Here are some non-medical strategies for treating depression and anxiety:
Eat fresh, unprocessed nutritious food.
People who eat a diet high in fresh vegetables, fruit, fish, and whole grains are significantly less likely to be depressed or anxious than those who eat highly processed, sugary and fried foods and refined grain and drink beer and other alcohol.
Take supplements such as omega-3 fish oil. You need enough to get around 1000mg of EPA (eicosapentaenoicacid) a day.
A combination of zinc, vitamin B6 and magnesium is important for mood.
Get some sunshine – vitamin D – every day for a mood lift.
Get your heart rate up at least three to five times a week by doing uphill walking, dancing or fast yoga.
Accomplish something every day – something you’ve been putting off, like paying a bill.
Give yourself a treat every day – watch a movie, have a bubble bath, go for a swim or a walk.
Create a gratitude diary.
