Get Up and Join the Movement
As we emerge from the doldrums of winter hibernation and COVID-19-related inertia, it’s important to remember that exercise is good medicine and there’s no better time than now, to get moving again.
“There isn’t a chronic condition that can’t be better managed with an appropriate dose of exercise,” asserts Dr. Cedric Bryant*, President and Chief Science Officer at the American Council on Exercise. “This requires good interaction with your physician, an ability to listen smartly to your body and the realization that some exercise is always better than none.”
He recommends fostering good muscular fitness and enhancing strength, flexibility and balance with the exercise routine shown below. The 15-minute investment of time needed to complete one set of 8 to 15 repetitions for each exercise provides beginners with “the minimum effective dose needed to elicit a very positive response,” says Dr. Bryant.
Add regular rounds of exercise that build endurance, helping improve the health of your heart, lungs and circulatory system. To achieve the best results, you should have enough breath to talk but not enough to sing during aerobic activities such as brisk walking or jogging, dancing, biking, swimming, climbing stairs, or playing basketball, tennis or the uber-popular pickleball. (Learn more about today’s fastest-growing sport in an upcoming newsletter.) Be sure and check with your healthcare provider before beginning an exercise program.
Dr. Bryant’s Essential Seven
Benefits: Develop the large muscles of the chest and the back of arms
The basic incline pushup is done using a sturdy table or other solid surface about 3 feet high. Stand facing the table and place your hands on the edge (shoulder width apart) arms straight and elbows not locked. Walk your feet backward until your arms and body are in a straight line. Bend elbows and slowly lower chest to the edge of the table while inhaling. Keep body straight and rigid throughout the movement. Push body away from the table until elbows are extended but not locked. Exhale as you push up.
2. Bodyweight Squat
Benefits: Strengthens and tones the lower body
Stand with your feet slightly more than hip width apart, toes turned slightly outward, hands at sides with palms facing in. Pull shoulders down and back. Stiffen your core and abdominal muscles. Hold chest up and out, tilt head slightly up, shift weight back onto your heels while pushing hips toward the wall behind you.
Downward phase: Shift hips back then down to create a hinge-like movement at hips and knees. Try to control the amount of forward movement of the shinbones. Maintain tension in the core muscles and keep your back straight. Lower yourself until thighs are parallel or almost parallel with the floor. DO NOT go deep enough to cause pain. Make sure your feet don’t move, ankles don’t collapse in or out, knees remain aligned over the second toe, and body weight is evenly distributed between balls and heels of the feet.
Upward phase: Extend the hips and knees by pushing your feet into the floor. Hips and torso should rise together while heels are flat on floor and knees are aligned over the second toe. Continue extending until you reach the starting position.
Remember to inhale on the way down and exhale on the way back up.
3. Bent-Over Row
Benefits: Targets muscles in the upper and middle back and improves stability of the spine
Holding a small weight in each hand and standing with feet hip-distance apart, bend at the waist. Your back should be parallel to the floor with a neutral, not rounded, spine. Extend arms toward floor, keeping knees slightly bent. Engage abs and squeeze shoulder blades together as you bend elbows back and bring weights to your torso. Keep arms close to your torso. Slowly lower the weights back to the starting position.
4. Modified Single-Leg Deadlift
Benefits: Strengthens and tones gluteals and helps improve balance
Position yourself by a wall or chair. Stand straight, with feet aligned with hips, and shift weight to right leg. Slowly bend forward at the waist while raising your left leg behind you until your torso and leg are both parallel to the floor. Keep your head up and arms straight, perpendicular to the floor. Lower your leg as you return to an upright position. Keep your leg straight at all times. Repeat all reps on one side, then switch legs.
5. Overhead Front Press
Benefits: Increases shoulder strength and engages the core for stability
Stand upright and keep the back straight. Note: Beginners or those with back issues can perform this exercise seated. Hold a small weight in each hand at the shoulders, with an overhand grip. Thumbs are on the inside and knuckles face up. Exhale as you raise the weights above the head in a controlled motion. Pause briefly at the top of the motion. Inhale and return the weights to your shoulders.
6. Calf Raises
Benefits: Strengthen lower leg muscles, increase stability, balance and agility
Start by standing 6 to 12 inches away from a wall, facing it, with feet hip width apart. Extend arms to place your palms on the wall, level with chest or shoulders. Exhale and slowly lift heels off the floor, keeping knees extended without rotating your feet. Use your hands on the wall to support your body. Hold raised position briefly. Inhale and slowly lower heels back to the floor.
7. Plank Pose
Benefits: Strengthens the core and abdominals while increasing stability and balance
Modified version: Start in tabletop position with hands and knees on the floor. Walk your hands so your forearms and palms are facing down, keep shoulders and elbows aligned. Walk your knees away from your body until you feel your core and abdominals engaged. Keep torso straight and rigid, your body in a straight line from ears to knees with no sagging or bending, and with shoulders down, not creeping up toward your ears. You may keep your toes on the floor for extra support. Hold position for 10 seconds. Walk your knees back in, repeat. Over time, work up to 30, 45 or 60 seconds.

Breaking the Cycle of Anxiety, Insomnia and Sleep Anxiety
A good night’s sleep does more than refresh and revitalize. It’s essential to your health, so make it a priority to understand what’s keeping you up at night.
“Healthy sleep is as important as proper nutrition and regular exercise for our physical and mental well-being,” says Kannan Ramar, MD, sleep medicine physician at the Mayo Clinic’s Center for Sleep Medicine and immediate past president of the American Academy of Sleep Medicine. “Lack of sufficient sleep is associated with increased risks of type 2 diabetes, high blood pressure, cardiovascular disease, depression and anxiety.”
The sleepless nights and drowsy days previously experienced by one out of three Americans with insomnia rose to pandemic highs of almost 60% in 2021, sounding a wake-up call to address this treatable condition which profoundly impacts both mental and physical well-being.
Sleep disturbance is intricately interconnected with the presence of issues such as anxiety and depression, each influencing the others, so it’s not always possible to determine which came first. Behavioral changes that result from chronic insomnia include feelings of being overwhelmed, inability to concentrate, irritability, nervousness, restlessness, and a sense of impending danger or doom.
Of adults diagnosed with depression, 75% experience insomnia and 20% have obstructive sleep apnea. Similarly, anxiety can make it harder for the body to relax and fall asleep.
Research suggests that anxiety can also affect rapid eye movement (REM) during slumber and trigger vivid, disturbing dreams that wake the sleeper.
Completing the loop is sleep anxiety — apprehension or fear about going to sleep — which is commonly seen in those with insomnia, narcolepsy, sleep apnea or restless legs syndrome.
While insomnia can seem never-ending, a number of strategies can effectively break the cycle.
- Set boundaries for blue light exposure by turning off tv, tablets and phones at least 30 minutes before bedtime.
- Limit large meals, caffeine and alcohol within 3 to 4 hours of bedtime, which can disrupt sleep. Alcohol allows you to fall asleep quickly but not stay asleep throughout the night.
- Establish a consistent wake-up time seven days a week.
- Ensure your bedroom is a designated place of sleep by keeping it dark, cool and quiet. And turn around your clock so you can’t see the time if you’re tossing and turning in the middle of the night.
- Pursue support if you are experiencing chronic insomnia, defined as difficulty sleeping three or more times per week for at least three months. “We know that the longer insomnia lasts, the more difficult it is to treat,” says Dr. Ramar.
Support can include:
- Cognitive behavioral therapy for insomnia (CBTI), a form of talk therapy focused on learning how to create an optimal sleep environment with positive bedtime routines and avoidance of factors that trigger anxiety and negative thinking. Requiring up to 12 weeks to see results, the key is shifting from “trying hard to sleep” to “allowing sleep to happen,” according to Stanford Health.
- Prescription sleep hypnotics, such as Ambien or Lunesta. Hypnotics can be considered in conjunction with CBTI, but patients must be closely monitored for adverse effects and a buildup of tolerance to the medication’s effects. Low doses of Trazodone, an antidepressant, are sometimes used, as it causes drowsiness.
- Light therapy, which is especially helpful for those who need to reset their circadian rhythms; e.g., a night owl who wants to function better with an early morning rising time.
If you are experiencing too many wakeful nights, please let your healthcare provider know. It may be helpful to keep a sleep diary for several weeks to help pinpoint the habits affecting your ability to fall and stay asleep. In some cases, we may recommend a polysomnography (sleep study), where you’ll be monitored for blood oxygen levels, body position, breathing, electrical activity in the brain, eye and leg movements, heart rates and rhythms, sleep stages and snoring during an overnight stay in a sleep lab.
Finally, keep in mind that the amount of sleep needed per night – typically 7 or 8 hours on average – varies by individual. “If you function well and are fully alert during the day, you can be confident your sleep needs are being met,” says Dr. Ramar.
Definitive Diagnostic Tool or Part of a Greater Health Matrix?
It’s an easily understood calculation: Body Mass Index, popularly known as BMI, computes an individual’s measure of body fat as weight in kilograms divided by height in meters squared. Levels are defined as Underweight if less than 18.5, Normal weight if between 18.5 and 24.9, Overweight if between 25.0 and 29.9, and Obese if above 30. But what does BMI really tell us?
This simple formula has nonetheless sparked controversy and continued questioning: Is BMI a quick, easy and efficient way to identify weight problems and associated risk of disease in adults? Or is it an inaccurate measure because it doesn’t consider body composition, age, sex or ethnicity?
Years of debate, research and analysis now point to using BMI in a more nuanced way, suggesting that it is best employed as just one part of an initial health screening for individuals, and not as a diagnostic tool. Much more meaningful is how BMI fits with other essential measures of an individual’s health — blood pressure, blood sugar, cholesterol levels, heart rate, inflammation, physical activity, diet, cigarette smoking and family history.
Looking at BMI alone can be misleading when you consider that:
- Women tend to have more body fat than men.
- Older adults have more body fat than younger ones. Aging is associated with an unhealthy increase in body fat and an associated increased risk for prediabetes and type 2 diabetes.
- At the same BMI, the metabolic risks for people of Asian descent are higher than for Caucasians.
- People who engage in strength training two or more times per week have higher lean muscle mass than nonathletes, which can result in a higher BMI but not necessarily a higher risk of disease.
Additionally, knowing where the fat is distributed is essential in determining disease risk. The pear shape associated with women means subcutaneous fat around the hips, thighs and buttocks; more dangerous is the apple shape, which indicates visceral fat in the abdomen (waist circumference of more than 40 inches for men or more than 35 inches for nonpregnant women), which is linked to higher risk of heart disease and type 2 diabetes.
An influential study published in Nature further revealed the flaws in categorizing people as “unhealthy” or “healthy” based on BMI alone. The authors found that more than 74 million American adults were miscategorized. Nearly half of people considered overweight and 29% of those categorized as obese were actually metabolically healthy, with normal blood pressure, cholesterol and blood glucose levels. Meanwhile, 30% of those considered “normal weight” had metabolic or heart issues.
The origins of BMI help explain its limitations. In the 1830s Belgian mathematician Lambert Adolphe Jacques Quetelet developed a test intended to identify the “l’homme moyen,” or the “average man,” by taking the measurements of thousands of Western European men and comparing them to find the ideal weight. More than a century later, American physiologist and dietician Ancel Keys promoted Quetelet’s Index as the best available way to quickly screen for obesity, identifying certain BMI ranges as associated with greater risk of disease and poor health outcomes. However, like Quetelet, Keys didn’t account for different body types or ethnicities.
One other point to consider: While more intrusive and not as commonly available, methods such as measuring skinfold thicknesses, bioelectrical impedance, underwater weighing, abdominal CT scans (for visceral fat) and dual-energy X-ray absorption are more accurate than BMI for estimating body fat.
So is BMI still meaningful?
As a discussion point, or as one tool used in combination with other assessments of metabolic and skeletal health, it can be useful.
Most importantly, body fat is just one of many factors considered when evaluating individual health and risk of disease.

Coping With Sad This Winter
As we continue to weather the storm of COVID-19, seasonal affective disorder, or SAD, is once again on our radar. More subtle than an arctic blast, SAD is just as real, with just as much potential to have a chilling effect on our mood, productivity and wellness. Similar to last winter, the emotional stress and ongoing uncertainty that come with a global pandemic is unfortunately creating an ideal climate for SAD. Not surprisingly, mental health experts are expecting to diagnose and treat an increased number of people with SAD in 2022.
First discovered in the 1840s, SAD was not officially recognized as a disorder until the early 1980s, when Dr. Norman Rosenthal coined the term and categorized it as a form of clinical depression. We now know that SAD affects at least 5% of Americans; is more likely to affect women than men, those with other forms of depression or family members with the condition; and is far more common in northern regions, due to reduced natural sunlight. New research has advanced several theories as to why some people develop SAD, including: sluggish transmission of serotonin (which helps regulate mood and the body’s circadian rhythms; reduced sensitivity of the eyes to environmental light; a combination of these factors; or other reasons yet to be uncovered).
A deeper understanding of what triggers SAD and its impact on mental health has inspired a growing number of clinical treatments that can effectively neutralize its effects.
Chief among them:
Sitting in front of a bright light box for 30 to 45 minutes daily has been a treatment of choice for more than three decades, helping SAD patients with either 10,000 lux of white fluorescent or full spectrum light that shines 20 times brighter than ordinary indoor illumination. Dawn simulation, another form of light therapy, begins in early morning before patients awake by emitting a low level of light that gradually increases over 30 to 90 minutes to recommended room light level (approximately 250 lux). Enhancing indoor lighting with regular lamps and fixtures is also recommended).
Newer studies from the University of Vermont suggest that cognitive behavioral therapy (CBT), a psychological treatment aimed at providing patients with tools to change negative thoughts and behaviors, may be as effective as light therapy for treating SAD. According to the National Institute for Mental Health (NIMH), CBT adapted for SAD focuses on behavioral activation, helping SAD sufferers identify and engage in enjoyable seasonal activities to combat the ennui and fatigue they typically experience in winter.
Creating a consistent light-dark, sleep-wake cycle is important for SAD patients, who often experience hypersomnia (excessive daytime sleepiness) and insomnia (trouble falling or staying asleep).
Antidepressant medications. Because SAD is associated with disturbances in serotonin activity, antidepressant medications have been effectively used to treat symptoms.
Active days. Keep moving with daily walks outside, even on cloudy days, and aerobic exercise. Both can help alleviate symptoms of SAD.
Winterize your mental health
Be proactive in safeguarding your mental wellness over the coming months. Most importantly, know the symptoms of SAD and call our office for help if you’re experiencing:
- Diminished interest in things that were once enjoyable
- Low energy or overwhelming fatigue
- Difficulty with concentration or focus
- Worthless or helpless feeling
- Sleep issues: too much sleep, or not enough
- Changes in appetite or weight; increases in carbohydrate and sugar cravings
Experts advise those who’ve previously experienced episodes of seasonal depression to try to get in front of it this year. Call our office for guidance regarding medications or CBT sessions. For many, reprogramming their mindset can help restore proper circadian rhythms and eliminate the psychological dread of winter. Try enrolling in an online class, taking up a new hobby or creating a new routine to optimize daylight exposure. Or keep it even simpler. As Dr. Rosenthal told the New York Times, “A 20-minute early morning walk in the sun can be as good as commercial light therapy.”
How to Replace Bad Habits with Healthy, Sustainable Behaviors
For entrepreneur physician Kyra Bobinet, MD, the typical reasons behind a failed diet served as the impetus for developing a novel approach to behavior change.
“I was doing so well. I knew what to eat, when to eat, how to eat, and then I just stopped doing it…and I don’t know why.”
Her answer to a patient’s familiar lament above, called the Iterative MindsetTM, is now used by the U.S. Centers for Disease Control and Prevention (CDC) to enhance its diabetes prevention program.
Drawing on her neuroscience and medical training at the UCSF School of Medicine and Harvard T.H. Chan School of Public Health, Bobinet conducted years of field research aimed at eliminating the inevitable gap between intention and action. What she discovered was a way to change even the most intractable bad habits and permanently replace them with healthy, sustainable ones.
The Iterative Mindset, Bobinet asserts, is the key to people who succeed despite seemingly insurmountable odds. In her early work helping frontline Walmart employees manage conditions such as obesity, cardiac disease and diabetes, she observed that only a small percentage of people were able to achieve the necessary lifestyle changes. Notably, they faced every possible headwind of financial and social stress – single parenting, senior caregiving, food insecurity and lack of healthcare access.
“Nonetheless, they somehow were able to lose weight, get off their medications, and dramatically improve their health,” she recounts. “We looked and looked, but the only common link between them was the Iterative Mindset, a resilient way of approaching behavior change like an experiment – with curiosity, innovation and no failure or blame if it doesn’t work out as planned.”
It’s a stark contrast with the way most people view their failure to change longstanding habits. Bobinet describes why: “The habenula, a recently characterized area of the thalamus, has two functions – detecting failure and then, if you think you failed, suppressing your motivation to keep trying. By activating whenever you believe you’ve failed to reach a goal, the habenula places you in a state of learned helplessness, associated with higher depression and low self-efficacy. This is when most people give up and bad choices ensue.”
She posits that those who form new habits by continually trying again in different ways, or iterating, are able to bypass that switch in the brain. An iterative mindset can succeed where the performance mindset, used for SMART (specific, measurable, achievable, relevant, time-based) goals or tracking steps with wearable devices, sometimes cannot.
“Performance mindset works well to motivate for tasks that are short-lived, and for optimization, such as athletes who have already experienced a substantial success and want to strive for the next level,” says Bobinet. “However, it can be detrimental when used to modify behaviors in more vulnerable people, setting them up for an eventual win or lose situation that triggers feelings of failure and causes loss of motivation to keep trying.”
True change only happens when a new behavior turns into a habit, repeated so frequently it grows to be automatic, and by definition becomes part of your lifestyle, says Bobinet. The process can take up to two years, with multiple relapses an expected part of the process.
“It’s completely natural to relapse when you’re stressed or distracted; it’s how fast you get back in motion that counts. And you cannot fail as long as you iterate,” emphasizes Bobinet. “Don’t blame yourself, blame what you tried—it wasn’t the right thing right now. Think of it as an experiment that needs tweaking and continue to version until you find the right fit for you.”

In the spirit of starting 2022 with healthy intention, we’ve taken a page from the U.S. Preventive Services Task Force (USPSTF) latest recommendations, long considered the gold standard for clinical preventive services, and prepared the following proactive guide to staying well in the new year.
Back in 1903, Thomas Edison predicted where we were headed: “The doctor of the future will give no medicine but will instruct his patient in the care of the human frame, in diet, and the cause and prevention of disease.”
While we have yet to reach the future envisioned by Edison, preventive care, relegated to the back seat during the pandemic, is in full gear once again.
Since 1984, the USPSTF team of volunteer, independent experts in internal medicine, family medicine, pediatrics, behavioral health, obstetrics/gynecology and nursing has conducted rigorous assessments of the scientific evidence for the effectiveness of a broad range of preventive screening, counseling and medications. Their findings, published in the Journal of the American Medical Association, laid the foundation for preventive medicine in primary care, from when to get your first colonoscopy to whether an aspirin a day is really the best way to keep a heart attack at bay.
A number of USPSTF recommendations have changed significantly over the years, guided by evolving science and clinical experience. In 2021, these changes included lowering the screening age for diabetes from age 40 to 35, lowering the age for colorectal cancer screening from age 50 to 45, and strongly discouraging people over 60 from taking a low-dose aspirin each day to prevent a first cardiovascular (CV) event. As recently noted by the advisory board, this doesn’t represent a flip-flop or misfire, but rather necessary updates based on new research. So, for example, when the latest evidence showed the increased risk of gastrointestinal or brain bleeds in certain populations from taking a daily aspirin to prevent CV disease, the panel reviewed, reconsidered and drafted a revision to its 2016 recommendation. Similarly, when data pointed to the incidence of diabetes increasing at age 35 and the benefits of lifestyle interventions for reducing progression from prediabetes to the more serious type 2, the USPSTF revised accordingly.
What’s on the radar for the USPSTF? Recommendations being studied now for potential updates include statin use for the prevention of CV disease; vitamin, mineral and multivitamin supplementation to prevent CV disease and cancer; behavioral counseling interventions for prevention of CV disease in low-risk adults; hormone therapy to prevent chronic conditions in postmenopausal women; effectiveness of screening for depression, eating disorders, obstructive sleep apnea, skin cancer, osteoporosis, glaucoma and atrial fibrillation; and a comparison of breast cancer screening methods. Stay tuned for new developments.
An Ounce of Prevention
Following are the latest USPSTF preventive medicine recommendations, intended for people without symptoms of the disease. As always, please consult with your healthcare provider for guidance based on your personal health situation.
