As we sit at the computer our shoulders are usually forward and we are hunched over for extended periods of time. Our bodies are not designed to sit all day. Sitting for long periods of time has a negative effect on health. It can cause pain and tightness in the back and neck, tingling in the extremities and poor posture. Along with this, there are also increases in the risk of heart disease, Type II Diabetes and some cancers.
Immediately after sitting down, muscle metabolism (maintenance and function processes) slows down and less calories are burned. After a prolonged period of this lifestyle LDL cholesterol (bad cholesterol) increases and weight gain occurs.
After just two weeks, muscles begin to atrophy (shrink and weaken) and oxygen consumption (use) decreases, making it more difficult to climb stairs and walk the longer distances.
It has also been shown that in women bone mass can drop by 1% after a year of sitting for 6 hours a day.
Reduce these effects of long term sitting; take breaks; switch things up:
- Stand every 45 minutes to 1 hour (set an alarm or timer)
- Maintain periods of moderate activity during the day.
