Meditation and Psychophysical Well-Being in Elderly

The goal of this experimental study is to assess whether a mindfulness-based meditation intervention can reduce loneliness and improve psychophysical well-being in older adults (aged 65 and above). The main questions it aims to answer are: * Does the intervention reduce the perception of loneliness in older adults? (primary outcome) * Does it improve various aspects of psychological well-being, including social isolation, depression, life satisfaction, mindfulness, emotional regulation, self-acceptance, and sleep quality? (secondary outcomes) Researchers will compare the intervention group with a passive control group (waiting-list control) to determine whether the mindfulness-based intervention leads to significant improvements in the measured outcomes. Participants will: Complete baseline assessments, including neuropsychological tests and validated questionnaires, before the intervention. Undergo a 12-session mindfulness-based intervention over 6 weeks, consisting of guided breathing, focused attention, physical relaxation, and emotional awareness exercises. Complete post-intervention assessments to measure changes in their psychological and physiological well-being.
