While many people assume that our sleep is only beneficial for our energy levels, our quality of rest can actually indicate a great deal about our brain health and creativity. Sleep helps us improve our immunity and physical health, but it is also absolutely essential for our brain health and for our creativity, whether it be in problem-solving, writing, or other pursuits. If you’ve wondered why, then keep reading. In this article, we’ll explain precisely how sleep, brain health, and creativity connect.
We’ll take a look at how our quality rest supports cognitive health, clears toxins within the brain, and allows for more adaptability within the brain. We’ll even explore the connection between sleep and creativity, as well as how your sleep quality can enhance or hinder your stress levels.
Quality Sleep Supports Cognitive Function and Memory
It is no secret that great rest helps with enhancing cognitive function, especially given some of the research in the field. If you have ever found yourself struggling to remember something after a poor night of rest, it’s not a coincidence. Sleep is closely tied to cognitive function, and sleep quality can be influenced by physical activity. Therefore, if you have a healthy lifestyle and you sleep well, you may enjoy better cognition and memory.
However, what you might not realize is that poor sleep can actually put you at higher risk for cognitive decline and even Alzheimer’s disease. This is an essential insight that only further shows how important quality sleep is to cognition and memory. If you want to experience better cognition and memory, focus on your sleep health, and you’ll find yourself mentally prepared for problem-solving, memory recall, and more.
Proper Rest Helps Clear Toxins from the Brain
One fact many people rarely learn about sleep is how important it is for clearing out the brain and keeping it healthy. Just as your sleep helps you with physical health and supports your immunity, adequate rest is meant to help you eliminate neurotoxins from within the brain. During waking states, you have the tendency to collect neurotoxic waste, but your brain specifically uses a pathway called the “glymphatic system” to help with pushing out these toxins so you feel better and enjoy proper cognitive performance (Source: Current Opinion in Physiology).
Think of sleep as an opportunity for your brain to do some cleanup. No matter what may be within the brain, sleep can help you eliminate anything that could hinder your performance. As we mentioned, the quality of your sleep can either lower or increase your risk of neurodegenerative disorders, so make sure you support your brain’s natural cleanup of toxins and get enough rest every night.
The Better Your Rest, the More Adaptable Your Brain Becomes
When you prioritize quality rest, you’re helping your brain become more adaptable. This is also referred to as neuroplasticity, or your brain’s ability to experience adaptations both structurally and functionally that respond to experience and help enhance memory, cognition, and even learning (Source: PubMed). While you might think that this can occur on its own, it’s very much dependent on your lifestyle.
If you are sedentary, do not eat healthy, and experience poor sleep, you might find that you have poorer mental health and less neuroplasticity. This is because—with poor sleep—your brain does not have the ability to remove neurotoxins, and it also suffers from less cerebral blood flow. Inadequate sleep can actually limit your neuroplasticity, so if you’d like to ensure your brain’s continued adaptability and the development of new neural connections for learning as you age, make sure you take steps to protect your sleep and prioritize rest.
Sleep Helps with Inspiration and Creativity
Those who are creatives will be pleased to find out that your sleep actually helps with inspiration and creativity. Many people might state that they are more creative when they are sleep-deprived, but our sleep actually remains essential in solving problems, reorganizing our memories, and engaging in innovative thinking. Some experts studying the first stage of non-REM sleep discovered that sleep enhanced problem-solving and allowed for creative cognition, such as spontaneous thinking and creative idea generation (Source: Science Advances).
It's fascinating to think that our sleep can determine how creative we are and how much we can think critically. But it makes perfect sense: that’s why we are encouraged to get a good night’s rest before a big project or presentation and why we might find ourselves with a sudden stroke of inspiration when we wake in the morning. However, you may be even more surprised to find out that our sleep can actually help us alleviate harmful stress that could hurt the brain.
The Better You Sleep, the Better Your Stress Levels
Sleep is essential not only because it encourages us to think more creatively but also because it can limit our stress levels and promote proper mental health. Many studies have shown that improving your sleep can actually lead to some impact on stress levels and even limit some mental health symptoms and challenges. Interestingly enough, stress and sleep quality have a bidirectional relationship, meaning that they can impact one another.
A study on college athletes showed that sleep problems and mental health concerns were associated with stress, causing poorer sleep and vice versa. This is essential information for all populations, not just athletes. This only further proves that the better you sleep, the less stressed you may feel, and ultimately, the better your brain health will be because of it.
Take Steps to Promote Your Brain Health and Creativity
Sleep can astonishingly impact brain health and creativity, leading to optimal mental health, creative ideas, and peak mental performance. Now that you have the latest insights from the experts, you can take steps to help promote your overall health. What changes will you make to promote better sleep?
