Stress is necessary for life. You need stress for creativity, learning, and your very survival. Stress is only harmful when it becomes overwhelming and interrupts the healthy state of equilibrium that your nervous system needs to remain in balance. Unfortunately, overwhelming stress has become an increasingly common characteristic of contemporary life. When stress throw your nervous system out of balance, relaxation techniques can bring it back into a balanced state by producing the relaxation response, a state of deep calmness that is the polar opposite of the stress response.

When stress overwhelms your nervous system your body is flooded with chemicals that prepare you for "fight or flight". While the stress response can be lifesaving in emergency situations where you need to act quickly, it wears your body down when constantly activated by the stresses of everyday life. The relaxation response puts the brakes on this heightened state of readiness and brings your body and mind back into a state of equilibrium.
