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 and allows for a healthy balance called homeostasis. When functioning nutrients get inside and waste products get out. Your healthy cells work to fight pathogens and have a life cycle where new ones are formed and old ones die. This is all part of the healthy aging process and supports or even reduces your biological age.
In contrast, unhealthy cells have hard, 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, increased unhealthy aging, and more vulnerability to pathogens. They get the nickname zombie cells because they just don’t die!
Telomeres are nucleotides on the ends of chromosomes. You can think of these as the protective plastic tabs on the end of your shoelace that prevent it 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 and more vulnerable we become to age aggressively. Protecting these telomeres and even lengthening them is noted in research to reverse biological aging.
