Our own Dr. Arpine Saribekyan (Family Medicine & Palliative Care) recommends sitting for no longer than 30 minutes at a stretch. Otherwise, these negatives can occur:
1) Ruined posture;
2) Muscle atrophy;
3) Weakened bones;
4) Slowing metabolism;
5) Poor circulation to lower extremities;
6) Contributes to sleep apnea;
7) Decreases focus and energy.
So get up and move regularly!
