Urine is normally pale yellow or white, is clear, and is usually colorless and transparent. When the body drinks a lot of water, the urine is colorless and clear. When drinking less water, or when the ambient temperature is high, or when you have a fever or are anxious and on fire, the urine becomes concentrated and the urine becomes yellow. If the urine is obviously yellow, it means that you drink too little water, or there is also a possibility of urinary tract infection. You must drink more water to increase the volume of urine, and the urine will return to its normal color and the urinary tract infection will be significantly relieved. The color of urine is also related to the food and medications consumed. Many foods are yellow or red, and medications may have yellow, red, green, purple, etc. These pigments may cause the urine to appear in the corresponding color after intake.
