Staying hydrated is a daily necessity. How much water should you drink? According to the experts at Harvard Medical School, most people need about four to six cups of water each day, however, water needs vary.

Water is the source that keeps every system in the body functioning properly. The Harvard Special Health Report 6-Week Plan for Health Eating notes that water has many important jobs, such as:

  • Carrying nutrients and oxygen to your cells
  • Flushing bacteria from your bladder
  • Aiding digestion
  • Preventing constipation
  • Normalizing blood pressure
  • Stabilizing the heartbeat
  • Cushioning joints
  • Protecting organs and tissues
  • Regulating body temperature
  • Maintaining electrolyte (sodium) balance.
  • Giving your body enough fluids to carry out those tasks means that you're staying hydrated

Tips for staying hydrated

  • All beverages containing water contribute toward your daily needs, but remember, water is always the better choice. Try to cut out caffeinated and sugary drinks leading to weight gain and inflammation
  • Limit alcohol intake to one drink per day for women, and 1-2 drinks per day for men
  • Ward off dehydration, drink fluids gradually, throughout the day
  • Water-rich foods provide fluids, such as salads, fruit, and applesauce
