HYDRATION MYTHS BUSTED<br />

At its elementary level, hydration is<br />

simple... If you feel thirsty then drink.<br />

However there is a tsunami of misinformation<br />

and we are going to tackle some of those halftruths.<br />

Hydration is one of the key ingredients<br />

to performance. Simply it transports nutrients<br />

to your cells and takes waste away from them.<br />

MYTH: Dehydration won’t impact your<br />

workout that much.<br />

Truth: False! Whether you start the any activity<br />

dehydrated or become dehydrated during that activity,<br />

if you cross the dehydration “threshold” (a 2% decrease<br />

in body weight), your exercise intensity drops off. Once<br />

you reach this dehydration threshold, you will sweat<br />

less, which will lead to a higher body temperature, and<br />

your heart rate will be higher for the same exercise<br />

intensity. Which basically means you will slow down<br />

and it impacts on what you are doing that’s is at the<br />

gym or hiking a mountain.<br />

Myth: If you’re thirsty, you’re already<br />

dehydrated<br />

Truth: Actually, your thirst sensations are a pretty<br />

sensitive gauge of your fluid levels. “Dehydration is<br />

the body’s natural loss of water through sweat, tears,<br />

and breathing. The kidneys control the water balance<br />

in the body, and when they sense the need for more<br />

water replacement, it sends a message to our brains to<br />

drink more water by making us feel thirsty,” explains<br />

kidney specialist Dara Huang, MD, founder of New<br />

York Culinary Medicine.<br />

Myth: You need a minimum of eight<br />

glasses of water a day.<br />

Truth: You do need to keep hydrated, but how<br />

much is an individual thing. Everybody, especially<br />

athletes and those at hotter temperatures have<br />

different needs. There are lots of variables; size,<br />

weight, altitude, temperature.<br />

Myth: You need to wee clear to be<br />

hydrated.<br />

Truth: As long as what coming out is a pale<br />

yellow, you're hydrated. If it's completely clear, it<br />

just means you are in overflow and what's going in<br />

is coming straight out. However if your pee is darker<br />

in colour and/or particularly smelly, you are possibly<br />

dehydrated, but it could be a range of factors.<br />

Myth: Water only is best for hydration.<br />

Truth: Although water is a great way to hydrate,<br />

it may not be the best choice in all situations. For an<br />

easy an easy activity on a coolish day, sipping water<br />

is fine. But if you're running 10 miles in the sun are<br />

going to need more water enhanced with electrolytes,<br />

are good options<br />
