Can going from a highly intensive and stressful environment to one which is calm and relaxed impact long-term memory or, specifically, one's ability to easily recall information?
For example, I have spent the past year in a very intense and stressful academic environment where I would often go for days without sleep. During this time, I was able to quickly recall information and do very well. However, now that I am on "summer break" I am noticing that my memory is not as sharp. Specifically, I am having difficulty recalling names and specific pieces of information that I should know. This occurs on only on occasion and only happens with things that are more obscure or non-essential (i.e. couldn't come up with the name to a song I know all of the lyrics to. I knew the title immediately once I saw it).
This has happened to me once before while on break and shortly after returning to work I noticed that my memory had returned to normal. This only happens with names and it almost feels as though there is a mental block preventing me from remembering.
Is there an explanation as to why this is occurring?
As a note: I am still a teenager so age is hopefully not a factor.
