Human body suffers from water crisis as years go by
The human body is 90% water at birth. The water content in the body of a
grown-up person decreases to 70%. The water content drops to 50% with age. So
it must be water that keeps humans alive. Man depends on the quality of water
in terms of physical and psychological state of his body. The latest studies
show that water can have either beneficial or detrimental impact on the body.
Lev Skvortsov, an academician of the Russian Academy of Natural Sciences,
doctor of technical sciences, a member of the Russian Ministry of Health
consultative council on drinking water issues, shared his views on how humans
should treat water
Lev Skvortsov started the conversation by extolling water.
- Water regulates the temperature of the body, it humidifies the air we
breathe, it helps organs assimilate the nutrients and expel the toxins and
excess salts. Water helps keep the blood pressure down, thus reducing the
probability of a heart attack. The above "job description" for the water is not
by any means complete. It's just amazing that water can help you when you're
down in the mouth. Water can wash away the negative energy that builds up in
your system during the day. That's why I strongly recommend that you go to a
swimming pool regularly, and take a shower right after you come home from work.
Take a hot bath before going to bed. You'd better form a habit of showering
every time you have a headache or one of those days. I'm sure water can help
you out.
- Scientists are still arguing how much water a person should drink. The
numbers range from 1,5 to 4 liters for a recommended daily amount.
- The body of a healthy individual can use up to 2-3 liters a day. This
amount should be replenished, otherwise digestion and blood formation will be
disrupted. You should drink at least 2 liters more if temperatures rise
outside. Those who are engaged in sports, undergo treatment, or take vitamins
should increase their daily intake of water. By the way, you shouldn't drink
water in a large swallow. Drink it slowly, pause for several seconds before
swallowing.
- How can you tell that your body isn't getting enough water?
- During dehydration the skin gets dry, a person grows tired quicker than
usual and finds it hard to concentrate. Other signs include headache,
constipation, hypertension, allergic reactions, the kidneys don't work well.
The symptoms of a lack of water also include a recurrent infection of the
genitourinary system, dry cough, pain in the back and joints.
- Can you replenish the loss of water by drinking lots of soda pop or
juice?
- Juice contains vitamins and calories, it's rather a kind of food. Juice
can't be considered when it comes to water supply of the body. Therefore, you
shouldn't drink fruit juices to excess. The large amount of distilled water is
bad for your health too because both bacteria and beneficial microelements have
been removed from it. Distilled water is aggressive water. It has an increased
solvent action. Drinking distilled water for a long time will result in the
loss of mineral salts and cause damage to cardiovascular and bone system of
your body. You'd better drink ordinary water.
- Most Russians are unhappy about the taste and smell of tap water these
days.
- No doubt about it, today's tap water flowing through the municipal
water supply system leaves much to be desired. It contains dissolved iron and
manganese, calcium salts and magnesium that lead to wear and tear of the
plumbing equipment and bathroom accessories. The water does damage to the human
body too. On the one hand, chlorine (added in water) kills most dangerous
microbes. On the other hand, it is one of the causes of atherosclerosis.
Besides, chlorine forms carcinogenic substances when it mixes with organic
matter present in water. By the bye, it is very difficult to determine the
quality of water by looking at a water sample with the naked eye. The majority
of harmful impurities are odorless and taste-free.
