ABSTRACT
The concept of Mizaj exists in Unani System of Medicine for thousands of years and it plays a pivotal role in determining the physiological and psychological status of the human individuals. The decision making and energy level are very important aspects to determine the status of an individual in the society as well as to achieve positive goals in life. As we see some persons cannot adjust properly in the society only because of their internal physiological status that changes their behaviour and they become unsocial although they themselves would not like it. In the present study, the decision making and energy level were assessed in eighty individuals comprising of twenty representatives from each constitution, viz. Damvi Mizaj [Sanguine humor], Balghami Mizaj [Phlegmatic humor], Safrawi Mizaj [Bilious humor] and Saudawi Mizaj [Atrabilious humor]. They were subjected to the psychological tests based on a questionnaire comprising of the questions related to above parameters. After proper assessment, very interesting results were revealed, e.g. it was revealed that the individuals of Safrawi temperament have maximum level of energy, while the Saudawi individuals showed less energy level
