You probably know that our bodies are made up of 75% water.
The fluid circulates in the vessels, fills the different cells, and remains between the cells. It is involved in many processes, which help us stay healthy and active.
- We lose water throughout the day, we evaporate it when we breathe, cry and sweat. Our body gets rid of water through urine and feces. Along with fluids, certain amounts of electrolytes are also removed from the body.
To maintain normal functioning, your body tries to adapt water intake to water loss.
- Replenish body fluids, drink beverages and eat foods rich in water.
- But sometimes we fail to meet the water needs, because we are too busy or sick and don’t have a cup of drink or we don’t have a safe supply of drinking water (on trips, camping, etc.):
When your body loses more fluids than you take in, it is medically called dehydration.
- It may occur for many reasons, from a decreased sense of thirst (in the elderly) to high fever, profuse diarrhoea, severe vomiting and increased urination (in those who live with high blood sugar levels or take water tablets).
In most cases, your body will send warning signs that it is lacking in water, before serious health problems begin to appear. What are these warning signs?
Dehydration may trigger a migraine attack, especially if you are prone to this type of headache. That is why the painful sensations in the head may disappear after drinking a glass of plain water.
Inadequate water intake may reduce saliva production, which normally moistens your mouth. This causes unpleasant sensations in the mouth and bad breath.
changes in urine
- When you don’t drink enough, your body tries to “save” water, reducing urine output. Moreover, this urine becomes very concentrated which makes it more yellow than usual.
It is commonly believed that dehydration makes people feel drowsy all the time, even after a restful night’s sleep.
- You lose salts and electrolytes with fluids, you know. If these losses remain uncorrected, the electrolyte balance may be disturbed in the organism sometimes resulting in muscle cramps in the extremities.
You may feel dizzy and dizzy for many reasons. And the lack of water is one of them.
When you become dehydrated, you may feel very tired, even if you are not engaging in vigorous physical activities.
Increased heart rate
In advanced cases, dehydration causes the heart to beat very quickly to compensate for the drop in blood pressure that occurs due to severe fluid loss.
