 blood circulation

One of the major disadvantage of sitting on chair for long hours is that it affects the blood circulation of our body, mainly the circulation of the pelvic area and the lower limb area get affected. Weight of sitting affects the hip area and the surrounding organs due to pressure of sitting for long hours. Improper blood circulation is not at all good as it can further result in many other major problems. While doing our work we get so much involved that we forget about the results of this. Some of us may think that it would hardly matter if we sit for long hours on chair for a day or two, or even twice a week, but the fact is that it really matters. Our body is very sensitive and when we sit on chair for long hours in one particular position the blood circulation of the lower area gets affected as the lower body do not receive sufficient amount of blood. Generally our body do not show the symptoms at an early stage , but it definitely shows the affects of long hours of sitting at one point of time, and the symptoms are disastrous. Thus it is advisable that we should do simple exercises so that the blood circulation of body is maintained and thus each and every part would receive sufficient amount of blood for its proper functioning with efficiency.


 bad posture

These days people go mad for the sake of reducing the fat of their body and maintaining a good figure but they hardly know the fact that while they are sitting for long hours , all the extra fat of their body gets accumulated around the waist area. It is really very important to get rid of this extra fat as it can further lead to high bloop pressure or in severe cases it may even cause heart attack. We should regularly do physical exercise and should use stairs instead of elevators, as these small small things are of immense importance.




Poor breathing is yet another main health disadvantage of long hours of sitting on chair. Oxygen is required for our survival and this oxygen is present in dissolved form in blood. The function of lungs is to purify impure blood and make it rich in oxygen. Due to improper blood circulation , efficiency of lungs also decreases and thus the rate of blood purification decreases. This in turn results in improper functioning of other organs.



neck pain

Sitting for long hours affects our muscles mainly back and neck muscles as we sit in a particular position for a long time. Tensions in the tissues of back and neck weakens the blood flow thus reducing the oxygen and nutrient intake of discs, ligaments and bones which further results in the tiredness of these areas . The best way to prevent this tiredness is that we should tilt the head forward to prevent neck injury . To prevent back pains one should sit without lumbar support or one can even do some stretching exercises.


 digestive system


Food is like fuel for the human body. It is very important that whatever we eat should get digested properly so that each and every cell of the body can receive the required nutrients. The food can reach the cells of the body only when it is ready to dissolve in the blood stream thus digestion is a very important phenomenon. Sitting in one position on a chair for long hours badly affects our digestive system and thus results in digestive problems which in severe cases may even result to dehydration. Thus it is very important that we should avoid sitting for long hours and most important is that we should drink lots of water and should do regular exercise so that our food gets digested properly.


 heart attack

Improper functioning of the heart may lead to diabetes and heart diseases. Sitting for long hours results in abnormal cholesterol levels. This further increases the risk of heart attack. In a heart attack the flow of oxygen-rich blood suddenly becomes blocked. If the flow of blood is not restored immediately, that part of heart muscle begins to die. Several studies suggest that people who spend most of their time sitting are more likely to have a major heart attack. The best way to protect ourselves against heart diseases is to take small breaks at an interval of every 15 minutes and also one should drink a cup of coffee.
