Human Body and Water
Muscle tissues in the human body contain more water than fat tissues.
2/3 of the water in our body is inside the cells, the rest is in the vessels, between the tissues, in the digestive system and in the body cavities.
Most of the body fluids (blood, gastric secretion, saliva, amniotic fluid formed during pregnancy, urine), which have many vital functions, are water.
Water is taken into the body through foods and beverages, and the water is absorbed into the bloodstream after being absorbed in the digestive system. The water dispersed throughout the body by the blood circulation leaves the capillaries and forms the tissue fluid. Water, which participates in some chemical reactions in the cell, goes out of the cell again, turns into tissue fluid and participates in the blood circulation through the tissues. Most of the water coming to the kidneys through the blood circulation is excreted out of the body as urine. Some of it is excreted from the body by using the skin, respiratory and digestive systems.
Water retention in the body is provided by the hormone called vasopressin. The brain regulates water retention in the body with the vasopress hormone synthesized in the hypothalamus. Sensory and stimulating cells that create the feeling of decreased water in the body and thirst are also found in the brain part of the body.
The Importance and Functions of Water in the Body
- Water provides the protection of the brain, spinal cord and other organs from external factors.
- It moisturizes the mouth, nose and eye tissues. The air in the lungs is moistened with the help of water in the body, which helps breathing.
- Water ensures that the body temperature is kept in balance. Adequate water consumption per day accelerates metabolism.
- Water plays an important role in digesting food and converting it into energy.
- Water helps to remove waste and toxic substances from the body.
- Blood volume and pressure are balanced with water. Water provides the fluidity of the blood in the body.
- By carrying water, oxygen and nutrients to the cells, it ensures the dissolution of the solid substances necessary for the cells to perform their functions in a healthy way.
- The balance of the muscles and the lubricity of the joints are provided by water.
- Water plays an important role in the removal of edema in the body.
Daily Water Consumption and Body Balance
The daily water requirement of an adult is approximately 2500 ml. However, this amount constitutes the need that should be consumed only as water. Since some of the liquid drinks such as tea, coffee, fruit juice can increase the removal of water from the body, it is necessary to pay attention to the consumption of only water.
In the body, the intake and removal of water from the body is carried out in a certain balance. Basically, the normal volume of fluid in the body is in question, and the water consumed daily must maintain the volume of fluid in the body.
In order to maintain the fluid volume in the body, daily fluid intake must be equal to daily fluid loss. In case of deterioration of this basic fluid balance in the body, some discomforts occur.
In case of consuming sufficient amount and quality of water for the body, most of the trace elements that the body needs can be met. This is reflected in the body as the beautification of the skin and the strengthening of the immune system. Through adequate and qualified water consumption; The risk of colds, urinary tract infections, kidney stones and bladder cancer is reduced.
Situations That May Occur If Adequate Water Consumption Is Not Provided
Signs of Mild and Moderate Water Deficiency
- Dryness in the mouth and mucous membranes
- Decreased urine output
- muscle weakness
- Headache or, in some cases, dizziness
- Weakness in short and long-term memory
- weakening of perception
- somnolence, light-headedness and tiredness
- State of weakening of arithmetic ability
- orthostatic hypotension
- Decreased eye age
Severe Water Deficiency Findings
- extreme thirst
- Excessive drying of the mouth, skin and mucous membranes
- Decreased sweating
- Dark yellow or amber urine
- Little or no urination
- Collapse of the eyeballs
- Loss of consciousness
As a result of excessive deterioration of the water balance in the body; It can cause confusion, arrhythmia, delirium, decreased turgor tone.
