When i sit for to long my feet start to go numb i am under the impression that this is poor circulation what can i do to improve it.?

May not be: Although circulatory problems may cause the symptoms you describe, you may also need to consider that sitting for a long time in the same position may be producing a compressive neurovascular problem. That is, sitting may be pressing on blood vessels or directly on nerves that then give you the sensation of numbness. Changing positions, chair, adding a pillow, or getting up often may solve it.

Probably not: Probably it's not a circulation, but more of nerve/s impingement -- so just get up and walk around more -- also walking exercise daily is good for general health and weight management -.

Numb: Probably more likely nerve compression perhaps lower back Numbness is usually not the primary symptom off vascular disease Also vascular disease is usually improved with sitting and worse with activity
