When the brain is stressed, cascades of chemicals are sent to the adrenals to prepare for an event, including cortisol (Jensen, 2008). Cortisol is a hormone that is a temporary source of energy, and for half an hour or even a few hours,
it can be helpful (Jensen, 2008). However, over the course of days, weeks, or months, chronically high levels of cortisol wreak havoc on the brain (Jensen, 2008).
By incorporating some brain-based learning techniques, we can hope to alleviate some of the stress caused by standardized testing, deadlines, and even some stresses at home. Brain-based learning provides a non-threatening environment conducive for learning. A brain needs just enough stress to spark an interest in solving the problem. However, we must be careful to maintain the balance. A distressed learner will not retain information as well as a non stressed learner.
