Your body’s water balance is determined by how much you consume, your age and activity level and environmental conditions. The human body is roughly 75 percent water. Without this water, it cannot survive. Water is found inside cells, within blood vessels, and between cells.
Although water is constantly lost throughout the day as we sweat, breath and elimination of waste, both liquid and solid. We can replenish the water in our body by drinking fluids.
The body can move water around to areas where it is needed most if dehydration begins to occur. Water transports nutrients, regulates body temperature, lubricates joints and internal organs, supports the structure of cells and tissues and preserves cardiovascular function. People can survive for only three or four days a week at most without water
Inadequate hydration can cause fatigue, poor appetite, heat intolerance, dizziness, constipation, kidney stones and a dangerous drop in blood pressure. In most incidents of low hydration it can easily be solved by our thirst mechanism telling the body when it needs to increase fluid intake but in severe cases it require immediate medical attention.
