Ways to Stay Active at Work and Home - Avoid Inactivity Risks to Health
Inactivity is an insidious, silent and lurking killer, perhaps similar to the risks of smoking or obesity.
► The World Health Organisation lists the humble ‘physical inactivity’ as the fourth largest killer of adults in the world.
► It is responsible for about 10% of premature deaths in the Western world.
► A sedentary lifestyle, worsened by being inactive sitting behind a desk or working on a computer for 8-10 hours a day increases the risk of depression, obesity, diabetes, stroke, heart attack and for developing a number of chronic diseases.
► It also diminished the quality of life as the inactive are likely to be more depressed and less likely to be engaged in activities beyond work, or gazing at a computer screen, or watching a video or TV monitor.
Recent research has shown that remaining inactive and sitting down continuously without a break, even for several hours a day is harmful. This applies even for people who get regular exercise when not working.
Researchers who monitored more than 50,000 middle-aged women for a total period of six years concluded that for every session of two hours watching television increased their rate of becoming obese by about 20% and of developing diabetes by about 15%.
Health Risks of Inactivity at Work
The health risk of prolonged sitting time itself, needs to be separated from the overall amount of activity on a daily basis. considered separately to the lack of physical activity outside work hours.
For example, a person may go for a 30 minute jog or run after work every day, but may spend 4 or 5 hours sitting at a desk at work during the day and another 4 hours in front of a computer screen or TV every night. Does this really matter?
Several long term research studies have shown that adults who spend less time throughout the day, sitting for more than 2 hours at a time, have a lower risk of death, from cardiovascular disease, obesity and other ailments.
The study also showed that the amount of time spent sitting was not correlated to the amount of general activity.
► That is, the ‘couch potatoes’ were evenly spread amongst those that exercised regularly at other time, and those that were inactive all the time.
► The amount of time spent sitting was positively correlated with increased rates of mortality for both men and women.
► The correlation was stronger for women than men.
► Men who spent more than 6 hours sitting down had an 18% higher risk of mortality than those who only spent 2 hours or less sitting down.
► For women the increase in mortality rates was about 37%.
► This applied whether or not the people were generally active at other times.

Another Australian Study showed similar results with a correlation between hours spent sitting and increased risk of mortality.
The study used mortality data and questionnaire information for 220,000 individual Australian.
► The correlation between sitting duration and all-cause mortality was consistent for both men and women, age groups, body mass index.
► Prolonged sitting was found to be a mortality risk factor that was independent of the amount of physical activity undertaken.
► This confirmed the findings of the previous study. The results are summarized below.
How to Sit Down for Shorter Periods of Time
The research data provides clear evidence that sitting down for more than about an hour at a time is detrimental for your health. So what can you do about it.
The answer is to identify the time when you sit down and break them into shorter periods of 30 minutes or so with various activities. This is a very simple concept. Examine when are the periods during the day you spend sitting down. The example below provides and example with the long sirring down periods highlighted:
- Brisk walk 30 minutes
- Drive to work in the car 60 minutes (Sitting)
- Work on computer for 4 hours (Sitting)
- Eat Lunch for 45 minutes (Sitting)
- Work on the computer 4 hours in the afternoon (Sitting)
- Drive home 60 minutes (Sitting)
- Training in the gym or running 30 minutes
- Eat Dinner 30 minutes (Sitting)
- Watch TV, a Video or work on the computer for 4 hours (Sitting)
It is clear that action is needed at home, at work and while traveling to work. Driving a car is probably not as bad as sitting at a desk, and there is probably not a lot your can do about sitting down while driving.
However the other long period of sitting down can all be broken down into shorter periods by adding various breaks deliberately or by adopting various tactics to generate these breaks.

10 Tips for being Active at Work and Avoiding Sirring Down too long
- Stand up and routinely take a break from your computer every 30 minutes. There are many fabulous books and articles than outline various exercise routines you can use in the office.
- Take breaks during long meetings. They will be more productive that way
- Stand up to greet a visitor to your workspace and walk to a meeting room
- Always use the stairs, not the lift
- Stand up to take phone calls. You will find it is less distracting and helps you focus better
- Walk to a colleagues desk and discuss things in person with people rather than phoning or emailing.
- Drink more water. This works two ways as you will need to go to thekitchen or watercooler more often, and have more toilet breaks, which shortens your sitting time. Drinking more water is also good for your health.
- Use a height-adjustable desk and try working standing up rather than sitting down.
- Use a ball as a chair and use under-desk exercise equipment and chairs designed for exercising.
- Encourage you work mates to take regular breaks as well and devise various way of exercising together such as one of the many 60 second workouts.
