Waresley, Cambridgeshire: In a near-freezing lake, I’m treated to an up-close view of one of my favourite birds The spring-fed lake is a picture of tranquillity this morning. On the far side, ivy-clad trees touch trunks with their watery counterparts, creating an image of a child’s mirror painting folded along the shoreline.

Only the soft blurring of branches distinguishes reflection from reality. The scene might look serene, but I must focus on my breathing to stay calm as I lower myself slowly into the water, which has chilled to a wintry 6C.

I started cold water swimming last month, hoping it would help relieve the chronic pain caused by adenomyosis . It’s only my fourth session, and I’m wondering if I have the confidence to swim across the lake when a quick movement on the water catches my attention.
