How Lack of Free Time Could Increase Dementia Risk
Have you ever found yourself struggling to find some spare time in your busy schedule? A recent study suggests that a shortage of free time, also known as ‘temporal inequity’, could be a contributing factor to an increased risk of dementia.
Researchers at the University of New South Wales (UNSW) in Australia have published a new perspective article highlighting the importance of prioritizing time for the sake of our brain health. They argue that having available time is crucial for maintaining overall health, including getting enough sleep, eating nutritious food, and engaging in social activities.
Various lifestyle factors such as loneliness, poor diet, lack of exercise, and inadequate sleep have been linked to an increased risk of developing dementia. According to epidemiologist Susanne Röhr, up to 45 percent of dementia cases worldwide could be prevented by addressing these modifiable risk factors. However, many individuals struggle to find the time to prioritize activities that promote brain health.

The researchers emphasize that time poverty, or a lack of discretionary time, poses a significant barrier to reducing dementia risk. Balancing work, caregiving responsibilities, and other daily obligations often leaves individuals with limited time to make healthy choices.
Notably, certain demographics, such as women and individuals with lower incomes, face additional challenges in managing their time effectively. Women are typically responsible for the majority of caregiving tasks, while those with lower incomes may have longer working hours or irregular schedules.
According to the researchers, dedicating approximately 10 hours a day to brain care is essential for maintaining cognitive health. This includes adequate sleep, proper nutrition, social interactions, and physical exercise. However, for many individuals, especially those in disadvantaged or caregiving roles, meeting these recommendations is unrealistic under current circumstances.
Addressing time poverty requires a comprehensive approach that involves community support and policy changes. Suggestions include improving childcare services, implementing flexible work arrangements like four-day work weeks, enhancing public transportation networks, and advocating for the right to disconnect from work.
If proactive measures are not taken, the researchers warn that dementia rates will continue to rise, particularly impacting the most vulnerable populations. Neuropsychiatrist Perminder Sachdev emphasizes the need to address temporal inequity as a critical component of brain health policy and research.
The study has been published in The Lancet Healthy Longevity, underscoring the importance of recognizing and addressing the impact of time constraints on dementia risk.
