Our body is composed of 70% of water. Interruption of liquid intake or its excessive removal from the body by sweating, diarrhoea, vomiting, or increased physical exertion leads to dehydration, which can end up with the death of the person.
Dehydration is dangerous in any season, but during the summer, due to high temperatures and more abundant sweat, the risk is much higher. Moreover, don`t forget about increased incidence of food toxicoinfection and diarrheal diseases, leading to additional losses of fluid and mineral salts.
What are the common symptoms of dehydration of the body?
1. Feeling tired – water is the main source of energy.
2. Muscle cramps – involuntary contractions of muscle groups occur, being caused by the loss of mineral salts through sweating.
3. Headaches – because the brain is not fed up by the circulatory system with enough water for its normal operation. First response sent by the brain is dilatation of blood vessels, i.e. you will notice the redness of facial skin.
4. Dark coloured urine, lack of urination – which affects the urinary system.
Also the lack of liquids may cause: depression, restless sleep, nervousness, stress, lack of attention, nausea etc.
You should also know that through perspiration you not only lose liquids, but also all of the trace elements in the body. With their loss there occurs a hemoconcentration in the blood (the blood becomes viscous as a result of the loss of liquid and micronutrients). If you do not intervene with water intake, in particular, for individuals who suffer from cardiovascular diseases, hemoconcentration leads to complications such as thrombosis, heart attack, and vascular accidents.
You must know that dehydration is dangerous for anyone, but for children and the elderly it can be lethal.
Be careful to your baby, if it experiences symptoms such as vomiting, diarrhoea (often encountered), in addition to the treatment prescribed by the doctor, it is important to increase the fluid intake.
