 Stress sucks. It can affect your body and mind. Previous research has shown that the stress can even hinder our ability to remember; but these studies have typically focused on one stress at a time. What happens if we face multiple stresses? Researchers looked at pond snails1 often used in the memory research. They trained the snails to reduce how frequently they breathe out of water. They tracked whether the snails remembered their training after being stressed. The snail’s memory was considered intact if they reduced their attempts to breathe removed from water. Two common stressors: low levels of calcium2 necessary for strong shells; and overcrowding by other snails can happen in combination in the wild. Individually, these stressors only blocked the formation of new long-term memories in the snails; but combined, they caused the snails to forget their training. That is, they prevented any new memories from being formed. The studies is in the journal … one. It’s thought that these snails and mammals have similar response to stress; of course, when stressed out, we should remember to breathe more, not less.

PS: I tried very hard and listen to it many times. It’s not easy to comprehend sometimes. Please correct errors in this short paragraph. Thanks.
