Getting older is a natural part of life. How you will feel as you get older depends on many things, including what health problems run in your family and the choices you make. If you take good care of your body and learn positive ways to deal with stress now, you can slow down or even prevent problems that often come with getting older.
It's never too early or too late to change bad habits and start good ones. No matter when you start, a healthy lifestyle can make a difference in how you feel and what you can do.
The changes you'll go through as you get older depend on a number of things. One is your family history (genetics). If your family members have diseases or ongoing (chronic) health problems like high blood pressure or diabetes, then you may have a greater chance of having those problems yourself. But just because your risk is higher, it doesn't mean you will definitely have the same problems. In fact, the lifestyle choices you make can help reduce your chances of getting illnesses that run in your family. And even if you do get a family illness, choosing to be physically active, to eat healthy foods, and to learn how to deal with stress can keep the illness from destroying your ability to enjoy your golden years.
Changes as you get older are usually gradual. Certain physical changes are common. Your metabolism (how fast your body can burn calories) slows over time, which means that your body needs less food energy than before. How much and how well you sleep will likely change. Most people start needing reading glasses around age 40, and many have some hearing loss later in life. Starting in your 50s, bone aging increases. Also starting around age 50, you may notice changes in sexual function—it's normal to have a slower sexual response.
Most vital organs gradually become less efficient with age. The kidneys are less able to keep enough water in your body. And the heart can start to show signs of wear and tear. So as you get older, it's important to be physically active, drink plenty of water, and choose healthy foods. Doing these things will help your body work well for a longer period of time.
One of the most important things you can do for your health at any age is to be physically active. Physical activity keeps your body strong, and it helps with how you feel. People who stay active are less likely to get depressed. Physical activity can be anything from walking to gardening to working out at the gym. The important thing is to be active almost every day. No matter what your age or condition, there is a type of physical activity that's right for you. Always ask your doctor whether it is safe for you to start a physical activity program.
Your mental and emotional health are also important. Protect or improve your emotional health by staying in touch with friends, family, and the community. People who feel connected to others are more likely to thrive than those who do not. And try to keep stress at a minimum. In addition to getting regular physical activity, you can take charge of how stress affects you by taking 20 minutes a day to just relax.
To protect or improve your memory and mental sharpness, keep your brain active and challenged. Learn or do something new and different. For example, attend an educational workshop or learn a new card game. Depression can be a serious problem for older adults. If you think you may be depressed, seek help—antidepressant medicine and counseling can help treat depression.
Other good health habits can help you stay at your best:
Health Tools help you make wise health decisions or take action to improve your health.
As your body ages, you can expect gradual changes, at your body's own pace. How your body ages depends in part on your family (genetic) patterns of aging. But your lifestyle choices have a more powerful impact on how well your body ages. Fortunately, you can control your lifestyle choices.
Some of the following changes may apply to you. Others may not. A healthy lifestyle may slow many of these normal effects of aging.
Skin. With age, the skin becomes less elastic and more lined and wrinkled. Fingernail growth also slows. The oil glands gradually produce less oil, making the skin drier than before. You can slow skin aging by using moisturizer and protecting the skin from the sun with sunscreen and sun-protective clothing, such as a hat or cap.
Hair. It's normal for hair to gradually thin on the scalp, pubic area, and armpits. As hair pigment cells decline in number, gray hair growth increases.
Height. By age 80, it's common to have lost as much as 2 in. (5 cm) in height. This is often related to normal changes in posture and compression of joints, spinal bones, and spinal discs.
Hearing. Over time, changes in the ear make high-frequency sounds harder to hear and changes in tone and speech less clear. These changes tend to speed up after age 55.
Vision. Most people in their 40s develop a need for reading glasses as the lenses in the eyes become less flexible (presbyopia). It's also normal for night vision and visual sharpness to decline. Also in the later years, glare increasingly interferes with clear vision. Vision changes can affect your ability to drive safely. For more information, see:
Sleep. Changes in sleep and circadian rhythm occur as you age. You will probably sleep less at night, and you may not sleep as deeply as you did when you were younger. And it's more likely that you'll wake up during the night and/or wake up earlier in the morning. For more information, see the topic Coping With Changing Sleep Patterns as You Get Older.
Bones. Throughout adulthood, men and women gradually lose some of the mineral content in their bones. The bones get less dense and strong. You can slow natural bone loss and reduce your risk of osteoporosis by getting regular, weight-bearing exercise (such as walking), getting enough calcium and vitamin D, and avoiding lifestyle choices that weaken bones (such as smoking). Your doctor may also recommend a bone-protecting medicine. For more information, see the topic Osteoporosis.
Metabolism and body composition. Over time, the body typically needs less energy, and your metabolism slows. Hormone changes in the aging body result in a shift to more body fat and less muscle mass. The best approach to managing these changes is to take in fewer calories while keeping up or increasing your physical activity. Strength training is an especially good way to build or keep your muscle mass. When your muscle mass is reduced, your metabolism slows down. Building or keeping your muscle mass allows your metabolism to remain the same or increase.
Brain and nervous system. Starting in the third decade of life, the brain's weight, the size of its nerve network, and its blood flow decrease. But the brain adapts to these changes, growing new patterns of nerve endings. Memory changes are a normal part of the aging process—it's common to have less recall of recent memories and to be slower remembering names and details. You can help keep your brain sharp. Engage in regular social activity. Challenge yourself to learn and do new things. And be physically active, to increase blood and oxygen flow to the brain.
Heart and blood circulation. The heart naturally becomes less efficient as it ages, and your heart has to work a little harder during activity than it did in the past. This makes the heart muscle a little larger. You'll notice a gradual decline in your energy or endurance from one decade to the next.
Lungs. In inactive people, the lungs become less efficient over time, supplying the body with less oxygen. Regular physical activity plays a key role in keeping your lungs strong.
Kidneys. With advancing age, the kidneys decline in size and function. They don't clear wastes and some medicines from the blood as quickly and don't help the body handle dehydration as well as in the past. This makes it increasingly important that you minimize the toxins, alcohol, and unnecessary medicine that you take in, and that you drink plenty of water.
Urinary incontinence. Age-related changes in the urinary system, decreased mobility, and some medicine side effects can all lead to urinary incontinence. This does not have to be part of normal aging, so talk to your doctor if urinary incontinence is affecting you.
Sexual function. Men and women produce lower levels of hormones starting in their 50s. Men produce less sperm, and their sexual response time slows. Women stop ovulating and have a number of menopausal changes linked to lower estrogen production. For more information, see the topic Menopause and Perimenopause.
Physical activity builds physical vitality. With every year of your life, you have more to gain from being physically active.
On a daily basis, being physically active improves your quality of life by improving your:
As you get older, an inactive lifestyle increases your risk of chronic disease. Conversely, getting regular aerobic exercise is one of your best defenses against diseases, such as:
If you already have a chronic disease, becoming physically active may reduce your need for medicine to treat or control it.
If you've been inactive for awhile, you don't necessarily have to set your sights on becoming athletic—your first goal is to simply start moving more each day. Before you do, though, get off to a smart start by seeing your doctor for a full physical examination. Then you can follow his or her recommendations as well as these guidelines for becoming more physically active.
After a few weeks of regular physical activity, you will probably feel better than before. When you're ready for more, add some variety to your activity schedule with new ways to build flexibility, aerobic fitness, and muscle strength. Experts say to do either of these things to get and stay healthy:footnote 1
It's fine to be active in blocks of 10 minutes or more throughout your day and week. You can choose to do one or both types of activity.
If you are just starting a fitness program or if you are age 65 or older, talk to your doctor about how often is safe for you to be physically active.
Even if you're happy with your fitness routine, it's a good idea to periodically stop, think, and rework your activities and goals. As age-related issues gradually enter into your fitness equation, keep the following things in mind.
Emotional and mental vitality are closely tied to physical vitality—just as your mind has powerful effects on your body, so your physical state affects how you feel and think. Social contact can also make a big difference in how you feel.
Replacing a "lost" activity is a key to staying active and feeling good about yourself. For instance, if you can no longer run, you might try walking, biking, and/or swimming. And if your favorite activity was dancing, you might try something else that combines social and physical activity, such as joining a water aerobics class. Replacing lost activities can help you keep a positive attitude and sense of well-being over time, even if aging and changes in your health mean you can not do all the things you used to do.
Physical activity. Protect or improve your emotional and cognitive health with regular physical activity. While physical activity produces chemicals in the body that promote emotional well-being, inactivity can make depression, anxiety, and stress worse. Research has been done to link physical activity and the risk of Alzheimer's disease and other dementias. Adults who are physically active may be less likely to get Alzheimer's disease or dementia than adults who are not physically active.footnote 2
Social activity. Protect or improve your emotional health by staying in touch with friends, family, and the greater community. Whether physically healthy or ill, people who feel connected to others are more likely to thrive than those who are socially isolated. Volunteering in your community and sharing your wisdom and talents with others is a gratifying and meaningful way to enrich your life.
Mental activity. Protect or improve your memory and mental sharpness by:
Stress reduction and relaxation techniques. Too much life stress can take a toll on your body, your mind, and the people who are closest to you. In addition to getting regular physical activity, you can take charge of how stress affects you by taking 20 minutes a day for relaxation time.
Positive thinking. Positive thinking may help you live a longer, happier life. Even if you tend to be an optimist, there are times when it takes extra effort to frame your life positively. Take the following steps to harness the power of positive thinking in your daily life.
Spiritual wellness. Your spiritual beliefs can bring you comfort and give you strength for handling life's challenges. For some people, organized religion provides a faith community and a belief system. But spirituality can take many forms. Taking time to be in nature, to meditate, or to pray may help you find a sense of meaning and purpose. For more information, see Spirituality and Your Health.
Because sexuality tends to be a private matter, it's likely that you've heard less about sexual change than any other element of aging. Fortunately, the news is good—for most healthy adults, pleasure and interest don't diminish with age. Most people are sexual throughout their lives, with or without a partner, and some feel greater sexual freedom in their later years. On the other hand, some men and women are content to be sexually inactive.
Around age 50, men and women typically begin to notice changes in their sexual drive, sexual response, or both. Like so many other physical changes that evolve over time, these aren't signs that you are losing your sexuality. Rather, these changes are simply something to adjust to and discuss openly with your partner and/or your doctor.
As you age beyond your 50s, you may find that:
If you have noticed sexual changes that don't seem to be linked to normal aging, talk to your doctor. There are a number of medicines that can cause sexual problems, as well as health conditions that can cause sexual problems.
With a little experimentation and patience, you can adjust to sexual changes and satisfy your sexual and intimacy needs. If you think your sexual interest might be affected by a medicine or health problem, work with your doctor to correct or treat it. Talk with your partner about any misgivings you might have so you can handle them together.
With your partner, take your time to set a relaxed mood and engage in foreplay. Use a lubricant if vaginal dryness or irritation is a barrier to enjoying sex. If you drink alcohol, remember that a small amount may relax you and increase your responsiveness, but too much alcohol is not likely to be helpful.
Sexually transmitted infections (STIs) are a risk no matter what age you are. Unless you and your partner have recently been tested or you are 100% sure that you both have been monogamous for many years without infection, make sure that you practice safer sex to prevent STIs. For more information, see the topic Safer Sex.
As you get older, good nutrition plays an increasingly important role in how well you age. Eating a low-salt, low-fat diet with plenty of fruits, vegetables, and fiber can actually reduce your age-related risks of heart disease, diabetes, stroke, osteoporosis, and other chronic diseases. By eating a wide variety of foods, you can pretty easily get what your body needs, including:
As you take a look at your daily diet, remember that as you age:
People who are underweight or frail have low reserves for bouncing back after an illness or injury. In the later years, this can lead to permanent ill health or disability. If you have trouble keeping your weight up, it's critical that you take special measures to build your weight, energy, and resilience. Every day, follow your doctor's recommendations and:
If you are having trouble getting the food you need because of transportation, financial, or health problems, ask your doctor about local meal programs. Most communities have Meals on Wheels programs that can deliver food to your door. And there are meals at churches and community centers that can nourish your needs for both food and social time.
Medical prevention, regular checkups, and prompt treatment play a key role in your quality of life as you age.
Your grandparents' generation had few protections from life-threatening conditions, but you now have the advantage of immunizations and regular screenings. Screenings and immunizations may help you live a longer, higher-quality life. But there comes a time when some screening tests won't be helpful, so talk to your doctor about which tests to have.
To learn more about recommended health screenings, see the topic Health Screening: Finding Health Problems Early.
For more information, see the Interactive Tool: Which Health Screenings Do You Need?
Be an informed health care consumer. When you are concerned about a medical condition, read as much as you can about it and its possible treatments. Make a list of unanswered questions and talk to your doctor about them. Explore all treatment options before deciding how to treat a problem. And get at least one second opinion if you're considering a surgery, medicine with dangerous side effects, or experimental treatment.
Be your own best health advocate. Make it your goal to work in partnership with your doctors. In general, people who make health decisions with their doctors are happier with the care they receive and the results they achieve. It's important to share in every decision about your health. The decisions you make influence your overall well-being as well as the quality and cost of your care. Whenever you have a medical appointment:
Get organized. Feeling organized and in control of your health care can be a challenge, especially when something comes up unexpectedly. Your best approach to managing your health care is to get organized now—create a personal medical information file, including an ongoing record of your:
For more information on how to organize your medical information, see the topic Organizing Your Medical Records.
Advance directives such as a living will and a medical power of attorney can ensure that you will get the care you want if you become physically or mentally unable to make your own medical decisions. A living will states your wishes about your medical care. A medical power of attorney gives a person you choose (your health care agent) the authority to make medical decisions for you if you become unable to make these decisions for yourself. In addition to putting your advance directives in writing, also be sure to clearly communicate your choices to all family members who might be involved in your health care in the future.
