Discussion Japan TV show claims urinating while standing is not clean and can spread everywhere, experts recommend sitting

[Nightrider]

It is more clean to sit then stand

Men have a habit of uringing while standing up, even though it is cleaner to do so while sitting down.
The TBS channel 「この差って何ですか？」(KonoSataNanidesuka) did their own research into this

Their survey indicate that 73% of men urine while standing, then sitting

And the two most common reason
Reason 1 - Sitting is troublesome

I can't urine while sitting

So the show decide to do their own experiment, Using a liquid that glow in the dark

But where you aim is also important, so they have seperate into 4 location and color base too

And before experiment asking people what they aim for and why?

I am for yellow, because the back should block spray

I aim for water to stop spraying

Their survery result is 60% aim for red, 24% aim for yellow

So now the Experiment start first with red into the water

Turning off the light and can see it spray everywhere

Outside of toilet

On the floor

And the wall too

The show then brought in expert from Lion(Medical/cleaning company)
吉井和美

Total droplet that spray outside is 372 droplet

Men urine on average 7 time per day

So spray about 2600 droplet a day outside of toilet

Now if it is aim at back of toilet yellow target

Spray outside 7550 droplet

over 50000 droplet per day

Because the water will absorb majority of it, even if standing

Now what is the result if sitting?

Sitting will only have about 200 droplet, and they are all on the inside of the toilet

It is easier to clean too

And the best method to reduce splash is to float a piece of toilet paper in first

Which result in no outside or inside

Well that's certainly quite an extensive study they performed, and indeed it does seem as though men create an awful lot of splashback when urinating. I find it extremely doubtful that the vast majority will change their ways, however, so I wouldn't expect this study to result in much more than a "yeah, so what?" sort of response from most.
