A bit of stress can actually help you remember much more efficiently than when you are relaxed. Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley states: “Some amounts of stress are good to push you just to the level of optimal alertness, behavioral and cognitive performance.”
When tested on rats, it was found that small stress caused their brains to produce new stem cells and overall improved the rats’ mental performance. The brain becomes aware and alert, which is the optimal levels to for brain activity. As it goes for human nature it has been discovered that stress has been beneficial for animals to remember certain events: “Stress hormones help an animal adapt – after all, remembering the place where something stressful happened is beneficial to deal with future situations in the same place,” said Bruce McEwen, head of the Harold and Margaret Milliken Hatch Laboratory of Neuroendocrinology at The Rockefeller University.
Yet if you are severely stressed if can actually plummet the neurogenesis of the brain. Exposure to acute, intense stress can sometimes be harmful, leading, for example, to post-traumatic stress disorder. Further research could help to identify the factors that determine whether a response to stress is good or bad.
In short, even though stress is normal, we don’t quite take into consideration the affects. Moreover, how much it controls and hinders the important parts of our neurological system.
