Chronic diseases such as heart disease, type 2 diabetes and certain cancers affect millions of Americans.

While age, genetics and family history can influence a person’s risk, everyday lifestyle choices can also play an important role in long-term health.

The encouraging news is that protecting your health does not necessarily require dramatic changes.

According to the Centers for Disease Control and Prevention, several major chronic disease risk factors are connected to behaviors such as tobacco use, poor nutrition, physical inactivity and excessive alcohol consumption. Regular preventive care can also help identify potential health problems earlier.

For adults in their 50s, 60s and beyond, building healthier routines may be especially worthwhile. Here are nine everyday habits that can support better health as you age.

1. Make Walking Part of Your Daily Routine

You don’t need a complicated exercise program to become more active.

Walking is one of the simplest ways to add movement to your day. A brisk walk around the neighborhood, a few extra trips through the grocery store or an evening stroll can all contribute to your weekly activity.

The CDC recommends that adults get at least 150 minutes of moderate-intensity aerobic activity each week, along with muscle-strengthening exercise on at least two days. That 150 minutes can be divided into smaller sessions throughout the week.

For example, walking briskly for about 30 minutes on five days of the week would reach the recommended aerobic activity target.

Regular physical activity can support cardiovascular health, mobility, weight management and overall well-being.

If you’ve been inactive for a long time or have a medical condition that affects exercise, talk with your healthcare provider about an appropriate activity level.

2. Build More Meals Around Whole Foods

What you put on your plate day after day can make a meaningful difference over time.

Instead of concentrating on the latest restrictive diet, consider gradually replacing heavily processed foods with more nutrient-rich choices.

A healthy eating pattern can include vegetables, fruits, whole grains, beans, nuts, seeds, lean sources of protein and healthier fats.

The CDC says healthy eating can help prevent, delay or manage conditions including heart disease and type 2 diabetes. It recommends limiting highly processed foods as well as excessive added sugars, saturated fat and sodium.

A simple approach is to ask yourself one question at mealtime: What healthy food can I add to this plate?

Adding vegetables to dinner, choosing fruit instead of a sugary dessert more often or swapping refined grains for whole grains are small changes that can add up.

3. Protect Your Sleep

Sleep isn’t simply downtime. It is an important part of maintaining good health.

The American Heart Association includes healthy sleep among its key measures for cardiovascular health and says most adults should aim for approximately seven to nine hours per night.

If getting enough sleep is difficult, establishing a consistent bedtime and wake-up time may help.

It can also be useful to keep the bedroom dark and comfortable, limit caffeine later in the day and reduce unnecessary screen time before bed.

Persistent insomnia, loud snoring, gasping during sleep or excessive daytime fatigue shouldn’t simply be dismissed as part of getting older. Consider discussing those symptoms with a healthcare professional.

4. Don’t Smoke — and Make Quitting a Priority If You Do

Few lifestyle changes have as much potential to improve long-term health as avoiding tobacco.

Smoking is associated with numerous serious illnesses. The CDC notes that quitting smoking lowers the risk of heart disease, cancer, type 2 diabetes, lung disease and premature death — even among people who have smoked for years.

That means it is not necessarily “too late” to benefit from quitting.

People who have tried unsuccessfully in the past shouldn’t assume another attempt won’t work. Counseling, support programs and smoking-cessation treatments can make quitting more manageable.

5. Spend Less of the Day Sitting

Exercise matters, but what you do during the rest of the day matters too.

Modern life makes prolonged sitting incredibly easy. We sit while driving, eating, watching television, working and using computers.

The CDC’s advice is straightforward: move more and sit less. Even adults who aren’t meeting the full weekly exercise recommendations can receive health benefits from adding some physical activity to their routine.

Look for small opportunities to move.

Stand up during television commercials. Walk around while talking on the phone. Park slightly farther from a store entrance. Take the stairs when appropriate. Spend a few minutes working in the yard.

None of these changes seems particularly impressive by itself. Combined consistently, however, they can make your lifestyle considerably less sedentary.

6. Make Strength a Priority as You Get Older

Cardiovascular exercise often gets the most attention, but strength training deserves a place in a healthy aging routine as well.

Adults are advised to perform muscle-strengthening activities involving the major muscle groups at least two days each week.

Strength training doesn’t necessarily mean lifting heavy barbells at a gym.

Depending on your fitness level, resistance bands, handheld weights and certain bodyweight exercises can provide resistance training.

For older adults, maintaining strength can also support the ability to perform everyday activities and remain independent.

Start at an appropriate level and progress gradually. Anyone with physical limitations or health concerns should speak with a healthcare professional about which exercises are appropriate.

7. Pay Attention to Alcohol

For some people, alcohol quietly becomes part of an everyday routine — a drink with dinner, another while watching television and perhaps several more on the weekend.

Over time, excessive alcohol consumption can increase the risk of significant health problems.

The CDC says excessive drinking is associated with high blood pressure, heart disease, stroke, liver disease and several cancers.

If you drink alcohol, paying attention to how much and how often you drink can be worthwhile.

And if you don’t drink, there is no health requirement to start.

8. Know Your Important Health Numbers

You can feel perfectly normal while certain chronic disease risk factors are developing.

High blood pressure, elevated cholesterol and abnormal blood sugar may not always produce obvious warning signs early on.

That’s one reason routine healthcare becomes increasingly important with age.

The American Heart Association identifies blood pressure, blood glucose and cholesterol among the major factors used to assess cardiovascular health.

Don’t simply get the tests and forget about them. Ask your healthcare provider what your numbers mean and whether they have changed over time.

Depending on your age, medical history and individual risk factors, your doctor may recommend additional screenings.

Catching a potential problem early can provide an opportunity to address it before complications develop.

9. Keep Up With Preventive Care

One of the easiest health habits to overlook is simply going to the doctor when you aren’t sick.

Preventive healthcare is designed to identify potential problems before they become more serious.

The CDC recommends regular medical and dental care and appropriate preventive services to help prevent chronic disease or detect certain conditions earlier.

Depending on your age and personal risk factors, preventive care may include blood pressure checks, cholesterol testing, diabetes screening, vaccinations and recommended cancer screenings.

Your healthcare provider can help determine which screenings are appropriate for you and how often you should receive them.

Small Changes Can Make a Meaningful Difference

There is no single food, supplement, exercise or morning routine that guarantees protection from chronic disease.

Long-term health is influenced by many factors, including genetics, age, environment, medical history and lifestyle.

But many of the everyday choices that support better health are surprisingly straightforward: move regularly, eat nutritious foods, avoid tobacco, get adequate sleep, limit excessive alcohol use and stay current with preventive healthcare.

The American Heart Association similarly emphasizes diet, physical activity, avoiding nicotine, healthy sleep, weight management, cholesterol, blood sugar and blood pressure as important components of cardiovascular health.

Most importantly, don’t assume you need to overhaul your entire life overnight.

Choose one realistic improvement and make it part of your normal routine. Once that habit becomes easier, add another.

Healthy aging is rarely the result of one dramatic decision. More often, it’s built from ordinary choices repeated day after day.
