660nm — the surface
Red light. It stops near the skin.

Why the light works
Two kinds of light. One goes deeper.
660nm reaches the skin. 850nm keeps going into the tissue underneath, which is where everyday stiffness sits. Wecct runs both at once.
850nmNear-infrared
850nm — deeper
Near-infrared. It travels further in, into muscle and joint tissue.
The belt, the mat and the blanket all run both.

The ritual
Twenty minutes you do not have to arrange
It happens inside your evening, not instead of it.
Step 01
Lie down or put it on
A mat lies flat on the bed or the floor. A belt goes around your waist. Whichever suits where you sit.
Step 02
Press start once
One button, five levels. That is the whole control panel.
Step 03
Carry on
Make tea, read, or doze off. The timer stops it for you.

Wide application
Where the light goes
Waist, back, shoulders, knees. Wherever it feels stiff.
Questions, answered plainly
Does it cover the head as well?
Yes. When it is laid out over you it reaches the head. If you would rather have your face free, fold the upper edge back.
Will I get too hot under it?
It gives off light rather than heat, and the fabric is soft and breathable. If it feels warm, use a thin layer underneath, or turn the level down.
How long does it take to lay out?
Less than a minute. Most people leave it over the back of a chair or at the foot of the bed so it is ready.
Is it heavy?
It is a large item but not a heavy one. It can be moved by one person.
Can I use it while sitting up?
Yes. It can be pulled over your lap and shoulders while you are seated. Whatever position you choose, the timer works the same way.
