The ability to manage stress is the holy grail of brain management. Every other attempt to develop and use your brain well can be thwarted if you do not gain some level of control over your stress response. Unmanaged, habitual stress reactions interrupt the learning process, contribute dramatically to brain aging, and are at the root of numerous chronic disease conditions.
First of all, though, you should know that stress is not all bad. It is this process that allows us to respond quickly and effectively in emergency situations. When managed appropriately, the stress response helps stimulate the brain, improving mood and encouraging creative problem solving. Researchers
have found that minor amounts of stress, such as that experienced during basic life and occupational challenges, actually improve immune function, while extreme or prolonged stress has the opposite effect.
