STRESS



Besides increasing your risk of heart disease, depression, and obesity, stress decreases your cognitive performance.

The tricky thing about stress (and the anxiety that comes with it) is that it’s an absolutely necessary emotion. Our brains are wired such that it’s difficult to take action until we feel at least some level of this emotional state. In fact, performance peaks under the heightened activation that comes with moderate levels of stress. As long as the stress isn’t prolonged, it’s harmless.

Research from the University of California, Berkeley, reveals an upside to experiencing moderate levels of stress. But it also reinforces how important it is to keep stress under control. The study found that the onset of stress entices the brain into growing new cells responsible for improved memory. However, this effect is only seen when stress is intermittent. As soon as the stress continues beyond a few moments into a prolonged state, it suppresses the brain’s ability to develop new cells.
