This definition matters. Without the ability to make informed decisions, self-care becomes guesswork, shaped by trends, habits, and fragmented advice rather than understanding. In this context, even the most well-intentioned behaviours lack direction and are difficult to sustain.

Beyond lifestyle behaviours such as nutrition, movement and sleep, self-care also involves the ability to recognise and manage minor, self-limiting conditions with confidence. This includes navigating over-the-counter (OTC) medicine options, understanding when self-treatment is appropriate, and knowing when to seek professional advice.

In practice, this is where self-care becomes real. It is reflected in everyday decisions: how we interpret symptoms, the actions we take first, and how we respond when those actions are not enough. These are not trivial choices; they are the foundation of how individuals interact with the healthcare system.

Health literacy underpins this. To care for ourselves effectively, we must be able to access, understand and apply health information in a way that is relevant to our own lives. Health literacy is not simply about knowledge; it is about decision-making capability.

The consequences of this gap are already visible. Despite 9 in 10 UK adults reporting confidence in using OTC medicines, 75% of GP consultations for self-treatable conditions still result in advice to use OTC treatments¹. Confidence, it seems, is not the issue. Applied understanding is.

Most of us will recognise the experience: a quick search for a minor symptom returns hundreds of answers, often conflicting, and rarely tailored to our own context. What begins as reassurance can quickly become overwhelming. In that space, uncertainty grows, and it becomes easier to default to the perceived safety of a GP appointment rather than acting with confidence.
