If your eyes are swollen from crying, you can reduce the edema as soon as possible by doing cold compresses on the eyes. On the one hand, the eyes are swollen due to excessive tear secretion when crying, liquid accumulation in the eyelids; on the other hand, crying emotional, can also cause some blood vessel inflammatory reaction, caused by intravascular fluid exudation, resulting in eyelids and other loose soft tissue parts of the edema. The first thing you can do is to apply cold compresses to the eyes. Cold compresses can lower the temperature of the local tissues, contract the blood vessels in the subcutaneous tissues, and reduce the leakage of intravascular fluids into the tissue interstitial space, thus promoting the subsidence of edema. Stop crying, cold compresses for a period of time, if the symptoms of swelling are not relieved, or even other eye discomfort such as eye redness, eye pain, etc., it is recommended to consult a doctor for examination and treatment.
