New Study Reveals a Major Side Effect of Walking More

Walking, a simple and accessible physical activity, has been extensively studied for its myriad health benefits. Recent research has further illuminated the significant impacts of walking on various aspects of our health and well-being.

This article delves into these findings, highlighting the major side effects of walking more, based on a variety of recent studies.

1. Impact on Sleep and Lifespan

A notable study utilizing data from the UK Biobank examined the joint effects of sleep and physical activity on lifespan. The research analyzed health data from over 380,000 people, focusing on their exercise levels and sleep quality.

The study found a strong correlation between poor sleep, lack of exercise, and shorter lifespan. Notably, brisk walking for about 2.5 hours per week appeared to counteract some of the health risks associated with poor sleep, including the risk of early death.

This highlights the integral role of walking in improving sleep quality and extending lifespan (source: Eat This Not That).

2. Enhancing Brain Health

Another study explored the effect of physical activities like walking on brain health, particularly focusing on white matter, which connects nerve cells in the brain.

In this study, older adults who engaged in brisk walking showed significant improvements in memory skills and white matter health, surpassing those who participated in other forms of exercise like dancing.

This finding emphasizes walking’s unique benefit in maintaining and improving brain health in later life (source: Eat This Not That).

3. Boosting Creativity and Positivity

Further research has linked walking with enhanced creativity and positive mood. Regular physical activities, including walking, are associated with higher levels of creativity and subjective well-being.

The act of walking, requiring minimal conscious effort, allows the mind to wander and generate innovative ideas and insights, establishing a connection between physical movement and a fertile, healthy brain (source: Eat This Not That).

4. Mitochondrial Function and Metabolism

A study by Oregon State University revealed that even moderate-intensity exercises like brisk walking can have a profound impact on mitochondrial function, which is crucial for metabolism.

This research, focusing on sedentary individuals, found that moderate exercise led to increased burning of fat and sugar-based fuels in the mitochondria, highlighting the importance of walking in combating obesity and metabolic disorders (source: Eat This Not That).

5. Walking and Sense of Purpose

An intriguing aspect of walking is its connection to a sense of purpose in life. A study led by researchers at Harvard University and the University of Warwick found that physical activity, including walking, is linked to stronger feelings of purpose.

This virtuous cycle suggests that people who engage in physical activities like walking not only feel a greater sense of purpose but are also propelled to maintain their active lifestyles.

This connection between physical activity and psychological well-being underlines the comprehensive benefits of walking (source: Eat This Not That).


Walking, often underestimated, emerges as a powerful tool for improving overall health and well-being. Its impacts span across physical, mental, and emotional health, making it a highly recommended activity for people of all ages.

Whether it’s enhancing brain function, extending lifespan, boosting creativity, improving metabolic health, or fostering a sense of purpose, walking proves to be an accessible and effective way to enhance quality of life.

Incorporating walking into daily routines, whether through brisk morning walks, lunchtime strolls, or evening hikes, can lead to profound health benefits. As these studies suggest, the path to a healthier, more fulfilling life could be as simple as taking a walk.
