Steven Bartlett just hosted the world’s top critical care physician.
Dr. Roger Seheult revealed:
• A habit that cuts heart disease risk by 40%
• A common mistake as deadly as smoking
• A 15-minute fix to reboot your cellular energy
His 10 most shocking revelations:
1. A dying 15-year-old was saved by sunlight (not medicine)
He had leukemia. A flesh-eating fungus destroyed his lungs.
Doctors gave him 2 days to live. His dying wish: Go outside.
After 5 days of sun exposure, the infection vanished 60-70%.
He walked out alive.
2. Sunlight creates melatonin inside your cells (not just your brain)
Infrared light penetrates 8cm into your body.
It triggers mitochondria to make cellular melatonin, which protects cells.
Without it, mitochondria overheat causing diabetes, dementia, heart disease.
3. Avoiding sun is as dangerous as smoking
Swedish researchers tracked 30,000 women for 20 years.
Women who avoided sun had the same death rate as smokers.
The finding was so shocking they repeated it.
Richard Weller confirmed with 400,000 UK subjects.
4. Studies show hospital beds by windows discharge patients 4 days faster
Patients closer to windows heal faster, need less medication, report less pain.
We used to build hospitals with verandas for sun therapy.
Now we lock patients in windowless rooms.
5. Forest Bathing 2x your healing light exposure
Trees reflect infrared light back at you. (amplify it)
They also release phytoncides (healing compounds you breathe in).
Japanese CEOs tested this. Their natural killer cells jumped 50%.
Effect lasted 7 days from one walk.
6. People using saunas 4-7x weekly have 40% less cardiovascular death.
Saunas mimic fever to supercharge your immune system
When you heat your body to 38°C, interferon production jumps 10-fold.
This kills viruses naturally. Cold plunge after keeps heat in longer
7. Red light therapy actually rebuilds your mitochondria
Glenn Jeffrey at UCL proved 670nm red light penetrates skin and reactivates dying mitochondria
15 mins improved eyesight 25% and fixed glucose metabolism.
8. Your bedroom needs cave-like darkness for melatonin
Even tiny LED lights (clocks, chargers) shut down melatonin production completely.
Blue blockers help but aren't enough - light still leaks in.
"Dark days and bright nights" literally increase death rates.
9. Modern LED bulbs are poisoning your sleep.
Old incandescent bulbs gave full spectrum light (including invisible infrared that heals).
"Efficient" LEDs only emit blue.
For the first time ever, humans get blue without red. Your cells are starving.
10. COVID proved sunlight beats vitamin D supplements
High vitamin D predicted survival. But supplements didn't work.
Dr. Seheult took patients outside instead.
One went from 35L oxygen to discharge in 5 days.
Brazilian infrared jackets cut hospital stays by 33%.
Bonus: Your mitochondria lose 70% of their power as you age
This is why you feel tired.
Your cellular batteries are running at 30% capacity by age 60.
This causes every chronic disease: diabetes, dementia, heart failure.
But 15 minutes of infrared light resets them daily.
Longevity isn't about one magic bullet.
Dr. Seheult's "NEW START" framework is the blueprint:
N - Nutrition
E - Exercise
W - Water (including hydrotherapy)
S - Sunlight
T - Temperance (avoiding toxins like smoking and excess alcohol)
A - Air (fresh, clean air)
R - Rest (nightly sleep + weekly rest)
T - Trust (faith/spiritual practice)

98% of us can build an Alzheimer's-resistant brain.
You forget names. Walk into rooms confused.
If you're over 50, you panic it's dementia.
But Harvard's top Alzheimer's researcher Lisa Genova discovered
5 simple changes that protect your brain from this decline: 🧵
Meet Lisa Genova:
• Harvard-trained neuroscientist
• NY Times bestselling author
• Expert on memory and brain health
• Author of "Remember: The Science of Memory and the Art of Forgetting"
• Over a decade studying Alzheimer's
But first, understand what causes Alzheimer's:
Alzheimer's starts with amyloid beta protein forming sticky plaques in your brain.
After 15-20 years of buildup, these plaques trigger tangles, inflammation, and cell death.
Before that tipping point? Your forgetting is completely normal.
