Fluid circulates in blood vessels, fills various cells and is found between them. It is involved in many processes that help us stay active and healthy.
-During the day, we lose water by evaporating it through breathing, crying and sweating. Our bodies excrete water through urine and feces. In addition to fluids, the body also excretes a certain amount of electrolytes.
-In order to maintain normal function, the body attempts to regulate water intake based on water loss.
We replenish body fluids by drinking beverages and eating water-rich foods.
-But sometimes we can’t meet our water needs because we are too busy, too sick to drink, or don’t have access to safe sources of drinking water (travel, hiking, etc.) :
-When the body loses more fluid than it takes in, it is called dehydration.
-This can occur for a variety of reasons, from a decreased sense of thirst (in the elderly) to high fever, profuse diarrhea, severe vomiting and rapid urination (in people with high blood sugar or who take water pills).
In most cases, the body sends warning signals about water shortage before serious health problems begin to develop. What are those warning signs?
HEADACHES.
-Dehydration can trigger a migraine attack, especially if you are prone to this type of headache. Therefore, you can relieve a headache by drinking a glass of water.
DRY THROAT.
-Insufficient water intake can reduce the production of saliva, which normally moisturizes the mouth. This causes discomfort in the mouth and bad breath.
CHANGES IN URINE
-Insufficient water intake causes the body to try to “conserve” water by reducing the amount of urine. In addition, the urine becomes very concentrated and takes on a more yellow color than usual.
DEHYDRATION
-In general, in cases of dehydration, people feel constantly drowsy, even after a good night’s sleep.
MUSCLE SPASMS.
-With fluids, salts and electrolytes are lost. If these losses are not replenished, the body’s electrolyte balance can become unbalanced, sometimes causing muscle cramps in the extremities.
VERTIGINE
-Headaches and dizziness can be caused by many things. Lack of water is one of them.
SEVERE FATIGUE.
-If you are dehydrated, you may feel very tired, even if you have not been doing strenuous physical activity.
INCREASED HEART RATE.
-In the most severe cases, dehydration causes your heart to beat too fast to compensate for the drop in blood pressure due to a significant loss of fluid.
