What a full-body bed actually does differently
Every category in red light therapy uses broadly the same wavelengths. What separates them is how much of you receives a consistent dose, and how repeatable that dose is from session to session. A bed is the only form factor where the light source geometry does that work for you: you lie down, the canopy closes, and distance and angle are fixed by the hardware rather than by how carefully you positioned yourself that day.
That matters more than it sounds. With a panel, the parts of you nearest the centre receive noticeably more energy than the edges, and small changes in how far back you stand change the dose substantially. A bed removes both variables, which is why whole-body goals — recovery, sleep, skin across large areas — tend to be discussed in the context of beds rather than panels.
It also removes friction, which is the quiet reason people succeed or fail with red light. A routine that takes one 15-minute block is one you keep; a routine that requires four repositioned blocks is one you abandon in week three.
