Robert Bonakdar, MD, director of pain management at Scripps Center for Integrative Medicine, explains why meditation may alleviate anxiety and depression. Dr. Bonakdar says meditation promotes a neurochemical shifting and lowers stress hormones. Consequently, the brain generates natural anti-anxiety and happiness-enhancing chemicals like endorphins and (high levels of) serotonin. In addition, meditation helps people to cope from stressful situations and blocks depression-causing inflammatory neurochemicals from pouring out.
