Healthy World

Cognitive decline in later life is not inevitable. Our research challenges assumptions about ageing by showing how memory and attention can be preserved through targeted interventions and lifestyle adjustments that support brain function and psychological health.

Non-invasive brain stimulation can enhance movement and coordination in older adults. These techniques offer promising, accessible tools for supporting autonomy and reducing physical limitations in later life.

Poor sleep is linked with increased anxiety, reduced concentration, and psychological distress, particularly in teens and young adults.

Our work explores how disrupted circadian rhythms impact thinking and mood, offering insights into how better sleep supports focus, learning, and long-term mental health.

Interoception, our sense of internal bodily states, has been shown to influence aspects of sexual function and satisfaction. Our research highlights how internal awareness and body trust shape experiences during solo and partnered sex, advancing understanding of an often-overlooked dimension of sexual health.

Parental decisions about childhood vaccines are shaped by how risks and benefits are communicated. We show that highlighting long-term outcomes and anticipated regret can make public health campaigns more effective, especially for encouraging HPV vaccination uptake.

Effective health communication is more than just delivering facts: it’s about helping people make informed choices.

At Essex, we explore how psychology can improve how health information is shared and understood. For example, we’ve found that how risks are framed, whether using percentages, frequencies, or clear language, can shape how trustworthy and persuasive messages feel.

Our work also shows that public misunderstanding around antibiotic resistance is common. People often view resistance as something their bodies develop, rather than bacteria. To address this, we’ve tested different message formats and found that using analogies and narrative-based explanations can help people better understand the issue and reduce unnecessary antibiotic use.

Our work also examines how weight-based stigma in healthcare and society impacts psychological wellbeing. Internalised stigma affects diet, activity levels, and health attitudes, highlighting the need for stigma resistance and more equitable, weight-inclusive approaches in public health and policy.
