Author Vybarr Cregan-Reid discusses how economic eras shaped the human body. The podcast explores negative effects of sedentary lifestyles and screen time, impact of settling and the agricultural revolution, harmful effects of sitting, benefits of movement breaks, and the importance of mindset shift to combat sedentary lifestyles.
Our bodies have adapted to sedentary work and efficiency throughout history.
Taking short movement breaks every half hour can offset the negative impacts of sitting and improve overall health.
Deep dives
The Discovery of Animal Electricity
In the late 1780s, Italian doctor Luigi Galvani discovered that animal muscles could be made to contract when exposed to an electrical circuit. This led to the hypothesis of animal electricity, the idea that animals store electricity in their cells like a battery. Galvani's findings were later questioned by Alessandro Volta, who determined that the contraction of muscles was caused by a circuit between different metals, creating an electrical current. Volta's experiments ultimately led to the invention of the battery.
The Evolution of Sedentary Behavior
From the Paleolithic era to the present, human work and technology have shaped our bodies and habits. As we transitioned from a hunter-gatherer lifestyle to settled agriculture and industrialization, our bodies adapted to sedentary work and efficiency. With the advent of technology and modern conveniences, our daily movements have decreased significantly, leading to an increase in health problems associated with a lack of physical activity.
The Importance of Movement Breaks
Research has shown that prolonged sitting and sedentary behavior can have detrimental effects on our health, regardless of regular exercise. Studies suggest that taking short movement breaks every half hour can offset the negative impact of sitting. These breaks can involve light walking or other gentle movement, and are found to lower blood sugar spikes, reduce blood pressure, increase energy levels, and improve mood. Encouraging movement breaks in workplaces can lead to more productive employees and contribute to a culture change towards a healthier lifestyle.
This is an episode we think you might enjoy of Body Electric. TED Radio Hour host Manoush Zomorodi investigates the relationship between our technology and our bodies and asks: How are we physically adapting to meet the demands of the Information Age? Why do so many of us feel utterly drained after a day spent attached to our devices?
