Studies

There is so much information and misinformation about mental health online, I recommend using Google Scholar as your search engine to look up the latest scientific articles.

Here are a few studies I have found particularly interesting: 

The effects of meditation on perceived stress and related indices of psychological status and sympathetic activation in persons with Alzheimer's disease and their caregivers: a pilot study.

A meta-analytic review of the effects of mindfulness meditation on telomerase activity

Interventions for children and adolescents with posttraumatic stress disorder: A meta-analysis of comparative outcome studies

Exercise as a treatment for depression: A meta-analysis.

Bright light therapy for nonseasonal depression: Meta-analysis of clinical trials.
