However, the treatment of pain can be difficult, as pain perception is complex and can be affected by factors other than tissue damage. This study investigated the effect of hypohydration (mild, voluntary dehydration from \u223c24 h of limiting fluid intake, mimicking someone drinking less than usual) on a person's pain perception. Seventeen healthy males (age 27\u2009\u00b1\u20095 years) visited the laboratory on three occasions, once as a familiarization and then twice again while either euhydrated (urine specific gravity: 1.008\u2009\u00b1\u20090.005) or hypohydrated (urine specific gravity: 1.024\u2009\u00b1\u20090.003, and \u22121.4\u2009\u00b1\u20090.9% body mass). Each visit, they performed a cold pressor test, where their feet were placed in cold water (0\u20133\u00b0C) for a maximum of 4 min. Measures of hydration status, pain sensitivity, pain threshold, and catastrophization were taken. We found that hypohydration predicted increased pain sensitivity (\u03b2\u2009=\u20090.43), trait pain catastrophizing, and baseline pain sensitivity (\u03b2\u2009=\u20090.37 and 0.47, respectively). These results are consistent with previous research, and suggest that a person's hydration status may be an important factor in their perception of acute pain.<\/jats:p>","DOI":"10.1111\/psyp.12610","type":"journal-article","created":{"date-parts":[[2016,1,20]],"date-time":"2016-01-20T15:17:50Z","timestamp":1453303070000},"page":"605-610","source":"Crossref","is-referenced-by-count":30,"title":["A preliminary study on how hypohydration affects pain perception"],"prefix":"10.1111","volume":"53","author":[{"given":"Tracey","family":"Bear","sequence":"first","affiliation":[{"name":"School of Sport and Exercise Massey University Palmerston North New Zealand"},{"name":"School of Psychology Massey University Palmerston North New Zealand"},{"name":"School of Food and Nutrition Massey University Palmerston North New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Philipp","sequence":"additional","affiliation":[{"name":"School of Psychology Massey University Palmerston North New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Hill","sequence":"additional","affiliation":[{"name":"School of Psychology Massey University Palmerston North New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toby","family":"M\u00fcndel","sequence":"additional","affiliation":[{"name":"School of Sport and Exercise Massey University Palmerston North New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,1,20]]},"reference":[{"key":"e_1_2_5_2_1","unstructured":"Access Economics.
