Lightwork was selected to perform home health assessments for clients of Immortals Concierge, Immortals’ premium concierge health program, ensuring member homes are evaluated alongside the rest of their health.
As announced by @bryan_johnson in February, Immortals Concierge includes a dedicated concierge team, BryanAI 24/7, extensive testing, millions of biological data points, continuous tracking, evidence based skin and hair protocols, and access to the best longevity therapies on the market — as well as a Lightwork Home Health assessment.
"Immortals Concierge is an exceptional program, and we're excited to provide assessments to their clients and help them create healthy, optimized home environments," said @andy_bromberg, Co-Founder of Lightwork, “home health is a critical component of overall well-being and longevity. Immortals Concierge follows a philosophy of ‘measurement, scientific research, intervention, repeat,’ and Lightwork aspires to the same approach.”
Lightwork’s home health assessments are comprehensive, white-glove evaluations that can include air quality, water quality, EMF exposure, lighting, mold, noise, chemical exposures, and more, along with remediation support.
Lightwork leverages its custom technology and procedures to quantify these exposures and potential remediations, which are measured against the Lightwork Exposure Index, a proprietary set of science-backed standards.

I'm very bullish on tech that helps reduce ambient stressors, especially one-time changes that help to live in a default healthy environment.
💡 Unfortunately the vast majority of LED bulbs are terrible for your brain (see video below) and even the "warm-looking” LEDs still contain blue-light that keeps you awake at night.
🔌 I've heard stories from students who have been enormously impacted by 'dirty electricity' running through house power lines and being zapped by unobvious background EMFs.
🦠 I've lost count of how many friends have been heavily impacted by prolonged mold exposure (especially in austin where house ventilation is poor)
💨 I was amazed by how much particulate matter was in our house (especially when cooking) so we doubled down on home purifiers.
Long-term I'd prefer to live in a world where the default home environment doesn't silently tank your health... but in the meantime, the ROI on these is absurdly high.

This was my experience working with @lightworkhome when we tested our @eightsleep in our bedroom.
No elevated levels of EMFs in the bed.

EIGHT SLEEP is pretty popular in the wellness world, but we avoided getting one for many years out of concern for “sleeping on an emf”
When I lived in LA, we actually slept on a Faraday cage because of all the Wi-Fi signals so close to our house.
But I finally got an @eightsleep, and of course, as the most publicly measured woman in the world, I tested it.
Here's a video on my findings (I had this professionally tested, my own in-home testing, and it matches the EIGHT SLEEP testing.) Good work @m_franceschetti

Using a HEPA air purifier improved cognitive function by 12% in middle-aged and older adults.
And they only used it for a month!
That's a meaningful improvement in a short amount of time, all from a simple purchase you can make for your home.

I just had my house tested by @lightworkhome and low and behold, like @lennysan... I too was being blasted by EMFs🔌
They did a 4hr+ at home assessment covering air + water quality, mold, EMFs, lighting & household products (you can see my results overview below)
Even though we're renting, making a few changes to create a 'default healthy' home environment feels like such low-hanging fruit because they're mostly one-and-done fixes.
Their estimate was that it'll cost <$250 total to make the main suggested improvements (full-spectrum flicker-free LED, wifi-router cover, plug timer to turn off connected devices at night, shielded extension cords etc.)
I'm so bullish on what @andy_bromberg, @DomFrancks and the team are building with Lightwork. If you're interested in learning more they're generously offering a free home health consult here: lightworkhome.com/nsm
I did a whole-house toxin health assessment, where a guy spent half a day testing our house's air quality, water, EMFs, lighting, mold, and household products.
So many surprises:
- Our Waterdrop reverse-osmosis water filter seems to be introducing a chemical (Dichloromethane) into our drinking water that wasn't in the (whole-house filtered) tap water. Will recheck this to make sure it's not a fluke.
- Even though we have air purifiers in many parts of the home, they weren't on the proper setting so our air quality was not great. Turned them all up higher.
- Most of our light bulbs have blue light and super high flicker rates which disrupt circadian rhythms. Replacing a bunch of them.
- The wifi router in my office is EMF'ing the sh*t out of me. Going to move it to a different part of the room.
- The powerstrip under our bed is EMF'ing the sh*t out of us. Getting a grounded power strip that avoids this.
- Some of our shampoos and soaps had harmful ingredients.
On the plus side, no gas leaks or carbon monoxide 👌
I'm predicting this is going to become the next microplastics-type trend, to test your home for toxins and harmful products.

Thanks to @dhrupurohit for having me on his podcast! We did a DEEP dive conversation into all the ways your home can shape your health ⬇️
For the past year, I’ve been launching & growing the California office for @lightworkhome - where we optimize homes for health.
In that time, we’ve worked with hundreds of clients across the world, been selected to perform home health assessments for Immortals Concierge, and work closely with scientists and clinicians from The WNDR Lab, Atria Health and Research Institute, and many more.
We’re the simplest path to creating a home that is aligned with your biology.
In this podcast, we cover how to:
* Optimize your bedroom for deep & consistent sleep - and your home office for wakefulness.
* Separate what actually matters about mold and EMFs from what's overblown.
* Find the simplest and highest-leverage actions you can take to create a healthy home.
Give it a listen! I’d love to hear your thoughts.
I’m fascinated by all of this stuff and love jamming on it, so I’ll drop a calendar link below - if anyone out there has any questions about your home’s health, shoot me a DM and I’d be happy to chat!

It turns out, my house has been making me dumb(er). Sorry about that. Fixing it now.
After I saw Lenny's tweet a month or so ago, I did a home health assessment and here’s what I found:
- High CO2 levels (~1,000 ppm) due to lack of ventilation. Studies correlate CO2 at this level with impaired cognitive function. Fix is simply opening windows.
- High levels of small particulate matter (PM0.3 - PM1.0) in the home compared to outside. Air purifiers are the move here.
- LEDs impacting sleep. We swapped out bedroom LEDs for incandescents.
- We had WiFi Access repeaters throughout the house. RF levels were high. Still learning about EMF effects but out of precaution took out the repeaters next to where we spend a lot of time (e.g. the kitchen).
- Luckily, very low levels of mold!

Testing was done with @lightworkhome. Easy and positive experience overall - turned a ton of research and small decisions into just trusting their work. I do think investing in the health of the environments we spend time in is a no brainer, like investing in better mattresses etc is. I can't afford to lose any more brainpower than I already have.
We're fully operational across Europe (as well as the US and Canada)!
We built a free, data-driven tool to objectively help you choose the right air purifier for your home.
There is so much marketing noise in the air purifier space. Companies use and come up with all sorts of buzzwords to suggest that their purifier does something special. It's shockingly difficult to get straight answers and objectively evaluate performance.
So we created a free tool to help you pick the right air purifiers for your home. 100% free, no signup required, no affiliate links, no partnerships or bias. Just data.
Here’s something that might surprise you: most modern air purifiers filter about the same percentage of particles. Any HEPA filter removes at least 99.97% of particles at around the size it performs worst at (which is pretty dang good!). So what matters more is throughput (measured as CADR, or Clean Air Delivery Rate), how much air the unit can push through that filter. A purifier that's too small for your room will never get the air clean, no matter how good the filter is.
But after consulting on air filtration with a lot of clients, we've realized that there are some other real-world, practical considerations that most recommendations ignore:
> Quiet matters. If an air purifier is too loud, people simply won't use it. And an unused air purifier is no good at all.
> Ease matters. If you have to replace the filters too often, most people will simply not do it. And dirty filters tank the efficacy of a unit.
> Beauty matters. For many customers, having an ugly air purifier is a non-starter. So finding aesthetically-appealing ones, at least for certain rooms, is a factor.
> Price matters. On top of all that, people want value. If it's too expensive, it won't get purchased in the first place.
So we've created a tool that factors in all of the above to recommend the right air purifiers for your home. You put in your room sizes and preferences around noise and design, and it recommends a best-value pick and an upgrade pick for each room. The site walks through the methodology behind it all, including a metric we developed called "Quiet CADR," the clean air delivery rate at a volume you can actually live with.
One of our main goals at Lightwork is to bring science-backed, data-driven rigor to the home health industry, which has historically been plagued with imprecision, poorly-supported claims, and (at worst) scams.

Try this at your home!
Your Lights might be Flickering And You Don’t Even Know It. This could be massively disrupting your nervous system.
Alexa at @lightworkhome brought this to my attention when she gave my home a full diagnostic test for mold, dirty energy and a bunch of other toxins.
Try putting your phone on slow motion and poining it at your lights.
You may not see it with your eyes, but your brain is still processing it.
Over time, low quality LED and fluorescent lights can contribute to:
• Eye strain
• Headaches
• Fatigue
• Brain fog
• stress on your nervous system
The biggest offenders is Cheap LEDs and Fluorescent bulbs.
Some Better options are:
• flicker-free LEDs (CRI 90+)
• Warm light (2700K) in the evening
• Incandescent or halogen if possible
Your environment affects your performance.
This small adjustment in your home and workplace might make a huge difference in you life. 💡

🚨NEW: Experts in environmental exposures from @lightworkhome actually went on-site this month to take measurements of the EMF levels around the 49ers practice facility and Levi's Stadium. Some of the findings they discovered and sent me are alarming.
Their findings:
> Near the transmission lines around the perimeter of the facility, we measured 4.7 to 22 mG, roughly 5 to 20x higher than typical residential environments.
> Further from the lines, we measured 0.3 to 1 mG, which is typical for most towns and cities.
> We were unable to access the facility itself, so indoor levels remain unknown.
> Strong evidence across multiple meta-analyses links continuous exposure above ~3 mG with increased childhood leukemia risk, and that threshold is exceeded in many areas surrounding the facility.
> Firm conclusions cannot be drawn without readings from inside the facility, but unusually elevated exposure alongside an atypical injury pattern warrants further investigation.
#49ers
The internet has lit up with discussion about whether elevated electromagnetic fields near the 49ers’ practice facility could be contributing to the team’s spate of injuries. Lightwork Home Health visited the area to measure the Extremely Low Frequency Magnetic Field strength, or ELF-MF.
Our findings:
> Near the transmission lines around the perimeter of the facility, we measured 4.7 to 22 mG, roughly 5 to 20x higher than typical residential environments.
> Further from the lines, we measured 0.3 to 1 mG, which is typical for most towns and cities.
> We were unable to access the facility itself, so indoor levels remain unknown.
Strong evidence across multiple meta-analyses links continuous exposure above ~3 mG with increased childhood leukemia risk, and that threshold is exceeded in many areas surrounding the facility.
Firm conclusions cannot be drawn without readings from inside the facility, but unusually elevated exposure alongside an atypical injury pattern warrants further investigation.
We recommend an advanced on-site assessment that maps field strength, calculates time-weighted exposure based on usage patterns, and measures temporal variation as power demands cycle. If needed, remediation can range from simple usage changes to engineered options such as active shielding.
Lightwork Home Health would be happy to offer a preliminary evaluation of the facility pro bono to ensure our 49ers' training environment is setting them up for success.
We tested @awilkinson's house. He's as health-conscious as they come (and his house was top tier). But we still found room for improvement.
In his recap, he said:
"I've talked to a bunch of friends about this. The ones who've gotten their homes tested all have the same thought: 'It's insane that nobody checks this stuff.'"
