The latest restroom marvel in high-tech toilets from Japan should come with a health warning for hypochondriacs. The warning is that it doubles as a medical lab that can really spoil your day.
Japanese toilets have long and famously dominated the world of bathroom hygiene with their array of functions, from posterior shower jets to perfume bursts and noise-masking audio effects for the easily-embarrassed.
The latest "intelligent" model, manufactured by market leader Toto, goes a step further and isn't for the faint-hearted: it offers its users an instant health check-up every time they answer the call of nature.
Designed for the housing company Daiwa House with Japan's growing army of elderly in mind, it provides urine analysis, takes the user's blood pressure and body temperature, and measures their weight with an inbuilt floor scale.
"Our chairman had the idea when he was at a hospital and saw people waiting for health checks. He thought it would be better if they could do the health tests at home," says Akiho Suzuki, an architect at Daiwa House.
Toto's engineers developed a receptacle inside the basin to collect the urine for sugar content and temperature checks, and an armband to monitor blood pressure. The readout is displayed on a wall-mounted computer screen.
"With the current model, your data is sent automatically to your personal computer, and then you can email it to your doctor," said Suzuki.
