Is Sitting The New Smoking? Understanding The Health Hazards of Sedentary Lifestyle

In recent years, you might have come across the phrase, “sitting is the new smoking.” This rather alarming statement has gained significant attention in the health and wellness world, likening the health risks of prolonged sitting to those of smoking. It’s a bold claim, but is it just a sensational headline, or does it hold weight? Today, we’ll delve into the research behind this provocative statement and the implications of a sedentary lifestyle on our overall health.

Understanding Sedentary Behavior:

Sedentary behavior refers to activities that require minimal body movement and result in low energy expenditure. These include sitting, lying down, watching television, and other forms of screen-based entertainment. With the advent of technology, many people spend considerable portions of their day engaging in sedentary behavior, whether it be at work, during the commute, or at home.

The Health Implications of a Sedentary Lifestyle:

Just like smoking, sedentary behavior has been linked to a number of chronic diseases. Prolonged periods of sitting can lead to obesity, type 2 diabetes, certain types of cancer, heart disease, and even premature death. A study in the American Journal of Epidemiology found that individuals who sat for more than six hours per day had a significantly higher risk of mortality than those who sat for less than three hours per day.

Moreover, prolonged sitting is associated with increased risk of mental health issues, such as anxiety and depression. This has been largely attributed to the reduced physical activity and limited social interaction that often accompany sedentary lifestyles.

Can Exercise Offset the Effects of Sitting?

While regular physical activity does provide numerous health benefits, it may not completely offset the risks of a sedentary lifestyle. A study published in the Annals of Internal Medicine found that even among those who exercise regularly, those who sat for long periods had a higher risk of health problems than those who did not. This suggests that it’s not just about getting regular exercise, but also about breaking up long periods of sitting.

Sitting Less: Practical Tips for Change:

Given the serious health implications of a sedentary lifestyle, it’s crucial to make a concerted effort to sit less and move more. Here are some practical tips:

  1. Stand Up Regularly: Make it a habit to stand up every 30 minutes. You could stand up when you’re on the phone, or walk around during a break.
  2. Use a Standing Desk: If feasible, consider using a standing desk at work. This allows you to alternate between sitting and standing throughout the day.
  3. Walk More: Try to incorporate more walking into your daily routine. This could involve parking further away from your destination, taking the stairs instead of the elevator, or going for a short walk during lunch.
  4. Stretch and Move: Perform stretching exercises or light physical activity, such as yoga or Pilates, during your breaks.


While the phrase “sitting is the new smoking” might seem sensationalist, it underscores a significant health concern in our increasingly sedentary society. Much like smoking, sitting for prolonged periods is a modifiable risk factor for many chronic diseases. Although sitting might not be entirely avoidable in our modern world, by becoming aware and taking proactive steps to reduce our sedentary time, we can steer clear of the ‘new smoking’ and embrace a healthier lifestyle.
