What this Trial Is About
Researchers are studying dehydration in college students and evaluating whether a smart water bottle intervention can help increase daily fluid intake. The study focuses on the common issue that many young adults do not meet fluid intake recommendations, which can lead to health problems like obesity, diabetes, and kidney disease. The trial aims to test if prompting from a smart water bottle combined with daily self-monitoring of hydration indicators can promote healthier drinking habits during this important life stage. Participants in the intervention group will receive a smart water bottle that lights up to remind them to drink if they are behind on fluid intake goals—2.5 liters daily for males and 2.0 liters for females, based on official guidelines. They will also use a mobile app linked to the bottle to log fluid intake and record daily thirst perception, morning urine color, and body mass on a paper log. The control group will continue their usual habits without the bottle or hydration tracking. The intervention lasts for 2 weeks. During the study, researchers will measure total fluid intake, 24-hour urine osmolality and volume, urine color, calorie intake, body composition, hydration knowledge and behaviors, and hormone changes before and after the 2-week intervention. Participants will track daily hydration signs themselves, while the study team monitors these objective and subjective hydration markers. The study is randomized with single masking and includes adults aged 18 to 35. The total study duration covers the 2-week intervention period and related assessments.
