After everything I have learned throughout Psychology, the one concept that will stick with me most is the concept of sleep. The idea of sleep may seem simple and self-explanitory but people (including myself) underestimate the importance of sleep. Sleeping is one of the most important aspects of life, After a good night's sleep you feel better, your thoughts are clearer, and your emotions are less fragile. Without adequate sleep, judgment, mood, and ability to learn and retain information are weakened. I have learned this already in college and have seen the effects of sleep reflect in my grades. I wonder if scientists will discover the exact scientific reasoning behind why sleep is so important in our lives. I will always remember how important sleep is and make sure to get the suggested amount of sleep so I can receive the healthy amount of REM sleep I need in order to be healthy. Another thing I wonder is if all people have the same sleeping cycles at night. Overall, it is important for everyone to get the suggested amount of sleep each night and be consistent.
