With depression rising worldwide, finding effective, affordable relief is a pressing global public health need. Social activity and physical activity both function as natural depression remedies, but depression can interfere with these activities. This study explores whether an increase in social activity can simultaneously increase voluntary exercise. If so, a single remedy could potentially yield two benefits. Rats were singly or paired housed to model social activity, and voluntary wheel running was measured. Depression proneness was modeled with Occidental Low-Saccharin- Consuming (LoS) rats; relative to high-saccharin-consuming (HiS) rats, LoS rats are more anxious and vulnerable to stress, both of which are risk factors for depression. Whether LoS rats would benefit more from social housing than HiS rats was of interest. Pair-housing increased wheel running, equally so among LoS and HiS rats. These results suggest that social activity may increase motivation to exercise, regardless of depression proneness.
