How to do it

  1. For most healthy people, about 4 to 6 cups of plain water a day is a reasonable baseline. Other drinks and water-rich foods count toward your total fluids.
  2. Carry a reusable bottle and refill it at set points, such as each meal or each break.
  3. Make water your default drink at meals and when eating out. Add lemon, lime, cucumber or berries if plain water is a hard sell.
  4. Drink more when it is hot or when you are sweating from work or exercise.
  5. Watch for dark yellow urine, which suggests you need more.

Why it helps

Water carries nutrients, cushions joints, regulates body temperature and keeps your kidneys flushing waste. Busy shifts, air-conditioned offices and long drives make it easy to go hours without drinking. Older adults may not feel thirsty even when they need fluids.

Be careful

More is not always better. If you have heart, kidney, liver or thyroid disease, or take medicines that make you retain water (some pain relievers and antidepressants), ask your doctor how much you should drink.
