Physiological age is not the number of years an individual has been alive. This term is not about the longevity of people but rather how the body functions with the elderly, the young and age mates. Psychological age has everything to do with a mental status. The number of years that a person has been alive is termed as chronological age.
Just like psychological age, physiological age depends on the comparison of an individual against a chart that looks at their results versus a given average, covering different tests for the same reason. There is a very significant difference between adults and young people when it comes to physiological tests.
Things such as malnutrition at an early age may increase an individual’s physiological age. However, doing exercises and taking care of the human body triggers an anti-aging process that helps in maintaining physiological youth for a long time.
The physiological age of a person is one that is based on their appearance. Physiological age factors in things such as physical health, mental health, and other physiological factors. The chronological age of a person is what is based on the number of years that a person has been alive. Although the physiological age is based on body functioning, it is relative to the chronological age of a person. For example, when a person is 50, with no underlying health conditions and their bodies are fit and appear younger; their physiological age could be 35 or 40. This is because they appear to be 35 or 40. The physiological age of a person is greatly affected by lifestyle and biology.
