手机让我们久坐不动，超越了终点线的束缚

Your bathroom scroll may be reshaping your body in ways you can’t feel, until it hurts.

你在厕所里的刷手机习惯，可能正在以你无法察觉的方式重塑身体，直到疼痛来临。

A new study finds that using a smartphone on the toilet is linked to a 46 percent higher risk of hemorrhoids, the painfully swollen veins in the rectum that send millions to clinics each year.

一项新研究发现，如厕时使用智能手机与痔疮风险增加46%有关。痔疮是直肠内疼痛性肿胀的静脉，每年让数百万人就医。

The culprit isn’t blue light or “dirty” screens, it’s time. Phones keep us seated long past the finish line.

罪魁祸首不是蓝光或“脏”屏幕，而是时间。手机让我们在马桶上坐得远超“完事”的时间。

Gastroenterologists at Beth Israel Deaconess Medical Center surveyed 125 adults undergoing colonoscopy.

贝斯以色列女执事医疗中心的胃肠病学家调查了125名接受结肠镜检查的成年人。

Two-thirds admitted to scrolling while seated, and those users lingered: 37 percent spent more than five minutes per visit, compared with just 7 percent of non-users.

三分之二的人承认会在如厕时刷手机，而这些使用者停留更久：37%的人每次花费超过5分钟，而非使用者只有7%。

After accounting for age, exercise, and fiber, phone use still tracked with higher hemorrhoid risk.

在调整了年龄、运动和膳食纤维等因素后，手机使用依然与痔疮风险升高相关。

Hemorrhoids aren’t foreign invaders, they’re normal vascular cushions that help seal the canal and guide stool.

痔疮并非外来“敌人”，它们本是正常的血管垫，帮助封闭肛管并引导粪便排出。

Trouble begins when tissue engorges and slips, leading to bleeding, itching, and pain.

问题出在组织充血并下移时，会引起出血、瘙痒和疼痛。

Classic wisdom blames straining and low fiber, but evidence is converging on another driver, prolonged sitting on a seat that leaves the pelvic floor unsupported, increasing pressure on delicate vessels.

传统观点认为痔疮源于排便用力和膳食纤维不足，但新的证据指向另一原因：长时间坐在马桶上，使盆底缺乏支撑，增加了脆弱血管的压力。

Smartphones act like glue. News feeds, social media, and messages stretch a quick stop into an unintended sit-in, amplifying pressure minute by minute.

智能手机就像胶水。新闻推送、社交媒体和消息把一次短暂停留拖成“静坐示威”，每一分钟都在加大压力。

Notably, the study did not find an independent link between straining and hemorrhoids in phone users, hinting that duration may matter more than effort.

值得注意的是，研究并未发现手机使用者的排便用力与痔疮有独立关联，这暗示时间可能比用力更重要。

This was a small, cross-sectional study, so it shows association, not causation.

这是一项小规模的横断面研究，因此只显示相关性，而非因果关系。

Still, the practical guidance is simple and low-risk: answer nature’s call, then stand up.

不过，实用的建议简单且低风险：有便意就如厕，完事就起身。

Aim for five minutes or less, build fiber and hydration into your day, and consider leaving the phone outside the door.

尽量控制在5分钟以内，日常摄入足够纤维和水分，并考虑把手机留在厕所外。

As senior author Trisha Pasricha puts it, going number two should be your number one priority, not scrolling.

正如资深作者 Trisha Pasricha 所说：“排便应该是第一优先，而不是刷手机。”
