Why do people have dark circles, thank you

Black eye circles are caused by staying up late, emotional instability, eye fatigue, aging, slow blood flow in the veins, insufficient oxygen supply to the red blood cells in the eyes, excessive accumulation of carbon dioxide and metabolic wastes in the veins, the formation of chronic hypoxia, dark blood and stagnation of the blood, and the pigmentation of the eyes.

Dark circles are also what we often call "panda eyes", which are due to frequent staying up late, emotional instability, eye fatigue, aging, slow blood flow in the veins, insufficient oxygen supply to the red blood cells in the eyes, excessive accumulation of carbon dioxide and metabolic wastes in the veins, the formation of chronic hypoxia, dark blood and the formation of stagnation and eye pigmentation. The older you get, the thinner the subcutaneous fat around your eyes becomes, so dark circles are more noticeable. There are actually two colors of dark circles, one is cyan dark circles, which is due to the retention of venous blood in the microvessels; The other is brown dark circles, which are caused by incomplete melanin production and metabolism, and the causes of dark circles are completely different.

Blue and black eye circles usually occur around the age of 20, and it is especially difficult to avoid people with abnormal lifestyles. Nowadays, due to the high pressure of students to study, it has become common for young people to stay up late, so the age of people with dark circles has a downward trend, and dark circles are already common among people over 18 years old. It is the result of a large increase in hypoxic heme due to the slow blood flow rate in the microvessels, the increase in blood volume and the increase in oxygen consumption.

From the outside, ** appears in a dark blue hue. Due to the large number of microvessels around the eyes, lack of sleep, eye fatigue, stress, anemia and other factors can cause bruising and puffiness of the skin around the eyes. The cause of black eye circles is closely related to aging, long-term sun exposure causes pigmentation around the eyes, and over time it will form lingering dark circles;

The formation of dark circles is related to the following factors:

1.Genetic constitution and physiological structure, when the ** around the orbit is particularly thin, and the subcutaneous tissue is very small, when the blood flow through the large veins here, it is convenient to appear blue-black halo under the surface layer of the **, which is called dark circles.

2.Lack of sleep and excessive fatigue make the eyelids unable to rest, in a state of tension contraction, the blood flow in this area increases for a long time, causing the subcutaneous tissue of the eye circle to fill with blood vessels, which leads to congestion of the eye circle and leaves a dark shadow.

3.The loss of kidney qi makes the eyes lack the moisture of essence, causing the black to float on top, so the eye circles are black.

4.People who have been sick for a long time and are weak or have just recovered from a serious illness, due to the weak subcutaneous tissue around the eyes, are prone to pigmentation, and are easily exposed on the upper and lower eyelids, and a layer of black circles appears.

5.Women with irregular menstruation, functional uterine bleeding, primary dysmenorrhea, early menstruation, wrong menstruation, excessive menstruation, excessive menstrual flow, late pregnancy, old age, etc., dark circles will also deepen day by day, and other factors include genetics, excessive use of cosmetics, which makes pigment particles penetrate, and excessive intercourse, which will lead to dark circles.

People will have dark circles when they don't get enough sleep or stay up late, it is best to maintain adequate sleep, keep about 10 hours of sleep for minors, and 6 to 8 hours of sleep for adults. Hope.

Dark circles are very common, so don't be nervous. For boys, the formation of dark circles is related to sleep time and sleep quality, and boys are also prone to dark circles if they are in front of the computer for a long time. If you have big eyes, you should pay more attention to it, dark circles will be more obvious.
