He can focus more on his hobbies or he can spend time with his grandchildren. It is to be specified here that there are factors that contributes to ageing and there are factors that delays ageing. In this chapter we will be focusing on the factors that contribute to ageing. Senescence is the progressive deterioration of cellular growth and decline in metabolic processes, through the passage of time.
Senscence starts at the end of reproductive age and is also called as old age. There are several factors that contribute to ageing. These factors may be biological, life style, social, psychological, spiritual, and cognitive and the diseases in the old age. These factors may not only lead to ageing but also to several diseases in the ageing process.
Several biological factors like genetics, temperature, glycation, metabolism and oxidation affects the ageing process of humans.
The genes of humans are genetically programmed for ageing. The human genes consist of a protein called rapamycin that has been responsible for regulation in ageing and growth Rogers et al. There is genetic theory that longevity of life is determined by the longevity of their parents and grandparents and that identical twins have similar age span than fraternal twins Rogers et al.
The metabolism plays an important role in the regulation of ageing and growth. Metabolism produces reactive chemicals or oxidizing agents that may increase the ageing process due to the damage in cells. The cells of an organism are always getting damaged and worn out on daily basis. But, sometimes, permanent damage occurs to more or less permanent basis that these cannot be repaired easily, leading to ageing Rogers et al.
Ageing : Ageing is the process of transition due to getting older, leading to decline in physical and mental capacities so that the individual is not able to function that competently. Sleep Disturbances : Sleep disturbances are the irregularities in sleep pattern due to certain factors that are causing disturbances in sleep. Lifestyle Factors : Lifestyle factors are those factors that are affected by the lifestyle of a person like addiction of substances, eating behaviors, and so on.
Biological Factors : The biological factors are those factors that are occurring biologically in the individual and difficult to alter like genetic, metabolism, and wear and tear in the body. Social Factors : Social factors are those causes where the individual is affected by social support, social networking, etc. Offer does not apply to e-Collections and exclusions of select titles may apply.
