First and foremost, you should get enough sleep. There is a research showing that sleeping for 4 to 5 or less every day has negative effects on your health. A healthy diet that is rich in vitamins is very important. Your diet should contain more fresh fruits and vegetables. Besides, food like lobster, sardines, shrimp, raspberries and nuts can also work to alleviate the dark circles. Putting cucumber slices over your eyes before bedtime for 5 to 10 minutes is also effective. After you have drunk a cup of green tea, do not throw the tea bag away. Put the tea bags in the refrigerator to cool them down, and then apply them to your eyes for a few minutes. When you are out, it is also necessary for you to wear sunglasses to protect your eyes from UV that worsens the condition.
