Can you drink too much water? Here's what experts say

While most people have heard the advice to drink eight cups of water a day, there is some flexibility there and people are capable of drinking both too much and too little, though the latter is more common. 

Drinking too little can lead to dehydration which can cause a range of symptoms from dizziness to, in some extreme cases, death. Drinking too much also has potentially dangerous impacts because too much water in the body affects the body's electrolyte balance, experts said. They shared advice for how much a person should be drinking and the signs someone has had too much water -- and if the right balance exists for the average water drinker.
