Understanding Biological Age and the Aging Process
Biological age refers to how a person has aged based on their appearance and health compared to their chronological age. Research suggests that biological age can be controlled and possibly slowed through certain lifestyle changes. Aging is driven by a universal ticking clock within our biology, with a mortality rate doubling time of approximately eight years. Various factors, such as exercise and strength training, can slow the aging process by reducing the risk of age-related diseases and maintaining overall health. Understanding the underlying processes of aging can help develop interventions and treatments to delay or reverse its effects.
Assessing Biological Age and Anti-Aging Interventions
Biological age can be assessed through various means, including epigenetic clocks that measure changes in DNA methylation over time. Higher biological age is associated with an increased risk of diseases and premature death. Anti-aging interventions aim to slow or reverse biological age. One potential approach is calorie restriction, following a healthy diet while consuming fewer calories. Exercise, including cardiovascular workouts and strength training, can also slow the aging process. However, more research is needed to fully understand the effects of these interventions on human longevity.
The Role of Genes and Lifestyle in Lifespan
While genetics can influence lifespan to some extent, the majority of how long a person lives is determined by lifestyle choices. Research suggests that approximately 5-20% of lifespan is determined by genetics, highlighting the significant impact lifestyle factors have on longevity. Adopting healthy habits, such as regular exercise, balanced diet, and avoiding smoking, can help individuals maintain a healthy weight and reduce the risk of age-related diseases. While genetics plays a role, individuals have the power to take control of their aging process through lifestyle choices.
The Impact of Luck and Randomness on Aging
Luck and randomness can significantly influence the aging process. Aging is not solely determined by genetics and lifestyle choices, as chance factors play a role as well. Factors such as random mutations, cellular fumblings, and unpredictable incidents can contribute to the aging process. While individuals can make efforts to mitigate certain risks, there are aspects of aging that remain inherently random. Understanding and accepting the role of luck in age-related processes emphasizes the need for a comprehensive approach to healthy aging.
The Importance of Sun Protection and Oral Hygiene for Aging
Sun protection and oral hygiene are important aspects of healthy aging. Sunlight's ultraviolet rays can damage the skin's DNA and lead to mutations, increasing the risk of skin cancer and aging-related changes in the skin. Regular use of sunscreen and covering up can help minimize these risks. Additionally, maintaining good oral hygiene is linked to overall health and may reduce the risk of heart disease and potentially other age-related conditions. Chronic inflammation caused by oral diseases like gum disease can contribute to various health issues, highlighting the importance of oral health in the aging process.
How would you like to slow, stop or even reverse your body’s ageing? Although that might sound like science fiction, a growing body of research suggests that ageing isn’t inevitable, that you can control a large proportion of how you age.
How exactly? That’s just what we’ll be unpacking across two episodes with guest Andrew Steele, the author of Ageless: The new science of getting older without getting old. In this first part of our anti-ageing special, we’ll go through how to assess your own biological age, and how to slow it with several simple lifestyle changes.
