  • Yoga is arguably the most comprehensive approach to fighting stress.
  • Yoga improves the quality of life.
  • It also appears to diminish the side effects of surgery, radiation, chemotherapy, and other treatments, and may increase the odds of survival.
  • Many yoga practices, including quiet asana, slow breathing, meditation, and guided imagery, increase activation of the parasympathetic nervous system and lead to mental relaxation.
    • The parasympathetic nervous system slows the heart and lowers blood pressure, allowing recovery after a stressful event
