God has designed our biology and physiology to make us happy. Happy hormones generally refer to endorphins, and research shows that serotonin in particular, lingers in your system after exercise and can be released by maintaining a positive mood. Dopamine is released when you move toward a goal, and oxytocin is activated through physical contact, intercourse, childbirth. These are actually neurotransmitters and your body’s natural pain killers. Work is being done where they are increasing people’s happiness and seeing their productivity going up by 31%. It’s a predictor of longevity just like smoking, high blood pressure and obesity have correlations with premature death. Happy people feel more secure, decide easier, have more cooperative behaviour and finally have a satisfying life in today's dynamic and changing environment (Vinhoven, 1993).
