The Impact of Sitting All Day – Part 2
In part 1, I looked at the impact of sitting on your muscles, but what happens in the rest of your body?
Leg Disorders
We are all familiar with the risk of deep vein thrombosis (DVT) if we take long flights. This is because sitting for long periods of time slows blood circulation, which causes fluid to pool in legs. This creates problems ranging from swollen ankles, varicose beings to dangerous blood clots.
Soft Bones
Osteoporosis is a disease marked by reduced bone strength leading to an increased risk of fractures, or broken bones. Bone strength has two main features: bone mass (amount of bone) and bone quality. Osteoporosis is often called a “silent disease” because it usually progresses without any symptoms until a fracture occurs or one or more vertebrae (bones in the spine) collapse. Weight-bearing activities such as walking and running stimulate hip and lower-body bones to grow thicker, denser and stronger. Medical researchers partially attribute the recent surge in cases of osteoporosis to lack of activity.

Weight Gain
As the body slows down while in a resting and seated positions, the metabolism naturally slows down. Calories are burned at a far lower rate, when you sit, you burn only about one calorie a minute!. For some people this can lead to weight gain becoming an issues. Being overweight is a known risk factor for many common chronic conditions including
- diabetes
- gallstones
- hypertension
- heart disease
- stroke

Good news for the desk bound…
We have all heard about the target of walking about 10,000 steps per day which roughly equates to walking 5 miles per day. Well many years ago when I worked long hours in IT some days, and lets be frank even some months, the possibility of me walking 10,000 steps per day was a pipe dream. I would say this was especially true in the winter when the dark skies, cold, wind and rain didn't exactly entice me to go outside even though I love walking. Researchers in Trondenheim University in Norway have discovered that in heart patients after just 12 weeks of walking 3000 steps every day, the hearts pumping function improved which in turn improved their ability to exercise. They concluded that moderate continuous exercise, such as walking 3,000 steps or 1.5 miles in 30 minutes had as much benefit on the heart as more vigorous, intensive exercising. Moderate walking decreased the strain on the heart, improved heart muscle function, improved blood vessel dilatation, helped form new blood vessels and lowered blood pressure. On average a sedentary person completes between 1,000 to 3,000 steps per day. Which is good news for the desk bound as you can now aim for 3,000 continuous steps which is much easier to achieve than 10,000!

How do your friends impact your health?
In my last blog article, I explored how your social network including your friends and family impact your motivation to be healthy. Being part of a group, or better yet, lots of groups is good for your health. The kind of groups doesn't seem to matter - it could be a family group, friendship group, religious or spiritual group, tennis or book club. What is important is that you identify with it and see it as a meaningful part of your life. Here are five good reasons why?
- It can help you live longer
- "As a rule of thumb if you belong to no groups but decide to join one, you cut the risk of dying over the next year in half" R Putman, Bowling Alone.
- An adequate social life provides health benefits on a par with quitting smoking
- The benefits of social ties are akin to those of exercise once you retire. In one study retirees belonging to two social groups had a 2% risk of death but if they lost touch with both groups it jumps to 12%.
- It can protect your heart
- Heart disease is generally lower for those who are members of a social group.
- The risk of death from heart disease diminishes if you belong to more than one social group.
- It can cut your risk of a cold
- Those belonging to a wide range of social groups e.g family friends, work, recreation or religious groups are least likely to come down with a cold. Six or more types of diverse groups cut the risk of a cold more than four times.
- It can alleviate depression
- The more social groups you belong to the less likely you are to suffer from depression.
- If you are depressed, joining a group can help you recover and cut the risk of a relapse by nearly a 1/4 if you join one group or by almost 2/3 if you join three.
- If you are a member of a religious or spiritual group you are less likely to have depressive symptoms and more likely to have feelings of well being.
- It motivates you to be healthy
