If you get up every day with edema in the eyes, if you have the habit of drinking water at night before going to bed, you can ensure that you enter a light diet, control the daily intake of sodium chloride not more than 6 grams, and reduce the amount of water drunk before going to bed, elevate the pillow appropriately, apply heat to the eyes every night before going to bed, and see if the symptoms of swelling in the eyes are reduced or disappear when you get up early in the morning. Mosquito bites are a common cause of eye edema in summer and autumn, which will improve naturally after rest. The basic condition of the kidney can be ruled out, and the cause of the disease can be determined and then treated professionally to restore health in a timely manner. Seasonal allergies or contact dermatitis can also cause ocular edema and require anti-allergy treatment. If the cause of ocular edema is not detected, it may be angioneurotic edema and can be ignored.
