What if summer once meant danger instead of vacations? What if a simple dip in a swimming pool could change a child’s life forever? 

In this episode, Dr. Ravi Kumar takes you back to the terrifying era of polio in mid-20th century America, a time when hospitals filled with iron lungs, cities closed public spaces, and parents lived in constant fear. You will uncover how a mysterious virus crippled a generation, and how a global race for a vaccine transformed medicine and changed the fate of the world. 

Travel from the panic-filled summers of the 1950s to the scientific breakthroughs that led to one of the most successful vaccines in human history, and learn how the courage of scientists, volunteers, and families helped bring polio to the brink of eradication. 

In this episode, you will discover: 

• Why polio became more dangerous after sanitation improved 

• How the virus attacks the nervous system and causes paralysis 

• What iron lungs actually did and why they became symbols of the epidemic 

• The story of Paul Alexander, who lived 72 years inside an iron lung 

• How Franklin D. Roosevelt launched the March of Dimes and fueled vaccine research 

• Jonas Salk’s bold bet on a killed-virus vaccine that defied scientific dogma 

• The massive 1954 field trial involving 1.8 million Polio Pioneers 

• The Cutter incident and how it reshaped vaccine safety 

• Albert Sabin’s oral vaccine and the United States and Soviet partnership that surprised the world 

• How global vaccination campaigns drove polio cases down 99 percent 

• Why polio eradication is closer than ever, but not guaranteed 

Key Takeaways 

• Polio was once the most feared disease in America, paralyzing thousands of children every year 

• Iron lungs provided negative-pressure ventilation for children who could no longer breathe 

• Jonas Salk’s inactivated polio vaccine and Albert Sabin’s oral vaccine worked together to end widespread transmission 

• The March of Dimes was one of the earliest national crowdfunding movements for medical research 

• Polio remains endemic in only two countries, which shows that eradication is possible but requires vigilance 

• When diseases become invisible, public memory fades, and motivation to vaccinate can fall 

Why This Story Matters Today 

Polio shows how fear, science, innovation, cooperation, and public courage can shape human destiny. It reminds us that vaccines did not just prevent illness, they reshaped modern life. The lessons of polio continue to guide how we face outbreaks, medical uncertainty, and public skepticism today.

 What if one scientist could stop famine, save a billion lives, and change the fate of nations? 

In this episode of Tribulations, Dr. Ravi Kumar tells the astonishing true story of Norman Borlaug, the quiet American farm boy whose breakthroughs in wheat genetics transformed the global food supply and rescued India and Pakistan from the brink of collapse. 

You’ll travel from the dusty fields of Iowa to the war-torn farmlands of the Indian subcontinent, tracing how Borlaug’s relentless science sparked the Green Revolution, fed the hungry, and won him the Nobel Peace Prize. Dr. Kumar also explores the powerful moral lesson behind Borlaug’s legacy, that feeding the world is not just an act of science, but an act of peace. 

In this episode, you’ll discover: 

• How two consecutive monsoon failures pushed India and Pakistan to the edge of famine. 

• The breakthrough that made Borlaug’s wheat disease-resistant, drought-tolerant, and photoperiod-insensitive. 

• How Borlaug and M. S. Swaminathan brought the Green Revolution to India amid war and political chaos. 

• Why Borlaug’s “shuttle breeding” and dwarf wheat varieties changed global agriculture forever. 

• The moral link between food security, peace, and humanitarian aid — and why it still matters today. 

Key Takeaways 

• Norman Borlaug’s innovations turned starvation into self-sufficiency across India, Pakistan, and Mexico. 

• The Green Revolution showed that science can be humanity’s greatest peacekeeping tool. 

• By increasing yields, Borlaug’s work saved millions of acres of forests from deforestation. 

• Foreign aid and agricultural investment once made up over 4% of the U.S. budget, today's budget has been eliminated. 

• History proves that generosity and global cooperation create stability where isolation breeds chaos.

 Heartburn is not too much acid, it's acid in the wrong place. 

This episode explains GERD, why PPIs create dependence, and how to fix reflux by restoring physiology, not suppressing it. 

In this episode, you will discover: 

• Why GERD is a mechanical problem, not an acid problem 

• How the lower esophageal sphincter and diaphragm form your anti-reflux barrier 

• The rebound loop created by chronic acid suppression and hypergastrinemia 

• The foods, habits, and medications most likely to trigger reflux events 

• A practical two to four week reset to reduce pressure, improve timing, and clear acid faster 

• A stepwise taper from PPIs to H2 blockers, including what to expect during rebound 

• Simple tools that help in the transition, including baking soda and fennel seed 

• When to keep acid suppression and when to talk to your doctor first 

Who this episode is for: 

• Daily or near-daily heartburn, persistent reflux on medication, or difficulty coming off PPIs 

• Listeners who want a physiology-first plan that restores normal digestion 

Key takeaway: 

Fix the barrier and the timing, not the acid. When physiology is restored, reflux recedes and digestion improves. 

Safety first: 

Seek care urgently for trouble swallowing, unintentional weight loss, vomiting blood, black stools, chest pain that could be cardiac, or symptoms that do not improve with a responsible trial.

What happens when a life-saving cure is discovered, and then given away for a single dollar?

In this Tribulations episode, Dr. Ravi Kumar tells the remarkable story of Frederick Banting, the farm boy turned surgeon whose late-night idea led to the discovery of a method for extracting insulin and saved millions of lives. You’ll travel from the starvation wards of the early 1900s to the sweltering attic lab in Toronto where Banting and Charles Best performed the experiments that changed medicine forever. Dr. Kumar also explores the moral and policy issues that continue to shape insulin access today.

In this episode, you’ll discover:
 • How diabetes went from a fatal disease to a manageable condition.
 • The late-night inspiration that drove Banting to isolate insulin.
 • The brutal experiments and the first successful treatment in a dying child.
 • Why Banting sold the patent for one dollar, and what that decision means today.
 • How insulin’s legacy has been both a triumph of compassion and a failure of modern medicine.

Key Takeaways
 • Before insulin, type 1 diabetes was a death sentence; starvation diets only delayed the inevitable.
 • Banting’s insight to tie off the pancreatic ducts allowed insulin to be isolated intact.
 • His team’s discovery turned childhood diabetes from a fatal disease into a chronic, livable one.
 • Banting gave away the patent to keep insulin affordable, but modern pricing has drifted far from his vision.
 • The story of insulin reminds us that compassion, not commerce, should guide medical innovation.

Sleep isn’t a luxury; it’s the foundation of every system in your body. 

In this episode of The Dr Kumar Discovery Podcast, Dr. Ravi Kumar explores the neuroscience, hormones, and daily habits that drive great sleep. You’ll learn how to optimize circadian rhythm, manage sleep pressure, and use proven evidence-based strategies to restore energy, focus, and long-term health. 

In this episode, you’ll discover: 

• What really happens in your brain during deep and REM sleep 

• How your circadian rhythm and adenosine work together to trigger rest 

• Why poor sleep drives insulin resistance, inflammation, and hormone imbalances 

• The neuroscience behind light, temperature, and consistency as sleep levers 

• How to use magnesium, glycine, L-theanine, and tryptophan safely for better sleep 

• When melatonin helps (and when it doesn’t) 

• Why CBT-I outperforms sleeping pills for chronic insomnia 

• What to know about sleep apnea, the silent disruptor of deep sleep 

Key takeaway: 

Sleep is not wasted time; it is the nightly maintenance that keeps your brain, metabolism, and mood running at peak capacity. When sleep works, everything else works better. 

Whether you’re struggling with insomnia, jet lag, or simply want to wake up sharper, this episode gives you a clear, science-based playbook to take control of your nights and your days.

When to Screen for Sleep Apnea  

If you snore loudly, wake up gasping, or experience daytime fatigue, you may have sleep apnea. Take the STOP-BANG questionnaire here: http://www.stopbang.ca/osa/screening.php  

If your score is high, talk to your doctor about a formal sleep study. Treating sleep apnea can dramatically improve energy, blood pressure, and long-term health.

What if one of the greatest medical breakthroughs of the past century wasn’t a high-tech device or a billion-dollar drug, but a humble mix of salt, sugar, and water? 

In this Tribulations episode, Dr. Ravi Kumar tells the story of how oral rehydration solution (ORS) emerged from the chaos of cholera epidemics and became one of the simplest and most lifesaving discoveries in medical history. 

You’ll hear how scientists and doctors across continents, from Robert Crane’s biochemical insight to Dilip Mahalanabis’s daring field implementation, turned a molecular mechanism into a global movement that has saved tens of millions of lives. 

This isn’t just history, it’s something you can use. Dr. Kumar also explains how to prepare oral rehydration solution yourself, when to use it, and how it could one day save you or your loved ones in an emergency. 

In this episode, you’ll discover: 

• How Dr. Robert Crane’s discovery of the sodium-glucose co-transporter opened the door to oral rehydration therapy.
• How Dr. David Nalin and Dr. Richard Cash developed the first oral formula that dramatically reduced deaths during cholera outbreaks.
• How Dr. Dilip Mahalanabis risked everything to implement the therapy during the 1971 refugee crisis, and dropped mortality rates from 30% to 1%.
• The crucial role of BRAC and community education in spreading lifesaving knowledge across rural Bangladesh.
• Why oral rehydration solution remains one of the most effective treatments for dehydration from cholera to travel sickness.
• The exact WHO/UNICEF formula and how you can make it yourself at home with common ingredients.
• A personal story of how oral rehydration solution saved Dr. Kumar and his son on a mountain in the Colorado Rockies.

Dr. Kumar’s Take
The story of oral rehydration therapy is one of science meeting humanity. It’s a reminder that medicine doesn’t always need to be high-tech to be revolutionary.

This discovery shows how courage, collaboration, and compassion can save lives on a massive scale and how something so simple can still hold power in your own hands today.

Practical Application

• Keep WHO/UNICEF-type ORS packets in your travel bag, camping kit, or first aid box.
• If you don’t have packets, mix 1 liter of clean water, ½ teaspoon of salt, and 6 level teaspoons of sugar.
• For infants and children, rehydrate with small sips frequently.
• Avoid sports drinks for serious dehydration — they have too little sodium and too much sugar.

Key Takeaways

• ORS is one of the simplest and most lifesaving therapies in modern medicine.
• It’s effective for dehydration caused by diarrhea, vomiting, heat exposure, or altitude sickness.
• Its development required both molecular insight and heroic fieldwork under desperate conditions.
• Teaching communities to make and use ORS remains one of the greatest triumphs in public health.

 Acetaminophen, better known as Tylenol, has long been considered the safest choice for pain and fever during pregnancy. But a new review from researchers at Mount Sinai and Harvard raised concerns: could prenatal acetaminophen use be linked to higher rates of autism and ADHD in children? 

The debate exploded when President Trump publicly warned pregnant women to “fight like hell” against taking acetaminophen. His statement left doctors, parents, and the public asking: what does the science really say? 

In this episode of The Dr. Kumar Discovery Podcast, Dr. Ravi Kumar breaks down the evidence behind the headlines. You’ll learn what the recent systematic review actually found, how to separate association from causation, and why the largest sibling studies may contradict the supposed risks. 

In this episode, you’ll discover: 

• The history of acetaminophen, from coal tar to Tylenol.
• Why acetaminophen became the go-to pain and fever reliever in pregnancy.
• The difference between relative and absolute risk, and what the numbers really mean.
• How cord blood and meconium studies suggested higher risks — but with major caveats.
• Why large sibling studies from Sweden and Norway showed no increased risk at all.
• The role of animal studies and biological plausibility in shaping the debate.
• Why regulators like the WHO still recommend acetaminophen as the safest option.
• A practical framework for making decisions during pregnancy without fear or politics.

If you or someone you love is pregnant, and you’ve been worried by the headlines, this episode will help you cut through the noise. You’ll walk away with a clear, balanced view of the evidence so you can make informed choices with confidence.

***Correction*** - The CNCM I-745 strain of Saccharomyces boulardii is currently only sold by Florastar. This is the most studied strain of Saccharomyces boulardii. I've also tried brands such as Jarrow and Pure, and they've worked well, but the majority of the research supports the CNCM I-745 strain. In the podcast, I mentioned that most of the strains are this CNCM I-745 strain, but that was factually incorrect.  

What if a simple yeast, scraped from the peel of tropical fruit during a cholera epidemic, could change the way we protect our microbiome? 

In the 1920s, French microbiologist Henri Boulard stumbled upon a probiotic unlike any other. Saccharomyces boulardii isn’t a bacteria, but a hardy yeast that survives heat, stomach acid, and bile. Today, it’s one of the best-studied tools for preventing antibiotic-associated diarrhea, treating traveler’s diarrhea, and protecting gut health when illness strikes. 

In this episode of Tribulations, Dr. Ravi Kumar takes you on a journey that weaves history, science, and practical medicine. You’ll discover: 

• The remarkable story of how Boulard’s curiosity led him from alcohol fermentation to a lifesaving probiotic during a cholera outbreak.
• Why Saccharomyces boulardii acts as a “shepherd” in the gut, preserving balance while pushing back against harmful bacteria.
• Clinical trial evidence showing its effectiveness against antibiotic-associated diarrhea, traveler’s diarrhea, and recurrent C. difficile infection.
• Practical dosing strategies for adults and children—when to use it, how long to continue, and important safety caveats.
• Why a $15 supplement sometimes outperforms prescriptions in protecting your microbiome.

It’s a story of serendipity, science, and a forgotten yeast that still holds lessons for modern medicine.
