“…Rehydration is commonly prescribed for supporting healthy voice production. 1,2 While such a recommendation is intuitive and unlikely to be deleterious in an otherwise healthy individual, it is predicated on the assumption that rehydration reverses physiological changes associated with dehydration. However, our understanding of the pathophysiology of vocal fold dehydration remains incomplete, and a more comprehensive understanding of rehydration (intentional hydration following dehydration) is needed to validate the clinical efficacy of rehydration rigorously.…”

ObjectiveBiological data on the beneficial effects of vocal fold rehydration are lacking. This study aimed to examine the effects of acute systemic dehydration on vocal fold gene expression and determine whether rehydration would reverse these changes.MethodsMale New Zealand White rabbits (N = 24, n = 8/group) provided the animal model. Systemic dehydration was induced by 5 days of water volume restriction. Rehydration was provided by ad‐lib water for 3 days following dehydration. Euhydrated rabbits were used as the control group. Vocal fold tissue was dissected. Seventeen genes were selected based on physiological function and role in supporting vocal fold structure, oxidative stress, hemodynamics, and extracellular matrix turnover. Relative gene expression was assessed by RT‐qPCR.ResultsRehydration following systemic dehydration can modulate gene expression, with expression patterns suggesting that rehydration reverses dehydration‐induced changes in over half of the tested genes. CLIC5 (chloride intracellular channel 5) and EFEMP1 (EGF containing fibulin extracellular matrix protein 1) genes were significantly upregulated in the dehydration group compared with the euhydrated control. A1BG (alpha‐1B‐glycoprotein) and IL1RAP (interleukin 1 receptor accessory protein) were downregulated by rehydration compared with the dehydration group.ConclusionThis study provides molecular evidence for a transcriptional response to rehydration following acute systemic dehydration in the vocal folds. These data are the first to study gene expression following realistic dehydration and rehydration paradigms and provide biological data to support clinical recommendations to increase water intake after acute dehydration.Level of EvidenceN/A Laryngoscope, 2023

Purpose of Review Discuss current literature and clinical experience related to vocal hygiene, with special consideration for the professional and performing voice user. Recent Findings Use and non-use-related vocal hygiene factors that may impact professional and performing voice users include hydration, laryngeal irritants, phonotrauma, and voice rest. Key considerations include monitoring both systemic and surface hydration, maintaining awareness of key signs and symptoms of reflux, avoiding phonotraumatic patterns and/or learning to pace voice use when high-impact vocal behaviors are required. Complete voice rest is better suited to treat acute injury and not practical for day-to-day vocal management. Summary Vocal hygiene is one tool within voice therapy that plays a key role in vocal injury prevention and rehabilitation when paired with direct voice therapy. Vocal hygiene education should be individualized, guided by the tenants of meta-therapy and motivational interviewing to increase self-efficacy for change and adherence to recommendations.
