Cases Spiking in Some Southern Universities

 



By Ralph Ellis


September 1, 2020 – Coronavirus cases are climbing fast at the University of Alabama’s flagship campus in Tuscaloosa, with more than 1,200 students and 166 faculty and staff testing positive for COVID-19, according to the university system’s COVID-19 dashboard.


That’s a big jump from about a week ago, when around 600 students and five faculty-staff members had tested positive. The school normally has about 33,000 students.


The university is sticking with in-person classes so far, but is limiting campus gatherings. Some on-campus housing has been cleared out for students who’ve tested positive, and about 36% of that isolation space is occupied, the dashboard said.


In an attempt to keep students from congregating downtown, Tuscaloosa Mayor Walt Maddox issued an executive order to close bars from Aug. 24 to Sept. 8.


Those numbers from last week alarmed the university administration, with school President Stuart Bell saying Aug. 24 that, "The rise we've seen in recent days is unacceptable, and if unchecked, threatens our ability to complete the rest of the semester on campus. Now is the time for action."


In other news about education and the coronavirus:


The University of South Carolina is warning students who violate coronavirus restrictions by holding parties and ignoring quarantines.


The school sent letters to students saying they could be suspended or expelled for breaking the rules, the Post & Courier in Charleston reported.


“We are very serious about that,” USC President Bob Caslen said during a virtual town hall. “We ask students to take responsibility.”


The school’s COVID-19 dashboard says 620 students and 14 school employees have tested positive since Aug. 1. The case count has risen sharply in the last week.


Georgia Tech reported that new cases on campus doubled in a week, according to WSB-TV.


By Saturday, the school was reporting 641 confirmed cases since March, twice the number from 7 days ago. The school coronavirus dashboard said that as of Sunday, 705 cases had been reported, with 64 new cases reported on Sunday.


The school locked down Sigma Phi Epsilon fraternity house after dozens of members tested positive for coronavirus, the fraternity announced on Instagram.

Cardio Exercises Good for More than Just Your Heart

 



Heart Health Is Just the Start

You probably already know that cardio, or "aerobic," exercise -- the kind that gets your heart pumping -- is good for your ticker. It lowers your resting pulse and strengthens your heart muscle. That's why, as you slowly lengthen your cardio workouts, you're able to go for longer time and distance. But your heart isn't the only part of your body that benefits.


Lower Your Blood Sugar

Cardio exercise helps lower blood sugar (glucose) levels and improve insulin resistance if you have diabetes. Resistance training, like weightlifting, is also good. A combination of the two seems to help the most. Talk to your doctor before you start a new fitness routine if you have diabetes, especially if you take insulin or other meds.


Improve Your Mood

Aerobic exercise like running can help ease depression and anxiety well enough that your doctor or therapist may suggest it as a treatment. Part of the reason might be that it seems to enlarge your hippocampus -- an area of your brain that manages emotion -- and slow the breakdown of brain cells. Stick with it on a regular basis for several months to get the most benefit.


Get a Better Night's Sleep

Cardio may be good for your shut-eye. Scientists know that it can help you keep an even mood, wind down at bedtime, and set up a healthy sleep-wake cycle (circadian rhythm). The exact brain effects aren't always clear, but people who exercise more tend to get more of the deep "slow wave" sleep that helps renew the brain and body. But try not to exercise too close to bedtime, which disrupts sleep for some people.


Think Better

People who do more aerobic exercise may be better at "executive function" -- the ability to organize information, interpret it, and act on it. Just a single workout session can increase blood flow to the part of your brain called the prefrontal cortex, which helps control your executive function. Over the long term, exercise seems to help brain cells in your prefrontal cortex connect more easily.


Remember Better

People who move around more are less likely to get Alzheimer's disease and other forms of dementia. That's in part because exercise helps prevent things that can raise your chances of getting dementia, such as obesity, diabetes, high blood pressure, and depression.


Learn Better

Neuroplasticity is the ability of your brain to change when you learn and do new things. Younger brains are generally better at this than older ones, but you can help preserve your neuroplasticity with cardio exercise, along with resistance training. 


Help Ease Arthritis Pain

As you age, your knees and other joints can get osteoarthritis. The movement of aerobic exercise, like jogging or biking, is one of the most effective ways to ease pain and inflammation. And whether you walk, swim, or row a boat, your heart gets fitter, which makes it easier to stay active. When you combine physical activity with a healthy diet, you can drop extra pounds, which takes pressure off your knees.


Breathe Better

Even if you have a lung condition, regular cardio exercise can help improve your breathing. If the gym's not your thing, a walk, jog, or a regular tennis game can do the trick. Just make sure to talk to your doctor about your exercise plan if you already have breathing problems. 


Help Fight Germs

Regular aerobic exercise appears to help your body fight illness caused by viruses and bacteria. That's partly because it helps blood get around your body better, which means germ-fighting substances get where they need to go. Scientists continue to study exactly how exercise helps boost the immune system -- your body's defense against germs.


Improve Your Cholesterol

Exercise seems to raise your HDL "good" cholesterol. It can also lower your LDL "bad" cholesterol, though you may need to make your workout more intense to get the full effect. Unhealthy cholesterol numbers make you more likely to build up plaque in your arteries that can lead to a heart attack or stroke. Talk to your doctor about starting a fitness routine if you're already ill or you haven't exercised in a while.


How Much Exercise Is Right?

Standard recommendations call for 30 minutes of moderate exercise on most days of the week. That's a great place to start. But upping that to 300 minutes a week or higher can add even more benefits. The length of each session matters, too. Some of the best brain benefits come in exercise periods that last a bit longer: 45 to 60 minutes.

Can You Get Covid from Sharing Food & Drinks?

 


By Elizabeth Hanes, BSN, RNAugust 26, 2020


One of the joys of eating at a restaurant (outdoors, of course) is sharing an appetizer with your dining partner. But should you? Can you get COVID-19 from sharing food (or drinks)?


Ordering a large, bubbling dish of artichoke dip may sound appealing, but even if nobody “double-dips,” you should avoid it. Because, yes, you might be able to get COVID-19 from sharing food and drinks.


Lots of germs – including the virus that causes COVID-19 – can be present in saliva, so if an infected person bites into that chip and then dips it into the creamy artichoke concoction, they definitely introduce bacteria and viruses into the dip for everyone to share. Gross!


What if you don’t double-dip? Can you still get COVID-19 from sharing an appetizer if everyone behaves in a civilized fashion?


Theoretically, merely breathing onto the dip (or salsa or…any food whatsoever) could transfer viruses and bacteria to the food. So, it’s possible you could transmit the coronavirus that way, but it’s not likely.


By the way, you also shouldn’t sip from somebody else’s straw or from their beverage. An infected person can deposit the coronavirus on the end of a straw or the lip of a glass – or you could possibly slurp up germs in the beverage itself. Also, don’t rely on any alcohol in your wine or cocktail to kill germs that make their way into the drink. To destroy bacteria and viruses, the liquor would have to be at least 60% alcohol by volume (ABV), which is far stronger than red wine (around 12% ABV) or even vodka (usually about 40% ABV).


Bottom line? To stay safe from COVID-19, skip the sharable appetizers, don’t share bites of food off your plate, and don’t sip from someone else’s beverage.

Better Skin After 50

 



Get Glowing Skin Now

Your wisdom and confidence may grow as you get older, but the same isn't true for many of your hormone levels. During menopause, lower levels of estrogen have a big impact on your skin. Less estrogen makes you prone to thinning, sagging, and wrinkling. Fortunately, you can relieve some of the skin-related effects of aging by taking care of your specific skin care needs.

Your Skin and Menopause

Menopause causes many changes to your skin. Your body stops making as much collagen. You lose some fat under your skin and your skin's elasticity drops. That, combined with dryness caused by hormonal changes, can cause sagging -- especially around the neck, jawline, and cheeks -- and fine lines and wrinkles. The lines and wrinkles you get with menopause are often crow's feet and lines above the upper lip.

Clean Up!

Cleansing is an important skin care step -- especially as you age. As you get older and your skin gets drier, your skin especially can benefit from extra moisture. The key is using a cleanser that's right for drier skin. So, opt for a creamy formula that hydrates instead of foam or gel cleansers, which can strip moisture away.

Hydrate, Hydrate, Hydrate

After menopause, your skin gets drier because oil glands aren't as active. Try to give skin more moisture with a heavier cream. Skip long, hot showers and put on moisturizer while your skin is still damp. That helps boost hydration.

You Still Need SPF

Even though skin cancer and wrinkling are caused by the amount of sun you got in your 20s, 30s, and 40s, you still need to protect your skin. Why? Skin may have less natural protection than when you were younger. So look for a broad-spectrum SPF of 30 or higher, and wear it every day.

Minimize Wrinkled Skin

You get wrinkles from too much sun damage over the years, as well as the hormonal changes of menopause. As your hormone levels decrease with age, that can change your skin quality and make wrinkles worse.   Wrinkles may be more obvious when your skin is dry, especially as you age. Use moisturizer on your face, jawline and neck every day, and look for skin care products designed to help fight fine lines and sagging and that lead to a brighter appearance overall.

Hit the Spots

Age spots on the face, hands, and chest can look more obvious around menopause. Help prevent them by using sunscreen every day. Already got spots? Fade them with exfoliating products that shed dead skin cells, which can be dull and flaky. Skin-lightening products can help fade spots. Toners can also help even out skin color.

Help Your Hands

The backs of your hands can lose moisture, collagen, and fat during menopause. That can make veins more obvious and skin more wrinkled. Plus, your skin can look see-through and bony. To reduce the look of wrinkles, use moisturizer often on your hands. Protect them from the sun.   And wear gloves when doing house or yard work.

Eat Your Antioxidants

Collagen gives your skin its youthful plumpness and keeps your skin tight. As your estrogen levels drop, so does the collagen in your skin. Eating foods with antioxidants may help make your skin stronger from the inside out. Look for brightly colored fruits and vegetables (they get their color from these healthy compounds) and try to eat every color of the spectrum.

Stock Up on Soy

Soy is rich in isoflavones, plant-based compounds that seem to act like estrogen in the body. Isoflavones may help improve age-related changes like thinning skin. Experts believe about 50 mg of isoflavones -- that's like like 3 ounces of tempeh or a half cup of miso -- a day can help menopausal women in other ways, too.

Look for Balance

Stress can make your skin drier and more sensitive. It can also trigger conditions like psoriasis. And if you're stressed out, you might even forget your skin care routine. Try yoga, meditation, and other stress-reduction techniques to help you relax.

Work It Out

Exercise does more than just tone your muscles. It helps skin in two ways. First, it relieves stress. Exercise also boosts circulation, which begins to slow with age. The extra oxygen and blood flow can help your skin look brighter and healthier.

Bulk Up on Beauty Sleep

Getting enough sleep helps your skin look fresh. Sleep can help prevent dark circles under your eyes, and it also gives the rest of your body a chance to recharge. Lack of sleep can change your hormone levels and metabolism in many of the same ways that aging does. So shoot for a solid 7 to 9 hours of shut-eye every night.

Best & Worst Foods for Belly Fat

 



Belly fat is worse for you than fat elsewhere on your body.

Excess accumulation of belly fat is more dangerous than excess fat around your hips and thighs. Belly fat is associated with serious health problems, such as heart disease, stroke, and type 2 diabetes. Your genes can contribute to your being overweight and help determine where you carry this extra fat, but poor lifestyle choices are likely to worsen the issue.

Fatty foods, such as butter, cheese, and fatty meats, are the biggest cause of belly fat.

Eating high-fat foods is not helpful, but excess calories of any kind can increase your waistline and contribute to belly fat. Still, there is no single cause of belly fat. Genetics, diet, age, and lifestyle can all play a role. Changing dietary habits can help you fight the battle of the bulge and fight belly fat: Read labels, reduce saturated fats, increase the amount of fruits and veggies you eat, and control and reduce your portions.

Calories from alcohol are worse for belly fat than other calories.

Excess calories -- whether from alcohol, sweetened beverages, or over-sized portions of food -- can increase belly fat. Our bodies need calories, yet gram for gram, alcohol has almost as many calories as fat.

Alcohol does seem to have a particular association with an increased waistline, though. In general, that’s because when you drink alcohol, your liver is too busy burning off alcohol to burn off fat, leaving you with a beer belly. Studies show that alcohol can cause you to feel hungry by affecting hormones that regulate a sense of satiety.

Which of the following fats not only can make you gain weight, but also can move fat from other parts of your body to your belly?

Researchers at Wake Forest University found that trans fats, which are created by partially hydrogenated oil, increase the amount of fat around the belly and redistribute fat tissue to the abdomen from other parts of the body. Trans fats may be found in such foods as margarine, pastries, cookies, crackers, and fried and convenience foods.

Which of the following shows promise for fighting belly fat?

Green tea, in combination with exercise, could help you lose weight, according to the Journal of Nutrition. Researchers think substances in green tea known as catechins stimulate the body to burn calories and enhance loss of belly fat. Blueberries also show promise, at least in rodents. In one study, rats bred to become obese were fed either a high-fat diet or a low-fat diet rich in blueberries. Rats fed a blueberry-rich diet had less abdominal fat.

Fast food can contribute to belly fat because the items are often:

Many fast-food options are typically high-fat, calorie-dense foods that are eaten in large portions -- all of which contribute to over-consumption of calories, weight gain, and an increase in belly fat when eaten frequently. Many fast-food restaurants don’t provide nutritional information, but studies have shown that when this is available, people tend to pick lower-calorie meals.

Substituting diet soft drinks for regular soft drinks is a good way to trim belly fat.

According to the American Heart Association, “soft drinks and other sugar-sweetened beverages are the No. 1 source of added sugars in the American diet.” Added sugars mean added calories -- something you want to avoid to help with weight loss and cut down on belly fat. Yet, high-fructose corn syrup has gradually replaced refined sugar as the main sweetener in soft drinks and has been blamed as a potential contributor to the obesity epidemic.

  Does switching to diet sodas help? Although some research has suggested that people who drink artificially sweetened sodas as part of a calorie-restricted diet do lose weight, other studies have suggested that diet soft drinks could even lead to weight gain. 

To help trim your waistline, you should eat a diet high in fiber.

To trim your waistline, add whole grains to your diet. For example, choose brown or wild rice instead of white rice. Refined and other highly processed foods can contribute to weight gain and interfere with weight loss.  A study in the American Journal of Clinical Nutrition showed that a calorie-controlled diet rich in whole grains can trim extra fat from the waistline of obese subjects.

Studies suggest you can trim your waistline by replacing refined grains with whole grains. Which of the following is a whole-grain food?

Couscous, spaghetti, and cornflakes are made from refined grains (though whole-grain options may be available). But popcorn is a whole-grain food that can boost fiber. The best way to prepare popcorn is with an air-popper, which requires no oil for cooking. Read labels to see what oils have been added to microwave popcorn.

All else being equal, whole grains are better than refined grains because they tend to be high in fiber and take longer to digest. This satisfies your hunger better and helps lower blood glucose levels and reduce fat.

Men tend to collect more belly fat than women.

Overall, men tend to store fat in the abdominal area more than women do, thanks to sex hormone differences. Before age 40, women tend to store most of their fat in the hips, thighs, and buttocks. After 40, as estrogen levels drop, body fat is redistributed to the abdomen.

Belly fat is harder to lose than fat elsewhere on your body.

When you lose weight, you’re much more likely to lose it in your midsection. Losing weight on a well-balanced plan will melt body fat, including belly fat. The best way to decrease your waist size is through healthy eating and regular exercise.

Spot exercises, such as sit-ups or crunches, target belly fat.

Doing sit-ups, crunches, or other abdominal exercises will strengthen your core muscles and help you lose fat, but they don’t specifically work on belly fat. In other words, spot exercise won’t decrease belly fat. The only way to lose belly fat (or any kind of fat) is through dieting and exercise. Aerobic exercises, such as running, swimming, cycling, and tennis, are some of the best to help reduce body fat.

Belly fat has been linked to which of the following health problems:

Belly fat appears to be especially bad for the heart. Studies have linked belly fat to heart failure, atherosclerosis, and other cardiovascular problems. It also has been associated with osteoporosis, dementia, Alzheimer's disease, diabetes, colorectal cancer, metabolic syndrome, high blood pressure, and other health problems.

Which of the following is the best plan for reducing belly fat?

Most scientific evidence suggests that a calorie-controlled diet rich in fruits, vegetables, whole grains, low-fat dairy, beans, nuts, seeds, lean meat, fish, eggs, and poultry is the foundation for a diet that provides all the nutrients you need while helping to whittle your waistline. Weight loss experts recommend combining this diet with 30 to 60 minutes of exercise most days of the week.

A Guide to Heart Failure

 



What Is Heart Failure?

The name doesn’t mean your heart stops. It just doesn’t work as well as it should. It happens when the heart can’t pump enough blood and oxygen to your body. It may be because the heart muscle has been weakened. But there are also other things that may cause the heart to work less efficiently than  it should. The heart can compensate for a while, but eventually you'll need to get treated.

What Causes It?

Your heart can begin to fail as you age, but the condition can affect young people, too. Most people with it had a related problem first. It could be high blood pressure, coronary artery disease, a heart attack, a birth defect of the heart, or a disease that strikes the blood-pumping muscle. 

Lung disease can lead to heart failure, too. Obesity, diabetes and sleep apnea have also been linked to it.

Symptom: Shortness of Breath

It's one of the first red flags you may notice, especially after you’re active. It can also happen when you’re at rest once heart failure gets worse. Sometimes you may feel short of breath when you’re lying down or sleeping. That’s because the heart can’t keep up with the blood flow back to it from the lungs. When that happens, fluid leaks into the lungs. That will make it harder to breathe.

Symptom: Fatigue

If your heart isn’t pumping properly, the brain takes blood from less-important areas of the body -- like the muscles in your limbs -- to the brain and other vital organs. That can make your arms and legs feel weak. You may feel tired doing everyday things like climbing stairs or walking across the room. You can also get light-headed.

Symptom: Nagging Cough and Wheeze

This is another sign that your heart is struggling, and that blood returning to it from the lungs is backing up. That means fluid gets in your lungs. Sometimes, the cough can bring up white or pinkish mucus. Let your doctor know if you have it.

Symptom: Swelling and Weight Gain

Fluid can back up in tissues, too. This can cause your feet, ankles, legs or belly to swell. The kidneys, since they have less blood to work with, may not get rid of sodium as well. That would cause more fluid to stay in your tissues. Talk with your doctor right away if you have persistent swelling or sudden weight gain.

Symptom: Nausea

You may have that -- or you might just feel full, as if you can’t eat any more. Either way, that can lead to a lack of appetite. This happens because your digestive system isn’t getting enough blood and oxygen.

Symptom: A Racing Heart

It's a common warning sign. When your heart doesn’t pump enough blood, your body knows. It can make up for this in a few ways:

  • By adding muscle to your heart to push more strongly

  • By enlarging your heart so it can stretch and snap back better

  • By making your heart beat faster

Symptom: Confusion

You may seem confused or sluggish. You might be disoriented, or you might start forgetting things. When other organs aren’t working well because of a lack of blood, it affects the amount of some things (like sodium) in the blood. This can affect your brain.

Tips to Prevent Heart Failure

You can lower your odds of getting the condition. Make sure to eat well and exercise. If you smoke, quit. If you’re carrying a few extra pounds, do what you can to lose them. If you’re already at high risk, or your heart already is damaged, your doctor can help lower your risk with medicine. It’s important that you and your doctor work as a team.

Heart Failure Treatment

There’s usually no cure for the problem, but it can be treated. Typically, that plan will include things like exercise and a low-sodium diet. Your doctor may ask that you weigh yourself daily to make sure you’re not keeping too much fluid. You’ll also need to keep track of how much fluid you eat or drink each day. There’ll be medicine to take. You’ll also likely need to manage stress and avoid caffeine. Your doctor might also recommend surgery to implant devices to help your heart, too.

Living With Heart Failure

It doesn’t have to rule your life. Focus on what you can do with your condition, not what you can’t do. You may have to choose what’s most important and skip some of the other things. You may have to rest up, too.

9 Tips for Better Posture

 



Don't Be a Slouch


It adds to the stress on your spine. That puts a strain on the bones, muscles, and joints you need to hold your backbone in place. But lousy posture isn't just bad for your back. A constant slump smashes your inside organs together, and makes it harder for your lungs and intestines to work. Over time, that’ll make it hard to digest food or get enough air when you breathe.


Straighten Up


A great way to prevent posture problems? Stand up tall. You'll feel better and look better -- slimmer, even. Pretend you’re standing against a wall to measure your height. Hold your head straight and tuck in your chin. Your ears should be over the middle of your shoulders. Stand with your shoulders back, knees straight, and belly tucked in. Don't let your booty or hips stick out. Straighten up so you feel like your head stretches toward the sky.


Don't Slump at Your Desk


It's comfy to slouch -- maybe even lean back and swivel a bit. But it’s a posture no-no. Try this instead: Sit all the way back in your chair. Place a small, rolled-up towel or lumbar cushion behind your mid-back to protect your spine's natural curve. Bend your knees at a right angle and keep them the same height, or a bit higher, than your hips. Place your feet flat on the floor.


Beware of 'Text Neck'


On your smartphone all day long? Take a minute to stretch your neck. When you tilt your head down to check messages it really strains your spine. Over the course of a day -- or year -- that can add up. For a better view, lift the phone up and move your eyes, not your head.


Don't Be a Low-Rider


Sure, it's cool and comfy to recline during a long drive. But it isn’t great for your posture. Instead, pull your seat close to the steering wheel. Try not to lock your legs. Bend your knees slightly. They should be at hip level or a tad above. Don't forget to put a pillow or rolled-up towel behind you for support.


Save Heels for a Big Night Out


They might be a fashion yes, but they’re likely a posture no. Pumps and stilettos thrust the base of your spine forward, which over-arches your back. That can change the way your backbone lines up and put pressure on nerves, which causes back pain. Sky-high shoes also put more weight on your knees. Choose a lower, chunky heel for daily wear.


Hit the Hay the Right Way


Naptime is no excuse to slack. Skip the soft, saggy mattress. Choose a firm one that helps hold your spine's natural shape. Side sleeper? Bend your knees slightly but don't hug them. Place a pillow under your head so it's level with your spine. Back sleepers should ditch the thick pillow and opt for a small one under the neck.


Exercise and Tone Your Abs


Too many pounds around your belly puts added stress on your back. You need strong muscles to support your spine. A well-designed workout plan will keep your body and spine in tip-top shape. And that's important. Try non-impact exercises like tai chi.


Check for Problems


You probably know if you slouch or not. If you aren’t sure, here's a quick way to tell. Place the back of your head against a wall. Move your feet 6 inches out from the baseboard. Your tush should touch the wall. Your lower back and your neck should be about 2 inches from it. If not, talk to your doctor about ways to improve your posture.
