What You'll Learn
Sleep helps strengthen memories
Research has shown that memories of certain procedures, like playing a melody on a piano, can actually improve while you sleep. Memories seem to become more stable in the brain during the deep stages of sleep. After that, REM—the most active stage of sleep—seems to play a role in linking together related memories, sometimes in unexpected ways. That’s why a full night of sleep may help with problem-solving. REM sleep also helps you process emotional memories, which can reduce the intensity of emotions.
Dr. Matthew Walker, a sleep scientist at the University of California, Berkeley, says, "We’ve learned that sleep before learning helps prepare your brain for the initial formation of memories, and then, sleep after learning is essential to help save and cement that new information into the architecture of the brain, meaning that you’re less likely to forget it."
According to a 2023 study on the impact of sleep deprivation on cognitive performance, sleep is crucial to our cognition. The study found that if you’re not sleeping enough, you could face “an impairment in attentiveness, working memory, consolidation of memories, alertness, judgement, decision-making, and many other diminished cognitive performances.” However, if someone is getting enough sleep, they will “be at an advantage with higher reaction times and intellectual activity.”
For younger people, especially students, it is recommended to get a good night’s sleep before learning. Lack of sleep can cut learning ability by up to 40%. It is also important to get a full night of sleep within 24 hours after learning to strengthen new memories and build connections between different pieces of information.

Sleep improves cognition
Secondly, sleep aids in problem-solving and creative thinking. The REM stage of sleep, in particular, helps to link related memories together in unexpected ways, fostering creativity and insight. A well-rested brain is better able to make connections and generate new ideas.
Thirdly, sleep is crucial for maintaining attentiveness, alertness, and judgement. A good night's sleep helps to improve reaction times and intellectual activity, enabling better cognitive performance. Conversely, sleep deprivation can impair these cognitive functions, leading to diminished attentiveness, alertness, and judgement.
Finally, sleep plays a role in emotional regulation. REM sleep helps to process emotional memories, reducing the intensity of emotions and aiding in emotional recovery. This can lead to improved emotional resilience and overall mental well-being.
In summary, sleep is essential for cognitive functioning. It helps to strengthen memories, enhance problem-solving abilities, improve reaction times, and regulate emotions. Getting sufficient, high-quality sleep is crucial for maintaining optimal cognitive performance and mental health.

Sleep aids problem-solving
Research has shown that getting a full night of sleep within 24 hours of learning is crucial for strengthening new memories and enhancing cognitive performance. Lack of sleep can reduce learning ability by up to 40%, impacting attentiveness, working memory, alertness, judgement, and decision-making.
Sleeping on a problem can also help us make more rational and thoughtful choices by reducing the impact of first impressions and snap judgments. During sleep, the brain engages in unconscious thought processes, weighing the relative importance of different attributes more equally and without the biases that influence conscious thinking. This allows us to make decisions with a clearer mind and improved concentration.
Additionally, sleep plays a role in processing emotional memories and reducing the intensity of emotions. This can help to improve problem-solving abilities by allowing us to approach issues with a calmer and more balanced mindset.
While "sleeping on it" can be beneficial for complex decisions where expertise is involved, it may not always lead to easier decisions. Some studies have found that participants who slept on a decision felt worse about their choice, despite having a better recollection of the attributes involved.
Overall, getting a good night's sleep is crucial for cognitive function, memory consolidation, and problem-solving. It helps to improve our decision-making abilities by enhancing memory, reducing biases, and allowing us to approach problems with a refreshed and more rational mindset.

Sleep helps the brain make sense of events
Research has shown that getting a full night's sleep within 24 hours of learning something new is crucial to strengthening those new memories and building connections with other pieces of information. Sleep also plays a role in linking related memories, which can help with problem-solving. For example, learning to play a melody on the piano; a good night's sleep can help to improve our memory of the melody.
Sleep also helps us to process emotional memories, reducing the intensity of emotions. This is because sleep allows our brains to recharge, enabling us to view situations in a clearer light and make more rational decisions. A study by Duke University found that participants who "slept on it" were less likely to be influenced by first impressions and made more balanced decisions.
Additionally, sleep can help us to solve complex problems. When we sleep, our brains sift through massive details, trying to find the best answer. This unconscious thought process during sleep can lead to better decision-making as it allows us to process information in parallel and weigh the relative importance of different attributes.
Overall, sleep plays a crucial role in helping our brains make sense of events, strengthen memories, and make better decisions.

Sleep helps with rational decision-making
Sleep plays a crucial role in enhancing memory retention and strengthening new memories formed throughout the day. Research has shown that a good night's rest can improve memory consolidation and facilitate the linkage of new memories to existing ones. This process is vital for learning and retaining information, making sleep an essential component of the learning process.
The benefits of sleep extend beyond memory improvement; it also aids in rational decision-making. A study by researchers at Duke University examined the impact of "sleeping on it" on decision-making. Participants were asked to choose items from virtual boxes of unwanted goods to include in an imaginary garage sale. The items varied in value, and participants earned real money based on their choices. The study found that participants who made decisions after sleeping no longer favoured boxes that made a good first impression. Instead, they made more balanced decisions, evaluating items more fairly, demonstrating that sleeping on a decision helps individuals make more rational choices.
Another study published in the Journal of Behavioral Decision Making supports these findings. In this study, participants chose laptop cases from a set of options with pros and cons. Interestingly, those who slept on it felt worse about their decisions, despite remembering more about the attributes of the cases. This suggests that while sleep enhances memory, it may not always lead to easier decisions.
Sleep also aids in problem-solving and emotional processing. During REM sleep, the brain links related memories together, fostering creativity and new ideas. Additionally, REM sleep helps process emotional memories, reducing the intensity of emotions and aiding in emotional regulation.
In summary, sleep is essential for memory consolidation and facilitates rational decision-making. It helps individuals make more balanced choices, reducing the influence of first impressions. While sleeping on a decision may not always lead to easier choices, it improves memory retention and fosters problem-solving abilities, ultimately contributing to improved decision-making capabilities.
