For those people who have consigned their swimming togs to the back of the drawer until next summer, it might be time to think again. While sea swimming has grown hugely in popularity in recent years, and especially during lockdown, a new book provides even more reasons to keep it going even as temperatures drop.

In Winter Swimming: The Nordic Way to a Healthier and Happier Life, Dr Susanna Søberg explores the science behind the claims that taking a dip in cold water is one of the best things you can do for your health. The book delves into the ‘cold shock’ effect and says that those who take the plunge will feel a range of benefits, from the surge in feelgood hormones to the relief of pain.
