In this paper, human catabiosis has been observed from the vantage of thermodynamics. The nature of human catabiosis, its origin and future evolution are addressed. Research works on human catabiosis based on non-equilibrium thermodynamics are summarized. The origin of the human species, reproduction, growth and ageing are reviewed from the perspective of thermodynamics, and finally, the future trend of catabiosis is discussed. Works of the literature suggest that in the human body, thermodynamic entropy generation increases with the increase in age. It is valid for organs as well. Human catabiosis can be thought of as a continuous degradation of Gibbs free energy, which brings to the thermodynamic equilibrium i.e. death. The choice of dietary patterns and geographical locations also influences the ageing process. The low-calorie diet delayed human ageing. However, literature exhibits that the colder region on the earth (Oceania, Europe and North America) extend life expectancy. The future trend of longevity depends on how the entropy production will be compensated with introduction of futuristic medical aids.
