If the dark circles under your eyes evoke images of boxing matches, it may be time to take things a bit slower and get more sleep. Note, however, that it could be more serious. An underactive thyroid, or a sensitivity to certain foods, could be to blame.
Take action:
If you are sleeping well, but still have circles under your eyes, consider eliminating possible food triggers from your diet. Start with wheat and then with cow's milk – these are common culprits. Also cut down on your salt and alcohol intake and drink at least eight glasses of water per day. If the problem persists, pay a visit to your doctor.
