biological aging
progressive decline in physical functions
Biological aging refers to the gradual decline of physiological functions and systems within the human body that occur over time. This process results from a combination of genetic factors, environmental influences, and lifestyle choices. As we age, various cellular and molecular changes take place, including the accumulation of damage to DNA, protein cross-linking, and the shortening of telomeres, which are specialized structures that cap the ends of chromosomes.
These changes can lead to the deterioration of the immune system, reduced energy metabolism and impaired cognitive and physical capabilities. Other effects of biological aging include increased susceptibility to chronic diseases such as cancer, cardiovascular disease, and neurodegenerative disorders like Alzheimer’s and dementia.
While biological aging is a natural process, there are interventions that can slow its effects, including regular exercise, a healthy diet, getting adequate sleep, managing stress, and avoiding smoking or excessive alcohol consumption. Additionally, certain anti-aging therapies have been shown to be effective in slowing the rate of biological aging. These include caloric restriction, intermittent fasting, and the use of certain supplements and hormones, although further research is needed to establish their long-term efficacy and safety.
