#Heat & #ChronicIllnesses

City Mayors if you had the budget to do just ONE thing tomorrow to make your city cooler and safer during heatwaves, what would it be? 🌳 More trees? 🚌 Shaded bus stops? 🏫 Cooler schools? 🏠 Cool roofs? 🚶 Better walkability? One intervention only. I'm curious what people would prioritize. #Heat

Everyone who says "1922 had the same temps as 2024" has never looked at the actual data. So here it is. 144 years. NASA. 1922 and 1944 are orange dots. 2024 is where the line stops climbing — for now. This isn't a narrative. It's climate reality of our time. #ClimateEmergency #Heat

Barefoot on pavement in a city in Asia right now: 52°C surface temp. Barefoot on grass 10 metres away: 28°C. That gap kills people. Not slowly — in hours. And we're still debating whether to plant more trees. #heath #healthfacts

The AC on my neighbour's house is blowing hot air into the street at day and nights. 42 degrees outside. Everyone's units running. At what point does "personal cooling" become a shared public health problem? Asking for every city in Asia right now. #Heat_And_Cooling #climatechange #PublicHealth

Ebola isn't just spreading through contact. It's spreading through distrust. Empty treatment centers. Secret burials. Attacks on health workers. We've seen this before — DRC 2018. Same region. Same failure. Trust IS the infrastructure. #Ebola #DRC

The cooking oil hiding in most processed food may be quietly rewiring your gut. And most people have no idea it's there.

What’s often missed: heat kills slowly and invisibly. Older adults, dense cities, poor housing—this is where risk concentrates. And with hotter nights rising, recovery disappears. The real question: are our cities designed to keep people alive? #HeatKills

63% of all deaths in 2021 weren't from COVID. They weren't from accidents. Or infections. They were from diabetes. Heart disease. Cancer. Stroke. Diseases we mostly know how to prevent. 43 million people. One year. Same preventable causes. Why aren't we talking about this? #NCDs #PublicHealth

Nobody's talking about the real reason heart disease rates aren't dropping. It's not just what's in your food. It's what's been done to it. 🧵 Here's what a landmark European cardiology review just found about ultra-processed foods — and why it changes everything about how we think about prevention.

This isn’t a worker choice problem—it’s a system design failure. No safety nets, weak enforcement, and global demand for cheap clothes. We’ve optimized for low prices, not safe supply chains. #FastFashion #PublicHealth #Climate

Old biscuit ad: "fuel for fitness." We laughed. Same trick runs today. New buzzwords. Slicker packaging. Ultra-processed. Aggressively marketed. Quietly reshaping what kids think food is. The ad aged. The strategy didn't. What are we normalising right now? #nutrition #chronicillness

Don't panic. #Hantavirus #GlobalHealth

Your BP might be wrong—and it’s not the machine. We treat BP as objective. It’s not A JAMA Internal Medicine trial shows arm position alone can inflate readings by up to 6.5 mmHg Same person. Different posture. Different diagnosis Small measurement errors → real people labeled #hypertensive #Health

Surviving a heart attack: 50% odds in 1960. 90% today. One of medicine's greatest wins. Now explain why heart attacks in young adults are rising. #PublicHealth #CardiovescularHealth

Not every viral claim is medical truth. Ivermectin treats parasites — not viruses, cancer, or hantavirus. #hantavirus #ivermectin

Confounding problem in #UPF research is real Studies find associations — but people who eat more UPF also sleep less, earn less, move less. Did the biscuit cause the disease? Or the 60-hour work week and no access to a decent kitchen? We don't know. And the headlines didn't say that. #Nutrition

“Green fuel” is one of the thirstiest products on Earth 1L of ethanol can consume ~2,000L of water across crops + processing This isn’t just replacing fossil fuels. It’s replacing water India’s 1,800 crore L target could lock in massive water stress. We’re turning water into exhaust #WaterCrisis

New 2026 science: ocean warming has already cut "sea breeze days" in most major coastal cities. No sea breeze = more heat, more smog, more AC. The ocean was doing the work quietly. Now it can't. This isn't future risk. It's already happening.

A research team from the Chinese Academy of Sciences is testing a different route: convert coal directly into electricity using a fuel cell—no combustion. Early results suggest higher efficiency. If this scales, it doesn’t just clean coal— it challenges how we generate power. ⚡ #Energy #Climate

The heat safety rules were designed for younger bodies. Older adults hit their survival limit much sooner — and we're only just finding out. What's safe at 30 may not be safe at 70. 🌡️ #HeatSafety #ClimateHealth

Your brain doesn't just bounce back after heavy drinking. 2026 research: damage to the region controlling attention, stress & memory can persist MONTHS after quitting. Long-term? Linked to dementia. Quitting is step 1. Healing is another journey. 🧠 #chroninillness #PublicHealth #alcohol

Heat exposure raises neurodevelopmental delay risk by 35% during pregnancy and 53% after birth. 100k+ children. 551 cities. J-shaped curve. Climate change isn't just environmental. It's neurological. 🧠🔥 #climatechnage #PublicHealth

Your bread is not the same bread your grandparents ate. Globally, since the 1960s: ↓ Zinc in wheat ↓ Iron in wheat ↓ Protein in wheat ↑ Yield ↑ Profits ↑ Calories Modern wheat varieties fail basic nutrition targets. Iron levels are described as "alarming." #Nutrition #PublicHealth

Young women. No smoking history. Lung cancer Researchers looked at their diets — and found something no one expected They eat healthier than most people. More produce, more whole grains. But "clean eating" comes with a catch: the dirtiest pesticide loads are on the healthiest foods. #PublicHealth

We keep treating infections as “human” or “animal” problems. But in Uruguay, a fungus is moving through street cats into humans — exposing a system gap, not just a medical one. One Health isn’t optional anymore. It’s delayed infrastructure catching up to reality. #PublicHealth #Onehealth

We’re telling young people to “plan for the future” while also quietly suggesting the future is unstable. That contradiction is what’s breaking people. The real skill isn’t prediction. It’s adaptation under uncertainty. But grief must be acknowledged first. #ClimateAnxiety #YouthMentalHealth

Iceland has mosquitoes for the first time. That sounds small. It isn’t. It means the Arctic is no longer stable enough to keep species out. And we’re still not systematically tracking what is moving in. The danger isn’t mosquitoes. It’s everything we’re not noticing yet. #climatecrisis

We swapped sugar for “zero calorie.” But we didn’t ask what replaced it. When a sweetener turns into a compound that can damage DNA, this isn’t a diet choice—it’s a food system question. Health doesn’t come from labels. It comes from what’s actually inside.

Most cities blame parents for childhood obesity. But Kumasi banned salt shakers Manchester created 400m junk-food buffers Nairobi funds fresh school meals locally Regulation. Procurement. Community power Asian cities don’t lack ideas—they lack implementation at city level #Obesity #PublicHealth

Can your city clearly define “social sustainability”? Or is it still a buzzword doing policy work it can’t support? #sustainabiity

Lancet: 52% of the decline in air pollution deaths came from reduced vulnerability — healthcare, poverty reduction — not cleaner air. Emissions fell. More lives were saved by making people harder to kill. #CleanAir #HealthPolicy

We talk about climate change like it’s carbon and temperature. But research in Nature Health shows a deeper impact: disasters also break social ties—and loneliness rises with real health consequences. Not just homes are lost. Support systems are too.

Are “safe” sugar substitutes really safe? Mouse study found sucralose + stevia disrupted gut bacteria and inflammation—and effects showed up in offspring who never consumed them. Early evidence, but could today’s diet echo into the next generation? #publichealth

Scientists set the lethal heat threshold at wet-bulb 35°C. Older adults in Phoenix and Bangkok were dying below that. We've been using the wrong number. And undercounting the bodies. #climatecrisis #PublicHealth

If borders closed tomorrow, most countries couldn’t produce a complete diet. Food security isn’t calories. It’s nutrients, diversity, resilience. We didn’t just globalize food— we engineered dependence into survival. #FoodSecurity #PublicHealth

MIT tracked 126,000 stories on Twitter over 11 years. False news reached people 6x faster than true news. The culprit wasn't bots. It was us. We are the algorithm. Imagine the health harm it would have caused! #SciComm #PublicHealth

We didn’t have a groundwater problem. It had a measurement problem. Millions of recharge structures built. Billions spent. But we track what’s constructed—not what actually refills aquifers So “success” rises on paper… while water stress persists Infrastructure is visible. Outcomes aren’t #Water

A virus in shrimp may be quietly threatening human vision 👁️ We treat seafood risks as food poisoning—not infection surveillance. Now a shrimp virus is linked to an eye disease causing blindness. We monitor land zoonoses. The ocean? A blind spot. #PublicHealth #Surveilance

India's poorest spend 6.6% of income on tobacco — more than on medicine. 20.5M households could move up an economic class just by quitting. (BMJ Global Health, 261k households) We call this a health problem The data calls it a poverty trap Why won't development budgets treat it as both? #tobacco

A frog's gut outperformed chemo — in the lab. 🐸 One dose of a naturally occurring bacterium eliminated 100% of tumors in mice. It hunts tumor tissue, spares healthy organs. Early research. Human trials years away. But the mechanism is remarkable. #CancerResearch #Microbiome t.co/PoA1g9mVMx

Cities say “health first.” Few redesign streets to prove it. Phnom Penh did. Car-free. Smoke-free. 100,000 people reclaiming space every weekend. This isn’t urban design. It’s tobacco control + active mobility + dignity in one street. If this works here—what’s stopping your city? #PublicHealth

Hot weather doesn't just exhaust you. It makes you more likely to die by suicide. A global meta-analysis found suicide rates climb with every degree of heat — especially in men. Women? Higher anxiety. Higher self-harm. Who's funding mental health in a hotter world? #ClimateCrisis #MentalHealth
