Meditation is widely praised for boosting cognitive function and easing anxiety, but a comprehensive meta-analysis reveals it may pose risks for certain individuals.
In July 2020, research highlighted how meditation enhances brain volume in key areas like the hippocampus (for emotion regulation) and the temporoparietal junction (linked to empathy and compassion). Overall, this practice is associated with sharper cognition, better focus, and greater well-being, while also lowering stress and anxiety levels.
However, effects aren't universal. A meta-analysis, reported by New Scientist on August 14, 2020, and set for publication in Acta Psychiatrica Scandinavica, challenges the notion. Led by researchers at the University of Coventry in the UK, it reviewed 55 rigorous studies, primarily on mindfulness meditation.
The analysis found that 8% of participants (about 1 in 12) experienced negative side effects, including panic attacks, heightened anxiety or depression—sometimes for the first time.
Importantly, this doesn't undermine meditation's proven benefits for most. Instead, it calls for guided practice under qualified supervision. The researchers stress it's not "universally beneficial."
Katie Sparks, a registered psychologist with the British Psychological Society, notes that some individuals struggle with mind and thought control, potentially explaining counterproductive outcomes.
Echoing this, a 2019 University College London study of 1,232 respondents found about 25% reported distressing psychological experiences, such as fear or distorted emotions.
