Stone Age Self-Help

Here's an article(pdf) about a "Stone Age" approach to depression.  The author believes there are six key to treating depression in the modern world:

• Sufficient sleep
• Omega-3 fats
• Aerobic exercise
• Sunlight exposure
• Socialization
• Less rumination

Some newer studies show this combination may be as effective as traditional treatment (i.e. drugs).  A recent analysis(pdf) of this technique tried to find out which part was the most potent, with less rumination coming out as the only significant variable.  But at the very least, this type of common-sense program is a solid basis for treating mental health issues with evoutionary insights.
