Hydration is an essential aspect of maintaining good health, especially for students who need to stay focused and energetic throughout their demanding academic schedules. However, while the importance of hydration is well-recognized, the dangers of overhydration are often overlooked. Overhydration, or water intoxication, can be just as harmful as dehydration, posing serious health risks. In this blog, we will explore the issue of overhydration in students, focusing on why it occurs, its dangers, and how to maintain a healthy balance.

Why is hydration important for students?

Staying hydrated is crucial for students to maintain focus and performance. Dehydration can lead to fatigue, decreased cognitive function, and difficulty concentrating. Proper hydration is especially important during long study sessions or exams when the brain is working overtime. Water helps transport nutrients to the brain and flush out toxins, aiding optimal cognitive function.

By staying hydrated, students can enhance memory, concentration, and overall academic performance. Additionally, staying properly hydrated promotes overall well-being by regulating body temperature, aiding digestion, and supporting joint health.

The definition and causes of overhydration?

Overhydration, also known as water intoxication or hyponatremia, occurs when you drink more water than your kidneys can excrete, leading to an imbalance in electrolytes, particularly sodium. This can happen during intense physical activities, especially if large amounts of water are consumed without replacing electrolytes lost through sweat.

Certain medical conditions, such as kidney problems or hormonal imbalances, can also contribute to overhydration, impairing the body's ability to regulate water levels. Overhydration sometimes results from misconceptions about the benefits of drinking excessive water.

The health risks of overhydration for students

Overhydration poses significant health risks, especially when fluid intake is not properly balanced. Drinking excessive amounts of water can lead to hyponatremia, where the sodium levels in the blood become dangerously low.

Dehydration symptoms include nausea, headaches, confusion, and in severe cases, seizures, and coma. Students engaged in sports or exercise are particularly at risk if they consume too much water without replacing lost electrolytes. Overhydration can strain the kidneys, leading to decreased kidney function over time. In extreme cases, it can cause swelling in the brain and potential brain damage.

Common reasons students forget to drink water during class

Focus on lessons and activities

Engaging lessons and activities can cause students to forget to hydrate unintentionally. The excitement of learning and participating in various tasks can consume attention, leading to overlooked hydration needs. When intensely focused, taking a moment to drink water might slip the mind.

Restrictive class schedules and limited breaks

Limited break times and packed schedules often lead students to overlook staying hydrated. With back-to-back classes, it’s easy to rush from one lesson to the next without drinking water. The pressure to complete tasks and meet deadlines can also cause students to forget hydration.

Lack of readily available water sources

The lack of easily accessible water sources in classrooms can make it difficult for students to remember to drink water. When there’s no nearby water fountain or permission to bring water bottles to class, students might prioritise staying in place over hydrating. This can lead to dehydration, especially during long classes.

Social dynamics and peer influence

Peer interactions and social dynamics can distract students from remembering to drink water. Engaging in group discussions during breaks, being hesitant to leave the classroom to refill a glass waterbottle, or feeling self-conscious about drinking water in front of classmates can all impact hydration levels.

Which students are most prone to dehydration?

Understanding which students are most susceptible to dehydration helps target preventive measures effectively. Several factors contribute to this susceptibility:

Geographic Differences: USA and Canada

• Climate Impact: Students in warmer climates, such as the southern USA, are more prone to dehydration due to increased perspiration. Conversely, students in colder climates might drink less water because they feel less thirsty, increasing dehydration risk.
• Cultural Differences: Cultural attitudes towards hydration can vary. In some regions, students might not be encouraged to drink water regularly, contributing to dehydration.

Field of Study

• Accounting students: Often lead sedentary lifestyles, focusing on prolonged tasks such as analyzing data, leading to reduced water intake.
• Science students: Experience variable schedules and environments, such as long lab hours, which can promote or hinder regular hydration.

Age Differences

• High School Students: High school students typically have structured schedules with limited autonomy. They depend on school-provided resources and scheduled breaks, which might only sometimes accommodate adequate hydration.
• University Students: Students have more autonomy but face increased physical and mental stress. Due to busy schedules, they might neglect hydration, leading to cycles of dehydration and overhydration.
• College Students: College students encompass diverse age groups and schedules, leading to varying levels of awareness and habits regarding hydration. Some might be well-informed, while others might neglect it entirely.

Balancing hydration: Best practices for students

To avoid the extremes of dehydration and overhydration, students should adopt best practices for maintaining proper hydration throughout the day.

Tips for maintaining proper hydration

• Setting reminders: Use a water bottle reminder to drink water at regular intervals.

• Carrying a personal water bottle: Ensures access to water at all times, and carries a WaterH Boost Smart Water Bottle to make it easier to sip throughout the day.

Educating students on the signs of both dehydration and overhydration

• Recognizing early symptoms: Teach students to recognize early symptoms of dehydration (dry mouth, fatigue, dizziness) and overhydration (nausea, headache, confusion).
• Knowing when to drink and pause: Educate students on balanced hydration, helping them understand when to drink water and refrain.

Role of educational institutions in promoting healthy hydration habits

• Providing accessible water stations: Ensure water fountains and dispensers are conveniently located and maintained.
• Incorporating hydration breaks into schedules: Schedule short breaks between classes to encourage regular water intake.
• Offering educational resources: Include information on healthy hydration in health education curricula, promoting awareness from an early age.

Conclusion

Staying hydrated is crucial for overall health and well-being, but students must be mindful of overhydration and its potential risks. By listening to their bodies and drinking water in moderation, students can find a balance. Stay informed about the causes and symptoms of overhydration, and practise healthy hydration habits to keep the mind sharp and the body healthy. Drink responsibly and maintain proper hydration to succeed academically and physically.
