Why is my urine yellow in the morning?

Many people find that their urine is very yellow when they wake up in the morning, but they don’t know what’s going on. Generally speaking, yellow urine in the morning may be normal, that is, physiological yellowing. It may also be pathological yellowing, that is, yellow urine is related to some diseases.

1. Regarding the color of urine

Urine is mostly water, with only a small amount of solutes. Among these solutes is a component called urochrome, a yellow substance produced by the kidneys that dyes the urine yellow. The color of urine is not constant. The color of urine is sometimes yellowish brown, sometimes light yellow, and sometimes almost colorless. The color of urine changes with the amount of water the body drinks every day, the amount of sweat produced, etc. Because the amount of urochrome produced by the kidneys every day is roughly constant, if you drink more water or eat foods that are high in water, such as fruits, your urine volume will increase, the urochrome will be diluted, and the color of the urine will become lighter. If you sweat a lot or drink little water, your urine volume will decrease, and the urine will be concentrated and dark yellow. There is no need to worry too much about this situation. As long as the water in the body is replenished in time, the urine will still return to its original color. If you still feel that your urine is abnormal, you can go to the hospital for a routine urine test.

2. Urine Concentration

Yellow urine is a symptom caused by the concentration of urine during the first urination in the morning. The human body is still metabolizing at night, but urination does not occur for a long time at night, so the urine is more concentrated than during the day, causing the yellow urine.

3. Getting angry

Yellow urine is probably caused by getting too hot. The symptoms are mainly caused by the downward movement of heart fire. It is mostly related to improper diet and lack of water. In this case, you should eat more light foods, such as bitter gourd, cucumber, tomato, etc., drink more water, or drink some green tea. You can also drink water soaked with light bamboo leaves, which can relieve heat and promote urination. Do not eat spicy food and avoid fatigue.
