Standing up for health - improving mental wellbeing during COVID-19 isolation by reducing sedentary behaviour.

The global COVID-19 outbreak and its management are disrupting ways of life and increasing the risk of poor mental and physical health for many. The restrictions on movement have made some forms of physical activity harder to achieve and increased the chances of more sedentary behaviour. Independent of exercise taken, sedentary behaviour can have a negative impact upon mental health, especially by lowering mood. We suggest evidence-based ways of reducing sedentary behaviour with commentary on how they may be adapted for life at home. These include: ways to use external cues, moving more frequently, maximising movement whilst waiting, reallocating time, workstation alternatives, restructuring the physical environment and recruiting help from others. At a time in which our mental and physical health needs are more critical than ever, the relationship between sedentary behaviour and low mood is of particular importance. The current situation represents a good opportunity for us all to change habits to implement a less sedentary lifestyle, for now and the future. This can start with changes we can make at home during lockdown.
