Is your health…yours?
Well in a lot of ways, yeah!
Our health is a story about our bodies, our habits, and our choices.
But like with any good story, the more attention you pay, the more complex and interesting
the story becomes.
It turns out that the story of your health isn’t just about you.
It’s actually about a bunch of other stuff, too.
It’s the story of the social, economic, and environmental conditions that make up our lives.
It’s the story of people collaborating across continents and over the course of generations
to build a healthier world.
It’s the story of a changing climate, social justice movements, and even the Internet!
Public health experts take all of this into consideration to build a richly thought-out
world that works to improve our health -- sometimes in pretty cool and surprising ways!
Hi, I’m Vanessa Hill.
Welcome to Crash Course Public Health!
You might know me from YouTube, from my channel BrainCraft.
I like to take an experimental approach to content exploring our health and wellbeing
– like investigating why crystal healing exists, or creating a bedtime procrastination hotline.
Over the years, I’ve made documentaries about topics like designer DNA, and what algorithms
do to our attention and emotions.
Though my biggest experiment to date was a Hollywood reality show about improving your
sleep with the latest sleep techniques and technology.
The comments on this show highlighted one thing – it’s really hard to actually change
your behavior to be more healthy.
Heaps of viewers asked questions like: How do I actually stop using my phone in bed?
Or, How do I stop procrastinating my bedtime?
And I couldn’t answer them, because in all of the scientific literature there were no answers.
And this bothered me.
So in what is an extremely unlikely career segue, I went from being the executive producer
of a Hollywood reality show to a sleep researcher.
My research investigates the best behavior change techniques for improving your sleep,
and how we can better communicate with people about their health.
Which means less of me pretending to be a scientist on TV and more of me actually being
a scientist in real life.
It’s not the hottest take of all time, but I believe that everyone deserves the right
to live their healthiest possible life.
In fact, I believe that health is a human right.
And that’s the public health mission!
More specifically, public health is an approach to preventing disease, prolonging life, and
promoting health for everyone.
Public health experts do this work by looking at the big picture to address health across
entire populations.
To do this, they collaborate with experts in tons of other fields, including sociology,
statistics, politics, environmental science – and a lot more.
But we often don’t notice public health at work around us.
Because much like our own health, we’re usually better at noticing when public health
isn’t working than when it is.
But once you start to notice public health at work, it’s hard to stop noticing all
the places where it’s working.
Over the next 10 episodes, we’re going to unpack what public health is, who does public
health work, and why thinking about it is so important!
We’re also going to deep dive into health equity to address some big questions about
how things like identity and stigma interact with our health…like, why is it that Black
women’s bodies are literally aging faster than White women's bodies?
We’ll answer that question and more, and we’ll also do some traveling!
We’ll travel back to the Middle Ages when the English word “health” first bubbled
up, to a historic typhus outbreak in 19th century Silesia, to the fictional land of Vanessa-City.
We can’t wait to share this series with you!
