- Advertisement -

Healthy ageing is a process of maintaining and improving one’s physical, mental, and cognitive health throughout the life course. It involves postponing or reducing the undesired effects of ageing, such as chronic diseases, disability, and dependence. Healthy ageing also means staying active, making smart food choices, getting enough sleep, limiting alcohol intake, and managing stress. Some factors that influence healthy ageing are genetics, environment, lifestyle, and social support. Healthy ageing can benefit not only individuals, but also their families and societies as a whole. The idea of healthy ageing acknowledges the significance of diverse efforts that enable older individuals to actively contribute to the development of their families, communities, and economies.

  • Physical activity or exercise is crucial for ageing well. Many studies show that exercise improves both the quality and quantity of life. It not only enhances heart and lung health, but also protects the brain, bones, muscles and mood from the effects of ageing.
  • Regular exercise helps to keep a healthy body weight. This can protect you from many diseases such as high blood pressure and type 2 diabetes, which are more common among older adults. Exercise can also lower blood pressure, reduce the risk of falls and serious injuries, and slow the loss of muscle and bone mass.
  • Muscle function declines with age. But people who exercise regularly are more likely to preserve their muscle mass as they grow older. Resistance training is especially beneficial for maintaining muscle strength and power, which are needed for daily activities and independence. Exercise can also stimulate the production of new immune cells and lengthen the telomeres, which are the protective caps of our chromosomes that shorten with age.
  • Exercise is also good for the brain. It can improve cognitive function, memory, attention and learning. It can also prevent or delay the onset of dementia and Alzheimer’s disease, as well as improve mental health and well-being. Exercise can reduce stress, anxiety and depression, and enhance social ties and emotional support.

  • Our food choices affect both our current and future well-being. Eating well can enhance our physical health and cognitive performance. We should include plenty of fresh fruits and vegetables, healthy fats, whole grains, and lean proteins in our meals. These foods provide vitamins, minerals, antioxidants, fibre, and other nutrients that protect and nourish our cells, tissues, and organs.
  • By consuming the right amount of salt (according to our body’s needs), we can regulate our blood pressure, keep our weight in check, and lower the risk of chronic diseases like type 2 diabetes and heart diseases. Salt is essential for fluid balance and nerve function, but too much can cause water retention, high blood pressure, and damage to our kidneys and blood vessels. We should limit salt intake to less than 5 grams per day, and avoid processed and fast foods that are high in salt.
  • Eating healthy can also boost our mental abilities and help us acquire and retain new knowledge. Certain nutrients, such as omega-3 fatty acids, B vitamins, iron, zinc, and magnesium, are important for brain development, memory, learning, and mood. A healthy diet can also prevent or delay cognitive decline and dementia in older adults. We should eat a variety of foods that provide these nutrients, and limit foods that are high in sugar, saturated fat, and refined carbohydrates, as they can impair our brain function and mental health.

A Good Night’s Sleep 

A Good Night’s Sleep Can Lead to Healthy Aging | KreedOn

  • Sleeping well is essential for our physical and mental well-being. As we get older, our health problems may interfere with our sleep quality. Lack of sleep can affect our mood, memory, and mental health. It can make us more prone to anger, forgetfulness, and depression. It can also impair our ability to learn and recall new information. People who suffer from sleep disorders are at a higher risk of developing dementia in their later years. This is because chronic sleep deprivation causes a buildup of beta-amyloid, a protein that is associated with Alzheimer’s disease.
  • Beta-amyloid is a waste product that is normally cleared from the brain during sleep. However, when we do not get enough sleep, beta-amyloid accumulates in the brain and forms sticky plaques that damage the brain cells and disrupt the communication between them. This leads to cognitive decline and memory loss, which are the hallmark symptoms of Alzheimer’s disease. Therefore, getting a good night’s sleep is not only important for our daily functioning, but also for our long-term brain health.

  • Smoking harms everyone, no matter how old or what gender you are. Quitting smoking is one of the best things you can do for your health. You will enjoy many benefits when you stop smoking. Some of the benefits are:
  • Reduced risk of heart attack, stroke, cancer, and lung disease. Smoking damages your blood vessels and organs and increases your chances of getting these serious illnesses. Quitting smoking lowers your risk over time. 
  • Better blood circulation. Smoking makes your blood thicker and more likely to clot, which can lead to heart problems and stroke. Quitting smoking improves your blood flow and oxygen levels. 
  • Better taste and smell. Smoking dulls your senses of taste and smell, making food less enjoyable. Quitting smoking restores your senses and lets you appreciate flavors and aromas again. 
  • More energy. Smoking makes you breathe harder and tire faster, affecting your physical activity and fitness. Quitting smoking boosts your stamina and helps you breathe easier. 
  • Less harm to others. Smoking not only affects you, but also the people around you. Secondhand smoke can cause health problems for your family, friends, and coworkers. Quitting smoking protects them from the dangers of passive smoking. 

Avoid or Reduce Alcohol Consumption

Alcohol can harm your health in many ways, so it is advisable to avoid or reduce your intake. As you get older, you may become more vulnerable to the effects of alcohol. You may also drink more to cope with loneliness or physical pain. Drinking too much alcohol can damage all your organs, especially your heart, liver, and brain. Long-term heavy drinking can also make you look older than you are.

Some of the harmful effects of alcohol on your body are:

  • Heart problems: Alcohol can weaken your heart muscle, cause irregular heartbeat, increase your blood pressure, and raise your risk of stroke and heart disease.
  • Liver problems: Alcohol can cause fatty liver, inflammation, scarring, and cancer in your liver. Your liver is responsible for breaking down alcohol and other toxins, but it can only process a limited amount of alcohol at a time. Excess alcohol can overwhelm your liver and impair its function.
  • Brain problems: Alcohol can interfere with your brain’s communication pathways, affect your memory, learning, mood, and judgement. Alcohol can also shrink your brain and increase your risk of dementia and Alzheimer’s disease.
  • Ageing problems: Alcohol can dehydrate your skin, make it more prone to wrinkles, and reduce its elasticity. Alcohol can also affect your hair, teeth, nails, and eyes, making them look dull and unhealthy.

  • Healthy ageing is the process of maintaining physical, mental, and social well-being as we grow older. Genetics is one of the factors that influences how we age and how long we live. Genetics refers to the inherited information in our DNA that determines our traits and characteristics. Some of these traits, such as eye colour or blood type, are visible or measurable, while others, such as susceptibility to diseases or longevity, are hidden or variable.
  • Researchers have identified several genes that are associated with healthy ageing and longevity. These genes are involved in various biological processes, such as DNA repair, telomere maintenance, nutrient sensing, mitochondrial function, cellular senescence, and inflammation. For example, telomeres are the protective caps at the ends of chromosomes that shorten with each cell division. Shorter telomeres are linked to ageing use and age-related diseases, while longer telomeres are linked to longer lifespans. Another example is the apolipoprotein E (APOE) gene, which affects cholesterol metabolism and brain health. Different variants of the APOE gene have different effects on the risk of Alzheimer’s disease and cardiovascular disease.
  • However, genetics is not the only factor that determines how we age and how long we live. Environmental and lifestyle factors, such as diet, exercise, stress, smoking, alcohol, social support, and education, also play a role in modulating the expression and function of our genes. Therefore, healthy ageing is the result of a complex interaction between our genes and our environment.

Focusing on Mental Health

Maintaining mental health is crucial for healthy aging, impacting our emotional well-being, coping mechanisms, and decision-making processes. It plays a pivotal role in preserving physical health, preventing chronic illnesses, sustaining cognitive abilities, and enhancing overall quality of life for older adults. Poor mental health can exacerbate physical conditions, impair cognitive function, diminish life satisfaction, and strain social connections, while positive mental health can bolster physical well-being, cognitive abilities, life fulfillment, and social interactions.

  • The correlation between mental and physical health remains pivotal, as poor mental well-being can exacerbate existing physical conditions, while Positive mental health can enhance the immune system, lower blood pressure, and reduce inflammation.
  • Preserving cognitive abilities becomes vital, and mental health greatly influences brain health care, impacting memory, attention, and learning. Depression and anxiety pose risks to cognitive function, potentially leading to dementia or Alzheimer’s disease. Conversely, engaging in mental exercises and social activities can protect the brain from the effects of ageing.
  • Enhancing life satisfaction becomes a focus, as mental health conditions like depression and anxiety can diminish happiness and meaning. On the other hand, positive mental health can foster resilience, optimism, and self-esteem while promoting positive emotions like joy and gratitude.
  • Nurturing social connections becomes a priority, given that mental health profoundly affects how seniors connect with others. Conditions like depression and anxiety can lead to social isolation and loneliness, whereas Positive mental health encourages social participation, intimacy, and stronger relationships.

Therefore, focusing on mental health can have a positive impact on healthy ageing. Older adults can improve their mental health by adopting healthy lifestyles, seeking professional help when needed, and engaging in activities that promote mental well-being, such as physical exercise, meditation, hobbies, volunteering, and socializing.


Healthy ageing is a multidimensional concept that involves not only the absence of disease, but also the maintenance of physical, mental, and social well-being in older age. It is influenced by various factors, such as biological, environmental, behavioral, and social determinants. Focusing on mental health, for example, can have positive effects on physical health, cognitive function, quality of life, and social relationships. Healthy ageing can also benefit society as a whole, by enabling older people to contribute their skills, experience, and wisdom. Therefore, it is important to promote healthy ageing through policies and interventions that address the needs and challenges of older people, and that respect their rights and dignity
