People who sit in a sitting position for more than 3 hours a day have a 2-fold increased risk of developing deep vein thrombosis in the lower limbs, and sitting for more than 12 hours in a row increases the risk of pulmonary embolism.
04. Sitting for a long time hurts the nerves: dizziness,

Australian researchers found that sitting and watching TV for more than four hours a day was associated with an 80 per cent increased risk of death from cardiovascular and cerebrovascular disease and a 46 per cent increase in the risk of death from other causes compared to those who watched TV for less than two hours.
