 Stress sucks. It can affect your body and mind.Previous researchers have shown that stress can even hinder our ability to remember. But these studies had typically focused one stress of time. What happens when we face multiple stresses? Researchers looked at pond snails 1 often used in memory research. The trained the snails to reduce how frequently they breath out of the water. They then tracked whether the snails remember their training after being stressed. The snails' memory was considered in attack if they reduce third tenth to breath when they removed from water. Two common stressors--low level of calcium 2 necessary for strong and overcrowding by other snails can happen in combination of wild. Individually, these stressors only block the formation of new long-term memory in the snails. But combined they caused the snails to forget their training. That is they prevented any new memories from been formed. The study is in the journal PlosOne. It's thought these snails and mammals have similar responses to stress. Of course, when stress out, we should remember to breath more not less.
