Do you know your blood pressure numbers? Dr. Michael Bloch explains how maintaining healthy numbers are important for good quality of life and increasing longevity. High blood pressure, or hypertension, affects 85 million Americans – that’s one in three people. Left untreated, it can lead to serious and sometimes life-threatening health concerns such as vision loss, kidney disease, heart failure, heart attack and stroke. But what is it, exactly, what makes it go up and why is that increase in pressure so dangerous? All About Blood Pressure In order to function properly, your body requires a continual supply of oxygen rich blood, which is goes to organs and tissues via blood vessels called arteries. Your beating heart produces the force (or pressure) your vessels require to move blood. This is your blood pressure. Your blood pressure numbers reflect two forces at work – the pressure created as blood is pumped throughout the body (systolic) and the pressure when your heart is at rest in between beats (diastolic). A normal, healthy reading shows a systolic level at 120 or below over a diastolic level of 80 or less: 120/80. An increase in pressure occurs slowly over time, straining the circulatory system and forcing the heart, blood vessels and tissues to work harder. This friction damages blood vessel walls and lets plaque buildup from LDL cholesterol, setting the stage for hardening of the arteries. As more and more plaque builds up, your blood vessels narrow, further raising blood pressure, damaging the circulatory system and increasing your risk of serious health conditions. The Silent Killer High blood pressure is known as a “silent killer,” as most people with it have no symptoms. In fact, one in six of those affected don’t even know they have the condition. That’s why it’s so important to know your numbers. The only way to find out if you have high blood pressure is to have it measured, either by a health professional or using a home monitor. If your numbers are high, there are things you can do to help lower it – it is treatable, but not curable. You can manage it with medications and lifestyle changes including: Adhering to the Mediterranean diet Decreasing sodium intake Avoiding excessive alcohol consumption Increasing exercise and activity levels Losing weight Prevention and Genetics Even better? High blood pressure doesn’t just happen. You can prevent the condition altogether. How? Know your numbers and know your risk. Look at your family medical history. Genetics certainly increases the risk of it, but those same lifestyle choices that can improve poor blood pressure can also prevent you from developing it. So if your numbers are good, keep them that way – eat well, move your body, maintain a healthy weight and drink alcohol in moderation.

Since the COVID-19 pandemic, more people are working from home than ever before, leading to a rise in digital screen time. Between spending eight or more hours staring at a computer screen, and some downtime hours spent looking at a smartphone or watching TV, it’s almost inevitable to feel some adverse effects at the end of a day. Blue Light Effects vs. Digital Eye Strain Blue light is all around us, and the most natural source comes primarily from sunlight. Other forms of blue light are artificial and emitted by digital screens including LED TVs, smartphones, tablets and computers. Surprisingly enough, research shows blue light can actually have health benefits such as promoting alertness, boosting memory and cognitive function, elevating mood and regulating circadian rhythm. However, studies indicate that an excess in blue light exposure can lead to depletion of melatonin production, a hormone that regulates our sleep cycles. In today’s eyewear industry, blue light glasses are one of the more popular items purchased by consumers. Companies who sell the glasses claim they help with reducing or eliminating digital eye strain, while also increasing natural melatonin secretion to get a good night’s sleep. Other than their slight yellow tint to filter out blue light, they mostly look like regular glasses and come in many different stylish frames. You can find blue light glasses through various eyewear retailers. Most adults have experienced digital eye strain. Common symptoms of digital eye strain include headaches, blurred vision, irritated eyes, and fatigue. Many believe that digital eye strain is caused by overexposure to blue light, but medical vision experts say that is not the case. “Digital eye strain is related to how we use our digital devices, not the blue light coming out of them,” says Mitchell Strominger, MD, a neuro and pediatric ophthalmologist with Renown Health. Do Blue Light Glasses Even Work? Since blue light glasses aren’t medically proven to help with digital eye strain, you’re probably wondering if they’re even worth using. “If you’re one to binge a TV show or scroll though social media before bedtime, the blue light from those digital screens can disrupt your circadian rhythm and cause you to lose sleep, which can ultimately lead to other adverse health effects,” says Dr. Strominger. “While more research is still needed, some studies have shown that blue light glasses may prevent melatonin suppression and increase quality of sleep. There is no harm in trying them out and seeing if they work for you.” As for preventing digital eye strain, Dr. Strominger shared several helpful tips: Try using the 20-20-20 rule, which entails looking away from your screen and looking at an object 20 feet away for at least 20 seconds. Sit at an arm’s length (about 25 inches) away from your screen. Adjust the brightness and contrast of your screen, especially before bedtime. There is a night mode setting on most smart phones you can use. Reduce your screen time whenever you can and give your eyes a break.

You might think worsening eyesight is inevitable as you age. But the truth is, there are easy things you can do to keep your eyes in tiptop shape for years to come. Clear vision is an essential part of overall health and there are daily habits we can adopt to keep our eyes seeing clearly. Mitchell Strominger, M.D., a registered ophthalmologist with Renown Health specializing in pediatric ophthalmology and neuro-ophthalmology, offers some everyday tips to keep you focused on eye health. Know your family’s vision history Look to your parents and grandparents for clues about the future of your eye health. Were they near-sighted at a young age? Do they have a history of eye crossing or a lazy eye? Did they develop glaucoma or macular degeneration (AMD)? Some genes have a strong association with eye health, specifically macular degeneration. AMD is a leading cause of blindness worldwide and the top cause of vision loss and blindness for Americans over 65, according to the Centers for Disease Control and Prevention (CDC). Also be aware certain medical conditions, such as diabetes, high blood pressure and liver disease, increase the risk of long-term eye problems. Receive regular vision screening exams Children under three need vision screening examinations by their pediatrician. A medical concern or family history warrants a comprehensive eye examination by a pediatric ophthalmologist (or general ophthalmologist or optometrist who has experience with children) per the American Academy of Ophthalmology (AAO). Vision screenings should occur every two years throughout adolescence unless pain, eye crossing, difficulty seeing the board or reading, or other eye concerns occur. In adulthood the risk of eye problems increases over age 40, so the AAO recommends regular dilated exams. When your pupils are dilated it allows your eye care professional a more accurate view of your retina and optic nerve, located in the back of your eye. This allows them to look for AMD or other eye problems. Eye diseases can be caught at their earliest stages during a dilated eye exam. “It is especially important to have your child evaluated as soon as possible if there is any concern for eye crossing or lazy eye,” says Dr. Strominger. “The visual system develops in the early years so intervention, whether it be glasses, eye patching to strengthen the vision in one eye, or eye muscle surgery is critical. Children at risk include those who are born premature, have development abnormalities, genetic disorders such as Downs syndrome, or a strong family history and should be evaluated at a young age. Often small problems are not clearly evident and cannot be picked up on routine screening examinations in the pediatrician’s office.” Block the sun, improve your vision Everyone knows not to stare directly into the sun, but indirect ultraviolet (UV) sun rays can cause serious harm over time. According to the National Eye Institute, sunglasses (or a protective UV tint) are a daily must to protect your eyes from: Cataracts (a clouding of the eye’s lens causing blurred vision) AMD - macular degeneration Pterygium (a tissue growth over the white surface of the eye that can cause astigmatism) Look for sunglasses which block 99 to 100 percent of both UVA and UVB rays. You still need sunglasses if your contact lenses block UV rays. Sun rays can damage your eyelids and other tissue not covered by contact lenses. Wearing sunglasses protects your entire eye area. Eat colorful meals Your eyes need vital nutrients to keep them healthy including vitamin C, zinc, beta carotene and copper. A diet filled with citrus fruits and a variety of vegetables provide these essential nutrients. Regularly filling up on fish high in omega-3 fatty acids (salmon, tuna, sardines) may reduce your risk of AMD and help maintain your eye health. Green, leafy vegetables (kale, spinach, collard greens) containing lutein and zeaxanthin are also a must for your dinner plate. Water your eyes Eyes, like the rest of your body, need plenty of water to prevent dehydration. Make sure you stay hydrated and steer clear of smoke to avoid dry eyes and irritation. Hours staring at the computer screen can also make your eyes feel dry or tired. Try regularly refreshing them with lubricating eye drops. Taking frequent computer breaks is also important. Follow the 20/20/20 rule: every 20 minutes, look at an object 20 feet away from you for 20 seconds. Eye makeup can also lead to dry eye as the glands at the base of the eyelashes may become clogged, causing dry eye. Make sure all eye makeup is hypoallergenic and is thoroughly removed with a gentle cleanser for the delicate eye area each day. Stop Smoking (or never start) Smoking is harmful to every part of your body, including your eyes. It's not only linked to cancer and heart disease but also cataracts, AMD, dry eye, optic nerve problems and many other problems. Smoking during pregnancy can also harm the eyes of the unborn child. If you currently smoke take steps to quit and your entire body will benefit.

There are some important numbers to know when it comes to good health. Learn more and receive a free blood pressure check at a primary care open house Feb. 27 at Renown Medical Group – Double R. Know Your Numbers Adults are pretty good at knowing and memorizing numbers — from passwords and PINs to addresses and phone numbers. But what about the numbers that could help save your life? Heart disease remains the leading cause of death in the U.S., with 633,842 deaths attributed to the disease in 2016, according to the National Center for Health Statistics. The American Heart Association lists the vital numbers you need to monitor to help prevent heart disease as blood pressure, total cholesterol, blood sugar and body mass index (BMI). With these numbers, your doctor can assess your risk of developing heart issues such as atherosclerosis, which can lead to other serious heart conditions. Atherosclerosis is a condition wherein plaque builds up in the arteries — the blood vessels that transport oxygen-rich blood to cells, the heart and other organs. These fatty deposits clog the arteries, inhibiting blood flow and reducing the amount of much-needed oxygen the body receives. These blockages can lead to angina, coronary heart disease, peripheral artery disease and even heart attack or stroke. But knowing your numbers and keeping them in healthy ranges can mitigate your risk of atherosclerosis and other heart conditions. First things first: Make an appointment with your healthcare provider to see how you’re doing. Learn your numbers and discuss how they may increase your personal risk of heart disease: Total Cholesterol Because cholesterol contributes to the buildup of plaque, keeping your numbers in check means keeping your arteries free of blockages. Check LDL (bad) cholesterol and HDL (good) cholesterol. Your body needs low levels of LDL, but not enough good cholesterol in your system can also increase risk. You can maintain healthy numbers by staying physically active and consuming a heart-healthy diet low in cholesterol and sodium. Statins, the class of drugs used to reduce LDL cholesterol, have proven so effective that the U.S. Preventive Service Task Force recommended in November that all adults older than 40 with one or more risk factors consider taking them. Blood Pressure High blood pressure places undue strain on your heart and arteries to move blood and oxygen throughout the body. And a heart that’s working too hard can lead to stroke, heart attack and heart failure. High blood pressure cannot be cured, but it can be managed by eating a heart-healthy diet low in alcohol, staying active and maintaining a healthy weight. Blood sugar Given that the body converts most of the food we eat into glucose, or blood sugar, for energy, adding sugar to the diet can raise blood sugar to unhealthy levels and damage the heart, increasing risk of cardiovascular disease and obesity. Opt for foods that are low in fat and added sugars and, instead, get your sweets in naturally occurring foods. Let added sugars be a treat and not the norm. Body Mass Index (BMI) Your BMI is used to determine whether you’re at a healthy weight. If you’re carrying extra pounds, the heart has to work harder, which increases risk of heart disease. Losing those pounds and maintaining a healthy weight reduces the burden on your heart and blood vessels and improves your blood pressure and cholesterol levels. So eat a heart-healthy diet and get active — even if you simply walk for 30 minutes a day. Because no symptoms indicate that you have poor cholesterol numbers, high blood pressure or high blood sugar levels, getting screened and learning your numbers is vital. Your doctor can determine what healthy levels look like for you individually and work with you to develop a plan for staying in optimum ranges. That plan will include heart-healthy eating, exercise, abstaining from smoking and, in some cases, medication. It’s up to you to stick with that plan between doctor visits. Do it for yourself, but consider making a pact for a more heart-healthy, active life with a buddy. Research shows people stick with exercise plans longer when they have a partner.
