Background: Staying hydrated at work can be difficult for many workers. Busy sche­dules make it easy to forget to drink as much water as workers should do. For some, the type of work or specialist work clothes makes it awkward to access water regularly. Alkaline water has a high­er pH level than regular drinking water. Because of this, some advocates of alkaline water be­lieve it can neutralize the acid in the body. Nabeez water was one of the drinks consumed by the Pro­­phet. It is an alkalizing tonic, having the tendency to remove acidity from the stomach and di­­gestive system and it also helps to remove other metabolic wastes from the body. This study aimed to analyze the effect of alkaline water and Nabeez water on rehydration in hot working room among machine operators.

Subjects and Method: This was a quasi-experimental study conducted in Jepara, Cen­tral Java. A total sample of 44 computer embroidery machine operators was selec­ted for this study di­­vided into 3 groups: alkaline water, Nabeez water, and control groups. Each group received 250 ml fluid every 30 minutes for 4 hours. The dependent vari­able was hydration status. The in­de­pendent variable was type of hydration water. The hydration status was measured by urine spe­cific gravity from urinometer. The data were analyzed using Kruskal Wallis test and Wil­co­xon sign rank test.

Results: There were no significant differences in the average hydration status before inter­ven­tion in all groups (p= 0.568). Average hydration status was higher in Nabeez group than alkaline group after the intervention (p< 0.001). The control group showed the lowest average hydration sta­tus among the three study groups after the intervention (p< 0.001).

Conclusion: Nabeez water is more effective in reducing dehydration status than alka­line water.
