Participants in this arm will receive a structured educational program aimed at increasing their daily water intake. The program is based on the principles of the Health Belief Model (HBM) and includes the following components:

Educational Sessions: Weekly group sessions led by trained health educators, focusing on the importance of hydration, the benefits of adequate water intake, and strategies to incorporate more water into daily routines.

Behavioral Strategies: Practical tips and techniques to overcome barriers to water intake, such as setting daily water goals, using water bottles, and incorporating water-rich foods into the diet.

Personalized Feedback: Individualized feedback and support provided through weekly one-on-one meetings with a health coach to track progress and address any challenges.

Educational Materials: Distribution of printed and digital materials, including pamphlets and interactive tools, to reinforce learning and support behavior change.

Participants in this arm will not receive any specific education or intervention and will follow their usual routines. This group will serve as a control to compare the effectiveness of the Health Belief Model-based education program administered to the intervention group. The daily water intake of participants in this group will be recorded using standardized intake diaries, and averages will be calculated weekly.

Participants in this group will receive a structured training program with the aim of increasing daily water consumption and reducing symptoms of dehydration. The program is based on the principles of the Health Belief Model and includes the following components:

Initial and mid-Program training: Will be conducted by a trained health educator, each lasting 60 minutes. Two weeks after the first training, the same training will be given again for reinforcement purposes.

Session Content: Covers the importance of hydration, strategies to increase water intake (using reminders, setting goals, integrating water-rich foods), and the health benefits of adequate hydration (e.g., improved cognitive function, better physical health).

Training Materials: Booklet prepared for training. Behavioral Strategies: Practical tips for overcoming barriers to drinking more water, such as setting daily water intake goals and using diaries to track progress.

In order to determine the effect of providing health belief model education on the level of water consumption; The daily water consumption amount is determined before training. After the training, they are asked to record the amount of water they will consume daily for 30 days on the record chart. Then, the amount of water consumed at 3-day intervals is called and recorded by the patient. The amount of change in daily water consumption at the end of 30 days will determine the effect level of the training.

In order to determine the effect of providing health belief model education on the change in hydration status; Before training, the specific gravity of the urine is measured using a refractometer. The same measurement is repeated 15 days later, after reinforcement training, and on the 30th day of the study. In this way, the effect of training on the change in hydration status will be determined.
