Many people spend long hours sitting in front of a computer before coming home and sit for hours watching television. The accumulated hours of sitting can increase the risk of developing cardiovascular diseases and diabetes. If you do not sit in a proper position in your chair, prolonged sitting also affects your posture. Your hamstrings can tighten, pulling your pelvis forward.
Researchers from the University of Queensland studying diabetes, obesity and lifestyle estimated the impact of watching television on mortality. The article "Time to watch television and a reduced life expectancy: a table of life analysis", published in the British magazine of sports medicine, detailed its conclusions. They determined that compared to people who do not watch television, for every hour you watch television after 25 years of age, you can expect a reduction of 21, 8 minutes of your life. If you watch six hours of television daily, you will live 4, 8 years less than a person who does not watch television. The root of the problem is a sedentary lifestyle. According to the study, even regular exercise does not counteract the negative effects of sitting for prolonged periods of time in front of a television set.
Sitting too high can increase the risk for diabetes and cardiovascular disease, according to research done by the Leicester diabetes center at the University of Leicester. In the study by E. G. Wilmot entitled "Sedentary time in adults and the association with diabetes, cardiovascular disease and death", published in Diabetología in 2012, the researchers analyzed data from 18 studies, following 794,000 individuals. Average adults spent 50 to 70 percent of their time sitting, which includes watching television and working. The study revealed that individuals who spend most of their time sitting up increased their risk of diabetes by 112 percent and their risk of cardiovascular disease by 147 percent.
Women vs. men
A study led by Alpa Patel at the American Society for Cancer found that women are more affected by sitting around during leisure time than men. From 1993 to 2006, Patel's team followed more than 123,000 people with no history of heart attack, stroke, cancer or emphysema. They evaluated the amount of time participants spent sitting and doing physical activities with respect to mortality. The risk of mortality was 37 percent higher for women who sat more than six hours a day out of work against women who spent three hours or less sitting.Under the same circumstances, the mortality risk for men was only 18 percent higher for those who spent more than six hours sitting daily outside of work. When sitting for a long time is combined with a lack of exercise, the mortality risk for men and women increased significantly. The increase in mortality risk caused by a sedentary lifestyle was 94 percent for women and 48 percent for men.
To counteract the effects of sitting, you need to move more. Start by doing more standing than sitting. One solution is to work stopped, which can be facilitated by a high desk. If you are more ambitious, position your desk on a treadmill and walk slowly while you work. Even the movement without haste can have a significant impact on your health. You will burn more calories and enjoy an energy boost. If you can not change the position of your desk and therefore you must be sitting while you work, get up every 20 minutes and walk around the office. Activating your muscles to stop or walk, you stimulate the body process with the breakdown of sugars and fats.
