In physiology and medicine, dehydration (hypohydration) is defined as the excessive loss of body fluid. It is literally the removal of water (Ancient Greek: ὕδωρ hýdōr) from an object; however, in physiological terms, it entails a deficiency of fluid within an organism. Dehydration of skin and mucous membranes can be called medical dryness.
There are three types of dehydration: hypotonic or hyponatremic (primarily a loss of electrolytes, sodium in particular), hypertonic or hypernatremic (primarily a loss of water), and isotonic or isonatremic (equal loss of water and electrolytes). In humans, the most commonly seen type of dehydration by far is isotonic (isonatraemic) dehydration which effectively equates with hypovolemia, but the distinction of isotonic from hypotonic or hypertonic dehydration may be important when treating people who become dehydrated. Physiologically, dehydration, despite the name, does not simply mean loss of water, as water and solutes (mainly sodium) are usually lost in roughly equal quantities to how they exist in blood plasma. In hypotonic dehydration, intravascular water shifts to the extravascular space, exaggerating intravascular volume depletion for a given amount of total body water loss. Neurological complications can occur in hypotonic and hypertonic states. The former can lead to seizures, while the latter can lead to osmotic cerebral edema upon rapid rehydration.
Faith is falling
Thoughts come undone
And every single cell inside your body goes
Numb, just like it never did before
Just like it never did
My faith failing
Where’d it come from
And every single cell inside my body is numb
Shout to anyone in the dark
Feel these words that create a spark
‘Cause there’s a...
Fire that burns us
And we can’t live without water
Face the flood ‘cause it’s going under
And only those without wings will die
People speak and sing and stand up
But words aren’t enough to fill my cup
When there’s a...
Looking up, how I’d love to join them
But I never learned to fly
I never learned to fly
(That’s not the reason)
That I have never tried
(What you believe in)
I guess it seemed so tired
(What you believe in)
So face your own flood
Together we…
Drown, just like we never did before
