A group of 14 women are due to set off to the Arctic Circle on Thursday. They will trek the arctic for 6 days, braving the elements and camping in below-freezing conditions. They are raising awareness and funds for the ‘Her Heart Matters’ campaign. 1 in 4 women die from heart disease, the same as men, yet research on heart disease in women is majorly lacking. Judith Gilsenan joins us to discuss the women’s expedition.
