Water might seem like the least harmful substance on the planet, but drinking too much of it can kill.
So can too much or too little of a number of other things most of us take for granted, from caffeine to the stuff you use to clean your bathroom.
Coffee's great for making you feel more alert and boosting your attention span, and at low doses, it's perfectly safe.
But at high concentrations, caffeine can cause insomnia, dizziness, vomiting, headaches, and heart problems , and too much in one sitting can be deadly.
The risk of overdoing it is highest for pure powdered caffeine. A single tablespoon of this stuff — the equivalent of about 120 cups of coffee — can kill.
During the summer of 2014, two young men died in separate incidents after each drank mixtures of pure powdered caffeine and water.
Water regulates the shape of the cells inside our bodies — too much of it, and they puff up like balloons; too little, and they shrink.
An excess of water in and around our cells is called water intoxication, or hyponatremia. Drinking too much water, something athletes can do accidentally while training, can cause it. A 2005 study of 2002 Boston Marathon runners, for example, found that about 1/6th of the runners they studied had a mild form of the condition, with symptoms ranging from nausea to vomiting.
But an extreme case of water intoxication takes its worst toll on the brain, where our tightly-packed neurons have little room to accommodate the extra water. A variety of neurological problems can result, from headaches to confusion, seizures, and, in rare untreated cases, death.
One of the most well-known cases of water intoxication happened in 2007, when 28-year-old Californian Jennifer Strange downed six litres of water in under three hours as part of a radio station contest. Strangely, Jennifer died a few hours later.
Crazy, huh? So no matter what it is in life, water, caffeine, food, exercise and even too much work can take a toll on your body. The key is consistency, and balance.
