Why health literacy underpins effective, consistent self-care
In an age where we are surrounded by constant advice on how to optimise our health, from influencers to clinical sources, and with 6 in 10 UK adults using online platforms to look up symptoms of self-treatable conditions1, self-care has never been more prominent, nor more difficult to navigate. The challenge is no longer access to information, but knowing what to trust, how to apply it, and when to act.
Self-care is often reduced to a set of behaviours in the media: eat well, move more, manage stress, sleep better. While important, this framing risks turning self-care into a checklist rather than recognising it as a capability.
Effective self-care must be broader than recognising the need to look after our bodies; fundamentally, it requires understanding them. This means knowing what is normal for us, recognising early changes, and interpreting how our bodies respond to lifestyle, stress, environment and illness. That understanding creates the autonomy and ownership needed to make appropriate decisions and take action.
At its core, self-care is making, and acting upon, informed choices for our health.
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.
For self-care to work in practice, people need access to health information that is not only credible, but usable. This includes everyday support provided by pharmacists, alongside trusted sources such as the NHS and organisations like the Self-Care Forum.
Information must be accessible at the point of decision, enabling individuals to act with confidence, rather than defaulting to uncertainty.
Self-care is not just what we do for our health; it is how well we understand the choices available to us, how confidently we act on them, and how consistently we apply them over time. If we want self-care to be effective, health literacy must be treated as a foundational component, not an optional extra.
Self-care is not a checklist. It is a capability, and one that will increasingly define how individuals engage with their health, and with the healthcare system.
