Monday, RTÉ One, 9.35pm
We are surrounded by water. The sea is a source of therapeutic treatment and re-energising for many; for others it's a place to unwind and let the cares of the world ebb away on the tide. This documentary follows eight people who regularly take to the water for various reasons, whether it's to deal with grief or loss, manage physical or mental health issues, or simply to hit the refresh button. Among them are Mark Earley, whose wife Liane died in 2017. By swimming daily in the Forty Foot, Mark deals with his grief one day at a time. We also meet Ray Murnane, who is confined to a wheelchair after a serious motorbike accident and hopes to get back into the water. Others include 75-year-old Anne Shanahan, who suffers from polio and finds freedom by swimming; the "Traught mermaids" who meet for swims under a full moon at Traught beach in Kinvara, Co Galway; and Susan Steele, who swims every day and is so convinced of the sea's benefits to the immune system that she's writing a book about it.
