vízegyensúlya

Vízegyensúlya refers to the balance of water within the human body. This balance is crucial for maintaining physiological functions. Water constitutes a significant portion of the body's mass and is involved in numerous processes, including nutrient transport, temperature regulation, waste removal, and cellular activity.

The body obtains water through drinking fluids and consuming food, and loses it through urine, feces, sweat, and respiration. When water intake and output are equal, the body is in a state of euhydration. Disruptions to this balance can lead to dehydration, where water loss exceeds intake, or overhydration, where intake significantly surpasses the body's ability to excrete it.

Several factors influence vízegyensúlya, including environmental conditions like temperature and humidity, physical activity levels, diet, and certain medical conditions. Hormones, such as antidiuretic hormone (ADH) and aldosterone, play a key role in regulating water reabsorption and excretion by the kidneys, thereby helping to maintain fluid balance. Thirst is a primary sensation that signals the need for water intake. Proper vízegyensúlya is essential for overall health and well-being.
