Historian Laine Nooney discusses how the computer revolution changed our bodies. The importance of breaks and physical activity on productivity. Taking movement breaks every half hour decreased blood sugar levels. Sitting all day led to worse mood, but walking breaks reduced anxiety and depressive symptoms.
Regular movement breaks throughout the day can significantly reduce blood sugar levels and cut the risk of developing diabetes.
The introduction of personal computers in the workplace led to unique physical ailments and stress postures, highlighting the need for ergonomic design.

The Impact of Sedentary Work on Physical Health
Sitting for extended periods of time while working on a computer can have detrimental effects on our physical health. Studies have shown that regular movement breaks throughout the day can significantly reduce blood sugar levels and cut the risk of developing diabetes. Additionally, taking breaks and incorporating short walks can improve mood, reduce fatigue, and increase overall energy levels. The sedentary nature of many jobs, which require digital skills, contributes to a lifestyle that is harmful to our bodies. Awareness of the negative effects of sedentary work and the importance of incorporating movement throughout the day is crucial.
The Historical Impact of Computers on the Human Body
The introduction of personal computers in the workplace in the 1980s brought about a significant shift in labor dynamics and had a profound impact on the human body. The design and use of computers led to the development of various physical ailments and stress postures not seen before. From extended sitting to strain on wrists, hands, fingers, and elbows, as well as specific head and neck positions, the bodily demands of using computers were unique and often harmful. The rise of laptops further exacerbated these issues, resulting in increased discomfort and long-term physical consequences.
The Benefits of Regular Movement Breaks
Engaging in regular movement breaks throughout the day has shown to have numerous benefits for both physical and mental well-being. Studies have found that incorporating short walks and breaks from sedentary work can lower blood sugar levels, reduce anxiety and depression, alleviate fatigue, and enhance concentration. While taking breaks may seem counterintuitive to workplace culture, the immediate positive effects on productivity and overall mood make it a worthwhile practice. Recognizing the importance of giving the body and mind regular breaks can lead to improved health and well-being.
In part two: host Manoush Zomorodi delves into how we met and fell hard for the personal computer—and why we continue to have this committed, yet tortuous relationship. We hear from historian Laine Nooney on how the computer revolution forever changed the way we use our bodies at work, at school and at home.
Manoush also visits the Exercise Testing Laboratory at Columbia University Medical Center where researchers collect data on how her body responds to a day of sitting compared to a day of constant movement breaks.
