Research from the University of New South Wales (UNSW) highlights that a lack of free time, termed “temporal inequity,” may significantly elevate the risk of developing dementia. This finding emphasizes the importance of prioritizing personal time for mental health and overall well-being.
The study suggests that inadequate available time affects crucial health-related activities. Individuals often struggle to maintain healthy habits such as getting sufficient sleep, purchasing nutritious food, and engaging in regular social interactions. These lifestyle factors are increasingly recognized as vital in reducing the likelihood of dementia.
Susanne Röhr, an epidemiologist involved in the research, notes that “up to 45 percent of dementia cases worldwide could be prevented if modifiable risk factors were eliminated.” However, she points out that many people lack the discretionary time necessary to exercise, rest, eat healthily, or maintain social connections. This phenomenon, referred to as “time poverty,” serves as a hidden barrier to dementia risk reduction.
The pressures of modern life—such as extensive work hours, childcare responsibilities, and caregiving for elderly parents—often leave individuals little time to make healthier choices. The researchers emphasize that certain demographics face even greater time constraints. For instance, women are typically responsible for the majority of caregiving tasks globally, while individuals with lower incomes often work longer or less predictable hours.
To mitigate dementia risk, the study recommends that individuals dedicate around 10 hours a day to brain care. This includes adequate sleep, balanced nutrition, social interactions, and regular physical activity. As Simone Reppermund, a psychology researcher, states, “for many, especially those in disadvantaged or caregiving roles, this simply isn’t achievable under current conditions.”
Addressing “time poverty” is crucial for effective dementia prevention. The researchers propose a multifaceted approach that includes enhancing community support systems, improving childcare options, implementing more flexible working arrangements—such as four-day work weeks—and establishing better public transport networks. These solutions aim to empower individuals to allocate time for their health and well-being effectively.
Despite the challenges, the researchers underscore the necessity of taking steps to combat the rising rates of dementia. If no action is taken, it is predicted that the burden will disproportionately affect the most disadvantaged segments of the population.
Perminder Sachdev, a neuropsychiatrist, adds that “brain health policy and research have focused heavily on individual behavior change.” He stresses the importance of providing individuals with the temporal resources needed to act on health recommendations. Just as governments address income inequality, it is essential to also tackle the issue of temporal inequity.
The findings of this research have been published in The Lancet Healthy Longevity, raising awareness about the critical intersection of time management and public health.
