The present study is aimed at answering why humans are need to lead good life only, mean to live with positive emotions. For this a model is proposed to explain the relation between the emotions and health. As per the model our senses supply input from our environment to the mind. The input stimulates the mind and the mind processes it depending on the type of personality, and produces a feeling. Based on the type of feeling, corresponding electrical signals generate from the human brain and these brain waves cause an emotion. If it is a positive emotion, it generates health promoting hormones/neurotransmitters in the nervous system. In case it is a negative emotion, it causes to release health deteriorating hormones/neurotransmitters. So, the study concludes that humans have to lead their life with positive emotions to have sound health. It means humans have to lead good life for their sake only
