SOLO NMF: "Sucking My Toes With The Vacuum"

This episode of Quick Brain, hosted by Jim Quick, explores the importance of cognitive rest beyond sleep, focusing on the default mode network (DMN). The DMN activates when the brain isn’t engaged in attention-demanding tasks, such as during daydreaming or mental wandering, and contrary to popular belief, it’s a highly active state that consumes 20% of the body’s energy—just 5% less than conscious effort. This network supports creativity, memory consolidation, and self-awareness by linking ideas and retrieving past experiences. To harness its benefits, Quick suggests practical methods: short naps (5 minutes) for mental clarity or longer ones (90 minutes) for creative work, guided positive daydreaming through low-bandwidth activities like coloring, and free walking, which studies show boosts thinking flexibility and originality. Even showering can trigger DMN activity, leading to sudden insights. However, an overactive DMN can cause excessive rumination, anxiety, and worry. To counter this, Quick recommends meditation and mindfulness to quiet the network, and cultivating awe—such as watching a sunset or hiking—to shift perspective and reduce trivial worries. Ultimately, optimal brain training requires balancing focused attention with deliberate unfocused time, integrating DMN-friendly practices into daily life to enhance both cognitive performance and well-being.

Welcome to Quick Brain, Bite Size Brain Hacks for busy people who want to learn faster and achieve more. I'm your coach, Jim Quick. Free your mind. Let's imagine if we could access 100% of our brain's capacity. I wasn't high, wasn't wired. Just clean. I knew what I needed to do and how to do it. I know Kung Fu. Show me. How to rest your brain. The importance of a good night's sleep is one of the most frequently mentioned health facts. Ask anyone. And they'll probably tell you that the eight hours of sleep is the optimal amount. We should all be striving for every night. It's not exactly false. And this is widely recommended by health practitioners everywhere. But the eight hours, seven to nine hours of sleep is not the only type of rest to your brain needs to keep functioning at its best. Welcome back, Quick Brain. I am your host and your brain coach, Jim Quick. Do you ever find yourself zoning out during the day? Well, it's not actually a bad thing. This mental wandering is a state of restful introspection or more commonly known as the default mode network. In today's episode, we'll dive into the importance of this state, how you can actively train it, and the advantages of giving your brain this type of restorative downtime. When thinking about ways to rest your mind and your body, our attention immediately draws to things like sleep, meditation, breath work, stretching, or taking a warm hot bath. But there is one other type of cognitive rest that we often practice unconsciously. And therefore, it doesn't immediately occur to us that we are doing it or should be actively applying it when needed. This rest state occurs when our brain engages in the default mode network. And you are not actively engaged in a task that requires a lot of attention. This is just a more complex way of saying that your brain's energy is no longer being used for conscious tasks. Basically, your mind is now allowed to wander or zone out. And this is a good thing. You might think that your brain has completely switched off and is not working during this state. However, the opposite is true. When you are sleeping or engaging in the default mode network, your brain is hard at work by consuming 20% of your body's energy while being in this unconscious state. In fact, putting in conscious effort requires just 5% more energy. Now, this network is especially active when you engage in introspective activities such as daydreaming, contemplating the past or the future or thinking about the perspective of another person. When you turn your focus brain off, it will retrieve memories and link ideas so that you can become more creative. And it will also help you feel more self-connected. For example, one of the benefits of free-flowing daydreaming is that it can often lead to higher states of creativity. So how do we actively train ourselves to use this network and achieve this type of rest? Well, this is how you train your default mode network. One of the ways is napping. If you are experiencing a mid-afternoon slump and all you want to do is fall into a deep sleep and you just need your mind to be clear, a 5-minute nap might be all you need for sharper thinking. But for example, if you have a major creative project ahead of you, you will need at least 90 minutes of napping time. This gives your brain enough time to shuttle around ideas to make the associations that it needs to make. Another way is daydreaming. To harness the power of daydreaming, you have to guide your thoughts. Luckily, you have more control over your daydreams than your nighttime dreams. This is where positive, constructive daydreaming comes in. It is essentially the practice of lulling yourself into a guided fantasy. To do this, you'll want to engage and are you going to let AI replace you or are you going to become irreplaceable?

A low bandwidth activity, for example, coloring or knitting a simple pattern could be an option. As you engage in that activity, allow yourself to entertain a wishful image. Maybe you're relaxing on a beach somewhere with a sun on your back, swimming in the sea, or a forest bathing, whatever image you choose, the key is not to become too invested. Simply use the image as a starting point for allowing your mind to wander. As you stop controlling the image, your thoughts will likely turn more inward and your brain will engage the default mode network. As already mentioned, when this brain mode gets activated, it will help you achieve a special kind of productive cognitive rest that you need. In the brain, thinking supports movement and movement supports your thinking. As your body moves, your brain grooves. In fact, exercise improves how your default mode network functions, and even a single session can make a difference. This has been found that aerobic exercise can help prevent atrophy of key regions within the network and also help with the connectivity between different brain regions. We know that walking helps you untangle our thoughts, but how you walk matters. In 2012, psychology professor Angela Kay Liang and her colleagues tested three groups of people. One group walked around in rectangles while completing a mental test, another group walked around freely, and the last group sat down while taking the test. The free walking group outperformed the other two groups, and other studies have shown that free walking results in improvements in fluency, flexibility, and originality of thinking. And here's an interesting one, taking a shower. If you've ever worked on a problem for hours only to come up with a solution while showering, that's your default mode network at work. Have you ever noticed when you're taking a shower, you're more creative? I took six showers this morning just to this episode for you. As you lost track of time and stayed in the shower for maybe 30 minutes instead of five minutes, your brain was relishing some much needed rest and allowed for the default mode network to step in. But there is a downside of an overactive default mode network. While there are many benefits to an active default mode network, there is also a downside when it becomes too active. An overly active default mode network can lead to excessive rumination that culminates in mulling over worries, past mistakes, and anxieties over the future. Luckily, there are two simple ways to calm down the network and bring yourself back into harmony and into balance. One of these is one of my favorites, meditation. Research has shown that relaxation techniques such as mindfulness, meditation, and even deep breathing can quiet the default mode network and boost well-being through decreased inflammation and stress. Another way is to cultivate the sensation of awe. Experiencing awe shifts your focus from everyday worrying to seeing the big picture and reminds us that most of our daily repetitive worries that are often linked to negative thought patterns are actually insignificant in the grand scheme of things. The easiest way to cultivate this sensation is to spend time in my opinion in nature and experience its vastness and greatness by watching something simple like a sunset or a moonrise or swimming in the ocean or hiking wherever you are. Maybe you have a hill or your favorite mountain top to learn more about awe, how to cultivate it and define it. out about its many benefits. Listen to our previous episode number 374, where we talk about the extensive research on this subject. We now know that focus is important in improving how we think. But for optimal brain training, we need to both focus and unfocus. So learn how to work with your default mode network and build unfocused times into your day to take advantage of both types of intelligence. If you're already sleeping enough, at a walk, some nap time or day dreaming into your schedule. It takes time and organization, but the benefits, as always, are well worth it. Until next time, quick brains, remember to stay limitless.
