Stressful Sleep Loss may Impair Memory

Being that we are all college students and we do things which are not the greatest for our bodies. It should be known that the type and amount of sleep we get can affect our memory. According to this article, stressful sleep induces a stress hormone which then causes the hippocampus to not produce adequate amounts of brain cells. This can cause memory problems because the hippocampus is the learning center of the brain.
These may or may not apply to humans because the studies were done on rats. The researchers didnt allow the rats to sleep and had them in a stressful situation. The results showed high levels of a stress hormone with decreased brain cells in the hippocampus.
Being college students we have sleep loss but there may be a difference depending on the type of sleep loss. If it is due to stress, such as someone keeping us awake, then it could affect us much more if it is due to enjoyment however there can be different effects of which may not effect our memory.
