Biological ageing is one of the best markers you can use to understand your health and well-being. Unlike your chronological age, your biological age provides insight into how old your body actually is, how well it is performing, and not just how many years old you are. In this article, we will provide you with more in-depth information regarding biological ageing and what it actually means for you, as well as some of the best tips you can follow to help slow down the biological ageing process.

Here are the five biggest takeaways from this article about slowing biological ageing:

• Unlike chronological age, biological age gives a more accurate picture of how well your body is functioning.

• Exercise, particularly consistent aerobic activity like running, has been shown to provide a significant biological boost.

• A healthy, balanced diet, especially one rich in polyphenols like the Mediterranean or Green Mediterranean diet, can slow the ageing process.

• Keeping cholesterol, blood sugar and blood pressure under control helps prevent age-related diseases and slows the rate of biological ageing.

• Getting good quality sleep, maintaining a healthy weight and avoiding smoking can protect your cells from damage.

Biological ageing is the ageing that occurs as you gradually gather damage to different cells and tissues in the body [1]. Unlike your chronological age, which tells you how long you have been alive, your biological age tells you how old your cells are. This can provide a better insight into how well your body is performing, and whether you need to make any changes to ensure you are living a healthy life. 

A good way to think of it is like a jumper. You may have only had the jumper for a year (it’s chronological age), but if you don’t look after it, it could carry wear and tear that would normally suggest it’s much older (it’s ‘biological age’). At Vivere, we can provide you with insights about both your biological age, as well as tailored advice on how you can live a healthier, longer life.

1 - Exercise

Engaging in regular exercise can be a useful strategy for slowing down or even reversing biological ageing. A study conducted by a Brigham Young University exercise science professor found that adults who spent 30-40 minutes running five days a week experienced almost a “9-year biological advantage” to those who did not [2]. The relationship between exercise and biological ageing may be closely linked to cellular structures called telomeres. As we age, telomeres naturally shorten which reflects wear and tear on cells. Regular exercise can have a positive impact on the length of telomeres.

2 - Eating a healthy diet

Eating a healthy diet, particularly one similar to a Mediterranean/Green Mediterranean diet, can have a significant impact on biological ageing. According to a clinical trial with contributions from researchers at Harvard T.H. Chan School of Public Health, these diets, which are rich in polyphenols (micronutrients that are found in plant-based foods like green tea), can slow biological ageing [3]. Researchers at the National Institute of Environmental Health Sciences (NIEHS) have also highlighted that biological age can be positively influenced by your nutritional choices [4]. 

3 - Controlling your cholesterol

Regulating your cholesterol levels can play a crucial role in influencing biological age. Different types of lipids, which are fatty substances, have varying effects on how fast we age. The specific kind of lipid, the length of its fatty acid chain, and its saturation all play important roles in determining their impact on ageing [5]. To effectively control your cholesterol you will need to maintain healthy eating habits, get regular exercise, maintain a healthy weight, and potentially use medication if required. 

4 - Managing your blood sugar

Managing your blood sugar levels can help to slow biological ageing, and can also have other benefits to health including enhancing lifespan. Not only does managing blood sugar levels help prevent conditions such as diabetes, but it can also help to slow general age-related cell damage [6]. Conditions like type 2 diabetes, which is affected by blood sugar levels, can also have an impact on biological ageing [7]. Type 2 diabetes, like the rate of biological ageing, can be altered and impacted by lifestyle modifications such as diet and exercise levels. 

5 - Managing your blood pressure

Managing your blood pressure is crucial in the broader context of the ageing process. Maintaining optimal blood pressure levels is key to promoting cardiovascular health and, indirectly, influencing the speed of biological ageing [8]. Again, blood pressure can be managed by simple lifestyle changes including diet, exercise and more. As well as biological ageing, controlling your blood pressure can prevent cardiovascular issues and enhance overall health.

6 - Avoiding smoking

Smoking is a well-known accelerator of the ageing process [9]. Smoking is detrimental to health for several reasons, and can impact organs, bodily functions and biological ageing [10]. Some of the ways that smoking can affect biological age include:

• Damages DNA

• Shortens telomeres

• Generates oxidative stress

• Contributes to skin ageing, damaging collagen and elastin

• Increases risk of age-related diseases including cardiovascular disease and certain cancers

7 - Sleeping well

Ensuring that you get plenty of sleep, as well as getting high-quality sleep, is important if you are looking to slow or reverse the effects of biological ageing. The quantity and quality of sleep play pivotal roles in influencing various molecular and physiological processes that contribute to the ageing trajectory [11]. Lack of sleep or sleep disturbances can create issues with metabolism, causing cellular damage, hindering body repair mechanisms and more. These disruptions can contribute to accelerated ageing biologically. 

8 - Managing your weight

Correctly managing your weight, particularly through diet and exercise, significantly improves biological age and can slow the process [12]. Maintaining a healthy weight is associated with a range of positive effects that contribute to overall well-being and may slow down the ageing process. Maintaining a healthy weight contributes to optimal metabolic function, reducing the risk of age-related conditions like diabetes and cardiovascular diseases. Weight management also aids in controlling chronic inflammation, preserving cellular integrity, and mitigating oxidative stress, all of which impact the ageing process.

Biological ageing offers a more accurate reflection of your overall health and well-being than chronological age, providing valuable insight into how your body is performing at a cellular level. By adopting key lifestyle habits such as regular exercise, a balanced diet rich in polyphenols and maintaining healthy cholesterol, blood sugar, and blood pressure levels, you can slow down the ageing process and improve your longevity. Additionally, avoiding smoking, ensuring quality sleep, and managing a healthy weight further contribute to protecting your cells and preventing age-related diseases.
