Water is as precious as the air that
you breathe; you cannot live without it! It is one of the most important
components of all living organisms. Although you will be able to live without
food for up to 50 days, without water you will barely survive for a few days ,
even in a cool climate. Water cannot be stored in the human body; therefore the
amount of water lost everyday must be replaced to maintain your overall health
and body functions. Your body loses water primarily through urine, sweat,
exhaling, feces and perspiration and the two main sources to replace the water
lost from your body is - food and beverages.
Why do you get dehydrated?
Any condition that
increases your body temperature like physical activity, fever or high external
temperature increases the need for water. So, dehydration is mainly caused by the
inadequate intake of water or excessive fluid loss – in this case the hot
summer days.
What are the symptoms of dehydration?
Although
thirst encourages you to drink water, once you feel thirsty it means that
dehydration has already occurred to a certain degree. Mild dehydration may result
in tiredness, headache and decreased alertness and ability to concentrate.
Other physical consequences may vary from a dry mouth and dark coloured urine
to tingling and numbness.
Prevent getting dehydrated by using these methods
Your
can maintain an appropriate water intake to match your body fluid loss and thus
prevent dehydration. As mentioned earlier, the onset of the sensation of thirst
is already a sign that dehydration has started. It is therefore good practice
to anticipate and drink before becoming thirsty. A suitable daily allowance for
adults is an average of 2.5 litres of water of which about 1.5 litres (8
glasses) should be consumed by drinking water and other liquids.
Good to Remember:
Keep yourself well
hydrated throughout the day as this helps in maintaining concentration and
alertness!
