We use our smartphones just about everywhere, even in the bathroom, although we may not want to talk about that.

The cause and effect are clear. Caught up in news, games or social media, bathroom users stay seated on the throne longer, with research showing phone users tend to spend more than 5 minutes doing their business. The study says that hemorrhoids are associated with prolonged sitting on the toilet, as well as constipation and increased straining.
