Does Your Face Mist Actually Work? - Daily Dose 007

Dr Vincent — Wed, 22 Apr 2026 00:46:41 GMT

Face mists are everywhere right now. But most of them are just water and fragrance in a fancy bottle. Today on Daily Dose a scientist breaks down what's actually happening when you spritz something on your skin, what ingredients make a face mist genuinely functional, and why bioavailability is the question the skincare industry hopes you never ask.

Plus, the American Academy of Neurology just told patients to start bringing their smartwatch data to doctor's appointments, and we get into the actual science of venting. Turns out complaining can be good for you, BUT only if you're doing it right. Bottling things up is just as bad as the science says it is.

Walk More, Live Longer - Daily Dose 006

Dr Vincent — Tue, 21 Apr 2026 01:34:18 GMT

A study of 72,000 people just confirmed what deep down we all know: walking more saves lives. Up to 39% lower risk of dying, regardless of how much time you spend sitting.

Today’s on Daily Dose we break that down and talk about why the simplest habits keep winning in the science. We also get into why the type of olive oil in your kitchen is actively changing your brain health through your gut — and why the refining process strips out the exact compounds that make it work.

And we look at new research showing that the timing of your exercise, matched to your natural body clock, can meaningfully improve blood pressure, sleep, and metabolic health.

Three stories, all pointing to the same truth: your biology rewards you for working with it, not against it.

The Health Halo — Daily Dose 005

Dr Vincent — Mon, 20 Apr 2026 00:41:49 GMT

The food industry has spent decades perfecting the art of making unhealthy food look healthy. One buzzword on the front of a packet: organic, plant-based, gluten-free — and your brain automatically assumes the whole product is good for you.

Scientists call it the Health Halo Effect, and it's one of the most powerful marketing tools ever invented. Today on Daily Dose I break down exactly how it works, the specific words to watch out for, and how to read a food label the way a scientist does. Plus a major new study on loneliness and memory that has a surprising twist, and the collagen conversation the supplement industry doesn't want you having, because it turns out collagen alone isn't enough, and the science now shows exactly why.

Your Nose Knows — Daily Dose 004

Dr Vincent — Thu, 16 Apr 2026 01:09:00 GMT

Losing your sense of smell might sound like a minor inconvenience. Turns out it could be one of the earliest warning signs of Alzheimer's, years before any memory problems show up. Scientists this week found that the brain starts destroying smell-related nerve fibres long before symptoms appear, which changes how we think about early detection entirely.

Today, on Daily Dose I break down what that means and what to watch for, plus the science finally has an exact answer on how many serves of fruit and vegetables you actually need each day and most of us are eating half that amount. And we take a look at the Silicon Valley longevity machine and why the tech billionaires spending millions to live forever might be missing what the science has been saying all along.

Red Light Therapy: Hype vs Science - Daily Dose 003

Dr Vincent — Wed, 15 Apr 2026 00:07:02 GMT

Red light therapy is having a moment. Face masks, panels, helmets, wands — you can spend $50 or $5000, and TikTok will tell you it fixes everything from wrinkles to period cramps to longevity.

But here's the thing, the underlying biology is actually real. It works at the mitochondrial level, it has genuine clinical evidence in specific areas, and some of the results are genuinely interesting. The problem is the gap between what the science shows in a lab and what a home device actually delivers is enormous.

Today, on Daily Dose I cut through the noise on red light therapy and tell you exactly where it works and where it doesn't. Plus, a new study found that seven days of meditation produces the same brain patterns as psychedelics, and a Weizmann Institute study that flips everything we thought we knew about genes and how long we live.

The Hidden Brain Drain - Daily Dose 002

Dr Vincent — Tue, 14 Apr 2026 01:09:11 GMT

Your brain has its own cleaning system — and most of us are unknowingly shutting it down every night. Scientists have just discovered a hidden waste-removal pathway deep inside the brain, a slow lymphatic-like drain that flushes out toxic buildup while you sleep. When it stops working, that waste accumulates, and researchers believe this is directly linked to the development of Alzheimer's and other neurodegenerative diseases.

In today’s Daily Dose, I break down what this discovery actually means, why sleep is the single most underrated tool in your brain health arsenal, and how chronic inflammation could be quietly clogging your brain's drain before symptoms ever appear. Plus — the two eating habits a major new study says are linked to lower weight with no dieting, and why your gut bacteria might just replace the colonoscopy forever.

The Weight Loss Pill Everyone's Talking About - Daily Dose 001

Dr Vincent — Mon, 13 Apr 2026 00:27:19 GMT

The FDA just approved Foundayo (the first once-daily oral GLP-1 pill for weight loss), and the internet is going wild. But before you throw away your injection pen, there's a conversation we need to have about bioavailability. As a food scientist who has spent his career studying how the body absorbs and utilises nutrients, I can tell you that what you take and what your body actually uses are two very different things.

In today’s Daily Dose, I break down the science of first-pass metabolism, what it means for oral GLP-1s, and why asking "how much actually gets in?" is the most important question nobody in the wellness industry wants you asking.

Plus, the cheapest dementia prevention habit science has ever found, and a new AI tool that could warn you about disease outbreaks in your neighbourhood before you even feel sick.
