Brain Scans Reveal Changes After a 45-Day Yoga Programme, Study Reports

Mental wellbeing is influenced by several factors, including stress, sleep, physical activity and social environment. Researchers continue to investigate whether structured mind-body practices can support emotional health and cognitive functioning.

The reported trial involved 139 healthy adults who participated in a 45-day standardised yoga programme or a comparison condition. Researchers assessed mood, sleep quality and selected memory measures. Brain imaging was also conducted in a subgroup of 43 participants.

The yoga group showed improvements in mood and self-reported sleep quality, along with changes in selected short-term memory measures. Brain scans identified differences in functional connectivity across networks involved in movement, attention, language and cognitive processing.

Functional connectivity refers to patterns of coordinated activity between different brain regions. Changes in these patterns may help researchers understand how behavioural interventions influence brain function.

However, the long-term significance of the observed brain changes remains uncertain. The study does not establish yoga as a treatment for psychiatric disorders, and its results in healthy adults should not be generalised to people with severe mental-health conditions without further research.
