Aging brings a predictable set of health challenges, but most of them respond well to straightforward habits: staying active, eating strategically, maintaining social connections, and staying on top of preventive care. The specifics matter, though. Vague advice to “eat well and exercise” isn’t enough when your body is changing in concrete ways that call for concrete responses. Here’s what actually works, based on current evidence.
Protecting Muscle Mass and Mobility
Adults start losing muscle mass as early as their 30s, but the decline accelerates after 65. This condition, called sarcopenia, is a major driver of falls, disability, and loss of independence. The good news is that it’s largely preventable with two interventions: protein and resistance training.
Most older adults don’t eat enough protein. The standard recommendation of 0.8 grams per kilogram of body weight was set for younger adults. An expert group convened by the European Society for Clinical Nutrition found that healthy adults over 65 need at least 1.0 to 1.2 grams per kilogram per day. For a 150-pound person, that works out to roughly 68 to 82 grams of protein daily. Spreading it across meals helps your muscles absorb it more effectively than loading it all into dinner.
Resistance training is the other half of the equation. This doesn’t mean heavy barbells. Bodyweight exercises, resistance bands, light dumbbells, or even standing up from a chair repeatedly all count. The key is consistency: aim for balance and strength training at moderate or greater intensity on three or more days per week. Paired with adequate protein, this combination can slow or even reverse muscle loss well into your 70s and 80s.
Keeping Your Heart Healthy
Heart disease remains the leading cause of death for older adults, and blood pressure management is one of the most effective levers you have. The 2025 guidelines from the American Heart Association and American College of Cardiology now encourage adults aged 65 to 79 to aim for a systolic blood pressure below 120 mm Hg when treatment is well tolerated. For those 80 and older, targets become more personalized, especially for people who are frail or experience dizziness when standing.
Beyond medication, the World Health Organization recommends at least 150 to 300 minutes of moderate-intensity aerobic activity per week. That’s roughly 20 to 40 minutes a day of brisk walking, cycling, swimming, or anything that raises your heart rate enough to make conversation slightly harder. Even modest increases in activity, like walking 10 extra minutes a day, produce measurable cardiovascular benefits when sustained over time.
Building Stronger Bones
Osteoporosis makes bones fragile enough that a minor fall can cause a fracture, particularly in the hip, spine, and wrist. After 65, bone density drops steadily in both men and women, though the decline is steeper for women after menopause.
Calcium is the primary building block for bone maintenance. The National Institutes of Health recommends 1,200 milligrams per day for adults over 70. Dairy products, fortified plant milks, leafy greens like kale and broccoli, and canned fish with bones (like sardines) are all reliable sources. Vitamin D is equally important because it helps your body absorb calcium. Many older adults are deficient, partly because skin becomes less efficient at producing vitamin D from sunlight with age. A blood test can identify whether you need supplementation.
Weight-bearing exercise, including walking, dancing, and stair climbing, stimulates bone remodeling and slows density loss. Combined with the balance training mentioned earlier, this also reduces the risk of the falls that make osteoporosis dangerous in the first place.
Eating for Brain Health
Cognitive decline isn’t inevitable. Diet plays a larger role than most people realize, and one eating pattern in particular has strong evidence behind it. The MIND diet, developed by researchers at Rush University, combines elements of Mediterranean and heart-healthy eating patterns with a specific focus on brain-protective foods.
The framework is practical: at least three servings of whole grains per day, six or more servings of green leafy vegetables per week, five servings of nuts per week, berries at least twice a week, beans four times a week, poultry twice a week, and fish at least once a week. Olive oil serves as the primary cooking fat. Research from Harvard’s School of Public Health found that people with the highest adherence to the MIND diet had a 53% lower rate of Alzheimer’s disease compared to those who followed it least closely.
You don’t have to overhaul your diet overnight. Even moderate adherence to the MIND pattern showed meaningful benefits. Adding a daily salad with leafy greens, snacking on nuts instead of chips, and swapping red meat for poultry or fish a few times a week are simple starting points.
Getting Better Sleep
Sleep architecture changes with age. Older adults tend to fall asleep earlier, wake up earlier, spend less time in deep sleep stages, and wake more frequently during the night. These shifts are normal, but they can leave you feeling unrested even when you’ve been in bed for a full night.
The National Institute on Aging confirms that older adults still need seven to nine hours of sleep per night, the same range as younger adults. Quality sleep supports memory formation, decision-making, creativity, and reaction time. When sleep consistently falls short, the effects compound: higher inflammation, poorer blood sugar regulation, and faster cognitive decline.
Practical improvements include keeping a consistent wake time (even on weekends), limiting daytime naps to 20 minutes, getting bright light exposure in the morning, and keeping the bedroom cool and dark. If you’re waking frequently at night or feeling excessively drowsy during the day, these patterns are worth discussing with a healthcare provider, as treatable conditions like sleep apnea become more common with age.
Staying Socially Connected
Loneliness is not just an emotional problem. It’s a physiological one. A 2024 study published in JAMA Network Open tracked older adults over time and found that increasing social isolation was associated with a 29% higher risk of death, a 35% higher risk of disability, and a 40% higher risk of dementia compared to people whose social engagement remained stable. Even among people who started out socially connected, those who became more isolated over time saw meaningfully worse outcomes.
The biological mechanism is real: isolation triggers increased expression of genes related to inflammation. Over time, this chronic inflammatory state contributes to high blood pressure, arterial disease, and accelerated aging at the cellular level. In other words, loneliness doesn’t just feel bad. It damages the body in measurable ways.
Combating isolation doesn’t require a packed social calendar. Regular phone calls, volunteering, group exercise classes, faith communities, or even a recurring coffee date with a neighbor all count. The consistency of connection matters more than the size of your social circle.
Managing Multiple Medications Safely
Polypharmacy, the use of multiple medications at once, is extremely common in older adults. Many seniors take five or more prescriptions, and each additional drug increases the risk of harmful interactions, side effects, and hospitalizations. The National Institute on Aging has called attention to “deprescribing,” the process of carefully reducing unnecessary medications.
Start by creating one complete, accurate list of every medication you take, including over-the-counter drugs and supplements. Bring this list to every medical appointment. For each medication, know its name, what it’s for, how often you take it, and how long you’re supposed to continue. Ask your provider directly: “Do I still need this one?” Medications that were appropriate five years ago may no longer be necessary, and stopping them can sometimes resolve side effects you’d attributed to aging itself.
Staying Current on Vaccines and Screenings
Preventive care becomes more important after 65, not less. The immune system weakens with age, making certain infections more dangerous. The CDC’s 2025 immunization schedule recommends two doses of the recombinant shingles vaccine for adults 65 and older. Shingles affects roughly one in three people during their lifetime, and the risk of severe complications, including chronic nerve pain, rises sharply in older adults. Pneumococcal vaccines are also recommended for this age group, with the specific type depending on your vaccination history. A newer RSV vaccine is now available for older adults as well.
Annual screenings for blood pressure, cholesterol, diabetes, and certain cancers remain essential. Many of these conditions develop silently, producing no symptoms until they’re advanced. Catching them early, when they’re most treatable, is one of the simplest and most effective things you can do for your long-term health.
