New research has indicated that students who sacrifice sleep in order to cram for exams may be doing more harm than good. The study, which explores the link between sleep and memory, was recently published by scientists at Harvard Medical School.
According to their findings, people who deprive themselves of sleep so that they can study until the last minute are unlikely to remember anything that would improve their performance, while suffering the crippling effects of fatigue. The research indicates that the brain requires good-quality sleep after practicing a task to effectively learn and improve at it. Those who substitute study for sleep, particularly those who miss deep or "slow-wave" sleep will get little benefit from their extra effort.
The results, which have been published in the scientific journal Nature Neuroscience, support the growing body of evidence suggesting that sleep is crucial to the learning process. Professor Stickgold, who led the study, suggests that a good night's sleep immediately after learning is essential for embedding new skills in the memory. He explains that the first night's sleep is crucial in the process of memory consolidation, adding that memories may not be retained unless they are "nailed down" by certain processes. Based on the findings, it seems that sleep is one such process that plays a crucial role in solidifying new information in the memory.
