Reminder to go touch grass

A scientist in Japan demonstrated that the air inside a forest strengthens your immune system for a full month

The study is incredibly fascinating:

Qing Li, an immunologist at Nippon Medical School in Tokyo, took 12 men on a 3-day forest trip. These were slow walks with no breathing exercises and no set route.

Then he tested their blood and found a surge in natural killer cells -- the immune cells your body uses to fight cancer and virus-infected cells.

Remarkably, the effect didn't fade when they went home, it was still measurable 30 days later.

A control group that walked the same distance through a city showed no change at all.

Pine, cedar, and cypress trees release compounds called phytoncides to defend themselves from insects and bacteria. You breathe them in, and Li believes they switch your immune cells into high gear.

He estimates one forest walk a month may be enough to keep those cells elevated all year.

The best medicine might not even need a prescription -- just a walk among the trees.

1000 credits I paid for and don't have. Can someone actually look at this?

Ticket raised with the transaction proof attached. Response so far:

"Sorry I couldn't help answer your question... I'll let my team know so I can do better next time!"

That's it. No escalation, no human, nothing since.

There are people who genetically need only 4-6 hours of sleep per night.

Researchers describe them as energetic, upbeat, resilient, and hard to keep still. Many appear to have type A personalities.

This trait has been associated with rare mutations in five genes: DEC2, ADRB1, NPSR1, GRM1, and SIK3.

Now consider this.

We spend about a third of our lives asleep. Take an 80-year life at 8 hours per night. That’s roughly 27 years spent sleeping. Now imagine a drug that cuts the requirement to 4 hours instead of 8, safely, without sacrificing health, mood, or lifespan.

From age 20 to 80, you would buy back a decade of waking life.

Knowing that Eli Lilly purchased Centessa Pharmaceuticals for $6.3B and its orexin drug pipeline, I think Lilly may be betting on something much broader than narcolepsy.

I believe they're betting on democratizing short sleep.

We have the closest thing to a human existence proof, and it’s not crazy to think we’ll eventually have an “Ozempic for sleep.”

Few medical devices have changed diabetes care as profoundly as the glucometer.

Device: Roche Accu-Chek Instant S

What other medical device quietly transformed healthcare without receiving enough attention?

Everyone should build a bullshit radar in life. It’s the most useful skill with the highest return today. So many experts in everything that the head feels like junkyard. A good bullshit radar is like a vaccine to stop you from becoming stupid.

Dear friends, if you were unable to read the review/interview of my book and work with The Indian Express, here is it is!
Please take a moment out of your time and read this beautifully written reflection on my book, The Liver Doctor: Stories of Love, Loss and Regeneration.

The big advance in the science of human aging is the ability to quantify it and relate the metrics to health and disease. A new paper today @CellCellPress takes this to the next level with organ clocks and multiple biologic layers (omics) of data across the lifespan.

Friends, stop drinking alcohol.

Not cut back. Eliminate.

> alcohol increases cortisol
> disrupts REM sleep
> accelerates epigenetic aging
> shrinks hippocampal volume
> elevates resting heart rate
> raises inflammatory markers
> impairs glucose metabolism for 16 hrs

One drink does that.

Can anyone show me another Prime Minister who publicly claims that promoting Homeopathy within the healthcare system can help their nation progress?

Just one?

In the country of its origin, Germany, the Health Minister Karl Lauterbach is actively moving to abolish state-funded insurance coverage for homeopathic treatments, arguing that services without proven medical benefits should not be financed by statutory health insurance.

People like this man are giving me second hand embarrassment because his team of science illiterates is the sole reason why India is now the pseudoscience capital of the world, dethroning China to the second place.

Government of India releases details on the GLP -1 Drugs' use, risks, and regulation.

Key Takeaways:
GLP-1 (Glucagon-Like Peptide-1 agonist) drugs are prescription medications used to treat type 2 diabetes and obesity but carry serious side effects and must only be taken under the supervision of a qualified medical specialist.

In India, GLP-1 drugs can only be prescribed by endocrinologists, internal medicine specialists, and cardiologists they cannot be purchased over the counter.

Drug Controller General of India, in collaboration with State Drug Controllers, has intensified regulatory surveillance, conducting inspections and warning that non-compliance will result in licence cancellation, fines, and legal action.
