The heat inside the body or turbid qi spoken of in Donguibogam are complex signals from our body that can be fully explained by modern medicine as well. In particular, changes in urine color or frequent urinary tract infections are strong evidence that red lights have turned on in our body's crucial fluid metabolism and immune system.
Our kidneys are vital organs that filter about 180 liters of blood every day to remove waste and regulate fluid and electrolyte balance in the body. Urine is a mixture of waste and water discharged from the body through this process. If fluid intake becomes insufficient, the kidneys attempt to maximize the reabsorption of water to maintain homeostasis. In this process, urine becomes far more concentrated than usual, and the concentration of a pigment called urobilinogen increases, resulting in a dark yellow or orange color. This is one of the most direct warning signs that the body has entered a state of dehydration.
Furthermore, chronic dehydration can become the main culprit of urinary tract infections, namely cystitis. Urine is not simply a liquid carrying waste; it also acts as a cleaner that physically washes away bacteria within the urinary system. When urine volume decreases and becomes concentrated, bacteria entering the urinary system are not washed away adequately, creating an environment where they easily adhere to the bladder wall and proliferate. Particularly in women, the urethra is shorter, making it easier for bacteria to travel to the urinary bladder, which makes them more vulnerable to urinary tract infections than men. If urinary retention is prolonged at this time, bacteria proliferate even more actively, which ultimately leads to an inflammatory response of the bladder mucosa, causing unpleasant symptoms such as pain, frequent urination, and a sensation of residual urine.
Urinary tract infections go beyond mere discomfort; if left untreated, they can worsen into more serious kidney diseases such as pyelonephritis. In addition, according to studies, a chronic inflammatory state also contributes to decreased immunity and negatively affects systemic health. Therefore, instead of taking dark urine lightly, it is very important to consistently care for the urinary system through sufficient fluid intake. Beyond simply quenching thirst, this becomes a key strategy to optimize kidney function, suppress bacterial proliferation, and keep our body's most basic immune defense line strong. Water is essential for all cellular activities and metabolism processes in our body, and is the most indispensable element for sustaining life, including thermoregulation, nutrient transport, and waste removal. Clear urine is a positive sign that our body is circulating healthily, so simply forming a habit of checking your urine color every day allows you to easily understand your body's health status.
