The risks of sitting for too long in front of a computer

We tend to expel less energy while we are sitting down than if we were to move around or stand. Studies have found that numerous negative health effects are linked to sitting down for long periods of time.From obesity, raised blood pressure, high blood sugar, extra body fat around the waist and high cholesterol levels that make up metabolic syndrome, prolonged periods of sitting increase risk of death from cardiovascular disease and cancer.

Spending a lot of time sitting at a desk, behind your steering wheel, or in front of the TV can be harmful. A report of 13 studies of sitting time and activity levels found that people who sat for over 8 hours a day without physical activity had a risk of dying remarkably close to the risks caused by obesity and smoking. This analysis of data from more than a million people found that an hour and a quarter of medium intense physical activity each day counteracted the negative of too much sitting. A different study found that a longer amount of sitting time contributed only a little to mortality for people who were most active.

Further study is required on the effects of sedentary and physical activity on health. But it looks clear that less time sitting and more time moving about would certainly contribute to healthier lives. Anyone can begin by simply standing rather than sitting whenever you can or finding ways to walk around at your work place.

Take a break from sitting every 30 minutes.

Tips for improving your well-being include standing whilst you talk on the phone or watching television. If you work at a desk, switch to a standing desk or find a high table or work top. Walk alongside your colleagues for meetings instead of sitting in a conference room.

Attach your desk above a treadmill with a computer screen and keyboard on a stand or a specially built vertical desk. This allows you to be in motion throughout the day. 

The impact of movement, even light movement, can be beneficial. You will use more calories, which can lead to weight loss and boost in energy. Not only that, physical activity helps keep up muscle tone, your ability to move and your mental well-being, especially in later years.

Around the world, especially in the United States, people aren’t as active as previous generations. Research estimates that we are not physically active (sedentary) for about 7.7 hours a day (an average). On top of this, fewer than 20% of us are employed in jobs that require physical activity with more and more people spending over 50% of the working day seated. This buildup of time spent sitting can cause serious health issues even for people who aren’t usually active . 

The dangers of too much sitting.

Our bodies are meant to be up and moving, whether you’re working or playing and to be seated only when resting. A sloth-like lifestyle, which may include sitting in an office for long periods of the day, getting around by sitting in a car or bus, spending time watching Television or browsing the Internet while sitting can affect our bodies in numerous ways. Examples of this can be:

  • Burning less calories, which can cause weight gain.
  • Lose muscle strength and have weaker bones.
  • Have reduced blood circulation.
  • Have a weakened immune system.
  • Obesity.
  • Osteoporosis.
  • Stroke.
  • Develop inflammation.
  • Develop hormonal imbalances.

Health problems related to too much sitting

Health issues associated with a seated lifestyle and not getting regular exercise can raise your risk of:

  • Early death.
  • Type 2 diabetes, Heart disease, and a few types of cancer.
  • Metabolic syndrome (raised blood pressure, higher blood sugar, more body fat around the waist, and abnormal cholesterol or triglyceride levels).

If you sit for long periods of time in an office working on a computer, you open yourself to be at risk for getting physical strain and overuse injuries.

Moving throughout the day can be even more beneficial than exercise to lower your risk of all these health problems.

Scientists first noticed something during a study that between two similar groups:  guards or conductors, who are standing and transit drivers, who sit for long periods. Though their diets and lifestyles were very similar, those that sat doubled their risk of heart disease compared to those that did not.

If you sit for too long, your brain could resemble that of a person with dementia.

It could be that you’re often alone and looking at your screen. This can disrupt your sleep, and you can get more anxious. This also might lead to social anxiety since spending a lot of time alone can make you withdraw from loved ones. Scientists are still trying to uncover an exact cause.

3. Set up your desk properly and maintain a good posture

The computer screen should ideally be about an arm’s length away from you and the top of your monitor should be at forehead level. This will help  avoid looking up or down.
The mouse and keyboard should be at a height that keeps your elbows at your side and bent at 90 degrees. This will keep you from having to stretch too far to use them.
Whilst seated, your hips and knees should be at 90-degree angles. Have your feet flat on the floor or use a foot rest.
Your head should remain directly over your shoulders. Don’t lean forward closer to your computer.
