A Canadian City Brings Fluoride Back to Its Drinking Water
The taste and smell won't change, but starting on Monday something was different about Calgary's water supply — fluoride is back in the taps across the city in Western Canada.
Fluoride, a mineral found in water, has widely established dental benefits shown to strengthen the tooth surface, or enamel, and help prevent decay.
Calgary stopped adding fluoride to its water supply in 2011, deciding that the cost to treat its system with the mineral outweighed the benefits.
But a push by city residents coupled by worsening oral health among children has led Calgary officials to reverse course.
'There's no question that it reduces cavities, which is not just a cosmetic issue, because poor dental health is associated with poor body health,' said Joe Schwarcz, a chemistry professor at McGill University in Montreal and director of a university office focused on debunking misinformation in science.
Fluoridation is largely viewed as one of the most significant and cost effective public health innovations of the last century. But fluoride has long been regarded with suspicion in some quarters and has been the target of conspiracy theories. In the 1950s critics of Communism in the United States claimed it was a mind-control tool to poison Americans.

Apple Watch's Noise App Know It Is Loud, Do You?
Apple Noise app alerting loud decibel reading It happens often. I walk down a street or sit in public when my Apple Watch taps my wrist. I glance down. The screen shows a mustard-yellow interface. The Noise app gently tells me that sound levels have exceeded 80 decibels. It is not an alarm, not a warning, just a discreet prompt: the environment is loud. That alert is brilliant in its design. It does not shout. It invites awareness. That is how behavior shifts, not by telling people what to do, but by showing them what they may not have noticed. In my first article in this Noise Economy series, I examined the growing toll that daily, unrecognized noise has on our physical and emotional health, and why society has largely ignored it. The second article looked at the quiet emergence of modern hearing protection and how a fringe safety item has evolved into a wellness accessory and lifestyle product. In this final piece, I want to explore what happens next. How do we move from awareness to responsibility? From recognition to action? What role do tools like Noise app by Apple play in helping us shift how we relate to sound?A New Kind of Awareness The Apple Hearing Study, conducted with the University of Michigan, revealed that nearly one in three people are exposed to daily sound levels that could harm their hearing. One in ten listens to headphone audio above 100 decibels. These are not anomalies. They reflect the reality of how we live. But this is not just about dangerous decibel spikes. The deeper issue is the steady, often unnoticed disruption of noise woven into every part of life, at home, work, and our social environments. At home, appliances hum, HVAC systems cycle, lawn mowers and leaf blowers buzz outside, and doorbells, phones, and televisions interrupt the quiet. At work, open offices carry constant conversation, ringing phones, and mechanical noise from printers, elevators, and ventilation systems. In social settings, the thud of weights and pounding music in gyms, the roar of traffic, and chatter in restaurants and airports all pile on. These sounds stack, hour after hour. The impact is not just loudness. It is fatigue, distraction, stress, and a quiet toll on long-term health. Most people are unaware of how much noise they live with, or what it might be doing to them. The brilliance of Apple's approach lies in the tone of the Noise app. That subtle yellow background, paired with a simple decibel readout, gives the user a moment to reflect. It is not red. It is not urgent. It is not panic-inducing. It is respectful. It reminds me of the Mona Lisa by Leonardo da Vinci in many ways. The painting is subtle, poised, and quietly powerful. You do not fully grasp its impact at a glance. Her smile, eyes, posture, all invite closer attention. The Noise app does the same. It encourages observation. You find yourself checking more often, paying closer attention, and asking: What do I do next?From Notification to Sound Footprint The Noise Economy is about rethinking how sound moves through our lives. We have long considered noise to be the cost of modernity. That may no longer be acceptable. This is not about silence. It is about clarity. The more we notice, the more we can choose when to filter, when to rest, when to protect, and when to fully engage. This shift invites us to consider a new personal measurement: the Sound Footprint. Inspired by the sustainability philosophy of Cradle to Cradle, this idea encourages us to think about how our environments, habits, and products affect our auditory well-being similarly to our energy or carbon output. The Cradle to Cradle approach challenges us to move beyond minimizing harm and toward designing for renewal. In their book, architects William McDonough and Michael Braungart share a striking example: when hired to redesign the massive Ford River Rouge plant, they transformed the factory's roof into a living ecosystem. Instead of installing a conventional roof, they introduced a vegetated 'green roof' that absorbed stormwater, reduced heat, and created a healthier environment for workers and the surrounding community. The redesign symbolized how a product or place can regenerate rather than deplete. That same principle applies to sound. The concept of a sound footprint borrows directly from this mindset. It is not just about turning down the volume. It asks how the environments we live and work in, homes, offices, stores, and digital spaces, can be designed to support, not strain, our sensory systems. Like the River Rouge roof, the goal is to give something back. With its gentle but informative alert, the Apple Noise app gives users the awareness to respond rather than react. It is a regenerative gesture in the world of personal tech. Quiet Mark works toward this same goal, helping people and businesses make smarter purchasing decisions. It certifies everyday products from kettles to vacuum cleaners that meet high standards for low-noise performance. That quiet becomes part of the value, not just a feature. These efforts show what is possible when we treat sound not as background static, but as part of how we care for health and design for life. When sound is seen as a resource, not a byproduct, we begin to build spaces that respect our full range of human perception. Sound Is the Next Wellness Frontier Many companies are already helping consumers think differently about sound. Quiet Mark certifies appliances and tools that meet low-noise performance standards. Dyson, long known for its powerful vacuums and hair dryers, continues to invest in noise mitigation, designing for performance without auditory fatigue. In parallel, a new class of hearing protection brands, including Loop, EarPeace, Eargasm, and EarFab, are turning earplugs into something both practical and aspirational. Loop's ring-shaped filters match outfits and environments. Eargasm builds for musicians and audiophiles. EarPeace delivers sleek, purpose-built options for venues and events. EarFab offers custom-fit comfort using app-based scanning. And increasingly, noise-canceling headphones and earbuds are becoming everyday tools for reducing ambient noise at home, in transit, or on the job, empowering users to regain control of their sound environment in real time. What was once purely functional is now a matter of style, wellness, and self-awareness. What Now? Each time my Apple Noise app delivers that mustard-yellow alert, I pause. Not in panic, but with intention. Can I step outside for a moment? Change my hearing device settings? Choose a quieter route? That simple prompt guides small decisions that, over time, build a more thoughtful relationship with noise. Businesses face the similar moment of choice. Will they start auditing the decibel levels in their retail stores, restaurants, gyms, and offices? Will they treat sound like they already manage lighting, air, and design as a core part of a healthy customer and employee experience? The next frontier is not just about alerts. It is about action and companies measuring their sound footprints and taking responsibility for the environments they create. Tools like Noise app by Apple do not fix noise. They do something more powerful: they help us see it. Once we see it, we cannot ignore it. A healthier noise economy does not demand silence. It asks for clarity and deliberate choices that protect attention, restore energy, and elevate the places where we live and work for my own sake and many others.

Crash Risk After Heart Device Implant Still Hard to Predict
TOPLINE: Models using driving and health data to predict 1-year crash risk after the implantation of a cardioverter-defibrillator showed poor discrimination between individuals who crashed motor vehicles and those who did not. However, such models with good calibration may help guide discussions about crash risk between clinicians and patients. METHODOLOGY: Clinical guidelines recommend temporarily ceasing driving after the implantation of a cardioverter-defibrillator; however, these restrictions can result in social isolation or loss of income. Empirical data to inform such driving restrictions are limited. Researchers in Canada used population-based administrative data and identified licensed drivers who had a first implantation of a cardioverter-defibrillator between 1998 and 2018 to estimate the subsequent risk for a motor vehicle crash using prediction models. The recipients were stratified into two cohorts according to the indication for their implants: those receiving implants for primary prevention of sudden cardiac death (n = 3652; median age, 66 years; 18% women) and those receiving implants for secondary prevention (n = 3408; median age, 65 years; 16% women). The outcome of interest was the involvement of the implant recipient as a driver in one or more crashes within the first year after the implantation procedure; crashes considered were those attended by police and/or involving an insurance claim. TAKEAWAY: Overall, 352 drivers (9.6%) in the primary prevention cohort and 270 drivers (7.9%) in the secondary prevention cohort were involved in crashes within the first year after implantation. The crash prediction models poorly distinguished between individuals who crashed and those who did not in both the primary and secondary prevention cohorts (c-statistics, 0.60 and 0.61, respectively). However, the models showed good calibration for both cohorts (calibration slopes, 1.14 and 1.07, respectively), suggesting that the models could be helpful in guiding discussions between clinicians and patients. In the primary prevention cohort, the top predictors of crash were male sex, number of crashes in the past year, and active vehicle insurance in the past year; in the secondary prevention cohort, the predictors were male sex, no history of seizure, active opioid prescriptions, and active vehicle insurance in the past year. IN PRACTICE: "Clinicians already use clinical intuition and common sense to identify patients at higher risk of SCI [sudden cardiac incapacitation] , reserving their most strident advice to avoid driving for the individuals they consider to be at highest risk," the researchers noted. "Using baseline health and driving data to formally predict post-implantation crash risk and personalize driving restrictions is a strategy that has the potential to strengthen this clinical practice, but our findings suggest this approach is not yet ready to deploy in clinical practice," they added. SOURCE: This study was led by John A. Staples of the University of British Columbia in Vancouver, British Columbia, Canada. It was published online on June 24, 2025, in Heart. LIMITATIONS: This study lacked a direct measure of road exposure, which may have affected the model performance. Data regarding several parameters, including the indication for implantation, were missing at several occasions. The researchers were unable to identify the crashes specifically caused by sudden cardiac incapacitation. DISCLOSURES: This study received a grant from the Heart and Stroke Foundation of Canada. One author reported receiving a Mentored Clinician Scientist Award from Vancouver Coastal Health Research Institute and a Health Professional-Investigator Award from Michael Smith Health Research BC. Another author reported receiving support from Michael Smith Health Research BC and the British Columbia Emergency Medicine Network.
