Could your neighbourhood impact your dementia risk? Study says yes
People living in areas surrounded by greenery may have a lower risk of dementia, according to a new study.
A new study conducted by Stockholm University and the Karolinska Institute in Sweden suggests that the proximity of green spaces to one's home may have a significant impact on the risk of developing dementia. The research, which involved nearly 3,000 participants followed for 16 years, found that residing closer to vegetation was associated with a 20% lower risk of dementia.
The strongest protective effect was observed for greenery within 100 meters of the home, with the link weakening as the distance between the residence and green zones increased. The study's lead researcher, Cecilia Stenfors, emphasized that the immediate environment surrounding a person's home plays a crucial role in promoting brain health and healthy aging.
She explained that natural environments can provide psychological restoration, reduce stress, and enhance feelings of well-being. Additionally, green spaces may indirectly protect against dementia by shielding individuals from hazardous environmental factors such as traffic noise, air pollution, and extreme heat. With the number of people living with dementia projected to surge to over 14 million by 2050 in the European Union, the authors argue that sustainable urban planning is essential.
This should include the preservation of existing vegetation and the creation of accessible and usable green environments for people of all abilities, both for public health benefits and climate adaptation purposes.
