A quantitative review of seven online randomized controlled trials found that meditation-based interventions significantly reduce overall distress (depression, anxiety, stress) by 20.5% to 68.8% and moderately improve insomnia by 5.2% to 38.5%. For long COVID, effectiveness varied widely across 13 symptoms, from 0.0% to 71.2%. The review provides compelling evidence that meditation-based interventions can alleviate these five prevalent disorders arising from the pandemic.
A review of 13 studies involving 574 generally healthy adults examined how Mindfulness-Based Stress Reduction (MBSR) affects mindfulness and stress. Mindfulness improvements ranged from 3.77% to 26.80%, and stress reductions ranged from 8.41% to 49.05%. A strong positive correlation emerged between increased mindfulness and decreased perceived stress, suggesting MBSR can enhance mental well-being and may be useful in broader mental health initiatives.
A meta-analysis of eight studies found that Mindfulness-Based Stress Reduction (MBSR) interventions for cancer patients and survivors increased mindfulness by an average of 7.93% and reduced stress symptoms by an average of 22.58%. A regression analysis showed a strong negative correlation between mindfulness and stress, suggesting that increases in mindfulness are associated with decreases in stress. The authors conclude that MBSR is effective for enhancing mindfulness and alleviating stress in this population and recommend its use as a complementary therapy in cancer care.
Mantra meditation, a simple practice suitable for both beginners and experienced meditators, provides beneficial effects on stress, anxiety, hypertension, and immunity. This review of recent studies finds evidence that mantra meditation yields various degrees of mental and physical health benefits, though the authors recommend larger, higher-quality studies to draw firm conclusions. The review covers quantitative evidence from trial outcomes without considering spiritual motivations, aiming to confirm and add scientific support for the practice's health effects.
