While we are frequently reminded of the risks of dehydration, many people are unaware of the risks associated with overhydrating. Our bodies are not able to function well when we continually dilute our blood with too much water, particularly while exercising and sweating out fluids. Rather than drinking in preparation for being thirsty, we should drink only when we feel the urge.

Key Takeaways:

• “‘Research shows that during exercise problems are normally caused when you drink too much water rather than not enough,’”
• “The key is to drink little and often, and not guzzle loads of water in one go, as your kidneys can only expel half a litre of water an hour.”
• “Lastly, keep an eye on your urine – if it’s completely clear, you may be drinking too much water.”

“Hyponatremia – or water intoxication – occurs when the body takes on more water than it can sweat/pee out, causing blood sodium levels to drop to dangerous levels.”
