Staying well hydrated, particularly during this hot weather, is absolutely vital; if you’re feeling thirsty, chances are you are already dehydrated. Dehydration can seriously affect exercise performance and if you don’t commence exercising hydrated and fail to rehydrate between workouts, you are not going to realise the results you would be hoping to achieve. Plain water is often not ideal as it won’t replace the electrolytes, namely sodium, lost through sweat and in extreme cases can cause hyponatremia (low plasma sodium levels). Our bodies are extremely clever in trying to manage this state; the kidneys will try to conserve both water and electrolytes but the only way the deficit can be restored is through fluid intake.
It is often
recommended to weigh yourself before and after exercise to ascertain fluid lost
through sweating; however only replacing what has been lost will not result in
effective rehydration; post-exercise the amount of fluid must be greater in
order to achieve euhydration (being in water balance).
If your blood is 85% water, just think how much harder it is for your heart to pump thick & sticky blood around your body!
Stay well hydrated, Cathy x
