Multiple reasons such as a bad sleep, too many fluids intake before bedtime, sun overexposure, frequent scratch by hands and allergy can cause swelling eyes.
As a result, the tiny vessels around your eyes blocked. Further, a nasal congestion has the same impact. What is more, cooling agents, potato or cucumber slices, eggs whites and mint leaves can open the vessels and unblock the blood circulation. For example, after putting in the freezer for more than half hour, you can wrap an ice cube by wash cloth or cool tea bags, and then place on your eyes or forehead. As for the mint leaves, you can blend the water and mint thoroughly so that you can get rid of swollen eyes.
