You've heard that too much time online is bad for your mental health, but what is it doing to your body? In this energizing talk, journalist and author Manoush Zomorodi explains how tech habits (including sitting all day) affect your physical health, from making you feel exhausted to raising rates of chronic illness. With early results from a 20,000-person experiment, she shares a practical solution to go from "wired and tired" to feeling healthier and more productive.

Sitting all day is killing you — here's what to do about it

Journalist, host of NPR's "TED Radio Hour"

Spending long hours sitting in front of screens leaves people not just mentally but physically depleted, fueling a spike in chronic illnesses. A 19-year-old today moves as little as a 60-year-old did two decades ago, and rates of type 2 diabetes in young people have doubled. Yet just five minutes of gentle movement every half hour can dramatically improve blood sugar, blood pressure, and energy. Making small, regular movement breaks part of daily routines helps people feel better and stay productive, even in a world built around screens.

Digital Lives Are Draining Our Bodies—Movement Is the Antidote

Modern life keeps people glued to screens, draining energy and harming bodies. Studies show that even young adults now move as little as seniors, contributing to soaring rates of chronic illness globally. Remarkably, just five minutes of gentle activity every half hour can cut blood sugar, lower blood pressure, and boost mood and focus. These simple movement breaks are both achievable and powerful, sparking positive change without sacrificing productivity.
