With a better claim than ordinary water, are now various types of bottled drinking water invaded the market. There are water fortified with vitamins, isotonic drinks, energy drinks, to drink beverages oxygenated or hexagonal.
People who consume these drinks also claim to feel more fit, not easily tired and more concentrated.
Responding to these trends berfortifikasi drinks, dr.Parlindungan Siregar, Sp.PD-KGH, Division of Renal Hypertension FKUI / RSCM assess the actual water that we consume daily is enough to replace the fluid that comes out with dried and urine.
"The benefits of drinking water is added it actually has not been proven scientifically. It may not sound even harmful if consumed in vain," said dr.Parlin.
Oxygenated water for example, according to oxygen can not be absorbed in the intestine. "Humans get oxygen through the lungs, not through gills like fish, so that oxygenated drinks will not affect oxygen levels in human blood," he said.
Basically, all drinking water contains dissolved oxygen, but the size depends on water temperature, total solids and water resources. Water that comes from the cold mountains contain more oxygen, so it felt more fresh when drunk.
A study of one brand of oxygenated drinking water also showed, after it is opened for 3 days, the original oxygen content of 120 ppm down to 80 ppm. That means the water oxygenated or hexagonal water was finally turned into a regular drinking water.
"The stability of oxygen levels in water temperature is very rendan and holds an important factor. The higher the temperature, it is probable that the oxygen in water decreases," said dr.Samuel Oetoro Sp.GK, as quoted tabloid edition of the Healthy Lifestyles 603 in 2011.
Meanwhile, isotonic drinks really should not be taken arbitrarily because basically isotonic saline. If excessive levels of salt in the body will cause high blood pressure or hypertension.
Beverages in containers are also mostly high in calories so it can cause obesity. Because it is more advisable to consume water when we're thirsty.
"So thirsty should immediately drink because thirst is a signal from the body if we have started to mild dehydration. If ignored it can interfere with cognitive abilities so that we can lose concentration or sleepy," said dr.Saptawati Bardosono, Sp.GK.
