Chronic pain - pain that persists for more than 3 months - is a global health problem and is associated with tremendous social and economic cost. Yet, current pain treatments are often ineffective, as pain is complex and influenced by numerous factors. Hypohydration was recently shown to increase ratings of pain in men, but studies in this area are limited ( = 3). Moreover, whether hypohydration also affects pain in women has not been examined. In women, changes in the concentrations of reproductive hormones across menstrual phases may affect pain, as well as the regulation of body water. This indicates potential interactions between the menstrual phase and hypohydration on pain, but this hypothesis has yet to be tested. This review examined the literature concerning the effects of the menstrual phase and hypohydration on pain, to explore how these factors may interact to influence pain. Future research investigating the combined effects of hypohydration and menstrual phase on pain is warranted, as the findings could have important implications for the treatment of pain in women, interpretation of previous research and the design of future studies.
慢性疼痛——持续超过3个月的疼痛——是一个全球性的健康问题，并且与巨大的社会和经济成本相关。然而，由于疼痛复杂且受众多因素影响，目前的疼痛治疗往往效果不佳。最近有研究表明，水分摄入不足会使男性的疼痛评分增加，但该领域的研究有限（n = 3）。此外，水分摄入不足是否也会影响女性的疼痛尚未得到研究。在女性中，月经周期各阶段生殖激素浓度的变化可能会影响疼痛以及身体水分的调节。这表明月经周期和水分摄入不足在疼痛方面可能存在潜在的相互作用，但这一假设尚未得到验证。本综述研究了有关月经周期和水分摄入不足对疼痛影响的文献，以探讨这些因素如何相互作用来影响疼痛。鉴于研究结果可能对女性疼痛治疗、既往研究的解读以及未来研究的设计具有重要意义，因此有必要开展进一步的研究来探究水分摄入不足和月经周期对疼痛的综合影响。
