Smartwatches Track Our Health. Smart Toilets, Too.
Commodes that measure your health and might even diagnose Covid-19 are in the works.

The next frontier of at-home health tracking is flush with data: the toilet.
Researchers and companies are developing high-tech toilets that go beyond adding smart speakers or a heated seat. These smart facilities are designed to look out for signs of gastrointestinal disease, monitor blood pressure or tell you that you need to eat more fish, all from the comfort of your personal throne.
“All of the things that have come with smartwatches and phones, you can imagine that on another scale,” says Joshua Coon, a bioanalytical chemist at the University of Wisconsin-Madison and Morgridge Institute for Research, who published a 2019 study exploring the potential of continuously monitoring a person’s health by looking at molecules in their urine samples. “You could really start to understand disease risk.”
Doctors have long used fecal and urine samples for clues to people’s health, but there has been a renewed interest in recent years as scientists have begun to better understand how the microbes in our gut influence our well-being. In the Covid-19 pandemic, more communities launched wastewater surveillance initiatives, enabling health officials to hunt for early signs of the virus in cities and neighbourhoods and track its spread.
Some researchers want to harness that wealth of information on the individual level and have come up with models to peer into the toilet bowl remotely. Some smart toilets are geared toward helping doctors monitor patients with chronic conditions or heightened risk for certain diseases, whereas other companies aim to sell the toilets—with price tags in the hundreds or thousands of dollars—directly to consumers as a tool to track or improve their own health and wellness.
Researchers at Stanford School of Medicine have outfitted a toilet bowl with cameras and trained a machine-learning algorithm to analyze the waste against a diagnostic chart. The toilet can also track the flow, colour and volume of urine. It is equipped with a urine test strip similar to a pregnancy test that detects specific molecules that can provide insight into a person’s health. To tell users apart, the toilet has both a fingerprint scan when a person flushes and a scan of their anus’s characteristics, or an anal print.
The Stanford team has signed an agreement with Izen, a Korean toilet maker, to manufacture the toilet. They hope to have working prototypes that can be used in clinical trials by the end of this year, says Seung-min Park, who leads the project, which was started by Sanjiv Gambhir, the former chair of radiology at Stanford, who died in 2020.
Another prototype smart toilet developed at Duke University also deploys cameras and machine learning to analyze waste after it has been flushed. It uses other sensors to capture consistency, presence of blood and specific proteins and extracts a small vial of stool that can be shipped off to a lab for further analysis. The smart toilet, along with others in development, is designed to connect with an app on a person’s phone.
“[You could] get personalized alerts for having more fibre or avoiding certain foods to avoid flare-ups,” says Sonia Grego, founder of the Duke Smart Toilet Lab and Coprata Inc., a startup that she and two other team members launched in 2021 to commercialize the technology.
A remote smart toilet could help doctors monitor patients with chronic conditions such as irritable bowel syndrome or spot early signs of disease, says Dr. Grego. Another plus is that it could allow for frequent measurements that can be tracked over time, which could be a more effective, non-invasive way to track certain metrics and quickly identify and flag changes than sporadic readings during doctor’s visits.
“What your blood pressure is at 2 p.m. on a Tuesday doesn’t matter. To get that information with real trends behind it is super valuable,” says Austin McChord, the chief executive of Casana, a home-health monitoring startup working on a toilet seat that can measure vital signs including blood pressure, blood-oxygen levels or heart rate.
The company said in February that it had raised $14 million in Series A funding and is working toward getting clearance from the Food and Drug Administration for the seat to measure a handful of vital signs, Mr. McChord says.
Some diagnostics experts argue that the value in a smart toilet would come from being able to analyze the molecular substances in patient samples and that other devices, including smartwatches, can easily monitor blood pressure and heart rate. Mr. McChord and others working on smart-toilet technology say that advantages to using a toilet seat over another wearable device are adherence and ease-of-use.
“If you want someone to use something, it has to be incredibly simple,” says Chad Adams, president and chief executive of the company Medic.Life, which is working to get FDA clearance for its Medic.Lav smart toilet. “Everybody has to go to the bathroom.”
Medic.Life first plans to sell its toilet to assisted living facilities, where it could help track residents’ vital signs, bodyweight or even the sugar or sodium levels in their urine, among other metrics, before expanding to general consumers. A future version for assisted living facilities, pharmacies and healthcare providers would diagnose certain infections, such as urinary-tract infections or Covid-19.
Google LLC also has a patent for a toilet seat that doubles as a cardiovascular monitor, filed in 2015, although it isn’t clear whether the company is pursuing the project. Google Health declined to comment. Toilet maker Toto is designing a toilet that could analyze people’s waste and provide recommendations to improve wellness, such as drinking more water or adding something to their diets. The company anticipates launching the toilet in the next several years.
Toilet makers say that their products can provide medical-grade results for some vital signs and urine tests, but a smart toilet that can analyze the broader chemical makeup of waste is likely further off. Developers will have to work out how to prepare samples for analysis and refill the chemicals needed to run the reaction, as well as make the toilet cost-effective, biochemists and diagnostic experts say.
Another key barrier is privacy. A 300-person survey conducted by the Stanford team found that one third of respondents were uncomfortable with the concept of a smart toilet that collects health data, with many citing privacy as a chief concern. Respondents were especially uncomfortable with the camera-based approach. More than half, however, were at least somewhat comfortable with a smart toilet.
“I have now heard every toilet pun or joke you can imagine,” Casana’s Mr. McChord says. “A toilet seat is something that everyone is going to giggle about, but you have that moment to explain what it really does, and people really do see the value there.”

The latest trend in wellness travel is somewhere between a spa trip and a doctor’s appointment

For some vacationers, the ideal getaway involves $1,200 ozone therapy or an $1,800 early-detection cancer test.
Call it the longevity vacation. People who are fixated on optimising their personal health are pursuing travel activities that they hope will help them stay healthier for longer. It is part of a broader interest in longevity that often extends beyond traditional medicine . These costly trips and treatments are rising in popularity as money pours into the global wellness travel market.
At high-end resorts, guests can now find biological age testing, poolside vitamin IV drips, and stem-cell therapy. Prices can range from hundreds of dollars for shots and drips to tens of thousands for more invasive procedures, which go well beyond standard wellness offerings like yoga, massages or facials.
Some longevity-inspired trips focus on treatments, while others focus more on social and lifestyle changes. This includes programs that promise to teach travellers the secrets of centenarians .
Mark Blaskovich, 66 years old, spent $4,500 on a five-night trip last year centred on lessons from the world’s “Blue Zones,” places including Sardinia, Italy, and Okinawa, Japan, where a high number of people live for at least 100 years. Blaskovich says he wanted to get on a healthier path as he started to feel the effects of ageing.
He chose a retreat at Modern Elder Academy in Mexico, where he attended workshops detailing the power of supportive relationships, embracing a plant-based diet and incorporating natural movement into his daily life.
“I’ve been interested in longevity and trying to figure out how to live longer and live healthier,” says Blaskovich.
Vitamins and ozone
When Christy Menzies noticed nurses behind a curtained-off area at the Four Seasons Resort Maui in Hawaii on a family vacation in 2022, she assumed it might be Covid-19 testing. They were actually injecting guests with vitamin B12.
Menzies, 40, who runs a travel agency, escaped to the longevity clinic between trips to the beach, pool and kids’ club, where she reclined in a leather chair, and received a 30-minute vitamin IV infusion.
“You’re making investments in your wellness, your health, your body,” says Menzies, who adds that she felt more energised afterward.
The resort has been expanding its offerings since opening a longevity centre in 2021. A multi-day treatment package including ozone therapy, stem-cell therapy and a “fountain of youth” infusion, costs $44,000. Roughly half a dozen guests have shelled out for that package since it made its debut last year, according to Pat Makozak, the resort’s senior spa director. Guests can also opt for an early-detection cancer blood test for $1,800.
The ozone therapy, which involves withdrawing blood, dissolving ozone gas into it, and reintroducing it into the body through an IV, is particularly popular, says Makozak. The procedure is typically administered by a registered nurse, takes upward of an hour and costs $1,200.
Longevity vacationers are helping to fuel the global wellness tourism market, which is expected to surpass $1 trillion in 2024, up from $439 billion in 2012, according to the nonprofit Global Wellness Institute. About 13% of U.S. travellers took part in spa or wellness activities while traveling in the past 12 months, according to a 2023 survey from market-research group Phocuswright.
Canyon Ranch, which has multiple wellness resorts across the country, earlier this year introduced a five-night “Longevity Life” program, starting at $6,750, that includes health-span coaching, bone-density scans and longevity-focused sessions on spirituality and nutrition.
The idea is that people will return for an evaluation regularly to monitor progress, says Mark Kovacs, the vice president of health and performance.
What doctors say
Doctors preach caution, noting many of these treatments are unlikely to have been approved by the Food and Drug Administration, producing a placebo effect at best and carrying the potential for harm at worst. Procedures that involve puncturing the skin, such as ozone therapy or an IV drip, risk possible infection, contamination and drug interactions.
“Right now there isn’t a single proven treatment that would prolong the life of someone who’s already healthy,” says Dr. Mark Loafman, a family-medicine doctor in Chicago. “If it sounds too good to be true, it probably is.”
Some studies on certain noninvasive wellness treatments, like saunas or cold plunges , do suggest they may help people feel less stressed, or provide some temporary pain relief or sleep improvement.
Linda True, a policy analyst in San Francisco, spent a day at RAKxa, a wellness retreat on a visit to family in Thailand in February. True, 46, declined the more medical-sounding offerings, like an IV drip, and opted for a traditional style of Thai massage that involved fire and is touted as a “detoxification therapy.”
“People want to spend money on things that they feel might be doing good,” says Dr. Tamsin Lewis, medical adviser at RoseBar Longevity at Six Senses Ibiza, a longevity club that opened last year, whose menu includes offerings such as cryotherapy, infrared sauna and a “Longevity Boost” IV.
RoseBar says there is good evidence that reducing stress contributes to longevity, and Lewis says she doesn’t offer false promises about treatments’ efficacy . Kovacs says Canyon Ranch uses the latest science and personal data to help make evidence-based recommendations.
Jaclyn Sienna India owns a membership-based, ultra luxury travel company that serves people whose net worth exceeds $100 million, many of whom give priority to longevity, she says. She has planned trips for clients to Blue Zones, where there are a large number of centenarians. On one in February, her company arranged a $250,000 weeklong stay for a family of three to Okinawa that included daily meditation, therapeutic massages and cooking classes, she says.
India says keeping up with a longevity-focused lifestyle requires more than one treatment and is cost-prohibitive for most people.
Doctors say travellers may be more likely to glean health benefits from focusing on a common vacation goal : just relaxing.
Dr. Karen Studer, a physician and assistant professor of preventive medicine at Loma Linda University Health says lowering your stress levels is linked to myriad short- and long-term health benefits.
“It may be what you’re getting from these expensive treatments is just a natural effect of going on vacation, decreasing stress, eating better and exercising more.”
