All Deep Dives

The following is an excerpt from Andrew Wilkinson's newsletter, Never Enough, where he wrote about his experience getting a Lightwork Home Health assessment.

Mine was.
Here's how I discovered the issue…
My friend Justin Mares is a complete health nut. He's the brains behind companies like Kettle & Fire, TrueMed, and Perfect Keto.
Whenever Justin tells me about some new health concern, I usually roll my eyes and joke about tin foil hats.
He's a good sport and takes it in stride—but within a few years I'm often eating humble pie. He's usually right.
He's an obsessive reader of science and always a few years ahead.
Recently, he told me about his new company, Lightwork.
They're working on something that nobody is thinking enough about—yet.
Since the 1970s, houses have changed dramatically.
In an effort to drive energy efficiency, they've become airtight.
This is great for the environment, but terrible for your health.
All the particulates, VOCs, mold spores, and moisture that used to escape is now trapped inside with you.
Radon gas in your basement.
Mold spores from that leaky pipe in the wall.
Contaminants like PFAS quietly entering our water supply.
Your home has become a completely different environment than the one humans evolved to live in.
And the risks are almost designed to be ignored, because they're so boring and innocuous.
You don't feel them, but they build up quietly over decades of exposure.
A little more inflammation.
Worse sleep.
Headaches you chalk up to stress.
Brain fog you blame on getting older.
Hell, maybe a cancer diagnosis that came a little too young.
In the meantime, your house was silently contributing to it all along.
That's what Justin's new company is working on. Helping people test their homes and protect themselves from all these problems.
I consider myself pretty nerdy about this stuff. I had my air and water tested when I moved in, plus have air purifiers all over and a filtered water tap.
Lightwork goes a level deeper. They test for mold, VOCs, radon, lighting quality, and EMF.
They sent a crew and swept my house for hours, scraping walls, moving fancy looking sensors around, and taking water samples.
A few weeks later, we got the report.
Here's what they found in our home that I had missed:
They discovered crazy high volatile organic compounds in my shower water vapor.
The kind that get inhaled and absorbed through your skin and are linked to cancer, but easily resolved with a simple shower filter.
Something I never would have thought to test.
They also found EMF hotspots throughout certain rooms.
Including—of course—the kids bedroom.
This one got an exaggerated eye roll from me, to be honest.
I made some jokes about chemtrails and 5G, but then Justin sent me the literature.
I gulped and we made some changes.
I had no clue about either of these issues, and I'm someone who actually pays attention to this stuff.
Both were quick fixes and resolved within a few weeks.
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"
One found black mold behind a wall she'd walked past a thousand times.
Another discovered her son's bedroom had the worst air quality in the house, full of VOCs.
A third had been being slowly poisoned by formaldehyde from cheap furniture.
Each was suffering from health issues, but none of them had connected their symptoms to their homes. In each case, they were an easy fix.
My friend who discovered the black mold, for example, realized it was the cause of her brutal brain fog and fatigue and was able to treat her mold exposure and recover.
It turns out that Benjamin Franklin was right: "An ounce of prevention is worth a pound of cure."
So roll your eyes all you want, but I think Justin is on point on this one. You should get your house tested.
