Today, I will talk to Xiao Nan about eye edema ~
Why does the eye edema after crying? Under normal circumstances, tears produced during mood swings are "richer" than ordinary tears. It contains more prolactin, adrenocorticotropic hormone and other substances, and the content of protein is also 20% more; The potassium concentration and manganese content of emotional tears are higher than those of ordinary tears. This leads to higher osmotic pressure and colloid osmotic pressure of the crystal than ordinary tears.
Therefore, when a large number of "emotional tears" gather around the eyelid, the osmotic pressure of eyelid tissue increases, so the liquid in the blood vessels seeps out to form tissue fluid, which makes the subcutaneous tissue swell and form "edema" in appearance, which is called "water retention" academically.
This edema is temporary. After stopping crying, the eyes will swell with the recovery of osmotic pressure balance around the eyes. In addition, people rub their eyes more or less when they cry. Rubbing eyes may cause damage to eyelid tissue and conjunctiva, leading to exudate of tissue fluid. In other words, friction is also one of the causes of tissue edema.
Other causes of eye edema Some edema are pathological, such as eyelid furuncle, blepharitis, eyelid dermatitis, dacryocystitis, orbital cellulitis, severe acute conjunctivitis, sinusitis and other diseases, which will all cause symptoms of eye edema and should be hospitalized in time.
Some edema is non-pathological, such as eye allergy, eyelid skin edema caused by mosquito bites. At this time, it is necessary to prescribe the right medicine and choose anti-allergic drugs to relieve discomfort.
Some edema has a lot to do with diet and work habits. "Crying swelling" belongs to this kind of situation, and the common situations are:
Menstrual edema
Some girls will have eye edema before menstruation, which may be related to the secretion of estrogen. After menstruation, it will subside by itself without special treatment.
Drink too much water or eat too salty before going to bed.
Some people like to drink water before going to bed, or eat too salty dinner, which will lead to too many sodium ions in the body and cannot be excreted. At this time, the body will absorb more water to help maintain balance, so edema will occur.
stay up late
Staying up late can also cause eye problems such as bags under the eyes and dark circles, so it is necessary to reduce staying up late and maintain adequate high-quality sleep.
Incorrect sleeping position
Some people like to sleep on their stomachs, which will cause the skin and blood vessels around their eyes to be compressed, which will easily lead to poor circulation and edema.
How to eliminate edema and quickly eliminate eyelid edema ① Ice the edema area. You can use cooled black tea bags, cucumber slices and so on. Or wash your face with cold water.
② Massage. Pat or massage your eyelids and eyes gently with a cold iron spoon, and don't rub your eyes.
Long-term prevention of eye edema ① Eat less salt. The Nutrition Society of China suggests that healthy adults should eat 6 grams a day. Eating too much salt can also cause chronic diseases such as hypertension and obesity.
② Keep enough sleep. Ensure more than 7 hours of sleep every day and avoid staying up late. Sleep correctly, don't sleep with your head covered or your mouth wide open, and don't sleep on your stomach.
