The body tightly regulates its water content to take care of optimal levels of Total body water and “osmolality”—the concentration of dissolved particles in your blood. Osmolality increases when you're dehydrated and reduces when you might have an excessive amount of fluid in your blood.

Osmolality is monitored by osmoreceptors which regulates sodium and water balance within the hypothalamus – the a part of the brain that controls many hormones. These osmoreceptors signal the discharge of antidiuretic hormone (ADH), which acts on the blood vessels and kidneys to control the quantity of water and salt within the body.

In healthy people, the body releases ADH when osmolality becomes high. ADH tells the kidneys to reabsorb water, which makes the urine more concentrated. Reabsorbed water thins the blood, bringing the osmolality back to normal levels.

Low blood volume inhibits the discharge of ADH, reducing the quantity of water reabsorbed by the kidneys. This dilutes your urine, which the body then passes on to rid itself of excess water.

Healthy urine ought to be clear and odorless. Dark, yellow urine with a noticeable odor may indicate dehydration—although medications and certain foods, including Insulation whiteIt can even affect the colour and smell of urine.
