We have all heard people say that they are old souls trapped in a young body, however, this is a figure of speech people use. While this phrase may mean you like old school things, it can also happen literally. Sometimes your body ages faster than you do, but this is the biological age we are talking about. While chronological aging is counted as the years we have lived, biological age can be faster or slower. Think of it as perishable food. If you leave them in unfavorable environments, they can spoil fast, becoming edible. However, when you keep them in the correct environment with even temperature, the food will stay edible for longer than it should. Our bodies are similar in that sense. If you take care of it, limiting processed food, exercising and taking care of your health, you will find that your biological age is much slower or healthier than a person who does the opposite. However, what is the connection between biological aging and our lifestyle. How do we age slower/faster depending on our choices. A new study suggests that signs of faster aging in your body are connected to a higher chance of developing dementia and stroke. Specifically, researchers found that people with shorter telomeres in their white blood cells tend to have an increased risk of these two brain conditions. These findings were published recently in the journal Neurology. What Are Telomeres and Why Do They Matter? Think of telomeres as the protective caps on the ends of your chromosomes, much like the plastic tips on shoelaces. They prevent your chromosomes from unraveling and getting damaged. Every time your cells divide, these telomeres get a little shorter. This makes them a useful way to estimate a person's biological age, which is how much wear and tear your body has accumulated from stress over time, rather than just your age in years. Your biological age can be quite different from your actual age. Lifestyle Habits Can Counter the Risk However, there's good news: the study found that this link between shorter telomeres and brain diseases wasn't present in people who maintained healthy lifestyle habits. This suggests that even if your body shows signs of faster aging, you can still reduce your risk of age-related brain diseases. This includes things like keeping a healthy weight, limiting alcohol, getting enough sleep, and exercising regularly. These healthy choices can help delay the aging of your cells and lower your chances of developing these conditions, especially if you're already at a higher risk. Shorter Telomeres, Higher Risk For this study, researchers looked at genetic data from over 356,000 people. They categorized participants into three groups based on the length of their telomeres: short, medium, or long. They then compared telomere length to people's lifestyle habits and whether they had developed dementia, stroke, or depression. Over an average of seven years, nearly 26,000 people developed at least one of these three age-related brain diseases. People with the shortest telomeres had significantly more cases of these brain diseases compared to those with the longest telomeres. Overall, after considering other risk factors, individuals with short telomeres were 11% more likely to develop one of these brain diseases. More specifically, they faced an 8% increased risk of stroke, a 19% increased risk of dementia, and a 14% increased risk of late-life dementia.It's important to remember that this study shows a connection, not a direct cause-and-effect relationship between telomere length and brain health.
