Main idea

If you are reading this while sitting on the toilet, you may want to finish quickly. A new American study shows that using a smartphone in the lavatory (厕所) raises the chance of getting haemorrhoids (痔疮) by almost half.

提出警示——在厕所使用智能手机会增加患痔疮的风险。

Two-thirds of the volunteers admitted that they took a smartphone into the toilet. These users were younger and spent much longer on the pan: 37 % of them sat for more than five minutes, compared with only 7 % of non-users. Statistical analysis showed that phone use itself, rather than straining, was linked to a 46 % higher risk of piles. Reading news or checking social media were the commonest activities.

The results appear in the journal PLOS One. Until further studies appear, the cheapest preventive medicine may be a simple rule: no phones on the throne.
