Effects of Mindfulness-based Intervention on Epigenetic Mechanisms, Cognition Function, Stress Response, and Well-being

Mindfulness-based intervention encompasses different practices which intend to exercise awareness by using mindfulness meditation training moment by moment. Thus, practices such as mindful breathing, compassionate communication, loving-kindness, self-compassion, mindful listening, dealing with difficulties, the 3 step meditation, walking meditation, body scan with progressive relaxation, thoughts, emotions, gratitude, and sounds and breathing will be teaching to participants. Mindfulness training will be conduct by two instructors with more than 30 years' experience in meditation practices (Zen and Tibetan Buddhist approach to mind-training) and extensive mindfulness teaching and practices (\> 5 years each) experiences.

Participants will receive lectures that provide cognitive and sensorial stimulus which does not specifically involve awareness training (meditation). Lesson topics include science.
