Almost every day we hear of new research which shows the harmful effects of undue stress on our mental and physical health. Yet stress is increasing in the workplace. Now a study published on the journal PLoS One shows that repeated stressors can have a have a serious effect on memory retention and learning. The research was done with species of ‘smart’ pond snails since these creatures react to environmental pressures in a similar way to mammals (including humans) but have far simpler brains. If the researchers are right then it would seem to follow that employees exposed to multiple work or family stressors will probably suffer severe long-term memory impairment (as well as cardiac problems, depression, PTSD, diabetes, cancer and a load of other problems). Not good news in most modern workplaces!
