3. INTRODUCTION
●Hydration refers to maintaining an
adequate balance of fluids in the body.

●Water is essential for various biological
functions, from cell metabolism to
temperature regulation.

●On average, water makes up about
60% of the human body.

4. IMPORTANCE OF WATER IN THE BODY
●Blood Circulation: Water helps transport
nutrients and oxygen through the bloodstream
●Cell Function: Essential for cellular metabolism,
energy production, and growth.
●Temperature Regulation: Helps regulate body
temperature through sweating and respiration.
●Lubrication: Maintains moisture in tissues like
eyes, nose, and mouth, and lubricates joints.

5. HYDRATION & NUTRITION
➢Hydration is closely tied to nutrition because:

●Digestion: Water aids in the breakdown of food
and nutrient absorption.
●Nutrient Transport: Water-soluble vitamins (e.g.,
Vitamin C and B-complex) require water for
transportation in the body.
●Detoxification: Helps the kidneys filter waste
products.

6. DEHYDRATION - CAUSES & EFFECTS
●Causes: Inadequate fluid intake, excessive
sweating, diarrhea, or fever.

●Symptoms: Thirst, dizziness, dry mouth, fatigue,
and dark urine.

●Long-Term Effects: Can lead to kidney stones,
urinary infections, and impaired cognitive
function.

7. HOW MUCH WATER DO WE NEED ?
➢General Guidelines:
●Men: ~3.7 liters/day
●Women: ~2.7 liters/day
These values can vary based on physical activity,
climate, and health conditions.
➢Sources of Hydration:
●Water (primary source)
●Fruits and vegetables (e.g., watermelon,
cucumbers)
●Beverages like herbal teas and milk also contribute.

8. HYDRATION IN DIFFERENT AGE GROUP
➢Children and Adolescents:
●Need plenty of fluids, especially during growth
spurts and physical activity.
●Dehydration in children can affect their cognitive
function and academic performance.
➢Elderly:
●Sensation of thirst diminishes with age,
increasing the risk of dehydration.
●Important to monitor fluid intake, especially in
hot weather.

9. MYTHS & FACTS
●Myth: You need to drink exactly 8 glasses of water
a day.

●Fact: Fluid needs vary per person and include all
sources of fluids, not just water.

●Myth: Caffeinated drinks dehydrate you.

●Fact: While caffeine has a mild diuretic effect,
drinks like coffee and tea still contribute to overall
hydration

10. CONCLUSION
●Hydration is Integral to Health
●Dehydration Risks
●Hydration is Personal
●Hydration and Balanced Nutrition
●Prevention of Long-Term Health Issues
●Practical Hydration
