In Praise of Walking

The book "In Praise of Walking" by neuroscientist Shane O'Mara invites us on a fascinating journey of discovery into the beneficial effects of walking on the body and brain. The author reveals how evolution gave us the ability to walk, allowing us to migrate and populate different parts of the world. He explains how walking benefits our muscles, improves posture, and helps maintain healthy organs. In addition, walking can slow the aging process of the brain, improve mood and reduce stress. Shane O'Mara details how our brain and nervous system provide balance and orientation in space through what he calls "internal GPS". He also emphasizes the importance of walking for our creativity and social cohesion. The book is not only about the physical benefits of walking, but also its impact on mental health and overall quality of life. O'Mara urges us to appreciate this common but extremely beneficial activity more and begin to integrate it into our daily lives. By taking us through the historical and scientific aspects of walking, the author reminds us that it's time to stand up, start walking, and discover a happier, healthier, and more creative version of ourselves.

Walking is one of the most natural and beneficial activities we can do for our bodies and minds. Scientists and experts repeatedly stress that regular walking has a positive effect on many aspects of our health. To better understand this phenomenon, let's break down how walking slows down the aging process of the brain, improves mood, and relieves stress. One of the most significant benefits of walking is its ability to slow down the aging process of the brain. Neuroscientist Shane O'Mara states in the book that regular physical activity such as walking can promote neurogenesis - the process of creating new neurons. This phenomenon is particularly important in the hippocampus, the part of the brain responsible for memory and learning. Research shows that people who walk regularly have better cognitive function and a lower risk of developing neurodegenerative diseases such as Alzheimer's disease. Walking also has a significant impact on improving mood. When we move, our brains release endorphins, also known as happiness hormones, which reduce feelings of pain and improve our overall sense of well-being. In addition, regular walking increases levels of serotonin and dopamine - neurotransmitters that are key to mood regulation and feelings of well-being. The study found that people who regularly walked in the fresh air reported significant improvements in mood and lower levels of depressive symptoms. Stress is one of modern man's greatest enemies, and walking offers a simple and effective way to reduce it. Walking increases blood flow to the brain, which helps reduce levels of cortisol, a hormone associated with stress. In addition, walking in a natural environment has an even stronger anti-stress effect. Research shows that walking in nature can reduce activity in areas of the brain associated with mental disorders such as anxiety and depression. As an example, an American study found that regular walking can reduce the risk of depression by up to 12%. Other research in the UK has shown that visiting natural environments leads to a significant improvement in mental wellbeing. In addition, a study in Ottawa, Canada, compared the effect of walking by a river and in a tunnel on the mood of participants and found that those who walked in nature reported much better moods. Walking is a simple, accessible and extremely effective activity that has huge benefits for our brain, mood and overall mental health. In today's world where sedentary lifestyles dominate, it is more important than ever to make time for regular walks that can help us maintain a healthy and happy life.

Walking as we know it today is the result of millions of years of evolutionary development, which has ensured its extraordinary reliability and efficiency. When we look at the mechanism of walking, we see a complex system that can function even in the most demanding conditions. This ability is encoded deep in our genes and manifests itself in every step we take. Research shows that the mechanisms that make walking possible have their roots in the ancient past. The movement-related genes we share with other species evolved when life on Earth was still underwater. These genes control important aspects of our nervous system and muscles, allowing us to maintain balance and move efficiently. For example, developmental biologists have found that stingrays and small mice share a number of genes that regulate their spinal cord, the location of their limbs, and related muscles and nerves. However, the human gait is unique and sets us apart from our closest relatives in the animal kingdom. For example, apes use all four limbs to move, whereas we evolved to walk upright on two legs. This evolutionary adaptation allowed us to travel great distances while carrying a variety of objects, which was crucial to our development as a species. Learning to walk is a challenging process for toddlers, requiring hundreds of falls and thousands of steps a day. Despite this apparent complexity, the mechanism of walking is extremely efficient. Robots that mimic human walking are still struggling to reach a level that even young children can manage. Our brains use a sophisticated system of inertial guidance to maintain balance and coordinate movements. This system constantly calibrates our position and ensures that our head remains parallel to the ground, which is critical for a stable gait. In addition to the brain, the spinal cord plays an important role in controlling the rhythmic patterns necessary for walking and other automatic bodily functions. Thus, walking is not only a physical activity, but also a complex neurobiological process that has been validated by evolution. This ability has allowed us to adapt to different environments and conditions, contributing to our success as a species. Every step we take is the result of a long evolutionary process that has ensured that walking is reliable and efficient.

Walking has a tremendously positive effect on our bodies, benefiting muscles, improving posture, and protecting and healing organs at the same time. Daily walking is a simple and natural way to keep your body in optimal condition. Regular walking strengthens the muscles of the whole body, especially the lower limbs, but also the muscles of the abdomen and back. These muscles are constantly engaged in work, which contributes to firming them and improving overall muscular endurance. Stronger muscles not only help with normal daily activities, but also reduce the risk of injury and pain that often come with weakened muscles and a sedentary lifestyle. Improved posture is another significant benefit of regular walking. When walking, the muscles of the torso are automatically engaged, which maintains proper spinal alignment. This activity naturally leads to better posture, which can help prevent back and neck pain. Research shows that people who walk regularly have better posture and fewer back pain problems compared to those who lead a sedentary lifestyle. Walking also significantly benefits our internal organs. Regular physical activity such as walking promotes cardiovascular health by improving blood flow and lowering blood pressure. This reduces the risk of heart disease and strokes. Additionally, walking promotes digestion and improves digestive tract function, which can prevent problems such as constipation or irritable bowel syndrome. Walking can also help regulate blood sugar levels, which is key to preventing and controlling type 2 diabetes. Studies have shown that people who walked for at least half an hour every day had a lower risk of developing the disease. Also, walking helps with weight management by promoting calorie burning and increasing metabolism. An example is a study that examined the effect of regular walking on the health of seniors. It found that seniors who walked at least 150 minutes a week had significantly better fitness and healthier hearts compared to those who walked less. These people also reported improved overall quality of life and fewer health problems. In conclusion, walking is an extremely effective and easy way to keep your body healthy and strong. It strengthens muscles, improves posture and has beneficial effects on our internal organs. This natural movement is essential for maintaining overall health and well-being without the need for special equipment or a gym membership. We just need to take the time to go for a walk to reap all these benefits.

When we walk, the brain's "internal GPS" is activated, a fascinating process that allows us to navigate through space and find our way even in unfamiliar surroundings. This mechanism is the result of evolution and is deeply rooted in our brain. Research by neuroscientist John O'Keefe has shown that the brain contains special neurons known as "place cells" that are activated when we move to familiar places. These cells are localized in the hippocampus, the area of the brain responsible for spatial memory and navigation. When we walk, these cells provide us with a map of our surroundings and help us determine where we are. In addition to place cells, there are other types of neurons that support our internal navigation. The directional cells of the head function as an internal compass that helps us keep our bearings. These cells are constantly active and respond to changes in the direction of our head. Another important type is the grid cells, which form a hexagonal pattern in the brain, providing us with a grid system for navigating through space. This system allows us to estimate distances and orient ourselves in relation to surrounding objects. Spatial navigation is not only crucial for orientation, but also supports our memory and cognitive abilities. As we walk, our brains are constantly updating and adjusting the map of our surroundings. This process improves our ability to remember places and routes, which is essential for daily functioning. Additionally, the activation of these neurons when we walk promotes neuroplasticity, which means our brain is constantly adapting and learning new things. One of the fascinating aspects of this "internal GPS" is that it works even without visual cues. Studies have shown that even people who are visually impaired or blindfolded are able to navigate and orient themselves in space similarly to people with normal vision. This proves that spatial navigation is deeply rooted in our nervous system and is not entirely dependent on vision. When we walk, peripheral cells are also activated and respond to boundaries and obstacles in our environment. These cells help us avoid obstacles and navigate complex environments such as crowded streets or unfamiliar places. Activation of this system is essential for safe and efficient walking, allowing us to move confidently and accident-free. Overall, our ability to walk and orient ourselves in space is the result of a complex interaction of different types of neurons and brain regions. This system, often likened to an "internal GPS," is crucial to our survival and daily functioning. Every step we take is supported by a sophisticated network of neurons that constantly track our location and direction, allowing us to safely and efficiently navigate our world.

Walking has tremendous positive effects not only on our bodies, but also on our minds and brains. This simple act of movement is a complex process that engages different systems and structures in our body, bringing many physical and mental benefits. When we walk, cardiovascular health is greatly improved, which directly affects brain function as well. Better blood flow means that the brain receives more oxygen and nutrients, which promotes optimal brain function. Research shows that regular physical activity, such as walking, improves cognitive function and reduces the risk of neurodegenerative diseases. People who walk regularly perform better on tests of memory and other mental abilities. The psychological benefits of walking are equally significant. Walking promotes the release of endorphins, which improve mood and reduce feelings of stress and anxiety. This natural antidepressant effect is particularly important in today's hectic world where stress is an everyday part of many people's lives. Regular walking can thus be an effective way to cope with stress and improve your emotional well-being. Another important aspect is that walking stimulates the production of new brain cells, which promotes neuroplasticity - the brain's ability to change and adapt to new information and experiences. This process is crucial for learning and memory, and regular walking thus contributes to maintaining and improving mental abilities throughout life. Walking also has a positive effect on creativity. When walking, the parts of the brain responsible for free association and creative thinking are activated. Many prominent thinkers and artists, such as Henry David Thoreau and William Wordsworth, used walking to stimulate their creativity. This phenomenon is supported by research showing that people are able to generate more ideas and solutions while walking than when sitting. In addition, walking has an important social dimension. Walking with friends or family can strengthen social bonds and improve overall well-being. Research shows that people who regularly participate in social walks have a better quality of life and are happier. This activity promotes a sense of belonging and community, which is important for mental health. Walking is therefore a holistic activity that has many benefits for the body, mind and brain. It promotes cardiovascular health, improves cognitive function, reduces stress and anxiety, fosters creativity, and strengthens social connections. Every step we take contributes to our overall well-being and quality of life.

Urban design and architecture should be designed to encourage walking, thereby improving the quality of life for residents and creating a healthier and more pleasant environment. Walking has many health and social benefits and it is therefore important that cities enable and encourage this activity. Cities should be designed to be accessible and convenient for pedestrians. This means that care should be taken to create walkways and paths that are safe, clean and attractive. Streets should be equipped with sufficient lighting, benches and greenery, which contribute to a pleasant walking experience. Examples of successful urban designs include places such as Copenhagen, where there are wide sidewalks, cycle paths and green spaces that encourage residents to walk and cycle. Locating amenities within walking distance is also an important element. Shops, schools, parks and public services should be close to residential areas so that residents do not have to use cars for everyday activities. This not only encourages walkability but also reduces traffic congestion and air pollution. For example, cities such as Amsterdam and Vancouver are trying to create neighbourhoods where everything you need is within walking distance, which greatly improves quality of life. The architecture of cities should also take into account the needs of the elderly and people with reduced mobility. Intersections should be designed to be safe and easy to navigate, and buildings should be equipped with ramps and elevators. Cities such as Singapore are known for their commitment to inclusive design, where accessibility for all ages and physical abilities is taken into account. Greenery is another key element in promoting walkability. Parks and green spaces not only provide places for rest and recreation, but also improve air quality and the overall environment. London with its Hyde Park or New York with Central Park are excellent examples of cities where green spaces play an important role in urban life. These green oases provide space for relaxation and physical activity, encouraging people to take regular walks. The benefits of urban design that encourages walking are immense. In addition to the health benefits for individuals, increased walkability leads to economic development as shops and services within walking distance are more frequently visited. Cities that are designed with pedestrians in mind exhibit greater economic activity and prosperity. This is evidenced by studies showing that stores in walkable areas have higher sales and cities with good walkability have lower health care costs. Last but not least, encouraging walkability through urban design helps create community spirit. Walkable neighborhoods encourage interaction between people, leading to stronger social ties and a better community. Cities like Barcelona are known for their lively streets where people meet and interact, fostering a sense of belonging and community. Overall, it is clear that the design and architecture of cities should encourage walkability to improve quality of life, promote health and create vibrant and thriving communities. This approach not only benefits individuals but also society as a whole, contributing to sustainable and inclusive urban development.
