About B10
B10 is an initiative by Alexander, physiotherapist and clinical epidemiologist. There is a huge amount of health information out there, little of it reliable and even less usable.
B10 separates the wheat from the chaff and translates trustworthy research into concrete choices you can make today.
No dogma, no supplements we happen to be selling. Just research, nuance and common sense.

Sleep: the underrated cornerstone of your health
We spend a third of our lives asleep, and yet most people barely know what happens during those hours — or why it so strongly shapes how you feel, think, move and recover during the day.

B10 for your studio, practice or team?
Do you teach, run a yoga studio, a practice, or a company with staff who’d benefit from solid health knowledge? Alexander gives lectures on location on sleep and on other topics tailored to your audience.
Were you at a lecture?
Everyone who attends a B10 lecture gets the promised deep-dive. For the sleep lecture that’s:
• a summary of the evening on a single page;
• a sleep checklist with the changes that really matter;
• a reference list of the studies the lecture is based on, so you can read on yourself.

What to expect from a B10 lecture
No slide deck full of jargon, and no wagging finger. A B10 lecture is built around real questions: why does my body work the way it does, and what does that mean for me? Alexander explains complex things in plain language, shows where the evidence is strong and where it’s shaky, and leaves plenty of space to think along. You go home with insight that sticks — and a short handout to read it back.
Depth behind the lectures, in plain language and with sources included.

Sleep
Why sleep matters: what happens in your body overnight
Sleep feels like doing nothing. In reality it’s one of the most active and best-organised processes in your entire body. While you sleep, your brain clears out waste, locks.

Sleep
The sleep cycle explained: light, deep and dream
Sleep isn’t one state but a journey through different stages, repeating four to six times a night in cycles of about ninety minutes. Broadly, there are two kinds of sleep.

Sleep hygiene that actually works (and the myths you can let go)
Sleep hygiene” sounds dull, but it simply means the habits and conditions that make good sleep possible. Not everything you read online is true. Here’s what the evidence shows.
Measurement Know Your Number
You can’t improve what you don’t measure. The B10 measurement gives you an honest picture of where you stand right now no guessing, just a clear starting point to build on. One morning, a few careful measurements, and you’ll know exactly what deserves your attention.
