Mild dehydration is relatively common and can affect factors which also affect pain perception e.g. hormones (Aloisi, 2003), sleep (Wright et al., 2007), and mood (Ganio et al., 2011; Sullivan, et al., 2000). There is little research on the link between hydration and pain perception, but it has implications for the clinical treatment of pain, as medical or psychological treatments could be less effective if there are physiological factors such as dehydration contributing to a person’s pain experience. Most dehydration studies have used heat, exercise, diuretics or a combination of these to induce dehydration, which does not reflect the real life situation of simply not drinking enough fluid, and introduces confound. This study investigated the link between hydration, pain catastrophizing, and pain perception.
