What is it and
why is it relevant?
In simple terms, "healthspan" is the number of years a person is healthy. While "lifespan" (the number of years we live) has increased, the chronological age at which the majority of us start to have health problems remains unchanged.
Healthspan vs. Lifespan
In our quest to help increase healthspan, we seek to slow down the specific DNA damage thought to progress aging. Our goal is to help you feel and function better for longer.
Chronological Age (Lifespan)
Chronological age is the amount of time a person has been alive since birth. The challenge with this number is that it doesn't put into context our functioning ability and epigenetic alterations. Chronological age increases at the same rate for everyone, cannot predict mortality and certainly does not provide insight into how healthy or unhealthy an individual may feel during any given stage of adulthood.
Biological Age (Healthspan)
Chronological age answers the question, "How old are you?" Biological age, on the other hand, answers the question, "How old do you feel?" (It refers to the length of time a person feels and functions well since birth.) Biological age, aka "healthspan," is impacted by chronological age, epigenetic alterations, cellular functioning and more. Ideally, lifespan and healthspan expand at the same rate. However, this is not the case for everyone due to differences in genetics and lifestyle (lifestyle differences trigger differing levels of chemical changes affecting DNA, telomeres and cells).
Cellular Health & Your DNA
How is biological age determined?
Your cells, telomeres and DNA all determine your biological age or healthspan.
Healthy cells have a soft, permeable cell membrane, allowing functioning nutrients to get inside and waste products to get out. This process of homeostasis also enables cells to protect themselves from pathogens and supports the natural process of cellular turnover. Cellular flexibility and permeability are also associated with reduced biological age (and increased healthspan).
In contrast, unhealthy cells have stiff, rigid, less permeable cell membranes. Since they do not function efficiently, these cells reduce the nutrients delivered to the cell nucleus and keep waste inside. The result is decreased cellular energy and increased vulnerability to pathogens.
Telomeres are nucleotides on the ends of chromosomes. Think of them as the protective plastic tabs on the end of shoelaces that prevent them from unraveling.
Our DNA provides the code for how quickly healthy cells age and die. Our telomeres protect this DNA from damage. Unfortunately, the shorter they become due to epigenetic factors, the higher our biological age (aka decreased healthspan) and the more vulnerable we become to aging aggressively. Telomere lengthening and protection are well-researched subjects specific to increasing healthspan.
