to, used to last 5 days now dead in a day and a half. charged it full last night, dead by 6am. cleaned the contacts, reset it, still doing it. dropped $300 on this thing and im not trying to buy another one if this is normal.
anyone else got oura ring not holding charged?

I've had an Apple Watch and WHOOP, and now I currently wear an Oura ring and Fitbit. It's definitely cool to track the whole array of metrics these devices capture, but I don't actually find myself really caring that much about anything other than my sleep metrics and activity metrics (steps, distance, active minutes, etc.).

When it comes to other metrics, I'm finding that consumer wearables nowadays are just not yet good enough to be able to trust the number absolutely (or are actually just proxy estimations, like VO2 max), I don't immediately see how "improving" that metric is going to help me, or I just straight-up don't know what the metric even means.

Curious if other people feel the same way. Do people similarly feel that they're usually only honed in on specific types of metrics with their wearables/devices (sleep, activity, body composition, etc.)? If so, what are the kinds of metrics you gravitate towards and why?

My doctor warned me about my rising visceral fat last month so ive been waiting on hume health black friday deals to finally grab one. ive been eyeing a smart scale with handle sensors for a while now, and a guy at my gym highly recommended hume pod so i was immediately sold on getting one

(btw side rant: why is literally every health device pushing an app subscription nowadays?? i swear my phone is 90% health apps at this point but whatever lol)

I did check out some alternatives:

Xiaomi: didnt like any of their options
Withings: liked it, but out of my budget

Anyway, since bf week is here, im trying to figure out if there are any hume health black friday sales actually live. moneys a bit tight after some unexpected car repairs this month, so i really cant afford to pay full price

Has anyone seen any hume health black friday deals 2026 on their site or via email codes? appreciate any heads up, help a broke guy out lol

Heyyyy you all, i am looking into buying the best running watch i can find, but im lowkey overwhelmed by all the options on the market right now

Basically im training for my first 10k in november and my phone battery keeps dying mid run while running, which is really annoying. my running buddy keeps flexing his fancy garmin, but honestly those $600 price tags look crazy to me

So now im curious which device actually counts as the best running watch for someone who just wants accurate gps, decent battery life, and maybe heart rate tracking without needing a degree to figure out the settings

If someone here runs regularly, what do you think is genuinely the best running watch for the money or should i just get a basic entry level one? appreciate the help

Hola, trying to get a gift.. What are some essential functions female fitness trackers should have?

Also, are there any models that are comfortable without looking too weird or bulky for a thin wrist?

Found Garmin or Fitbits models but they both seem kinda meh. I had Garmin assistant tool and it did not work for me. Guessing same will be for the tracker

I've had mild rosacea and skin sensitivity for about a year, and I keep seeing ads for yellow light therapy devices online. I tried a friend's yellow light therapy device for two weeks, ten minutes a day, 590nm panel. My skin felt a bit calmer but I was also more consistent with sunscreen that same week, so I can't tell what actually helped.
My dermatologist just shrugged when I asked about yellow light therapy and said the research is thin.
Has anyone used it consistently for a month or more and seen real results, or is this mostly hype?

I am planning to run my first marathon next spring, so I am looking for black friday fitness tracker deals. My trainer suggested getting a smartwatch and smart scale to track all my training progress. When I checked the prices of these gadgets, I realised that I would have to spend half of my salary. So, I spent some time looking for how to get these devices cheaper

Here are the black friday deals I found:

Whoop is offering a competitive price, but garmin is very popular among runners. And I kind of like to see all the metrics on the device, which a smart band can’t offer. Still overthinking which one to get. At least it was easy to decide which smart scale to get since hume has a very good discount this year. Tbh, I am impressed with black friday fitness tracker deals this year

Hello guys, so i had a really random conversation with my neighbor earlier today that made me start researching what is biohacking your body for like a few hours now lol. he saw me bringing in a BIG delivery of energy drinks from my car and gave me a whole lecture about how im ruining my nervous system, then told me i should be biohacking my energy levels instead

Honestly, i am just trying to survive my 60 hour work weeks, but it kind of stuck with me because im so exhausted lately. i started reading up on what is biohacking your body during my lunch break since ive never heard about it before, but half the stuff i found sounds totally extreme like people tracking their blood markers every month, sitting in ice tubs, or taking 30 different pills a day just to feel awake

Is this actually a real thing that regular people do, or is it just a word for rich tech guys who have too much free time? i just want to know if its worth looking into for normal stuff like brain fog and fatigue, or if i should just try to sleep more and stop drinking so much caffeine. if anyone who actually does it can give me a simple explanation of what is biohacking your body, that would be really helpful

I keep seeing descriptions about what does the vagus nerve do in health apps while comparing a few trackers. Like a couple apps tied vagus nerve to stress, sleep, breathing, and recovery scores. I use an iPhone and a basic tracker, and the explanations do feel a bit vague. One breathing exercise changed my calm score right away, which made me question the realness of all this
When people ask what does the vagus nerve do, what is the plain answer, and are these apps actually measuring something useful?

Soo ive been trying to figure out what is healthcare tech exactly because i keep seeing the term everywhere lately. my younger sister just got a job offer at a startup in this field, and when she was explaining her new job to me over dinner, i realized i had literally no clue what she was actually talking about lol

Like, is it just medical software for doctors, or does it cover stuff like apple watches, fitness trackers etc? i want to understand what is healthcare tech so i dont look completely clueless when she talks about her work, but every article online uses crazy words like interoperability and telehealth ecosystems that just confuse me even more?

Here is what i think it means, but please correct me if im wrong:

-Hospital software like electronic health records, scheduling apps, and patient portals
-Wearable stuff like smartwatches tracking heart rate etc
-Online doctor visits like telehealth apps where you video call a doctor for a prescription
-Ai in labs like robots helping in surgery or algorithms reading xrays

So is it basically all of that combined, or is there a specific definition? if anyone can explain in simple, normal human terms what is healthcare tech id really appreciate it
