How Just 22 Minutes of Daily Exercise Can Enhance Your Health

In today's fast-paced world, people in developed countries spend an average of nine to ten hours a day sitting. Whether it's in front of a computer, stuck in traffic, or unwinding in front of the TV, our lives have become increasingly sedentary. However, this sedentary lifestyle is a cause for concern, as prolonged periods of sitting are linked to a multitude of health issues, including obesity, heart disease, and certain types of cancers. These health issues, in turn, can contribute to an earlier death. But there's hope on the horizon, as a recent study suggests that even a mere 22 minutes of exercise a day can significantly lower the increased risk of premature death associated with a highly sedentary lifestyle.

Uncovering the Research

The groundbreaking study, which could change the way we view our daily routines, combined data from two studies conducted in Norway, one in Sweden, and one in the United States. These studies encompassed a total of about 12,000 participants aged 50 or older, who wore wearable devices to track their activity and sedentary behavior during daily life. Over a span of 2003-2020, the participants were closely monitored for a minimum of two years, with a median follow-up period of 5.2 years.

In-depth analyses took into account various lifestyle and health factors, such as education, alcohol consumption, smoking status, and previous history of heart disease, cancer, and diabetes. This wealth of data was meticulously linked to national death registries, providing a comprehensive overview of the participants' health and activity levels.

The 22-Minute Threshold

The results were eye-opening. Among the 805 participants who sadly passed away during the follow-up period, it was observed that those who were sedentary for more than 12 hours a day faced the highest risk of death, a staggering 38% higher than those who were sedentary for only eight hours a day. However, here's where the study takes a remarkable turn – this heightened risk was only evident in individuals who engaged in less than 22 minutes of moderate to vigorous physical activity daily. For those who exceeded this 22-minute threshold, the risk of premature death became strikingly similar to those who were sedentary for just eight hours a day.

Furthermore, the study revealed a consistent trend: the more time spent engaged in physical activity, the lower the risk of death, irrespective of the total time spent being sedentary. For instance, for individuals who were sedentary for less than 10.5 hours a day, an additional ten minutes of moderate to vigorous physical activity daily could reduce the risk of mortality by up to 15%. Even for those classified as highly sedentary (logging 10.5 hours a day or more), an extra ten minutes of daily activity lowered their mortality risk by an impressive 35%.

Addressing Limitations

While the findings are promising, it's essential to acknowledge the study's limitations. The research couldn't examine how changes in physical activity or sedentary time over the course of several months or years might impact the risk of death. Additionally, the study focused solely on participants aged 50 and above, making it less directly applicable to younger age groups. Furthermore, cultural and lifestyle differences between the countries in which the studies were conducted might have influenced data measurement and analysis.

A Positive Outlook

Despite these limitations, the study's results align with a growing body of evidence that explores the complex relationship between physical activity, sedentary time, and mortality. The findings emphasize the positive impact of even brief bouts of exercise. The 22 minutes of daily activity does not necessarily need to be a continuous session; it can encompass various forms of physical activity integrated into one's daily routine, such as taking the stairs, going for a brisk walk during lunch, or even performing short at-home workouts.

Several studies employing wearable devices have also highlighted the benefits of short bursts of high-intensity activities like stair climbing or energetic outdoor home maintenance tasks like lawn mowing or window cleaning. Such activities have been found to lower the risks of mortality, heart disease, and cancer. Moreover, recent research indicates that moderate to vigorous bouts of activity lasting only three to five minutes provide similar benefits in reducing stroke and heart attack risk as longer bouts exceeding ten minutes. In essence, these findings suggest that being active, even if only on the weekend, offers similar health benefits as being active throughout the entire week.

Furthermore, the advantages of physical activity and the reduction of sedentary time extend beyond physical health. Research has demonstrated that these lifestyle changes also positively impact cognitive health.

In a world where sedentary routines, such as desk jobs, can often foster a lifestyle that is hard to change, incorporating short bursts of activity into our daily lives can make a substantial difference in improving our health and extending our longevity. Whether it's a brief walk during a break, choosing the stairs over the elevator, or dedicating a few minutes to an at-home workout, this study serves as a reminder that every minute of physical activity counts towards a healthier, longer life.


In conclusion, the study underscores the significance of daily physical activity in mitigating the health risks associated with prolonged sitting. With a mere 22 minutes of exercise each day, individuals can significantly reduce their risk of premature death, especially when that activity is of moderate to vigorous intensity. This revelation provides a glimmer of hope for individuals trapped in sedentary lifestyles and reinforces the notion that every moment of physical activity contributes to a healthier and longer life.
