Why do I still have dark circles under my eyes and swollen eyes even though I have slept a lot?

As the upstairs said, sleep is about quality, not time. Human sleep can be divided into two types of periods, according to the form of EEG, divided into slow-wave sleep and fast-wave sleep, the two types of sleep alternately, the average person first enters the slow wave when they start to fall asleep, then turns into the fast wave, then enters the fast wave, and then enters the slow wave, and then the slow wave, before waking up is the slow wave. Among the two types of sleep, the one that really achieves effective rest is fast-wave sleep, during which all organs of the body are in a state of complete relaxation, and various repairs and accumulations are also completed at this time; The nerve cells of the brain are still active during slow-wave sleep, and people's dreams are also a product of this period, and other systems are likely to not get enough rest under the command of active nerve cells.

Therefore, whether the sleep is good or not, an intuitive criterion is whether there are many dreams, and the dream is not enough, and the dream is not enough, even if the total sleep length is very long, but the effective sleep is not much, and the overall feeling of sleepiness and fatigue will still be felt.

Sleep isn't about the length of time, it's about the quality. If the quality of sleep is high, and organs such as the brain and eyes are fully rested, it is generally enough to ensure about 7 hours a day. If you sleep for too long but have dreams or babble, your brain is not resting well.

It does not mean that you have slept well, so even if it is a long time, it does not mean that you will rest well, and your eyes or other organs do not react to the face such as dark circles.

It may be that the lack of powder, iron and vitamin C will lead to the appearance of dark circles, so you should consume more nutrients in this area, such as noodles, pork liver, spinach, tomatoes and other foods. Drink plenty of water to effectively remove waste from the body, reduce the chance of accumulation, and reduce dark circles, preferably 8 cups a day. Drinking a glass of jujube water every day can help speed up the flow of blood qi, reduce the accumulation of blood stasis, and reduce the chance of dark circles under the eyes due to anemia.

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.

Because it's obviously a giant panda.

Yoghurt**.

After each yogurt, pour the remaining little over the gauze, apply the gauze with yogurt to the eyes for 10 minutes, and then rinse off with water. Or put the yogurt in the refrigerator for more than ten minutes before taking it out, and then wipe the eye area with a cotton pad for 15 minutes.

Hard-boiled eggs**.

Peel the hard-boiled eggs, wrap them in a towel, place them around the eyes, and gently roll and massage. This method improves dark circles by speeding up blood circulation while also eliminating eye bags.

Apple**. Cut the fresh and juicy apple into slices, apply two slices to the eyes, and wash after 15 minutes.

Potato**. Similar to apples**, take two slices of cut potatoes and apply them to your eyes, not too thick, about 2mm. Remove and wash after 15 minutes.

Eye-to-tear trough type: Changes in the structure around the eyes, forming shadows, can cause eye-bag-trough dark circles. Sagging, muscle relaxation, changes in fat mass, protruding eye bags, and sagging tear troughs around the eyes can cause structural changes around the eyes, resulting in dark circles.

Pigmented dark circles: Pigmented dark circles are formed when excessive melanin deposition around the eyes causes darkening. Sun exposure, inflammation and damage around the eyes, pigmented nevi around the orbits, etc., can lead to pigmentation around the eyes, resulting in dark circles.

Vascular type: The lower eyelids are very thin, and the blood vessels reveal blue through the thin eyelids**, forming a dull feeling around the eyes, which is vascular dark circles. If the local blood circulation under the eyelids is not good, and the hemoglobin in the blood is increased, it will appear blue and purple, and dark circles will also be formed.

Most of the causes are born dark circles, staying up late, overusing eyes, rhinitis, and aging.

Dark circles are a complex eye cosmetic problem used to describe the dullness around the eyes. Dark circles can be caused by a variety of factors. According to its **, it can be divided into three categories: pigmented dark circles, vascular dark circles, and structural dark circles.

The first point is that there are dark circles under the eyes, the second point may be caused by staying up late, and the third point may be that you have a disease in your own eyes, so you will have dark circles.

Getting enough sleep and dark circles under your eyes is likely to be caused by endocrine disorders.

In addition to staying up late, dark circles may also be due to mood swings, eye fatigue, and aging, resulting in the blood flow speed of the blood vessels in the eyes being too slow to form stagnation; Insufficient oxygen supply to tissues leads to excessive accumulation of metabolic waste products in blood vessels, resulting in ocular pigmentation. The older you get, the thinner the subcutaneous fat around your eyes becomes, so dark circles are more noticeable.

There are several causes of dark circles, such as:

1. Genetic constitution and physiological structure.

When the ** around the eye socket is particularly thin and the subcutaneous tissue is very small, when the blood flow through the large veins here, it is convenient for blue-black halo to appear under the surface layer of the ** very close, which looks the same as the dark circles.

2. Lack of sleep.

There are many microvessels around the eyes, staying up late makes the eyelids not rest, the blood vessels continue to tense and constrict, and the blood flow increases for a long time, causing blood vessel congestion and edema in the subcutaneous tissues of the eye circle, leaving a dark shadow.

3. Long-term illness and frailty or initial recovery from serious illness.

Due to the weak subcutaneous tissue around the eyes, it is easy to develop pigmentation, and it is very easy to appear on the upper and lower eyelids, and a layer of black circles appears.

4. Inflammation. Hereditary allergies or allergic contact dermatitis, involving dark circles around the orbits.

5. Miscellaneous. For example, dark eye circles can occur due to excessive use of cosmetics, smoking, old age, irregular menstruation, the third trimester, excessive sexual intercourse, and certain liver and kidney diseases.

Therefore, after the formation of dark circles, you should see a doctor in time and under the guidance of a doctor**.
