Welcome!
I'm Valerie, Founder and CEO of Halsa. Thank you so much for being here and for taking a moment to learn a little more about the heart behind this brand.
Halsa was created to offer thoughtful, everyday products that support health and well-being — starting with protection from electromagnetic frequency (EMF) radiation, and growing into a broader lifestyle rooted in intentional living and self-care.
How Halsa Started
The idea for Halsa began while doing one of my favorite things: long-distance running. I often went for long outdoor runs while holding my iPhone, listening to podcasts, audiobooks, or music through Bluetooth headphones. At some point, it struck me as odd — I was running outdoors to improve my health and longevity, yet I was simultaneously exposing my body to constant EMF radiation from my phone and Bluetooth devices.
That realization led me to purchase an EMF-shielding phone case and switch back to wired headphones. Still, it didn't feel like enough. I wanted to do more to protect my body — especially the areas closest to these devices. Through research, I discovered silver fiber fabric and its shielding properties, and that was the moment Halsa was born.
I created Halsa to provide affordable, wearable EMF-protection products that can be used every day — because EMF exposure isn't just from our phones; it's all around us.
The Sauna Chapter
As Halsa has grown, so has the vision. The biggest evolution has been our line of wool sauna hats — a category I fell into through my own wellness routine and stayed in because I couldn't believe how much of a difference the right hat made.
The first time I tried a wool sauna hat, I lasted noticeably longer in the sauna, my scalp wasn't burning, and my hair wasn't dried out for days afterward. I went looking for a hat I genuinely loved — premium materials, clean design, real protection — and ended up making my own. That's how the Halsa sauna hat line was born.
Today, our flagship Bucket Wool Sauna Hat is the one most customers start with. It's the silhouette I personally reach for and the most forgiving fit across head sizes. For people who sauna often, we also offer the Merino Wool 2-Pack — two hats so one is always dry and ready while the other airs out. And for anyone who wants something more playful, our Mushroom and Viking hats use the same premium wool with a little more personality.
Every Halsa hat is 100% natural wool, designed to handle real sauna conditions, and built to last for years of regular use. New to sauna hats? Start with our deep dive on the benefits, browse our best sauna hats of 2026 ranked by category, or read the full wool sauna cap buyer's guide.
What We Stand For
Halsa products come directly from my own wellness routines — tools I personally use and believe in to support long-term health, balance, and vitality. We don't chase trends, we don't make medical claims we can't back up, and we don't cut corners on materials. Every product we add to the lineup has to earn its place by being something I'd genuinely want in my own home.
My hope is that every Halsa product helps you feel more mindful, more protected, and more supported in your everyday life.
Thank you genuinely for being here and for supporting this journey. Halsa translates to "health" in Swedish, and our mission is simple: to help keep you healthier through thoughtfully designed products you can trust.
With health and happiness,
Valerie
Founder of Halsa
