What Would Happen if You Didn’t Drink Water? is the title of latest TED-Ed lesson. The lesson addresses items like how much water should a person drink, how much water a body loses during an average day, and the effects of dehydration. The lesson also addresses what can happen when you consume too much water.

This lesson is the latest that I’ve added to a playlist that I call TED-Ed Human Body. Some of the other lessons in the playlist cover blood pressure, kidney function, and liver function. The entire playlist is embedded below.
