Full-Body Red Light Bag
About 20 square feet of skin, front and back, lit at once. That’s the size of a front door. Lie down for 20 minutes and let your mitochondria do the rest.
79 in. long, 35 in. wide. Tall and broad bodies zip all the way in, head to feet.
Free, tracked US shipping.

Almost every one of your cells contains mitochondria, the power plants that turn food and oxygen into ATP, the energy your body spends on everything from blinking to rebuilding muscle.
One enzyme on that assembly line, cytochrome c oxidase, absorbs red and near-infrared light. That’s the whole idea behind red light therapy: a specific color, absorbed by a specific part of the cell.
A solar panel bolted onto a power plant. Red light doesn’t add fuel. It helps the plant run the fuel it already has.

One session
The light reaches every side of you at once, so a full-body session takes the time a face mask does.
Recovery
Creatine kinase is your muscles’ check-engine light: it leaks into your blood when fibers tear. A meta-analysis of controlled trials found light before exercise improved performance and lowered it.

Skin
136 people used full-body red light units twice a week for 30 sessions. Ultrasound measured higher collagen density than in the control group.

Wind-down
Your eyes have a daylight sensor that’s most sensitive to blue light and barely notices red. That’s why a campfire feels like night and a phone feels like noon.
Brainard et al. · J Neurosci · 2001How it works
Light between roughly 650 and 1,350 nanometers sits in the body’s optical window: the range where blood and water absorb the least, so light travels the furthest. Longer wavelengths reach deeper.
Absorbed in the top layers of skin. The wavelength used in most skin studies.
Invisible to you, and it travels further into tissue, toward muscle and joints.

Myth vs truth
Red light is just a fancy heat lamp.
Heat is something you feel. The effect studied in red light therapy depends on color, not warmth: specific wavelengths get absorbed by one specific enzyme in your mitochondria. A space heater warms the room. It doesn’t change how your cells make energy.
Karu · IUBMB Life · 2010If 20 minutes is good, an hour is better.
Light follows a biphasic dose response: too little does nothing, the right dose helps, and too much can cancel the benefit. It’s watering a plant, not filling a pool. Use the timer.
Huang et al. · Dose-Response · 2009A wall panel does the same job.
Light obeys the inverse-square law: twice the distance, a quarter of the light. A panel also only reaches the side of you facing it. Lying inside the light, front and back, removes both problems.
Inverse-square lawFit
Your head, your shoulders and your feet are all inside the light. The three-sided zip opens flat, so you lie down instead of wriggling in.
Your protocol
Red light doesn’t trip your daylight sensor, so evening sessions fit right before sleep.
Start on a low intensity level. The timer ends the session for you.
The whole-body skin trial used two a week for 30 sessions. Consistency beats intensity.
The research
Every claim on this page points to a published paper. Here they are.
Full-body red light units, twice a week for 30 sessions. Skin complexion and roughness improved, and ultrasound measured higher collagen density than in the control group.

Yes, up to 6'5". The bag is 79 inches long and 35 wide, and the zip runs around three sides so it opens flat and you lie down instead of squeezing in.
It feels warm, not hot. You can lower the intensity at any time.
The light is bright up close. Wear the included goggles, or keep your eyes closed when your face is lit.
Three to five sessions a week. Start on a low intensity level and let the timer end the session.
Wipe it with a soft, slightly damp cloth after use. Never put it in the washer or submerge it.
Yes. Start a return within 30 days of delivery by emailing info@tharsyn.com. The refund policy has the conditions.
