Visualization strategies may backfire on consumers pursuing health goals

Using visualization as motivation is a common technique for achieving goals, but consumers who are pursuing health goals such as eating healthy or losing weight should use caution when using perspective-based visualizations, a new study has found. Adopting a third-person perspective, by viewing one’s self through an observer’s eyes, may backfire when the goal is not a core part of […]

Replacing sitting time with physical activity associated with lower risk of death

For those who get the least amount of physical activity, replacing a half hour of sitting time with physical activity was associated with up to a nearly 50% reduction in mortality, according to a new study from the American Cancer Society. The study, appearing in the American Journal of Preventive Medicine, suggests that replacing modest amounts of sitting time with […]
