“Studies show online support groups foster positive health outcomes, including escalating good, healthy habits. People are much more likely to achieve their health goals when paired-up with others who have similar goals. Healthy habits, such as eating right, sharing best practices and exercising, can truly go viral if the proper networks are established for the right information to be passed on.
Case in point: The Center for Connected Health released a study showing how social networks benefited patients with psoriasis, a common skin condition that causes skin redness and irritation. Nearly half of the participants reported an improvement in their quality of life after joining the online support site and 40 percent reported improvement with the severity of their psoriasis.”
