There are several causes for puffy eyes: fatigue, stress, lack of sleep, alcohol consumption, high-salt diet, allergies, environmental toxins, hormonal changes—you name it. Everyone knows about that good old natural cure: cucumber slices. But tea bags are also a great help. Tannins and antioxidants in tea help to diminish swelling and fluid retention in the delicate tissues surrounding your eyes. Caffeine contracts the blood vessels and reduces the puffiness. Just apply brewed (but cooled) tea bags on your eyes for 10 minutes and relax. For an extra treat, chill the tea bags before applying to your eyes.
