Continued from Causes of Insomnia.

Since some causes of insomnia and other sleep disorders are often linked to food allergies, pay special attention to your diet. Avoid mucus-producing dairy and bananas to see if you notice a difference.

Add more essential fatty acids from salmon, sardines, walnuts, and flaxseed, which can help decrease allergic reactions as well as inflammatory conditions like arthritis.

In the evening, dine lightly on poultry, tuna, whole grains, and unsweetened yogurt with live cultures — all rich in tryptophan, which stimulates sleep-conducive neurotransmitters.

B vitamins are essential for a good night’s sleep, so sprinkle a little brewer’s yeast in your favorite shake or on your dinner salad. Cut down on caffeine, found in chocolate, colas and other soft drinks, medications, and black and green teas as well as coffee.
