Hello and welcome to Health Check from the BBC.
I'm Claudia Hammond.
Now every week we take a look at the latest stories on health and well-being from around the world.
The first new vaccine for tuberculosis in a century is being trialled in seven countries and we'll be catching up on how the trials are going in Malawi.
And if you know someone who seems to be having difficulties with their mental health but is reluctant to get help,
what's the best way you can support them?
Now, I'd like you listening along to try something.
Take a moment and see whether you can detect your own heartbeat.
And try and do this without putting your hand on your chest to feel it.
Just see if you can feel it from within.
As much as I try, I can't feel my own heartbeat unless my heart is really racing,
like if I've just run up the stairs here at Broadcasting House in London.
So might it be useful to be good at detecting your own heartbeat, and if so, why?
Today we're talking about interoception.
That's the way our brain senses and interprets signals from our bodies, and these inner clues,
if you like, can give us an insight into our well-being.
Of course, this is not a new idea.
People have been talking about body-mind connections for centuries.
But what's new now is our understanding of how these pathways work and how we might use this heightened awareness.
