Mental Health Awareness Week runs from 10th-16th May in 2021, and its theme is ‘Nature’.
The Mental Health Foundation who host Mental Health Awareness week define nature as any environment in which we can use our senses to experience the natural world. This could include the countryside, a park or garden, coast, lakes and rivers, wilderness, plants or wildlife closer to home. It could also include nature that you can see or interact with in or from your home.
The 2 main goals are:
1) To inspire more people to connect with nature in new ways and to notice the impact of this on their mental health
2) To convince decision makers that access to nature is a mental health and social justice issue as well as an environmental one.
Research done by the Mental Health Foundation on the mental health impacts of the pandemic in the UK showed that going for walks outside was the top coping strategy for those taking part in the research and 45% reported being in green spaces as vital to our mental health.
