How Promoting Handwashing Got One 19th Century Doctor Institutionalized

Regardless of how often we actually do it, it's common knowledge that washing our hands before eating, after coughing, and after using the bathroom is good for us. But the connection between handwashing and health wasn't always accepted as fact. As Danielle Bainbridge explains in the PBS web series Origin of Everything, the first doctor to campaign for cleanliness in hospitals was not only shunned by other medical professionals, but ended up in an insane asylum.

Prior to the 19th century, handwashing primarily existed in the context of religious ceremonies and practices. It plays a role in Christianity, Islam, Judaism, Sikhism, and Buddhism in some form or another. But washing up to stop the spread of disease wasn't really a thing for most of history. People weren't aware of germs, so instead of microbes, they blamed illness on everything from demons to bad air.

Then, in 1846, a Hungarian doctor named Ignaz Semmelweis made a breakthrough observation. He noticed that women giving birth with the help of midwives were less likely to die than those treated by doctors. He determined that because doctors were also performing autopsies on victims of puerperal fever (a bacterial infection also known as childbed fever), they were somehow spreading the disease to their other patients. Semmelweis started promoting handwashing and instrument sterilization in his clinic, and the spread of puerperal fever dropped as a result.

Despite the evidence to support his theory, his peers in the medical community weren't keen on the idea of blaming patient deaths on doctors. Partly due to his commitment to the controversial theory, Semmelweis was shunned from his field. He suffered a mental breakdown and ended up in a mental hospital, where he died a few weeks later.

Germ theory did eventually become more mainstream as the century progressed, and washing hands as a way to kill unseen pathogens started gaining popularity. Even so, it wasn't until the 1980s that the CDC released the first official guidelines instructing people on best handwashing practices.

If this story suddenly has you in the mood to practice good hygiene, here's the best way to wash your hands, according to experts.

Netherlands Officials Want to Pay Residents to Bike to Work

Thinking about relocating to the Netherlands? You might also want to bring a bike. Government officials are looking to compensate residents for helping solve their traffic congestion problem and they want businesses to pay residents to bike to work, as The Independent reports.

Owing to automobile logjams on roadways that keep drivers stuck in their cars and cost the economy billions of euros annually, Dutch deputy infrastructure minister Stientje van Veldhoven recently told media that she's endorsing a program that would pay employees 19 cents for every kilometer (0.6 miles) they bike to work.

That doesn't sound like very much, but perhaps citizens who need to trek several miles each way would appreciate the cumulative boost in their weekly paychecks. For employers, the benefit would be a healthier workforce that might take fewer sick days and reduce parking needs.

Veldhoven says she also plans on designing a program that would assist employers in supplying workers with bicycles. The goal is to have 200,000 people opting for manual transportation over cars. If the program proceeds, it might find a receptive population. The Netherlands is already home to 22.5 million bikes, more than the 17.1 million people living there. In Amsterdam, a quarter of residents bike to work.

There's no timeline for implementing the pay-to-bike plan, but early trial studies indicate that the expense might not have to be a long-term prospect. Study subjects continued to bike to work even after the financial rewards stopped.

New Health-Monitoring Litter Box Could Save You a Trip to the Vet

Unsure if your cat is sick or just acting aloof per usual? A “smart toilet” for your fur baby could help you decide whether a trip to the vet is really necessary.

Enter the Pet Care Monitor: More than a litter box, the receptacle is designed to analyze cat urine for health issues, The Asahi Shimbun in Tokyo reports. Created by the Japan-based Sharp Corporation—better known for consumer electronics such as TVs, mobile phones, and the world's first LCD calculator—the product will be available for purchase on the company’s website starting July 30 (although shipping limitations may apply).

Sensors embedded in the monitor can measure your cat’s weight and urine volume, as well as the frequency and duration of toilet trips. That information is then analyzed by an AI program that compares it to data gleaned from a joint study between Sharp Corp and Tottori University in Japan. If there are any red flags, a report will be sent directly to your smartphone via an application called Cocoro Pet. The monitor could be especially useful for keeping an eye on cats with a history of kidney and urinary tract problems.

If you have several cats, the company offers sensors to identify each pet, allowing separate data sets to be collected and analyzed. (Each smart litter box can record the data of up to three cats.)

The Pet Care Monitor costs about $225, and there’s an additional monthly fee of roughly $3 for the service. Sharp Corporation says it will continue developing health products for pets, and it has already created a leg sensor that can tell if a dog is nervous by measuring its heart and respiratory rates.
