Fibromyalgia and Circadian Blood Pressure

Participants randomized to this treatment will receive a whole body PBM treatment using a NovoTHOR® whole body light bed. For each treatment session, participants will lie supine in the treatment bed for 20 minutes, with no or minimal attire (underwear). Treatment sessions will be three times weekly for a period of 4 weeks, totalling 12 treatment sessions

The placebo feature of the whole body PBM bed provides controls that select active or placebo (sham) treatments in a way undetectable by participant, operator or observers, such that no-one is aware whether the participant is receiving an active or placebo treatment. There is a switch box that randomises participants to active or placebo; no other randomisation is necessary.
