Although the sound of sitting in front of the TV with some snacks and drinks does sound like a dream come true, if you were to spend the majority of your day sat down it can negatively effect your health in a multitude of ways.
It can really impact your heart health with risks such as heart disease, high blood pressure and high cholesterol.
In some rare cases it can cause deep vein thrombosis (DVT) which is a clot that can form in your leg, often caused by sitting too long. It can be serious if the clot breaks off and travels to the lungs. SO GET WALKING!
