Examining the Impact of Far-Infrared Technology on Quality of Life in Older Adults.

The purpose of this study was to examine the effects of far-infrared (FIR) heat on quality of life (QOL) in older adults. Participants were assigned to either a convective heat group (CON) or a convective and FIR group. Participants received six, 30-min heat sessions over the course of three weeks. Pre- and post-assessments included physical measures such as range of motion, gait speed, Timed Up and Go, and hand grip strength. Standardized questionnaires were used to determine pain severity and its interference with daily life, and the impact pain had on overall QOL. Pain severity was significantly reduced (from 3.31 to 2.5, p  < .05) in the FIR group from pre-to-post, and pain interference was significantly reduced (from 1.26 to 0.43, p  < .05) in the CON group from pre-to-post testing. Findings suggest that heat therapy was successful in reducing pain over time.
