A normal water-electrolyte balance is essential for normal function of body systems during physical activity. During recent years, awareness of the importance of drinking amongst athletes and Israeli Defense Force (IDF) soldiers, in particular, has been highlighted. A large number of athletes tend to drink prior to, during and after their exercise in order to enhance physical abilities and to prevent heat casualties and dehydration. However, excessive water consumption combined with sweat induced electrolytes loss during physical activity, may cause hyponatremia in extreme cases. Recently, several cases of exercise induced hyponatremia were reported in the IDF, resulting from improper water consumption. In this article, we describe a clinical case of exercise-induced hyponatremia in a soldier and a review of the literature, including the etiology, clinical characterization and recommended treatment. Moreover, water consumption recommendations with regard to physical activity are presented. The application of such recommendations may prevent future events of exercise-induced hyponatremia.
在体育活动期间，正常的水电解质平衡对于身体各系统的正常功能至关重要。近年来，运动员尤其是以色列国防军（IDF）士兵对饮水重要性的认识得到了强调。大量运动员倾向于在运动前、运动中和运动后饮水，以增强体能并预防热损伤和脱水。然而，在体育活动中过量饮水并伴有汗液导致的电解质流失，在极端情况下可能会引起低钠血症。最近，以色列国防军报告了几例因饮水不当导致的运动性低钠血症病例。在本文中，我们描述了一名士兵运动性低钠血症的临床病例，并对相关文献进行综述，包括病因、临床特征和推荐的治疗方法。此外，还给出了有关体育活动饮水的建议。应用这些建议可能会预防未来运动性低钠血症的发生。
