If you feel like you’re the victim of itchy mosquito bites more often than others, it may not be all in your head.

Sonja Swiger, Ph.D., Texas A&M AgriLife Extension Service entomologist, professor in the Texas A&M College of Agriculture and Life Sciences Department of Entomology and self-proclaimed mosquito magnet from Stephenville, said there is some scientific evidence that mosquitoes have preferences for who to land and feed on.

Mosquitoes primarily rely on carbon dioxide to locate their targets, Swiger said. Body temperature and odor also play significant roles, so anything that alters these factors can make someone more or less attractive to mosquitoes.

To separate evidence from anecdotes, Swiger discussed some of the attributes or conditions that studies have shown to entice mosquitoes.

Blood type matters, sometimes

Several studies have shown mosquitoes prefer type O blood. One study published in the Journal of Medical Entomology found a mosquito species preferred to land on type O blood compared to others, but the difference was only significant between type O and type A.

Though it’s often reported that mosquitoes prefer type O blood, Swiger said it’s worth considering the limitations of these studies.

“Some projects have shown that there may be some correlation between blood type and mosquito preference, but in a comparative study, there’s always a winner,” she said. “That doesn’t necessarily mean it’s the absolute winner all the time.”

Some foods and alcohol

People who are intoxicated tend to put out more carbon dioxide and sweat more, which seems to attract mosquitoes — possibly along with other unknown factors.

Swiger said diet can also impact mosquito attraction, though the extent of its effect hasn’t been fully explored. Garlic and vitamin B are often anecdotally reported to deter these bugs, but the evidence is limited.

However, Swiger said bananas and other high-potassium foods have shown to attract mosquitoes, perhaps because they lead to an increase in lactic acid production in the body, which helps mosquitoes locate animals.

This also impacts a person’s skin microbiota, or the microorganisms living on the skin.

“There is some research to support that changing your diet will make you give off different scents,” Swiger said. “So, it may be possible to change your attractiveness to mosquitoes based on what you’re eating.”

Pregnancy attracts mosquitoes

Pregnant women also seem to attract more mosquitoes, primarily because of the increased carbon dioxide output. It’s estimated that women in the advanced stages of pregnancy exhale about a 21% greater volume than non-pregnant women.

Swiger said this goes along with other physiological changes, like increased body temperature, that together make pregnant women easier for mosquitoes to find.

A taste for the local flavor

Sometimes mosquitoes develop more specific tastes in a location over time as an evolutionary trait.

“Mosquitoes in certain neighborhoods can become accustomed to specific scents and start to prefer those over others,” Swiger said. “Their generations are about two weeks long, and urban mosquitoes that bite humans often don’t travel far. As a result, they seem to get familiar with the local scents.”

Other genetic predispositions

There’s still much to uncover as far as mosquito preferences. Swiger said there seems to be other genetic predispositions for what attracts mosquitoes, but these aren’t all clear just yet.

“If you find yourself swatting more mosquitoes than your friends, there is probably some science behind it,” she said. “While there’s no getting around genetic predispositions, staying covered and using repellant might just help you tip the scales in your favor.”

Keep cold and flu season at bay

Published

on

(Family Features) It doesn’t take much for cold and flu symptoms to take over. Even a mild case of the sniffles can make it difficult to navigate the demands of everyday life. It’s virtually impossible to avoid germs altogether, but you can make sure you’re ready to fight off an infection, whether it’s a minor cold or a full-blown case of the flu.

“I always share a few easy and simple methods with my patients when cold and flu season comes back around to keep them in the best shape,” said Dr. Tim Tiutan, board-certified internal medicine physician. “Not only does getting ahead offer protection, but knowing what to do when symptoms start to come on, and what to have in your medicine cabinet, can help ease the burden of an oncoming illness.”

Preparation and prevention play important roles before a bug hits, but it’s also valuable to know how to effectively treat an illness and keep your loved ones from getting sick.

Prevent
Short of stashing yourself away in a bubble, there aren’t many failsafe ways to fully avoid germs. However, some basic hygiene and preventive care can go a long way toward minimizing your risk. Regularly washing your hands can help get rid of germs before you accidentally introduce them to your eyes, mouth or nose. Be especially diligent after spending time in crowded places.

Maintaining an overall healthy lifestyle also helps ensure you’re in optimal condition if you do get sick. That means eating a nutritious, well-rounded diet and keeping up with your exercise routine. Also be sure to talk to your doctor or pharmacist about getting a flu shot; while it may not fully prevent you from getting sick, in most cases it helps your body fight back and keeps your symptoms manageable.

Prepare
Knowing you can’t completely eliminate your exposure to germs, it’s a good idea to ensure you have everything you need to fight a cold or flu on hand. At least once a year, give your medicine cabinet a thorough cleaning. Discard any expired medications and replace products that have run low, especially those designed to help fight symptoms like pain relievers, fever reducers, decongestants, antihistamines and cough syrups.

It’s also a good time to restock items like tissues, cough drops, hand sanitizer and antibacterial soap. Medical supplies like thermometers and humidifiers also come in handy when you’re under the weather; check to be sure yours are in good working order and consider adding any supplies you don’t already have, such as a blood pressure cuff or home oximeter.

Treat
Once you’re sick, sleep is one of the best remedies. Your body can redirect energy toward healing when you’re sleeping, which helps boost your immune system, so give yourself permission to rest when you’re feeling down.

In addition to getting enough rest, it’s important to treat your symptoms, not just mask them. Because symptoms like fever, runny nose, chest congestion, cough and more can indicate a more serious problem, finding the root cause of the symptoms can be a more effective treatment strategy.

For example, some common remedies for chest congestion only mask the symptoms. Many doctors recommend an option like Mucinex 12-Hour because it treats the cause of chest congestion by thinning and loosening excess mucus. One dose lasts up to 12 hours, helping you clear mucus and relieve chest congestion.

Contain
Getting rest and managing your symptoms are easier when you stay at home, but it’s also the best way to prevent spreading germs to others. It’s not always practical, but if you can, limit yourself to one area of the house, away from family members. Cough into your elbow or a tissue, never your hands. Use antibacterial hand sanitizer and wipe down surfaces to minimize others’ contact with your germs.

Be especially wary of spending time with anyone who has a compromised immune system while you’re contagious, including those with pre-existing conditions, older adults and pregnant women. Take advantage of delivery or curbside services for essentials like groceries and talk with your employer about working remotely or using sick time until you’re feeling better.

When to Call for Help if You’re Feeling Lousy

If you’re experiencing cold symptoms, you might wonder when it’s appropriate to see a doctor for further evaluation. While most colds resolve on their own within a week or two, there are certain instances when seeking medical attention is advisable.

High Fever: If your fever persists for more than three days or reaches 102 F or higher, consult a health care provider.

Persistent or Severe Headaches: If you experience persistent or severe headaches that are not alleviated by over-the-counter medication, it’s advisable to consult a health care provider, as this could indicate a more serious underlying issue.

Persistent Symptoms: If your symptoms worsen or don’t improve after a week, seek medical advice.

Unusual Symptoms: If you experience uncommon or concerning symptoms during a cold, such as extreme fatigue, confusion, dehydration or a high fever that doesn’t respond to treatment, consult your doctor promptly for a proper diagnosis and treatment plan.

Trouble Breathing: Difficulty breathing, chest pain or wheezing can indicate a more severe respiratory condition and warrant medical attention.

High-Risk Individuals: For individuals at high risk of complications from colds, such as pregnant women, the elderly or individuals with conditions like diabetes or heart disease, it’s important to seek advice early to prevent any potential complications.

Remember, your health care provider can offer guidance tailored to your specific situation, helping you manage your cold effectively and ensure optimal recovery.

Understanding the risks of uncontrolled LDL cholesterol

(Family Features) Millions of Americans are at risk for life-threatening cardiovascular events due to high cholesterol, a condition nearly everyone has heard of yet just a fraction fully understand. In fact, many don’t realize they have high levels of harmful cholesterol until they experience a heart attack or stroke.

According to the Centers for Disease Control and Prevention, 71 million adults in the United States have high low-density lipoprotein (LDL) cholesterol, also known as “bad” cholesterol. Of these, nearly 50 million Americans do not have LDL cholesterol levels under control and are at higher risk for cardiovascular events, such as heart attack and stroke.

Protecting yourself and your loved ones from the effects of high LDL cholesterol starts by arming yourself with key information.

What is High LDL Cholesterol?
“Your body needs cholesterol – a waxy, fat-like substance – to work properly,” said Stephen Pinkosky, PhD, vice president, drug discovery and early development at Esperion. “However, having too much LDL cholesterol can lead to blockages in your arteries. Often impacted by both lifestyle choices and genetics, it’s important to maintain an LDL cholesterol level recommended by your health care provider.”

What are the Risks of High LDL Cholesterol?
“It’s often not until there may be a large blockage of the artery that you notice something is wrong, such as chest pain, pain in the arms or jaw, nausea, sweating, shortness of breath or weakness,” Pinkosky said. “These symptoms can occur when blood supply to the heart or brain is being slowed or blocked.”

These blockages, which may not have previously caused symptoms, can rupture and cause major problems, including heart attack or stroke. According to the American Heart Association, the first sign of elevated LDL cholesterol may be a deadly cardiovascular event for some people.

According to the World Health Organization, elevated LDL cholesterol causes more deaths than all forms of cancer combined and accounts for around 1 in 3 deaths in the U.S. and Europe. The Centers for Disease Control and Prevention estimates heart disease deaths will increase 25% by 2030.

What Can People Do to Get Cholesterol in Check?
One of the best ways to take care of your health is to be proactive. Even if you’re feeling fine, it’s a good idea to get your LDL cholesterol levels checked and discuss the results with your health care provider to determine the best treatment option for you, if needed. Your care team will consider your LDL cholesterol level, along with any other factors that make a heart attack or need for a heart procedure more likely to occur, such as your age, sex, family history (genetics), presence of diabetes or high blood pressure and lifestyle (like whether or not you smoke and your diet).

For those with high LDL cholesterol, there are options to get your level under control. Studies show reducing LDL-C levels with certain cholesterol lowering medications may reduce the risk of major cardiovascular events.

Consult your health care provider if you are unsure of your LDL cholesterol level or want to discuss options to lower your level. To learn more about high LDL cholesterol risks and management, visit cardiosmart.org.

Essential tips to support your immune system

Published

on

(Family Features) The immune system – made up of organs, tissues, cells and proteins – is your body’s personal defense system against bacteria and viruses, helping ward off illness and infection. Because of the vital role it plays in keeping you healthy, it’s important to take steps to keep your immune system strong.

Consider these healthy habits that can go a long way toward supporting your immune system and maintaining your health.

Practice Proper Hygiene
Good hygiene – and avoiding close contact with people who are sick – is a key component of maintaining a healthy immune system. Practices such as washing your hands frequently with soap and water for at least 20 seconds; covering your nose and mouth with a tissue or your elbow when coughing or sneezing; and disinfecting oft-touched objects and surfaces like doorknobs, light switches, counters and remote controls can help remove germs and reduce their spread.

Consider a Nutrient-Rich Supplement
The body requires many essential nutrients to form the foundation of a healthy immune system. Consider adding a nutrient-rich supplement like Airborne, which has been reformulated with seven key essential nutrients – vitamins A, C, D and E; zinc; manganese; and selenium. Available in effervescent tablets and chewable gummies, with flavors varying from Zesty Orange to Very Berry and Citrus, the addition of vitamin D and increased levels of zinc mean the improved formula provides the most essential nutrients of any Airborne immune-supporting supplement.

Maintain a Healthy Diet
Because a poor diet can weaken the immune system, according to research published in “Science Direct,” giving your body the nutrients it needs is key to helping your immune system thrive. Including a variety of fruits and vegetables, which are rich in antioxidants and vitamins, as well as whole grains, lean proteins and healthy fats as part of your meals can help strengthen your immune system. Also remember to drink plenty of water to stay hydrated and limit processed foods, sugary snacks and beverages high in added sugars that can weaken your immune system and have a negative impact on your health.

Engage in Regular Physical Activity
Not only can maintaining a regular exercise routine help build muscle and improve endurance, it helps improve circulation, too, which allows immune cells to move more freely through the body. Aim for at least 150 minutes of moderate or 75 minutes of vigorous exercise per week, such as brisk walking, cycling, swimming or dancing. This activity also promotes the production of endorphins and can help reduce stress, further benefitting to your immune system, according to the Mayo Clinic. Just be sure not to push yourself too hard, as excessive exercise can have the opposite effect and put your body under more physical stress.

Get an Appropriate Amount of Sleep
Sleep and immune health are intertwined. In fact, inadequate or poor-quality sleep can lead to a higher susceptibility to illness, according to research by the Sleep Foundation. During sleep, your body repairs and rejuvenates itself, so aim for the expert-recommended 7-9 hours of quality sleep each night. Establish a regular sleep schedule by going to bed and waking at the same time each day, even on weekends, and create a relaxing routine to signal to your body it’s time to wind down. This may include limiting screen time an hour before bed, reading or practicing relaxation techniques. A comfortable, cool and dark sleep environment can also improve the quality of your sleep.

Manage Stress Levels
Stress, both physical and mental, can weaken your immune system and lead to a higher risk of infection, particularly if it leads to sleep disturbances, reduced water intake, less frequent exercise or unhealthy eating habits. To effectively manage stress, practice relaxation techniques such as meditation, yoga or deep breathing and prioritize self-care through activities you find relaxing like reading, listening to music, journaling, exercising or spending time outdoors.
