Anxiety and depression are common in the modern world, and there is growing demand for alternative therapies such as meditation. Meditation can decrease perceived stress and increase general well\u2010being, although the physiological mechanism is not well\u2010characterized. Endocannabinoids (eCBs), lipid mediators associated with enhanced mood and reduced anxiety\/depression, have not been previously studied as biomarkers of meditation effects. Our aim was to assess biomarkers (eCBs and brain\u2010derived neurotrophic factor [BDNF]) and psychological parameters after a meditation retreat.\n                    <jats:italic>Methods<\/jats:italic>\n                    . This was an observational pilot study of adults before and after the 4\u2010day Isha Yoga Bhava Spandana Program retreat. Participants completed online surveys (before and after retreat, and 1 month later) to assess anxiety, depression, focus, well\u2010being, and happiness through validated psychological scales. Voluntary blood sampling for biomarker studies was done before and within a day after the retreat. The biomarkers anandamide, 2\u2010arachidonoylglycerol (2\u2010AG), 1\u2010arachidonoylglycerol (1\u2010AG), docosatetraenoylethanolamide (DEA), oleoylethanolamide (OLA), and BDNF were evaluated. Primary outcomes were changes in psychological scales, as well as changes in eCBs and BDNF.\n                    <jats:italic>Results<\/jats:italic>\n                    . Depression and anxiety scores decreased while focus, happiness, and positive well\u2010being scores increased immediately after retreat from their baseline values (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.001). All improvements were sustained 1 month after BSP. All major eCBs including anandamide, 2\u2010AG, 1\u2010AG, DEA, and BDNF increased after meditation by &gt; 70% (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.001). Increases of \u226520% in anandamide, 2\u2010AG, 1\u2010AG, and total AG levels after meditation from the baseline had weak correlations with changes in happiness and well\u2010being.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    . A short meditation experience improved focus, happiness, and positive well\u2010being and reduced depression and anxiety in participants for at least 1 month. Participants had increased blood eCBs and BDNF, suggesting a role for these biomarkers in the underlying mechanism of meditation. Meditation is a simple, organic, and effective way to improve well\u2010being and reduce depression and anxiety.\n
