We all know that our homes are important for our happiness and well-being, but recent research suggests that certain housing issues might actually speed up how fast we age.
A new study published in the Journal of Epidemiology & Community Health has found that living conditions like renting a private-sector home and exposure to pollution may be linked to quicker biological aging. This type of aging isn’t just about getting older; it’s about wear and tear on our body’s cells and tissues, which can affect our health in surprising ways.
One of the most eye-opening findings from the study is the impact of private renting on biological aging. Researchers found that people who rent from private landlords tend to age biologically almost twice as fast as those who are unemployed compared to those who are employed.
That means the stress and instability that sometimes come with renting privately can be just as bad—or even worse—for your health than being out of work.
But there is a bit of good news. The study suggests that this type of accelerated aging isn’t necessarily permanent. It can be reversed, which opens up the possibility that better housing policies could actually help improve people’s health.
This highlights just how much where and how we live can impact not just our mental well-being, but our physical health too. Things like high rent costs, the stress of possibly having to move, and poor living conditions like dampness or mold can all add up to big health impacts over time.
To understand these connections better, the researchers used a scientific method that looks at something called DNA methylation. This process involves tiny changes in how genes are expressed—basically, it’s how your body reads and reacts to your genes.
These changes can be influenced by the environment, including where you live and the conditions of your home. For this study, the researchers collected health information from 1,420 participants and analyzed blood samples to measure DNA methylation levels, which are markers of biological aging.
They also collected information from the UK Household Longitudinal Study and the British Household Panel Survey to understand people’s living situations. This included details about the type of housing, whether people received financial support for rent, and the stress levels associated with paying for housing.
They also looked at a range of other factors like diet, smoking, education level, and financial difficulties to see how these might be connected to biological aging.
The results were surprising. People living in privately rented homes showed signs of aging faster at the cellular level compared to those who owned their homes outright. In fact, the effect of private renting on biological aging was almost double that of the difference between being unemployed and employed.
It was also about 50% more impactful than the difference in aging seen between people who smoked in the past and those who never smoked.
The researchers also looked at people’s housing history and found that falling behind on rent payments or living in polluted areas could speed up biological aging. On the other hand, people living in social housing—where rent is typically lower and tenure more secure—did not show this kind of accelerated aging.
In fact, when all housing-related factors were considered, those in social housing aged at a similar rate as homeowners. This suggests that housing stability and affordability could play a big role in how quickly we age at the biological level.
While these findings are important, it’s good to remember that this study is observational. That means it shows a link between private renting and faster aging, but it doesn’t prove that one directly causes the other.
There are some limitations too, like the fact that the study didn’t have the latest information on housing quality and that the DNA samples were mostly from white European participants. Even so, the research shines a light on how stressful housing conditions can affect health, and it points to the possibility that better housing policies could make a real difference.
The researchers believe that changing policies to reduce the stress of private renting—like limiting rent increases, ending quick evictions, and improving housing quality—could help slow down biological aging in renters.
It’s a reminder that housing isn’t just about having a place to live; it’s a crucial part of our health and well-being. If policies are put in place to make renting more stable and less stressful, it could not only improve quality of life but actually help people live healthier and longer lives.
This study adds to the growing understanding that our living conditions have deep effects on our health, going beyond comfort and convenience. It also suggests that a secure and affordable home might not just make you feel better—it might actually help you stay younger, at least on the inside.
