The immune system works in coordination with other structures in the body to prevent infections from occurring and to fight existing infections. The immune system plays a role in the formation and regulation of almost every disease and therefore has a very important place for human health. Researches show that the regulation of internal and external factors that can affect immunity can be effective in protecting against diseases and in the healing process. In this review, nutrition, exercise-sports, regular life, sleep, environmental factors, addictive substances, psychological state, previous illnesses, and genetic predispositions, affecting immunity are discussed. A diet composed by adequate and balanced intake of macro and micro nutrients ensures that the immune system works at the desired level. In addition to nutrition, moderate intensity regular exercise, regular life and quality sleep contribute to immunity by affecting various physiological mechanisms. On the other hand, external factors such as previous diseases, air pollution, radiation, various synthetic compounds and harmful habits such as stress, alcohol, cigarettes and drugs can disrupt the immune system by disrupting the cytokine balance. Although genetic factors are important in immunity, it seems that lifestyle which includes factors such as diet, daily activities, sleep patterns, habits, and moods is much more determinant for strong immunity.
