Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is relaxation in a flotation tank. This tank is a device filled with magnesium sulphate (Epsom salt) saturated water (1.3 g/cm^3) heated to 35-36 degrees Celsius. In the tank there is darkness and silence. Ear-plugs are used.

The participants receive a total of twelve flotation sessions (each consisting of 45 minutes) during seven weeks. There is one session every 3-4 days over the 7 week intervention period. There is a session attendance monitoring at the floatation tank centre. If a participant do not arrive, or get sick, a new scheduled session is offered.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
An agreement was made between the owner of a flotation centre and three managers from three different companies about a health-care program involving flotation-tank treatments. All three companies advertised through intranet correspondence, their company magazines, and through emails, offering all employees to participate in the health-care program. All interested participants were invited to an information meeting at the flotation centre, where they were further informed about the program. Information was given that the flotation-rest program would enable them to participate in a scientific study concerning the effects of this treatment program. Further information was given regarding that the participation was voluntary, confidential, that they would be randomly selected to either experimental group or waiting list, and that they could terminate their participation at any given point. They were also informed it was possible to participate in the health-care program without participation in the present study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
at the first meeting, the participant pulled a "lottery ticket" out of a closed box. It was written "floatation-tank" or "waiting list" on this ticket.
