  • With exercise, every move you make counts

    With exercise, every move you make counts

    Just as with memory, with exercise, small bites over an extended period can generate big returns. Haley Bennett reports for BBC Science that the latest research shows that every move you make, even doing a little activity throughout the day, can improve your health and well-being.

    It’s hard to believe, but some research shows that just three minutes of intense activity periodically could reduce your risk of stroke and heart attack by about 45 percent. (Study participants were women in the United Kingdom.)

    The researchers relied on data from  tracking devices people wear on their wrists, which captures the sum total of people’s activity during the day with excellent accuracy. So, the study reflects the benefits of “vigorous gardening”  and running upstairs, which many people do throughout the day.

    Another study of middle-aged and older people who do not exercise, again based on data from tracking devices, found that just one or two minutes of vigorous activity three times a day had a 40 percent reduction in mortality within seven years relative to people who did no vigorous activity.

    Yet another study of Americans 4o and older found that inactive people who walk an extra hour add six hours to their lives. They can add as much as 11 years to their lives through additional one-hour walks.

    To be clear, many experts, along with the World Health Organization, suggest we should be exercising moderately for at least 30 minutes a day five times a week or intensely for at least 15 minutes five times a week. Such exercise levels improve both our mental and physical health. But, only about two-thirds of adults around the world do so.

    So, if you are not exercising at the moment, consider walking in place  or doing a few jumping jacks every once in a while throughout the day. Do note, though, that the benefits of classic exercising–such as lifting weights or jogging or walking quickly–are large. Engaging in “exercise bursts” does not replace the benefits of traditional exercise. Not only is traditional exercise good for your physical health, it also could strengthen your memory.

  • Want to live longer? Genes and lifestyle matter

    Want to live longer? Genes and lifestyle matter

    Dana G. Smith reports for The New York Times on the extent to which you control how long you live. How much does a healthy lifestyle help and how much do your genes determine your fate?

    For sure, we know about smokers and drinkers, people who eat junk food, as well as people who never exercise, who have lived long and relatively healthy lives. But, the data suggest that these people are the exceptions. If you want to live a long healthy life, you’d better change your lifestyle.

    According to the evidence, your behaviors will likely dictate whether you live until you’re 90. Indeed, one recent study found that you can add 24 years to your life if you: 1. eat healthy, 2. exercise, 3. get adequate sleep, 4. don’t smoke, 5. don’t drink excessively, 6. don’t take opioids, 7. manage stress and 8. engage socially. These healthy behaviors should help you to live to around 87.

    There’s little you can do to help ensure you will live to 100. But, 87 is pretty good relative to most Americans. In the US today, the average life expectancy is 78.5.

    At the end of the day, whether you live a long life depends to the greatest extent on your lifestyle, your daily habits. Genes are responsible only for about 25 percent of your longevity. Living to 100 is far more about your genes than your lifestyle.

    There are plenty of people who live very long lives without particularly healthy habits. They smoke and don’t exercise. Because of their genes, they still are not as likely to have chronic conditions, such as heart disease or cancer or dementia.

    For example, you are better off carrying the APOE2 gene if you are going to avoid an Alzheimer’s diagnosis. If you have the APOE4 gene, you are more likely to be diagnosed with Alzheimer’s. For another example, having the FOXO3 gene can keep you from getting a variety of diseases that generally come with old age.

    Unfortunately, fewer than one in 100 people have these genes. Not surprisingly, fewer than one in 100 people live to 100.

  • Blue Zones: Do they really promote long lives?

    Blue Zones: Do they really promote long lives?

    Twenty years ago, Dan Buettner started writing about Blue Zones, places on this earth where people allegedly live long healthy lives. The public has been transfixed. While people in the Blue Zones appear to exhibit good healthy behaviors, there’s no science behind the Blue Zone claims.

    Buettner has built a large following reporting on these Blue Zones–including authoring eight books–and what we can all do to live longer, healthier lives. And, he has made a lot of money doing it. But, he is making observations, not finding causal links between particular environments and longevity.

    There really migt not be a there there, Dana G. Smith reports for The New York Times. One expert challenges the notion that certain communities have more centenarians because of their special behaviors. He thinks that these communities more likely have bad record-keeping about the age of their residents.

    Why are the areas with purportedly large populations of very old people called Blue Zones? Back in 2004, researchers highlighted Sardinia in blue on a map to signal that its residents lived long lives. They thought Sardinians had especially healthier lifestyles than others or high levels of “inbreeding” leading to a certain set of genes that promoted longevity.

    Buettner, then a reporter for National Geographic, wrote about longevity in Sardinia and two other areas, Okinawa and Loma Linda, California. He argued that people lived longer in these zones as a result of their healthy lifestyles. They ate well, were active, socially engaged and didn’t smoke. Their lives had purpose, and they could handle stress.

    Buettner claimed people in Blue Zones lived ten years longer on average than the rest of us, without taking supplements or going to exercise studios. Rather, they lived in good places.

    Buettner has made “Blue Zones” into a very big business notwithstanding the lack of science behind them. Who doesn’t want to believe in magic, especially if it could help them live longer? Then, Saul Justin Newman, University College, London, decided to look into the data and things did not add up as well as Buettner has suggested.

    Newman believes the Blue Zones might not be such special places. True or not, Buettner admits that Okinawa might no longer qualify as a Blue Zone. People’s diets and lifestyles have changed. He actually believes that Blue Zones will die out in the next 15 to 25 years as a result of fast food and changing behaviors.

    We non-Blue Zone dwellers can still take a page from Buettner’s advice: eat well, stay active, and engage with your community. All three behaviors have been found to promote good health and long lives.

  • Move more, sit less

    Move more, sit less

    I plan to walk the NYC marathon in five weeks and have become very conscious of how little I move on a typical workday. I now realize that I sit for hours on end to my detriment. No more! Lydia Denworth reports for Scientific American on the benefits of moving throughout the day and the serious risks of not doing so.

    Sitting too much during the day is a danger to your health. It can cause diabetes and heart disease, among other chronic conditions. What’s interesting is that the damage of sitting is greatest when you don’t stand up periodically. It’s not so bad to sit, so long as, every hour or so, you stand and move your body.

    Why is uninterrupted sitting so bad for your health? It hurts your glucose metabolism. One recent Taiwanese study found that people who sit for hours on end without standing and moving increase their likelihood of dying by 16 percent and increase their risk of heart disease by 34 percent. Of note, cancer survivors who move more have a lower risk of death from cancer and a lower risk of death overall than people who sit around and do not move their bodies.

    To be sure, it’s worse to smoke than to sit endlessly. But, you should not minimize the dangers of sitting and not moving. You really need to walk a minimum of 20 to 40 minutes a day, and more is better.

    Exercising a bit every day is not enough if you also sit a lot. A lot of sitting is bad. Sitting keeps your vascular system from working well, especially in your legs. It also affects blood pressure, blood flow and inflammation.

    Of course, some people have to sit for eight hours a day or more. You can mitigate the risks of sitting and premature death if you exercise a lot.

    Also, keep in mind that standing without moving presents its own set of issues. Movement is key.

  • Caregiving: Keeping Parents Healthy – Water, Walking, Watch out for Delirium

    Caregiving: Keeping Parents Healthy – Water, Walking, Watch out for Delirium

    Just call me lunchmeat. Not that I’m complaining, but that’s sometimes how I feel after several years of the pressure and crunch of over-stuffed Sandwich Generation duties. Now my parents are settled into their new home,and the kids are alright. Although I’ve continued to practice geriatric psychiatry part-time, I feel like I can pry open those crusts of whole wheat and move some of those back-burner projects, like writing and sharing health care advice, to the front.

    My mother and father share a room in a nursing home, labeled the “Health Center,” in the continuing care community where they moved four years ago—I had to check my resume for the date—as it was when I last held a full-time job. Both have dementia. My father carries a diagnosis of Alzheimer’s disease. My mother has vascular dementia; her atrial fibrillation caused her heart to throw tiny blood clots to her brain, which led to “mini-strokes.”

    My parents have stayed out of the hospital for almost a year. This is a triumph for my sisters and me, and for the nurses, aides, therapists, and doctors involved in their care. I’ve come up with three basics (for starters here) that have contributed to keeping my parents healthy–water, walking and watching out for delirium. These were important when they were still in their apartment as well. They’re important for everyone.

    Water – Everyone’s heard this before but sometime’s it’s so incredibly hard to get older people (especially your mother!) to drink enough. As we age, we don’t get the ‘thirsty’ signal transmitted as strongly to our brains as when we were younger; it’s easier to become dehydrated. Lack of water can lead to low blood pressure and falls, to electrolyte imbalances and heart problems, to bladder and kidney infections, just to name a few.

    Women of my mother’s generation didn’t walk around with water bottles or some other container of liquid constantly in their hand like many of us do. In addition, as older bladders start to leak, and going to the bathroom requires help, they may hold back on fluids on purpose.

    It’s wise to ask the person you’re caring for what he or she likes to drink. As long as weight or diabetes or some other health issue isn’t a problem, give the person what she or he wants. Juices, tea, coffee, even soda, given that it’s not likely to be very much.

    A plastic cup like they have in hospitals has helped. The handle on the side makes it easy to grasp, and the top and the straw easy to sip from. Putting the person’s name on the cup and maybe a picture he or she likes can help get their attention. How about “Drink to Your Heart’s Content!” I like Alice in Wonderland; I’ll want Alice and a “Drink Me” tag on mine.

    Try to remember to offer (not just suggest) your mom (or dad) the cup as many times as is reasonable whenever you are visiting. Walk in with your own bottle (of water, juice, soda) and say, “I hate to drink alone”, or just “Cheers.”

    Walking – The maintenance of strength, balance, and flexibility as well as getting one’s heart pumping continue to be important whatever your stage of life. Exercise is at or near the top of the list for keeping your brain healthy too. An increasing number of studies show that exercise appears to slow the decline in memory and other brain functions in people who have dementia.

    My father continues to visit the same gym he frequented before joining my mother to live in the nursing home. He pedals the stationary bike and lifts light weights twice weekly with the encouragement and under the supervision of the physical training staff. He looks forward to going to see “the girls,” though he no longer remembers their names. One of my sisters or I must accompany him to the gym (and back), as the building is a couple of blocks from where he lives, and he can no longer navigate there himself.

    My mother goes to physical therapy twice weekly. The therapy room is in the same building as where she lives, so it’s easy for staff to come for her. It’s also another social outlet, with the therapists and other residents. The cost is out-of-pocket and about $60 an hour (per session), comparable to personal-training sessions. (But, Medicare should cover some physical therapy costs if your doctor prescribes it to maintain or restore function and it is provided by a Medicare-certified therapist.) My sisters and I also get both parents walking whenever we can—outside when it’s not too hot (in south Florida).

    Watching for delirium – When my mother told me, “They took me in the middle of the night to a shack in the boonies, a place in the swamp with nothing around except grass that swished all night with the rain . . . ,” I called her doctor to tell her my mother very most likely had another bladder infection and needed to be treated ASAP.

    Although she was speaking perfectly coherently on the phone, my mother had been delirious the night before. She could acknowledge the improbability of the swamp scenario, although she kept referring to it. Her nurse said she had no fever, hadn’t been needing the bathroom more than usual, nor did she feel any burning sensations. This lack of specific symptoms is common in people her age.

    It’s also common for family members to be the ones to notice that mom is expressing strange ideas, or is looking more sleepy or acting more irritably than her usual self. In nursing homes, bladder, or urinary tract infections, are the most common cause of sepsis, which is infection getting into the blood and possibly into other organs. These infections account for one-third of hospitalizations of patients in long-term care facilities, and studies show mortality rates ranging from 4 to 15.5%.

    Dementia is the strongest risk factor for delirium. Even after recovering from an acute episode of an infection with delirium, brain function often worsens. Each time a person becomes delirious, it’s like the tide goes out a little further on his or her brain and never quite comes all the way back in. Besides infections, dehydration can lead to delirium, as can malnutrition, drug reactions, and lack of sensory stimulation, which can occur in an intensive care unit or with very impaired eyesight or hearing

    More about risk factors for delirium and how to recognize it can be found here from the Hospital Elder Life Program for Prevention of Delirium.

  • How to prevent falls and their sometimes horrific consequences

    How to prevent falls and their sometimes horrific consequences

    According to the National Institutes of Health (NIH), more than one in four people over 65 fall each yearand around three million end up in the emergency room or as a hospital inpatient. Falls are increasing, even though they are preventable. Falls are also costly. In the period between 2016 and 2018, the average annual cost of falls among older adults was $80 billion.

    For older adults, the consequences of a fall can be particularly horrific, restricting people’s activities, if not robbing them of their independence. According to the CDC, falls are the leading cause of injury and injury death among people 65 and older.

    How to prevent falls?

    1. Talk to your doctor about the side effects of the medications you’re taking, both prescription and over-the-counter drugs. Some medicines can make you dizzy and more prone to falls.
    2. Make your home safer. Remove any loose rugs or tack them to the floor. Install grab bars in the bathroom. Use night lights.
    3. Stand up slowly after sitting to avoid light-headedness.
    4. Have your eyesight and hearing checked each year.
    5. Use a cane or walker for stability.
    6. Do balance and strength exercises.
     Here are five exercises to improve balance that the NIH recommends: (more…)
  • Housekeeping is good for healthy aging, especially if you don’t sit around watching a lot of TV

    Housekeeping is good for healthy aging, especially if you don’t sit around watching a lot of TV

    New research from the Nurses’ Health Study, reported in JAMA, offers some hope for those of us who are not inclined to spend a lot of time exercising. The good news, reports Alvin Powell for the Harvard Gazette: Even the little things you do each day to move your body is good for healthy aging, including good mental and physical health.

    We know that people who are physically active are less likely to die early. But, these findings show that physical activity comes in a multitude of forms! You don’t have to exercise intensely to help your health as you age.

    If you do housekeeping or gardening and are moving around a bunch, you are ahead of the game. Though, you should still walk 20 minutes a day and get your heart rate up periodically! People who spend too much time sitting are more likely to pay a big price for their sedentary behavior in the form of memory loss or some heinous physical condition.

    Researchers at Harvard and Brigham and Women’s Hospital, among others, studied more than 45,000 people for more than two decades. Most noteworthy, they found that each incremental two hours of additional TV that some people watched, a proxy for being inactive, reduced their likelihood of healthy aging by 12 percent. But, each incremental two hours of mopping floors or tending to gardens increased people’s likelihood of healthy aging by six percent.

    What’s so bad about sitting around the TV all day, you ask? Your skeletal muscles atrophy. And, these muscles are critical for metabolizing glucose, preventing inflammation and ensuring good blood flow to your brain. And, for reasons that are unexplained, sitting around the TV is particularly harmful. Driving is better, as is sleeping.

    In short, almost anything you do other than watching TV, which requires only the most minimal physical and mental activity, will help promote healthy aging.

    Sadly, most people do not spend a lot of time moving as they age. In the study, only about one in 12 participants were sufficiently active to be aging healthily.

  • Your heart rate can help you understand your physical fitness

    Your heart rate can help you understand your physical fitness

    If you carry a mobile phone, you already track the number of steps you take each day. Other devices can help you do even more. Talya Minsburg reports for The New York Times on the benefits of tracking your heart rate.

    Smartwatches and fitness trackers will tell you a bunch about the health of your heart.  They can also track heart rate zones and changes in your heart rate. You can improve your health with this information.

    The information you can glean from smartwatches and fitness trackers can help you understand how fit you are and your fitness trends. If you’re an athlete, the information can help you with speed and endurance.

    If you don’t use a smartwatch or tracking device, you can still know your resting heart rate simply by putting your finger on your wrist or neck and counting beats for 15 seconds, Your resting heart rate is that number of beats times four.

    Healthy hearts beat about 15 to 25 times every 15 seconds or 60 to 100 times a minute. People who exercise a lot generally have lower rates.

    If you want to know your maximum heart rate, count the number of beats while you are exercising strenuously.

    Heart rate zone training can help build your endurance.  There are five heart rate zones.  Zone one is a relatively easy workout, in which you reach only about half of your maximum heart rate.

    Zones two through five require more effort. Zone two and three are good for building endurance. Zone two is a good zone for running or bicycling. Zone three takes still more effort; you might find you will need to take some breaths as you exercise.

    Zones four and five teach your body to function with less oxygen. Zone four is hard enough that you can only stay at this heart rate for a limited time.  Zone five is intense, in which you reach your full or nearly full heart rate. You cannot be talking at this level.

  • Five ways to stay fit, mentally active and purposeful

    Five ways to stay fit, mentally active and purposeful

    If you focus on birthdays, we are all getting older.  But, many of us who may be “getting up there” in age find ways to stay young at heart–fit, mentally active, and purposeful.  Here are five ways to feel at your best:

    1. Be active: Walk, run, jump rope. Get your heart rate up.  Countless studies show the value of aerobic exercise for your gut, your memory, your immune system, your cardiovascular health, your strength, your stress level, your mood, your cholesterol levels. It may be the best medicine for your body and brain. Also, do balancing exercises and use weights to strengthen your muscles. That is key to good health, including bone healthlowering risk of stroke and even spousal health
    2. Eat well and keep a healthy weight: Sense of smell and taste can change as you age; it’s still important to eat healthy foods. Eat lots of fruits, vegetables, beans, nuts, seeds, lean meats and fish. Avoid, fats, pasta and sugared drinks. And if you need help losing weight or eating better, talk to your doctor; in some cases, Medicare covers weight-loss counseling and nutrition counseling.
    3. Get the sleep you need. Here are seven tips for getting a good night’s sleep.
    4. Keep in touch with family and friends you enjoy. And make one of them your health care buddy, someone to go with you to the doctor, take notes and be a second set of eyes and ears.
    5. Perhaps, take up bowling or another new sport: Watch this video from the Atlantic on how one older adult has stayed young and met his life partner bowling.

  • What’s your cholesterol level?

    What’s your cholesterol level?

    More than 25 percent (86 million) of Americans have high cholesterol. Another 33 percent (120 million) do not know their cholesterol level. But, if you want to reduce your risk of plaque in your arteries and heart disease, as well as protect your health overall, you want your cholesterol levels under control, writes Knvul Sheikh for the New York Times.

    What is cholesterol? Cholesterol is a waxy “lipid,” or fat that your liver produces for good health. Among other things, it creates cell membranes and hormones. But, if the amount of cholesterol is not right, it can cause health problems.

    Can you have good cholesterol or is it all bad? You have two types of cholesterol, “good” cholesterol and “bad” cholesterol. If your LDL or “bad” cholesterol is high, it can cause health problems. If your HDL is high, it can reduce your risk of health problems.

    What causes high LDL cholesterol levels? If you eat too much meat and dairy products, you can create too much cholesterol. Your genes can also contribute to high LDL cholesterol levels.

    What’s the danger of high cholesterol levels? Too much cholesterol can cause heart attacks and stroke. And, you might not know you are at risk because you are not likely to have symptoms.

    When should you check your cholesterol levels? By the time you have Medicare, you should have regular cholesterol checks. But, as early as your 20’s, it’s good to check your cholesterol levels every several years. And, if you have a family history of heart attacks and stroke, you might want to get more frequent checks. Talk to your doctor.

    Your cholesterol levels will likely rise as you get older. For women, they rise after menopause.

    What should you be tracking? Track your LDL, which is the “bad” cholesterol. It should not go above 100 mg/dL and should be as low as possible.  If you have diabetes, you should keep it below 70. Your HDL, the “good” cholesterol, brings the cholesterol you don’t need back to your liver from your arteries, so you can discharge it. You want your HDL to be greater than 40 mg/dL and ideally above 60.

    How can you lower your LDL cholesterol level? Exercise more, eat healthy and avoid alcohol. Eat more whole grains, vegetables, fruits, seeds and legumes–“soluble fibers.” Eating avocados, nuts and fatty fish can also help. Don’t eat butter, cheese and red meat or ultraprocessed foods.

    Should you take drugs to lower your cholesterol? Sometimes. Especially if you’ve had a heart attack or a stroke or your LDL is high or your arteries are severely blocked.
