As soon as you feel like you're thirsty, you're already dehydrated. So goes the accepted wisdom when it comes to necessary water intake in the body, but that's not the only sign you should be watching out for.

According to naturopathy expert Sal Graziano in the video above, as soon as you start exerting yourself more (both physically and mentally), your intake of protein and water has to go up as well. Yes, that's right -- it's not only workouts that make you dehydrated, but mental stress as well.

Other signs your body is already dehydrated include a lack of elasticity when you pinch your skin, a sticky mouth, and low to no urine output.

Equally as important is how the lack of water in your system can affect your cognitive processes. Studies earlier this year found dehydration to be the cause of bad moods and low energy, while other research has linked it to asthma and high blood pressure.
