When you shower you are getting grounded.
The positive charge that builds-up over time gets discharged. In modern life people are electrically isolated from earth usually by rubber soles and/or tires.
Increasing levels of electromagnetic radiation are probably making it even more critical to get grounded regularly.

Yes, this is good. Most people are electrically isolated from the earth all day with rubber shoes/tires. This causes a positive charge to build-up which has harmful effects.
Best is to step in running water.
