The key is knowing we have two different ages:
Our chronological age is what it sounds like - the literal number of years we’ve been alive. There’s no going back on this one.
Our biological age refers to how old our physical cells are. It turns out we have some control here!
Understanding biological age is helping longevity science unlock the secret to why some people of similar chronological ages have much longer healthspans – periods of life where they enjoy their chosen life adventures free of aging-related diseases.
The hallmarks of aging
The Hallmarks of Aging is a concept in scientific research that identifies key factors contributing to the aging process. These hallmarks are like markers that scientists use to understand how and why we age. They include a wide range of factors such as DNA damage, inflammation, and changes in cell communication. As our understanding of aging grows, so does the list of hallmarks, with new discoveries continually being added. These hallmarks help scientists develop strategies to slow down aging and improve overall health as we grow older. A review of the history of their development published in Frontiers in Aging in 2024 lists these biomarkers:
- Cellular senescence
- Mitochondrial dysfunction
- Deregulated nutrient-sensing
- Stem cell exhaustion
- Altered intercellular communication
- Chronic inflammation
- Gut dysbiosis
- Telomere attrition
- Genomic instability
- Epigenetic alterations
- Loss of proteostasis
- Disabled macroautophagy
Now it can be measured
Turning back biological aging is not a myth or wishful thinking. There are multiple proven tests that can measure epigenetic age at the genetic level, including:
- Epigenetic clock
- Measures the harmful changes caused by methylation
- Telomere length
- Measures the shortening of these protective chromosomal caps
- Transcriptomic predictors
- Tracks changes in the way our genes send correct information to cells
- Proteomic predictors
- Measures changes in the types and levels of proteins needed for good health
- Metabolomics-based predictors
- Measures the levels and balances of small molecules needed for healthy metabolism
- And combinations of the above
A reputable genetic testing company can identify and analyze your own epigenetic markers while keeping your valuable medical information confidential and safe. Here are three companies we like (Sunlighten is not affiliated with them):
All of these science-backed services analyze your DNA (through either a blood or saliva test) to determine your biological age and give you actionable info on factors like your pace of aging and risks of specific diseases – then make recommendations for lifestyle changes you can follow and track.
A proven healthspan hack
How do we know we can reverse biological aging? Because of studies like these:
- An American Heart Institute study found participants with the highest scores and healthy lifestyle choices had a biological age on average of six years younger than their chronological age.
- An eight-week study published in the journal, Aging, found that six women between the ages of 50 and 72 lowered their biological ages from 1.22 to 11 years through dietary and lifestyle changes.
- A one-year trial supported by grants from the National Institute of Health evaluated the effects of diet and exercise (alone and in combination) on 107 adults 65+ with obesity – and saw decreases of biological age by an average of 2+ years.
- Studies with both mice and human volunteers suggest that we may soon be able to chemically reprogram cells to a more youthful state.

Think and live longer
The bottom line? It’s a good idea to know your biological age, adopt a healthier lifestyle, and stay curious about the latest longevity developments and wellness treatments that may become available to you – and which we plan to update you in the LotusLife Library.
It won’t come as a surprise that we believe Sunlighten infrared technology can be one of the keys to promoting a younger biological age. While you relax in a stress-free sauna, our patented, scientifically-proven technology will boost your heart health, reduce inflammation, remove toxins, strengthen immunity, and promote good sleep – all factors in improving epigenetic health.
