2..What is the finding of the study yoga for bronchial asthma (A control study).

3.What does these findings have to do with yoga?

Answer 1

1) According to research, the present mini-review was aimed at exploring the frontal EEG asymmetry of mood. With respect to emotion, interpreted as a discrete affective process, mood is more controllable, more nebulous, and more related to mind/cognition; in addition, causes are less well-defined than those eliciting emotion. Therefore, firstly, the rational for the distinction between emotion and mood was provided. Then, the main frontal EEG asymmetry models were presented, such as the motivational approach/withdrawal, valence/arousal, capability, and inhibition asymmetric models. Afterward, the frontal EEG asymmetry of mood was investigated following three research lines, that is considering studies involving different mood induction procedures, dispositional mood (positive and negative affect), and mood alterations in both healthy and clinical populations. In general, results were found to be contradictory, no model is unequivocally supported regardless the research line considered. Different methodological issues were raised, such as: the composition of samples used across studies, in particular, gender and age were found to be critical variables that should be better addressed in future studies; the importance of third variables that might mediate the relationship between frontal EEG asymmetries and mood, for example bodily states and hormonal responses; the role of cognition, namely the interplay between mood and executive functions. In light of these issues, future research directions were proposed. Amongst others, the need to explore the neural connectivity that underpins EEG asymmetries, and the need to include both positive and negative mood conditions in the experimental designs have been highlighted.
2) Yoga, or its ancestor, first appeared some where around 5,000 years ago. Since then, it has gradually evolved in to the modern form. The word “Yoga” means union, joining or to link together as one whole according to Sansacrit language. Hath yoga is a physical method which uses the breath to link the various parts of the body and the mind and to allow them to behave as one functional unit which helps in the control of Asthma.
Yoga exercise among asthmatic patients resulted in a decreased number of day and night attacks and use of drugs. It also shows significant improvement in the peak expiratory flow rate. Further large scale study is recommended.
3)An analysis of yoga and heart health studies found that yoga reduced risk factors for heart disease, such as body mass index (BMI), cholesterol, and blood pressure. Yoga may also decrease changes in the blood vessels that contribute to heart disease.
