Note

Opposite: «dehydrated» (not enough water). «Hydr-» comes from Greek for water (hydrant, hydroelectric). A safety point: thirst, headache, tiredness and dark urine can be signs you need more water. Myth: everyone needs exactly eight glasses a day — needs depend on age, weather and activity, and food also contains water.
