Fluid circulates in vessels, fills various cells and stays between cells. It is involved in numerous processes that help us stay healthy and active.
-We lose water throughout the day, vaporizing it when we breathe, cry and sweat. Our bodies eliminate water through urine and feces. In addition to fluids, certain amounts of electrolytes are also eliminated from the body.
-To maintain normal functioning, the body tries to adjust water intake to water losses.
-We replenish body fluids by drinking beverages and eating water-rich foods.
-However, sometimes we fail to meet our water needs because we are too busy, are sick to have a drink, or do not have safe drinking water resources available (in travel, camps, etc.):
-When the body loses more fluids than it takes in, it is called dehydration.
-It can occur for numerous reasons, from reduced sense of thirst (in the elderly) to high fever, profuse diarrhea, severe vomiting, and increased urination (in those living with high blood glucose levels or taking water pills).
In most cases, the body sends out warning signals to signal a lack of water before serious health problems begin to develop. What are these warning signals?
-Dehydration can trigger a migraine attack, especially if you are predisposed to this type of headache. This is why painful sensations in the head can be relieved after drinking a glass of water.
-Inadequate water intake can reduce the production of saliva, which normally moisturizes the mouth. This causes unpleasant sensations in the mouth and bad breath.
CHANGES IN URINE
-When not drinking enough, the body tries to “save” water by reducing the amount of urine. In addition, urine becomes very concentrated and turns more yellow than normal.
-It is common for dehydration to make people feel sleepy all the time, even after a restful sleep.
-With fluids, salts and electrolytes are lost. If these losses are not corrected, the body’s electrolyte balance can be disturbed, sometimes causing muscle cramps in the limbs.
-Vizziness and dizziness can be due to numerous reasons. Lack of water is one of them.
-When you are dehydrated, you may feel dramatically exhausted, even if you have not engaged in strenuous physical activity.
INCREASED HEART RATE
-In more advanced cases, dehydration causes the heart to beat too fast to compensate for the drop in blood pressure that occurs due to severe fluid loss.
