Public Health Wales has worked in collaboration with members of the Financial Wellbeing Delivery Plan for Wales Steering Group, including the Money and Pensions Service and Welsh Government, to set out the links between money and health outcomes in Wales. Financial wellbeing is a key building block of people’s health and wellbeing because when people have money worries it can lead to chronic stress, which is harmful to our physical and mental health. Here we highlight who is most affected by these issues and how a public health approach can improve long-term health and financial wellbeing.
