Is climate change increasing the levels of toxic arsenic in our rice?
When it comes to food, most Indians cannot imagine a day without rice. Lunch is rice, and rice is lunch – and rice is also sometimes breakfast or dinner or just part of a number of other food items we consume. But how healthy is the rice we are eating?
Scientists have known for a while now that a lot of rice contains some amount of arsenic. A new study that was published in The Lancet Planetary Health last month, however, had some newer, more worrying findings: it found that with rising carbon emissions and rising temperatures, the arsenic levels in rice will rise. The study was conducted over a 10-year period on 28 different strains of paddy rice at four different locations in China. Arsenic is a known carcinogen – it is linked to cancers including lung and bladder cancer as well as to other serious health conditions.
So what does this study mean for India, which is a large rice-growing and rice-eating country and one that is also experiencing climate change effects? What does arsenic do to your body in the long term? Are there methods to grow rice that decrease the amount of arsenic in it? What can you do to make the rice you are eating at home safer?

The silent surge: Early onset of chronic illnesses
Across India's sprawling office complexes, sleek co-working hubs, and hybrid home workspaces, a health crisis is silently unfolding. While much attention is focused on digital disruption, AI transformation, and skilling for the future, an equally urgent, less recognised, and under-discussed crisis is taking root: the early onset of chronic illnesses among working Indians, often a decade earlier than seen Employee Health Report 2025, by Plum, analysed data from over 100,000 telehealth consultations, 25,000 insurance claims, 1,998 health camp participants, and 512 survey responses across 6,000+ companies. The report reveals a stark reality: chronic health conditions such as diabetes, hypertension, cardiovascular diseases, and mental health disorders are now manifesting by the age of 35 or even earlier in India's salaried class. For a nation staking its future on its demographic dividend, this is both an economic and social red flag. What it signifies is a decade of lost health. In most developed countries, lifestyle-related chronic conditions tend to show up post-age -50, giving people a full three decades of stable employment productivity before grappling with health setbacks. But in India, the average age of onset has slid into the thirties, even the late twenties. What is alarming is the intensity and clustering of these diseases: comorbidities are becoming the norm rather than the mental health at report highlights that nearly 20% of urban white-collar workers in India suffer from multiple chronic ailments. Worse still, mental health issues are surging, with 1 in 5 employees having sought professional help, and 1 in 5 considering quitting due to burnout. This is just the data captured from insured employees, an urban upper crust. The figures among gig workers, contractual staff, and MSME employees – most without insurance or workplace wellness programmes – would be factors are driving this premature health decline: First, ironically, is the nature of work itself. India's service economy, powered by IT, finance, education, media, and e-commerce, leans heavily on sedentary desk jobs. With the rise of remote work, digital presence has replaced physical exertion. Employees routinely clock 10-12-hour days, eyes glued to screens, meals skipped or hastily eaten, and movement limited to keystrokes and Zoom a growing urban disconnect from wellness. In metropolitan areas, access to green spaces, safe pedestrian infrastructure, or time for leisure activity is shrinking. Long commutes, overcrowding, and pollution aggravate physical inactivity and highly processed, delivery-based food makes a recipe for metabolic is the phenomenon of cultural stigma and denial. In workplaces, chronic fatigue, burnout, or depression are often dismissed as a 'phase', a lack of willpower, or even laziness. This stigma drives employees to delay seeking care. Until they mental health problems are growing. What is unfolding is not just a physical health crisis, but a psychological one. Burnout is no longer a buzzword; it is a lived reality. Employees report symptoms ranging from insomnia and anxiety to persistent demotivation and even clinical depression. Managers are often unable to identify or act upon these red flags, partly due to a lack of training and outdated assumptions about 'professionalism.' This is made worse by the demand for longer work hours. Unlike physical illnesses that have defined markers and treatment paths, mental health disorders are murkier and harder to quantify – making them both widespread and dangerously economic costs of this invisible but growing health challenge are inescapable. Chronic illnesses are not just private tragedies – they are societal economic liabilities. A workforce beset by hypertension or stress is less productive, more prone to absenteeism, and more likely to switch jobs frequently. For companies, this translates into spiralling health insurance claims, lost person-hours, and increasing employee turnover. At a macro level, the early onset of chronic diseases shortens productive work lives, potentially flattening India's much-touted demographic dividend. For a country hoping to leverage its young population to power global growth engines, this is akin to trying to sprint on a sprained in is a need for a new paradigm of workplace health. We can no longer afford to treat employee health as a side benefit or a corporate box-ticking exercise. We need a fundamental shift in how workplaces think about health – from reactive treatment to initiative-taking well-being. What might such a shift look like?.Institutionalising preventive health checks: Annual health screenings, biometric risk assessments, and lifestyle counselling should become default offerings. These should be mandated and subsidised, particularly in sectors like IT, finance, and movement into the workday: Standing desks, stretch breaks, walking meetings, and ergonomic workplace design can go a long way in reducing the toll of sedentary lifestyles. Urban planners and architects too must rethink the live-work-commute health first aid: Companies must not only offer access to mental health professionals but actively normalise the use of these services. Mental health sick days, manager sensitisation workshops, and peer support groups must be and policy: Just as CSR mandates funding social causes, a small percentage of profits could be directed to health and wellness infrastructure, including access to gym memberships, therapy, and is time to address the rapid epidemiological transition from communicable diseases to non-communicable diseases in both urban and rural India. The early onset of chronic diseases must receive dedicated attention through awareness and surveillance mechanisms. Employers, policymakers, and healthcare providers must collaborate to foster a culture that prioritises health and data is clear. The trend is urgent. The impact is generational. Investing in employee health is not just an economic necessity but a moral imperative. Our greatest asset – human capital – must not become our greatest vulnerability..(The writer is the Director of School of Social Sciences, Ramaiah University of Applied Sciences)

How sleep tech is transforming rest and wellness across India
Technology has revolutionised nearly every facet of modern life — from ergonomic seating that supports posture during long office hours to customised skincare targeting specific skin concerns. Amongst these lifestyle upgrades, one area gaining remarkable momentum is sleep — a pillar of health that remains underappreciated yet a country like India, where stress levels are soaring and sleep deprivation is becoming a silent epidemic, tech-driven solutions could be the answer to better rest and long-term wellness. India Today spoke with Mr Ganesh Sonawane, Co-founder and CEO at Frido, to understand how this rapidly evolving domain is reshaping the way Indians TECH: A PARADIGM SHIFT IN REST AND RECOVERYSleep tech refers to the ecosystem of gadgets and innovations designed to enhance sleep quality using intelligent systems. Gone are the days of just a comfy mattress or a white noise machine. Today's sleep technology employs AI, smart sensors, and machine learning to monitor, analyse, and improve sleep. 'Sleep tech is not about comfort alone any more. "It's about measurable health outcomes,' said Mr Sonawane. 'From heart rate to snoring patterns, technology is now helping decode sleep on a much deeper level.'SMART PILLOWS: FROM HEADRESTS TO HEALTH MONITORSOnce a basic bedroom accessory, the pillow has turned into a smart sleep companion. Smart pillows now offer adjustable firmness, ergonomic shaping, and integrated biometric sensors. These innovations cater to various sleep positions and spinal health, while also tracking movement, snoring, and even REM of these pillows also feature temperature-regulating technology, maintaining optimal coolness or warmth depending on user preference. Some AI-enabled models also detect snoring and subtly reposition the user's head to alleviate obstruction, offering relief for both the sleeper and their and mattresses are also undergoing a high-tech transformation. Today's smart beds incorporate pressure-sensitive support systems that adapt in real-time to your body. Some even allow couples to customise each side of the mattress based on their individual comfort needs."One big barrier in India is price," said Mr Sonawane. "We noticed that people continue using old mattresses, unaware of the long-term harm they cause. That's where solutions like mattress toppers — a simple, tech-enabled upgrade — are gaining traction.'These toppers offer temperature regulation and orthopaedic support without the need to purchase a new mattress — a game-changer in price-sensitive markets like TECH AND ITS DIRECT IMPACT ON HEALTHThe importance of sleep extends far beyond rest. Sleep tech devices actively combat insomnia, sleep apnea, and chronic fatigue. By using biofeedback and real-time analysis, they promote better sleep hygiene and mental backs this up. Studies show that employees who nap or sleep better experience higher productivity and income gains. Additionally, managing sleep apnea — a condition that affects a growing number of Indians — can drastically reduce risks of hypertension and Type 2 underestimate how much poor sleep contributes to poor immunity, obesity, and even mood disorders. Sleep tech is a proactive way to reverse that,' Mr Sonawane LIES AHEAD: THE FUTURE OF SLEEP TECH IN INDIAThe next frontier for sleep tech lies in personalised AI-powered sleep plans. Innovations will soon allow for smart lighting, tailored soundscapes, and neurofeedback-based interventions that stimulate deeper, restorative sleep is also catching up fast. As digital awareness increases and more urban dwellers prioritise wellness, the adoption of sleep tech is expected to surge.'Technology is evolving to not only track your sleep but guide you toward healthier rest patterns,' said Mr Sonawane. 'From smart pillows that detect breathing irregularities to cooling mattresses that adjust to summer nights, the future is about sleeping smarter — no longer.'In an age of information overload and endless hustle, sleep has emerged as a silent casualty. But thanks to technological innovation, it is also becoming the gateway to better health, productivity, and India begins to recognise the long-term value of sleep, the integration of smart sleep solutions into everyday life will only grow. And as Mr Sonawane concluded: 'Investing in how we sleep is investing in how we live.' advertisement

What do you need to know about the Covid-19 spike in India?
What do you need to know about the Covid-19 spike in India? Yet again, we are talking about a virus we would much rather forget – Covid-19 is in the news with over 4,300 cases and over deaths as of June 4. New sub-variants, descendent from the Omicron lineage first reported at the end of 2021, are believed to be driving the spike in cases. So far however, a majority of the cases have been mild, with very few requiring hospitalisation, according to the government. Is Covid-19 here to stay? Do we have any reason to be concerned about the new variants? Do we need vaccines or booster shots again? And, what as individuals, can we do to stay safe? Guest: V.
