The aim of this study is to investigate the role of hydration and fluid intake in children and adolescents with primary headaches.

Headches are one of the key factors affecting or even limiting the health and well-being of children and adolescents. Lifestyle recommendations could help reduce the risk of chronic headaches and improve overall well-being in this population. In clinical practice, adequate fluid intake is one of the general recommendations for headache management. However, scientific literature on the role of hydration and fluid intake in headaches is limited. To date, all studies have been conducted on adults, and no studies have examined this topic in the pediatric population.

As the first interventional study investigating the impact of adequate fluid intake on headaches in children and adolescents, our study will make a significant contribution to understanding the role of hydration in headache management and developing recommendations for improving headache control in the pediatric population.
