In ancient literature of various asanas helpful in the control of breathing (pranayama) and relaxation and meditation (Shavasana).
In India, Yoga practiced to alleviate and improve the physical, mental, social and spiritual health. There is a need to show that yoga is not merely an exercise system but it has many more health benefits. Complementary Alternative Medicine (CAM)1suggested that yoga is a holistic approach followed by the western world from 3000 years.[1]
Stress management and its negative emotions were reduced by yoga. More studies stated that yoga has improved health substantially many clinical trials have been designed to assess its therapeutic importance and health benefits.[2]
Our analysis mainly represents the effectiveness of yoga in reducing the anxiety and to improve the quality of life among the volunteers and also evaluate the association of selected demographic variables with the level of anxiety.

Sampling criteria
Post assessment
Subjects in the study and control group were evaluated at 4 weeks on anxiety and quality of life based on the above-mentioned scales.
Data analysis
Data were analyzed using Paired' test was used to compare the Pre and Post-test scores within the same group.
Results and observations
There was no significant difference in age distribution, sex education, and occupation. ([Table 2]) of volunteers among the control and experimental group. ([Table 2])
It could be observed that the anxiety levels of volunteers in the control and experimental group didn't differ significantly (p=0.72, for anxiety). ([Table 3])
There was no difference between the control and experimental group on the overall quality of life among the volunteers attending the yoga center at the pre-test level significantly. ([Table 4] ).
There was no relation between various demographic parameters associated with anxiety. ([Table 5]).
Shows that the levels of anxietyand all the four domains of quality of life did not differ significantly between pre and post-assessments in the control group.
From the above table 6 that anxiety level of the subjects was significantly lower at the post-assessment, 11.40 vs. 6.53 in the study group and also improves the quality of life.
The study group had significantly lower anxiety and a higher quality of life compared to the control group. ([Table 8]).
Discussion
In the present study, there was no significant difference in mean score in both the control and study group. (p=0.722). These results revealed that an abnormal level of anxiety in both the groups as per the Hamilton Anxiety Rating scales. Our findings were similar to earlier reports stated by Woolery et al (2004).[3]
According to the quality of life among the subjects in both groups were evaluated several selected domains such a. Physical health, psychological health, social relationship, and environment. The study reveals that which differs significantly between the experimental and control groups.
In the present study concerning socio-demographic variables none of these variables significantly associated with anxiety. From these results, the levels of anxiety do not differ significantly between pre and post-assessments in the control group (p = 0.06). Present findings confirm that there was a significant reduction in anxiety and a significantly higher quality of life after the Yoga intervention.
Present study accordance with the previous studies Malathi et al (2000)[4] studied forty-eight healthy volunteers who participated in the practice of Yoga over for 4 months. Another study reported by Michelson et al (2005)[5] which are related to our findings.
The experimental group had significantly lower anxiety levels and significantly higher quality of life compared to the control group. Our findings were similar to previous studies were observed by Javnbakht et al (2009),[6] Khumar et al (1993)[7] and Janakiramaiah et al (1998).[8]
The quality of life such as physical health, psychological health, social health, and environmental health features improved by an integrated yoga program. Several studies experimentally proved with scientific observations on the quality of life enhanced by yoga.[9], [10], [11], [12], [13], [14], [15]
In ancient literature yoga results in the balance of body that help tolerance of various environmental changes.[16], [17]
There was a various limitation in the present study such as; relatively small sample size, short duration and it needs scientific validation.
Conclusion
We conclude that yoga practice may represent an effective improvement in patients with anxiety. Different yoga practices can be encouraged to be used as a non- pharmacological remedies to reduce anxiety and improve the quality of life.
