EWT Summer tips
Be water-wise when
it comes to using water this summer by having a read of our summer tips.
Water
belongs in your workout
Finally! The weather is
warm, the sun is shining, and you’re lacing up your athletic shoes and
ready to go.
Wait a minute … have you
had a drink of water?
If you’re exercising
moderately, The American College of Sports Medicine recommends drinking:
 |
240 to 300 ml of
water before exercise. |
 |
90 to 120 ml of
water every 10 to 15 minutes while exercising. |
 |
240 ml of fluids
after exercising. |
On average, your body
loses approximately 2.3 litres of water daily. When you exercise, your
body produces internal heat that is released and cooled through
perspiration. This process accelerates water loss. You lose water faster
than salt and carbohydrates, so healthy water is the best fluid to drink
for the first 80 minutes of your workout. If you’re exercising longer, a
sports drink with 4 to 8 percent carbohydrates will help replace lost
minerals.
Dangers of Dehydration
Don’t rely on thirst to
be your guide. You can lose 2 to 3 percent of your body fluid before
your mouth feels dry. By the time you take a drink, you’re no longer
exercising at peak physical performance.
Ignoring your body’s need
for water can be dangerous, especially in heat. Warning symptoms of
dehydration include light-headedness, headache, fatigue, muscle cramps
and confusion. Cardiac failure and coma can result from severe heat
exhaustion,
So take a drink of cool,
refreshing water and carry a filled water bottle with you before you
head out the door.
Pool
Cues - Tips to keep your hair cool after the pool
Swimming is as much a
part of summer as barbecues and cricket. While swimming is excellent
exercise, it’s also very tough on your hair.
You may be surprised to
learn that it’s not the chlorine in the pool water that turns blond or
grey hair green. The culprits are actually hard metals dissolved in the
water, particularly iron, manganese or copper that leaches out from pool
pipes. The hair shaft absorbs the metals, which are oxidized by
chlorine, turning hair a greenish colour.
If your want to avoid
"green" hair, try the following:
 |
Immediately after your swim, wash your
hair in warm, softened water. |
 |
Use a shampoo containing EDTA (ethylenediamene
tetracetic acid) or dissolve an aspirin in warm water and wash
your hair with the mixture to reduce the build-up of oxidized
metals in your hair. |
While chlorine may not
turn your hair green, it causes plenty of damage. A bleach, chlorine
will fade colour-treated hair, cause the frizzies in permed hair, and
leave dark hair dull and lifeless. Chlorine dries all hair types,
causing breakage. To prevent damage, wear a leave-in conditioner while
swimming. Covering your hair with a latex or silicone bathing cap while
you exercise will give you a heat-conditioning treatment.
After swimming, you can
minimize chlorine damage by:
Even if you don’t swim,
summer can be tough on your hair. Your skin isn’t the only thing that
can get sunburned. So protect your hair with a SPF conditioner, wear a
hat when you’re out in the sun and make sure you wash your hair in soft
water. Hard water mineral residues quickly build upon the hair shaft,
causing dull, rough hair. Soft water and a good shampoo and conditioner
will help restore soft, shiny hair.

Ice - What's the deal with cloudy cubes?
Your water looks clear
when it comes out of the tap, so why do your ice cubes look like frozen
skim milk? Well, there isn’t one clear answer. Making crystal-clear ice
cubes depends upon several factors:
 |
Highly filtered water — Hard water
contains minerals like calcium that condense when frozen, which
will cloud up ice cubes. Installing a water conditioner will
remove many of the minerals that cause hard water, but minerals
aren’t the only culprits in forming cloudy ice cubes. |
 |
Dissolved air — As water freezes,
dissolved air is forced out as a gas, which forms bubbles. These
bubbles are trapped in the ice, making it look opaque. Even
distilled water or water filtered through a reverse osmosis system
needs to be boiled to remove dissolved air before it is frozen.
But this still doesn’t guarantee clear cubes. Even after boiling,
the ice may still have bubbles because of the freezing process.
|
 |
Freezing in layers — Pristine icicles
are created when water drips down and freezes in progressive
layers. This prevents air bubbles from forming. The same idea is
used in commercial ice machines — cold water flows continuously
over a grid where ice forms in layers. This process freezes a
fraction of water while the rest is discarded before the air
concentration gets too high. An ice cube tray in the freezer can’t
replicate this effect, although making your cubes smaller or
thinner may help. |
The ice you make at home
will never look as clear as the kind you buy from a commercial ice
manufacturer. But there are some simple things you can do that may make
your ice look better:
 |
Use softened water filtered by a reverse
osmosis system. |
 |
Use warm water, which
contains less dissolved gas. |
 |
Reduce the
temperature of your freezer so the ice forms more slowly, reducing
the problem of dissolved air bubbles. |
