Why Hydration Matters

Water is essential for every cell, tissue, and organ in your body. Proper hydration helps regulate body temperature, transport nutrients, remove waste, cushion joints, and maintain healthy skin.

Signs of Dehydration

  • Dark yellow urine
  • Feeling thirsty or dry mouth
  • Fatigue and low energy
  • Headaches
  • Dizziness or lightheadedness
  • Dry skin and lips

Factors Affecting Water Needs

  • Exercise: Increases water loss through sweat
  • Climate: Hot or humid weather increases fluid needs
  • Altitude: Higher altitudes may increase water needs
  • Health conditions: Fever, vomiting, or diarrhea increase needs
  • Pregnancy/Breastfeeding: Requires additional fluids

Remember

While the "8 glasses a day" rule is a good starting point, individual needs vary. Listen to your body, monitor your urine color (pale yellow is ideal), and increase intake during exercise or hot weather. Foods like fruits and vegetables also contribute to your daily water intake.
