Stress affects all parts of our physical, emotional and endocrine systems. The negative effects of stress, however, can be combated through the practice of yoga. In addition to improving emotional balance, yoga helps reduce the reaction of the yogi (yoga practitioner) to unpleasant events. The practice of this art creates in the long-term a sense of calm and positive attitude which in turn have positive impacts on both physical and mental health. Meditation through the practice of yoga allows the mind to be more synchronized with the body. With this in mind, it should be noted that the ancient yogis practiced meditation independently of yoga, as their ultimate goal was self-realization and enlightenment. Yoga postures (called asanas) had the effect of accelerating their metabolism and reducing their stress. Yoga also increases the lubrication of joints, ligaments and tendons, as well as simply exercising them. In addition, yoga is one of the few exercises that massage the internal organs which otherwise rarely receive external stimulation during a person’s life. Stimulation and massage of the organs also contribute to a healthy immune system and brings the yogi closer to their body. Performed at any age, yoga tones otherwise weak and flabby muscles; with repetition, it removes grease and hardens them. Meditation decreases oxygen consumption in the body by decreasing the rate of breathing.
