Drinking water at a certain time maximizes its effectiveness on the body:

2 glasses of water after waking up - helps activate internal organs 

1 glass of water 30 minutes before a meal - helps digestion   (It also help curb your appetite)

1 glass of water before taking a bath - helps lower blood pressure

1 glass of water before going to bed - avoids stroke or heart attack

Drinking water after eating reduces the acid in your mouth by 61 percent.

If you stop getting thirsty, you need to drink more water. When a human body is dehydrated, its thirst mechanism shuts off.
