Hello, I'm Maurizio Pirie, and when I wish to hear positive news, I'm listening to the EpiPOD from the BBC World Service.

I'm Alex Ritson, and in this edition, I feel brave, crazy, and I feel, you know, excited inside. It's hell.

The Ukrainian refugee using cold water swimming to tackle depression. Also, turning an eyesore

into a sustainable fuel. On a bad day in Barbados, enough Sargassum washes up on the beach to power.

All the energy needs of the country for one month.

How a community came together to rescue a pod of Wales.

We've had really awesome response from the community.

Thousands of people have come down to help.

It was great to see that unity.

And driving rats.

Yes, rats can drive and they enjoy it.

As the Russia-Ukraine war continues, nearly 7 million Ukrainians are now living abroad,

with many refugees seeking help for

mental health issues like depression, anxiety and PTSD. Svetlana Sackno, a young mother from the city

of Odessa, was diagnosed with depression in Ireland, where she now lives with her family.

Her doctor recommended an unusual therapy,

swimming in the cold Irish sea.

I'm Svetlana and I flew from war from Ukraine to Ireland, to more safety place.
