Question

Discuss 2 physiological changes experienced by the human body when in a mindful resting state and how they might affect the cardiovascular system.

Answer 1

Answer : physiological changes due to mindful resting state :

People who practice meditation daily have unusual EEG patterns, lower respiratory levels, steady blood pressure, and enhanced immune responses. Controlled studies have shown that mindfulness meditation can help fight anxiety, depression, substance abuse, and addiction.

Physiological tests such as EEG give promise as objective measures to assess meditation ability due to their responsiveness to meditation. EEG variations are well established during variations in the meditation state and from long-term cross-sectional trait differences in meditation. Once spectral analysis parameters are found that are sensitive to meditation on total brain activity, spectral coefficients can be used to construct a classifier to distinguish between meditation and control conditions.

Respiration may also be a reliable physiological marker for mediation. Some studies have shown that meditation slows down the breathing rate without direct instructions.Experienced meditators are reported to have slower breathing rates compared to rest controls and slower minute ventilation during meditation. Slow breathing may be a simple physiological marker within the subject to evaluate whether or not a person is meditating.

Meditation can have a positive effect on the measure of heart health known as heart rate variability (HRV). HRV reflects how quickly your heart makes small changes to the time interval between each heartbeat.A 2013 study found that low HRV is associated with an increased risk of heart attack or stroke of 32% to 45% in people without cardiovascular disease.
