We often think of addiction as something dramatic—alcohol, drugs, cigarettes. But according to Dr. Raphael Cuomo, author of Crave: The Hidden Biology of Addiction and Cancer, the most dangerous addiction is the one that feels normal.
Scrolling, binge-watching, endless notifications—these don’t come with warning labels. In fact, they’re encouraged, even celebrated.
But here’s the truth: every time we reach for our phone or lose ourselves in a screen, we leave behind what Dr. Cuomo calls “molecular scars.” The body records everything we repeat.
That means scrolling isn’t just a harmless habit; it’s a pattern that reshapes our biology.
Why Scrolling Feels Harmless
When we scroll, the brain’s dopamine system lights up. Each new post, each like, each video is a hit of novelty. At first, it feels good. But over time, the brain adapts.
The receptors become less sensitive, so we need more scrolling for the same feeling of relief. This is why a “quick check” can easily turn into 30 minutes or more.
Meanwhile, cortisol (the stress hormone) gets involved too. Notifications, newsfeeds, and constant input put the body into a subtle state of stress. The nervous system never fully relaxes.
Sleep is disrupted, attention becomes scattered, and the immune system shifts out of balance. The cost isn’t visible immediately—but it accumulates.

Women Over 50: Why It Matters More
For women over 50, this matters in a profound way. Our bodies are already navigating hormonal changes, shifting metabolism, and the natural stressors of midlife.
Add in the constant stimulation of screens, and the result is often heightened anxiety, poor sleep, weight gain, and brain fog. It’s not weakness; it’s chemistry.
What makes scrolling dangerous is exactly what makes it normal: everyone does it. But just because it’s common doesn’t mean it’s harmless.
My Experience
I’ve never considered myself an addictive person. I don’t drink much, I don’t smoke, and I live a healthy lifestyle. But scrolling? That one sneaks up on me.
On the rare occasions when I do get pulled in, I can feel the negative effects almost immediately—my mind feels restless, my body unsettled, and I lose the sense of calm I’ve worked so hard to create.
That’s why I limit it, but I also know how easy it is to slip.
What We Can Do
The empowering part of Dr. Cuomo’s message is that biology can change. The same way repetition wires us into compulsive scrolling, new rhythms such as walking, stretching, cooking, and meditating can rewire us back into balance.
The takeaway? Scrolling may feel normal, but normal isn’t always healthy. Every time we choose presence over distraction, we’re not just resisting temptation—we’re rewriting our biology in favor of clarity, resilience, and longevity.
If this message resonated with you and you’d like to dive deeper into the science behind it, I recommend Dr. Raphael Cuomo’s book Crave: The Hidden Biology of Addiction and Cancer. It’s eye-opening, empowering, and will change the way you think about habits, health, and longevity.
Crave: The Hidden Biology of Addiction and Cancer
Crave reveals how everyday habits, from sugar and screens to overwork and alcohol, leave measurable biological traces that increase cancer risk.
It reframes addiction as a central, modifiable factor in chronic disease, drawing on cutting-edge research in neuroscience, immunology, and public health.
