Americans’ bathroom phone habit now looks like one more way modern life quietly undermines our health while tech companies and regulators look the other way.
Story Snapshot
- New research links smartphone use on the toilet to a roughly 46% higher rate of hemorrhoids.
- Phone users tend to sit much longer, which raises pressure in rectal veins and likely drives the risk.
- Experts stress the problem is extended sitting time, not the phone’s screen itself.
- Guidelines now urge people to limit toilet sessions and leave phones outside the bathroom.
What the new hemorrhoid study actually found
Researchers at a major Boston hospital studied 125 adults who were already scheduled for colonoscopy and asked detailed questions about their toilet habits. About two-thirds said they use a smartphone while on the toilet. When doctors checked for hemorrhoids, phone users were about 46 percent more likely to have them than people who did not bring their phones into the bathroom. This higher risk held even after the team adjusted for age, sex, body weight, exercise, fiber intake, and straining.
The same study found a clear difference in how long people sat. Roughly 37 percent of smartphone users reported spending more than five minutes per bathroom visit, compared with about 7 percent of non-users. That means phone users were about five times more likely to linger beyond the five-minute mark. The authors describe their results as an association, not proof of direct cause, but they say longer sitting appears to be the key way phone scrolling ties into hemorrhoid problems.
How longer toilet time can lead to hemorrhoids
Hemorrhoids happen when veins in and around the rectum swell and weaken under pressure. Colorectal specialists say sitting on the toilet too long increases that pressure, especially if you also strain. One surgeon explains that “it’s not the actual act of using a smartphone that is the problem,” but the prolonged sitting that “can definitely lead to hemorrhoid problems.” Normal bowel movements usually take just a few minutes. When scrolling keeps you seated for ten or fifteen minutes, those veins stay under stress the entire time.
Several medical explainers point out that toilets are worse than regular chairs because of posture and support. Standard toilets place the anus below the rest of the body with the hips bent, which can make blood pool more easily in rectal veins. If you are also slightly leaning forward to stare at a phone, the position can add even more downward pressure. Over time, repeated long sessions can stretch the vein walls, making them more likely to swell, itch, and bleed. Doctors say this same risk exists whether people read a book, scroll social media, or just sit and think; the common factor is time.
Where the evidence is strong, and where it is limited
The key evidence comes from one cross-sectional study, meaning it captured habits and hemorrhoid status at a single point in time. The research is peer-reviewed and used colonoscopy findings, not just self-report, which makes the outcome data stronger. It also controlled for several other risk factors in its analysis, which helps rule out simple explanations like “phone users just exercise less” or “they eat less fiber.” On that basis, many outlets now repeat the 46 percent figure and warn against bathroom scrolling.
Still, the study cannot prove that phones themselves “cause” hemorrhoids. It shows phone use, longer sitting, and hemorrhoids go together, but it cannot say which came first or whether another habit drives all three. Health reporters and clinicians highlight this limit and stress that the likely villain is how long people sit, not the specific act of swiping a touchscreen. This pattern fits a broader trend where modest observational findings quickly turn into simple public rules, even when deeper questions about cause remain open. Readers should see the 46 percent number as a warning signal, not as a final verdict.
Practical takeaways for everyday bathroom habits
Despite these limits, digestive experts treat shorter toilet time as low-risk, high-benefit advice. One clinician says you should really only sit as long as you have a clear urge and leave if nothing happens after a couple minutes. Many recommend aiming to finish bowel movements within one to fifteen minutes and avoiding extended sitting and straining. New guidelines for constipation and hemorrhoid prevention now tell people to stop using phones on the toilet and to focus instead on more fiber and water in their daily diet.
For many people, bathroom scrolling is part of a larger pattern of tech overuse and delayed self-care. The same phones that keep people seated on toilets also keep them up late, stressed, and less active. In that sense, this study is not just about hemorrhoids; it is one more case where everyday technology, backed by powerful companies, nudges people toward habits that harm health while government and public systems struggle to respond. Leaving the phone outside the bathroom is a small step, but it pushes back against that wider unhealthy drift.
