—Mindfulness meditation has been taken as a
method to release the short and long terms of stress and anxiety.
A questionnaire was investigated to measure the effect of
mental change as well as the changing of brain signals while
doing the mindfulness meditation. Ten healthy-young
participants were recruited to investigate the effect of
mindfulness meditation compare with self-relaxation. Brain
activities from participants were recorded during practicing
mindfulness meditation using Electroencephalogram (EEG)
with 10-20 system of electrode placements. A questionnaire with
30 questions was applied to estimate meditation depth. The
differences between self-relaxation and mindfulness-meditation
were analyzed according to meditation depth and brain
activities recorded with EEG. Compared with self-relaxation,
mindfulness-meditation reduces hindrance and increases the
level of relax. Although subjects were subjectively unaware of
the calmness during mindfulness-meditation practice,
compared with self-relaxation, the recorded data suggested that
mindfulness meditation reduces the short term induced tension,
indicated by the significant increment of theta and alpha power
spectrum of brain activities along the time.
—Alpha rhythm, theta rhythm, meditation
depth, stress reduction.
