Facial feedback hypothesis stated that the movement in our face could very much influence the type of emotion that we felt.
Which mean that whenever we consciously force yourself to smile regardless the negative situations that we face in our life, we would most likely obtain the positive emotions that we need to get through it.
The facial feedback hypothesis states the idea that our facial expressions have an influence on our emotions, which affect both, others and ourselves; to the extent that without facial activation emotions could not occur.
The hypotheses regarding this subject, studied by several psychologists, date back to Charles Darwin (1872/1955) who believed that our facial expressions could enhance or inhibit the intensity of an emotion. If we smile, while we are sad, our expression of happiness will reduce our sadness.
