Short answer
¿What does longevity mean?
Longevity means living a long life. It refers to the length of time a person lives, while healthy longevity also considers how well they live: their health, physical and mental abilities, and quality of life as they grow older.
Longevity (noun): “long life; the fact of lasting a long time”
– Oxford Advanced Learner’s Dictionary
Longevity vs healthspan
Longevity and healthspan are related, but they are not the same. Longevity refers to living a long life, while healthspan describes the years spent in good health, without significant illness or disability. The terms are related, but they describe different aspects of ageing: how long a person lives and how much of that time is lived in good health.
A longer life does not automatically mean a longer healthspan. Two people may live to the same age yet experience different levels of health, mobility and cognitive function. Healthy longevity brings these two goals together: living longer and preserving health and function throughout those years. In everyday terms, this means maintaining the ability to move, think, connect with others and take part in activities that make life meaningful.
Healthspan (noun): “the part of a person’s life during which they are healthy”
– Oxford Advanced Learner’s Dictionary
What happens biologically as we age?
Science understands ageing as a complex biological process in which changes accumulate in cells and tissues, gradually affecting how the body functions and increasing vulnerability to disease. These changes involve several interconnected mechanisms, often called the hallmarks of ageing. They include damage to DNA, changes in how genes are regulated, reduced efficiency of the structures that produce energy inside cells, and chronic inflammation. Together, they help explain why the body can become less able to repair damage and recover from illness or other stresses over time.
Longevity research investigates why some people live longer and how more of those years can be spent in good health. It explores the interaction between biological ageing, genetics, lifestyle and the environment, with the aim of preserving physical and cognitive function and delaying age-related disease. In everyday terms, the goal is to maintain the capacity to move, think and live independently for longer. Understanding the mechanisms of ageing provides promising research directions, but it does not mean that scientists can reliably stop or reverse ageing in humans.
There is no single key to longevity
The strongest foundation for a longer, healthier life is a combination of sustained healthy habits, appropriate healthcare and supportive living conditions. Avoiding tobacco and alcohol, staying physically active and eating a balanced diet are established ways to reduce the risk of diseases that can shorten life and affect its quality. These actions work together over time; no individual food, supplement or routine can guarantee a long life.
Longevity is also shaped by genetics, the environment and access to care, so it is never entirely within an individual’s control. A useful starting point is to consider both your current health and the abilities you want to preserve: staying mobile, thinking clearly and continuing to do what matters to you. Healthy ageing involves maintaining these capacities, with care and support adapted to your needs.
The ZEM approach to Longevity, by Dr Carlos Gutiérrez: “We do not view longevity science as a single intervention or the outcome of one particular technology. We understand it as an ongoing process that begins with gaining a better understanding of our own health and continues through decisions that, sustained over time, can help us preserve it”.
What can we actually influence?
Beyond the established foundations of healthy living, maintaining regular sleep patterns and strengthening social connections are two areas worth attention.
A study published in Sleep followed 60,977 participants and found that people with more consistent sleep–wake patterns had a lower risk of death during follow-up. Sleep regularity was a stronger predictor of mortality than sleep duration in this study. This suggests that when you sleep deserves attention alongside how long you sleep. These findings highlight sleep regularity as a promising area for long-term health, with further research needed to establish whether improving it can help extend lifespan.
Social connection also belongs in a conversation about longevity. The World Health Organization (WHO) identifies loneliness and social isolation as important concerns for physical and mental health, associated with a higher risk of premature death. Making time for meaningful relationships, participating in shared activities and seeking support when feeling isolated are practical ways to address this dimension of health. These findings highlight the value of considering our relationships and sense of connection as part of caring for long-term health.
Longevity begins with understanding
More data does not necessarily mean better health. The value of diagnostics lies in interpreting what those data mean for you, and translating them into priorities, decisions and actions that can be sustained over time.
How to live longer?
One practical step towards living longer is to identify and address health risks before they cause symptoms. Feeling well does not always mean that every risk is under control: high blood pressure and high cholesterol, for example, often go unnoticed. Reviewing these factors with a healthcare professional, alongside your medical history and everyday habits, can help establish whether lifestyle changes, monitoring or treatment are appropriate. A useful starting question is: “Which risks matter most for me, and what can I do about them?” This turns the ambition to live longer into informed, personal decisions.
The ZEM Method
The ZEM Method turns health data into meaningful action. From understanding your baseline to personalising your approach, each step builds on the one before it — from knowledge and targeted intervention to a personalised blueprint for long-term health and longevity.
What is Mediterranean Longevity?
Mediterranean Longevity is not a formula. It is a way of living built over time, bringing together health, movement, nourishment, rest, connection and the environment — following the rhythms of natural light and the sun, spending time by the sea, and drawing on the simplicity of Mediterranean nourishment, with extra virgin olive oil as a thread running through this way of life.
At ZEM, we bring these elements together with personalised healthcare and multidisciplinary medical expertise, within the unique Mediterranean setting of Altea.
Which longevity interventions have evidence today?
Effective longevity care starts with identifying what needs attention and selecting interventions with evidence for improving health. Depending on individual needs, assessment may include blood tests for cholesterol and glucose regulation, cognitive testing of memory and attention, and measurements of muscle mass, strength and physical performance.
To explore ageing at a molecular level, epigenetic tests can also estimate biological age by analysing DNA methylation patterns. These are assessment tools rather than treatments: their value lies in informing appropriate care, such as managing cardiovascular risk or addressing reduced muscle function. Biological-age estimates should be interpreted alongside established clinical measures, with treatment decisions guided by evidence of benefits to health and function.
ZEM translates this assessment-led approach into programmes suited to different health priorities.
What is science investigating next?
A recent scientific review published in 2026 in Signal Transduction and Targeted Therapy brings together advances in longevity research, exploring how targeting the biology of ageing could help people remain healthier for longer and potentially extend life. It highlights three approaches: removing senescent cells (cells that have stopped dividing and can disrupt surrounding tissues) reducing the inflammatory signals they release, and exploring cellular reprogramming to restore aspects of younger cell function.
Researchers are also studying ways to support cellular energy production and the recycling of damaged cell components. Several approaches have improved health or extended lifespan in animal models. Further human studies are needed to establish which can deliver safe, lasting benefits for health and longevity.
Recent longevity research is exploring whether targeting the biological processes of ageing can help preserve health and extend life. Scientists are investigating treatments that reduce age-related inflammation, remove senescent cells (cells that have stopped dividing and can disrupt surrounding tissues) or restore aspects of cellular function. One notable study published in Nature in 2024 found that blocking an inflammatory protein called IL-11 extended lifespan in mice. This offers a promising direction for research, with studies in people needed to establish whether similar benefits can be achieved safely.
Human research is also revealing that some biological markers of ageing can respond to intervention. A 2025 analysis of the DO-HEALTH trial, involving 777 adults aged 70 and over, found that omega-3 supplementation produced small changes consistent with slower ageing on several epigenetic clocks. Combining omega-3 with vitamin D and exercise showed additional benefits on one of those measures. These findings help researchers understand how ageing-related markers respond to change; the next step is establishing whether those changes translate into longer lives and lasting improvements in health.
