All of us know that yoga and meditation possess countless benefits like increased strength to flexibility to heart health.

However, we still have much to learn about how exactly these practices affect mind-body health.

A new research article investigates the effects of yoga and meditation on brain derived neurotrophic factor (BDNF), the activity on the hypothalamic pituitary adrenal (HPA) effects and inflammatory markers.

By studying the participants of an intensive three-month yoga and meditation retreat, the researchers found that the practices positively impacted BDNF signaling, the cortisol awakening response (CAR) and immunological markers, and in addition improved subjective wellbeing.

In this study, the retreat participants were assessed before and after participating in a 3-month yoga and meditation retreat that involved daily meditation and Isha yoga, accompanied by a vegetarian diet.

The yogic practices consisted of physical postures, controlled breathing practices, and seated meditations during which the participants focused on mantra repetition, breath, emptying the mind and bodily sensation.

The researchers measured psychometric measures, brain derived neurotrophic factor (BDNF), circadian salivary cortisol levels, as well as pro- and anti-inflammatory cytokines.

They also collected data on psychometric variables including mindfulness, absorption, depression and anxiety, and investigated the relationship between psychological improvements and biological changes.

The data showed that participation in the retreat was associated with decreases in both self-reported anxiety and depression as well as increases in mindfulness.

The research team observed increases in the plasma levels of BDNF, a neuromodulator that plays an important role in learning, memory and the regulation of complex processes such as inflammation, immunity, mood regulation, stress response and metabolism.

They also observed increases in the magnitude of the cortisol awakening response (CAR) which is part of the hypothalamic pituitary adrenal axis (HPA), suggesting improved stress resilience.

Moreover, there was a decrease in inflammatory processes caused by an increase of the anti-inflammatory cytokine Interleukin-10 and a reduction of the pro-inflammatory cytokine Interleukin-12 after the retreat.
