Aims: We aim to describe the Goldilocks Day - the day where the mix of activity (sleep, sedentary time and physical activity) is "just right" for optimal overall health. Scientific Rationale: We will use analytical models to determine the best durations of sleep, sedentary time, light physical activity and moderate-to-vigorous physical activity) for a comprehensive range of health and wellbeing outcomes (e.g., blood pressure, body fat, depression, cognition). The optimal mix of activities is likely to differ across health and wellbeing outcomes, meaning that changing time use to improve one outcome may inadvertently worsen other outcomes. To arrive at a Goldilocks Day for overall health and wellbeing, there will need to be compromises. We will find the best compromises according to hierarchies that indicate how people prioritize of health/wellbeing outcomes. Project duration: 3 years Public health impact: The findings will provide evidence to support public health guidelines for recommended daily durations of physical activity, sleep and sedentary time. The findings will be implemented in an online intervention tool that enables the customization of recommendations for activity durations based on an individual's health priorities (e.g., optimized for mental health above physical health), and constraints (the user could choose to keep sleep duration constant and modify waking activities only).1 Publication
