Reviews
“I love it and definitely feel a difference with it on. As someone with […] I plan to use it daily. It's a little too big for my neck though, so I have to get creative to tie it.”
“Very responsive, heard directly from the founder twice”
“Lighter than I expected. After the first minute I forget I’m wearing it at all.”
“Slips into my backpack without a thought. Genuinely travel-friendly.”
“Three wavelengths in a single band. That was the part that sold me on the design.”
“Wipes clean in seconds. No special routine, no fuss.”
“Runs off any USB-C [PD] power bank I already own. A small thing that matters every day.”
“Comfortable enough that I keep wearing it while I’m reading. The silicone sits well.”
“Small footprint, but it doesn’t feel cheap or underpowered.”
“A quick wipe with a damp cloth and it looks new again. Practical design choices throughout.”
“Compact, quiet, and easy to live with. It doesn’t ask anything of me.”

Your quiet twenty. Daily.
Strap it on.
The silicone band wraps your neck like a soft collar. Wear it at home, at your desk, on the train. At 80 grams, you stop noticing it.
Plug it in.
Use the included USB-C plug at home or any USB-C PD power bank on the go. No battery inside, by design.
Push the button.
The handheld control pod has three buttons: power, session length (15 / 30 / 60 min) and intensity (25 / 50 / 75 / 100%). A quiet tone tells you when the session ends.
Regularity matters.
Pick a time of day and keep it. Ours is the morning: coffee, light, and a quiet twenty.
Front and back. Drag to compare.

The science behind the light.
Red and near-infrared light at 630, 660 and 830 nm are among the most-studied wavelengths in light research. We didn't invent the science. We built a device around it, shaped for your neck.
Read what the studies sayThe thyroid sits just under the skin at the front of your neck.
ThyRed puts steady light on exactly that spot.
Engineered around four principles.
Shaped for the neck.
A curved silicone band that sits on the front of your neck.
Total wattage ≠ targeted dose.
Cellular response follows a biphasic pattern. ThyRed prioritises a controlled, distributed dose over raw peak power.
630 / 660 / 830 nm.
27 high-efficiency LEDs at three widely studied red and near-infrared wavelengths.
Under 3 mG at the skin.
Measured by an independent lab under EN 62233, the European standard for EMF exposure from household devices.
ThyRed Base.
Most orders arrive within 7 to 10 days. Some destinations take longer.
Your 30-day return window starts on arrival.
ThyRed is a light therapy device worn on the neck. It uses red light (630 and 660 nm) and near-infrared light (830 nm), aimed at the area around the thyroid.

Home users and wellness professionals use ThyRed as part of a personal wellness routine. ThyRed is intended for general wellness and is not designed to diagnose, treat, cure, or prevent any medical condition. Research into the biological effects of red and near-infrared light is growing. Users often report feeling more relaxed, sleeping better, and having steadier energy. Individual responses vary, and we cannot guarantee specific outcomes. There are no known adverse effects with normal use. Talk to a qualified healthcare professional before use. This information is educational and is not a substitute for professional medical advice.
ThyRed uses moderate-irradiance over a timed session: even, controlled light instead of peak output.

Honest answers.
If you don't see your question here, write to us. Real humans, usually within a day.
Is NIR light therapy safe?
Yes. It is non-invasive, with no known serious side effects when used as directed. ThyRed tested Exempt Group under EN 62471, the lowest risk class for light safety.
How long should I use the device per session?
Typically 20 to 30 minutes, a few times a week. Ease in: start with 20-minute sessions at the lowest intensity (25%) for a couple of weeks, then step up to 50%, and so on.
Is the device emitting heat during a session?
ThyRed has 4 intensity levels. At the highest, it feels like holding a slightly warm teacup. The LEDs never touch your skin: a thin silicone layer sits in between for comfort and safety. Even after 30 minutes or more, the surface stays around 40 °C (104 °F) at room temperature.
Why do some LEDs look switched off?
Near-infrared light is mostly invisible to the human eye. 15 of the 27 LEDs are near-infrared (830 nm). You may see a faint purple glow or nothing at all, but they are on and working.
What is the difference between red light and NIR light?
Both are part of sunlight. Red light covers roughly 600 to 700 nm. Near-infrared (NIR) covers roughly 700 to 1000 nm and is mostly invisible. NIR reaches much deeper than red light, through soft tissue, connective tissue, and bone. Each has its own effects on cells.
Why doesn’t ThyRed come with an integrated battery?
On purpose. Built-in batteries wear out, which creates waste and often means replacing the whole controller. ThyRed runs from any USB-C PD power bank or a USB-C PD plug instead, so there are fewer parts to fail and the device lasts longer. For best results, use the equipment in the box.
What’s your return policy?
30 days, no hassle. We pay return shipping worldwide. No restocking fee. Send it back in the original packaging with all accessories and we issue a full refund after inspection.
Defective unit? Email hello@thyred.com. We pay for shipping and send a replacement the same day your return arrives.
Every device includes a 1-year warranty against manufacturing defects.
