Water is essential for the human body, with functions such as regulating body temperature, transporting nutrients, and eliminating waste. The body is made up of 55-65% water, and newborns have even more. Osmoreceptors in the brain monitor the body's water balance by detecting the concentration of particles in fluids. When we lose water, osmoreceptors shrink and signal thirst, while an excess of water results in less thirst. Dehydration can lead to kidney strain, brain shrinkage, and cognitive impairment. The cardiovascular system is affected as blood thickens when dehydrated, resulting in increased heart rate. Overhydration can lead to hyponatremia, which dilutes sodium levels in the blood and can be dangerous. Recommended daily water intake is 3.7 liters for men and 2.7 liters for women, but individual needs vary depending on factors like climate and activity level.
