1 of 3

Seasonal affective disorder (SAD), sometimes called the “winter blues”, is a type of depression that many people suffer from. But it is much more serious than a simple case of the blues.

It is associated with the changing seasons. Often, the symptoms begin to worsen with the onset of fall and peak during the winter months, usually as a response to the shortened daylight hours. However, it can even occur during the seasonal shift from spring to summer.

SAD causes the serotonin and melatonin levels in your body to drop, which give rise to different symptoms. Typical symptoms of SAD are feelings of hopelessness, lack of concentration, social withdrawal, anxiousness, sadness, anxiety, lethargy, and fatigue.


SAD is a serious condition that requires professional treatment. Light therapy and exercise, as well as prescription medication, are all used to combat SAD.

In addition, certain foods can help you deal with this problem. These foods are great sources of the nutrients your body and brain need to stay alert, productive and content.

Salmon is rich in omega-3 fatty acids – particularly DHA and EPA – that help improve symptoms associated with depression. Fatty acids boost production of dopamine and serotonin, the feel-good chemicals in the brain. On top of that, these essential fatty acids have been linked to improved memory and healthy brain function.

A 2006 study from the University of Pittsburgh found that people with higher levels of omega-3 fatty acids were less likely to experience moderate or mild symptoms of depression .

A 2016 study published in the Journal of Nutrition & Intermediary Metabolism reports that a dietary long-chain omega-3 fatty acid deficiency may represent a modifiable risk factor for depression .

This cold-water fish also provides your body a good amount of vitamin D.

3. Bananas

Eating a few bananas a day can help keep you happy and alleviate SAD symptoms.

Bananas contain tryptophan, a type of protein that the body converts into serotonin, which helps you relax, improves your mood and generally makes you feel happier. Tryptophan also works with two other hormones, noradrenaline, and dopamine, to lift your mood and promote relaxation.

According to a 2015 study published in the Archives of Psychiatric Nursing, consuming more dietary tryptophan resulted in less depressive symptoms and decreased anxiety .

Bananas are also loaded with vitamin B6, potassium and magnesium, which are all powerful nutrients that have stress-reducing properties and help fight symptoms associated with depression.
