Healthy Aging: Sustainable Habits for Longevity and Vitality
What does longevity mean?
Longevity is living a long life, beyond average life expectancy.1 In the U.S., life expectancy has increased significantly since 1900. At that time, the average lifespan was 47 years.1 Today, one can expect to live around 79 years. 2
Living a longer life is a goal for many people. However, longevity depends on a variety of factors, including lifestyle habits, access to healthcare, socioeconomic status, environmental conditions, and genetics.
Healthy habits for living a healthy, long life
Reaching an advanced age does not necessarily lead to happiness, especially if it means living with a disease or disability.
Maintaining healthy lifestyle habits can contribute to a longer and healthier life. Research suggests that people who maintain a healthy diet, exercise regularly, keep a healthy weight, and avoid smoking and excessive alcohol consumption may live up to 14 years longer than those who do not follow any of these habits.3
Diet strategies for healthy aging
The prevalence of chronic conditions such as type 2 diabetes, hypertension, heart disease, and dementia increases with age.4
Evidence shows that adopting healthier eating habits helps prevent these and other age-related diseases. A healthy diet is typically:4
· High in fresh fruits and vegetables, whole grains, low-fat dairy, and lean protein.
· Low in saturated and trans fat, sodium, and added sugar.
The DASH, MIND, and Mediterranean diets are good examples of diets with the characteristics described above.4
Some multivitamin supplements may also help improve memory and cognitive function in some people.
The role of exercise in promoting longevity
Regular physical activity lowers the risk of several chronic conditions, including hypertension, diabetes, high cholesterol, stroke, and cancer. Research suggests that people who exercise regularly may live up to 6.9 years longer than those who are inactive.5
The Physical Activity Guidelines for Americans from the U.S. Department of Health and Human Services recommends that adults engage in 150 minutes of moderate-intensity physical activity per week, 75 minutes of vigorous-intensity exercise, or a combination of both. The guidelines also recommend including 2 days of muscle-strengthening activity each week.6
Sleep and longevity
Sleep is essential for overall health and well-being. Chronic sleep loss can lead to several health problems, including obesity, diabetes, heart disease, cognitive decline, depression, and anxiety. It can also reduce the body's natural defenses, making it more susceptible to infections.
Research suggests that sleeping fewer than 7 hours per night is associated with a shorter life expectancy. These findings highlight the importance of getting enough quality sleep.7
Getting 7 to 9 hours of sleep each night can bring a lot of benefits, including a lower risk of chronic diseases, improved memory and attention, better heart health and metabolism, easier weight management, and higher energy levels for daily activities.
If you’re struggling to sleep at night or regularly wake up feeling tired, consider talking to your doctor about it.
De-stress and live longer
When you’re stressed, your body releases hormones that increase heart rate and blood pressure. You may also feel tense and start sweating.
Feeling this way occasionally is normal and part of the body’s natural response to challenging situations. But chronic stress can accelerate aging and contribute to serious health problems, including digestive issues, headaches, heart disease, and sleep disturbances. Research suggests that high levels of stress may shorten life expectancy by up to 2.8 years.8
Strategies to manage stress include practicing deep breathing exercises, journaling your thoughts, practicing mindfulness meditation, spending time outdoors, or simply engaging in relaxing activities you enjoy.
If stress becomes difficult to manage on your own and starts interfering with your daily activities, consider talking to a mental health professional.
Social connections and healthy aging
Nurturing positive relationships can help you live a longer and happier life. Studies show that social isolation and loneliness are linked with a higher risk of chronic diseases. On the other hand, staying socially connected can benefit both physical and mental health, helping reduce the risk of early death.9
Reach out and spend some time with people who care about you. Joining groups or activities based on shared interests creates an opportunity to make new friends.
Key takeaways
Simple everyday habits can help support healthy aging. Focus on eating a balanced diet, staying active, getting enough sleep, managing stress, and maintaining social connections. Over time, these small changes can help you enjoy a longer, healthier life.
