The Common Activity That Could Raise Your Risk Of Dementia
A common activity many people engage in daily is sedentary behavior, such as sitting for extended periods. Research suggests that sitting more than 10 hours a day can have negative effects on brain health and may increase the risk of dementia. Here’s what you need to know and how you can mitigate these risks.
Sedentary Behavior: What Does it Mean?
Put simply, sedentary behavior refers to any waking activity characterized by low energy expenditure, such as sitting or lying down. When you watch TV for hours, work at a computer all day, or engage in other low-activity tasks, you are participating in sedentary behavior.
The Link Between Sitting and Dementia
What Research Says
Multiple studies have shown a connection between sedentary behavior and cognitive decline. For example, a new study found that people who sat for more than ten hours a day showed a higher risk of developing dementia compared to those who sat for less. This fact is alarming since many jobs and leisure activities involve prolonged sitting.
Evidence also suggests that extended periods of inactivity can lead to reduced blood flow to the brain. Reduced blood flow means fewer nutrients and oxygen reach the brain, which could potentially harm brain cells.
Why Sitting May Be Harmful
Doctors often point out the multiple health risks associated with prolonged sitting, which include obesity, heart disease, and type 2 diabetes. Since these conditions can negatively impact brain health, it’s possible that they play a role in the link between sitting and dementia.
Tips to Reduce Your Risk
While it’s not always feasible to completely avoid sitting, especially if your job requires it, there are ways to mitigate the risks:
- Take Regular Breaks: Every hour, stand up and stretch or take a short walk. This helps improve blood circulation.
- Engage in Physical Activity: Aim for at least 30 minutes of moderate exercise daily. Activities like brisk walking, cycling, or swimming can be beneficial.
- Practice Good Posture: When you do sit, ensure you’re sitting upright. Good posture can help with blood flow and reduce strain on your body.
- Stay Mentally Active: Engage in activities that challenge your brain, like puzzles, reading, or learning a new skill.
A Balanced Approach
For the most part, the key is balance. While you might not be able to avoid sitting entirely, being aware of the potential risks and making small changes to your daily routine can have a positive impact on your brain health.
