This week it’s all about the ocean and health and we have three incredible guests joining us.

We’re talking mental health with Jason Fox - former UK Special Forces Marine Commando and now TV presenter and mental health campaigner. Bhakti Sharma from Rajasthan in India has swum in all five oceans and eight seas and holds the world record for the longest swim in Antarctic waters - she tells us about the inspirational power of open water swimming and finally we dive into the science with Dr Jo Garrett to explore why being by the sea - and in fact all blue spaces - is good for health and well being.
