A recent study suggests that just 22 minutes of physical activity a day can reduce the increased risk of premature death associated with a sedentary lifestyle for people over 50.
People in developed countries spend an average of nine to ten hours a day sitting. Whether we're at the computer, stuck in traffic, or relaxing in front of the television, our lives are becoming increasingly sedentary.
This is concerning because prolonged periods of sitting are linked to various health issues, including obesity, heart disease, and certain types of cancer. These health problems can contribute to earlier mortality.
However, new research shows that for people over 50, as little as 22 minutes of daily physical activity can lower the elevated risk of premature death resulting from a highly sedentary lifestyle.
Here's what the researchers did:
The research team analyzed data from two studies conducted in Norway, one in Sweden, and one in the United States. These studies involved approximately 12,000 people aged 50 and older who wore wearable devices to track their daily activity levels and sedentary behavior.
The participants were observed for at least two years (with a median follow-up period of 5.2 years) during the study period, which spanned from 2003 to 2020.
The analysis took into account several lifestyle and health factors, such as education, alcohol consumption, smoking, as well as a history of heart disease, cancer, and diabetes. All this data was linked to national death registries.
