So THAT’S Why Mosquitoes Bite Some People More Than Others

Published

Here’s what makes you so attractive to the bugs and how you can prevent bites.

There are some biological reasons why mosquitoes are more attracted to some people more than others.

If you’ve ever been at an outdoor party or BBQ during the fading hours of daylight and don’t personally notice an increase in the number of mosquitoes, you’ll probably hear someone complaining about it. That’s because mosquitoes are selective insects, and some people are more likely to get bites than others.

There are a few factors that could contribute to why this happens: In one controlled study by the Journal of Medical Entomology, the bugs landed on people with blood Type O nearly twice as frequently as those with Type A. The researchers noted this has to do with secretions we produce, which tips mosquitoes off on a person’s blood type.

More research needs to be conducted on mosquitoes’ potential preference for certain blood types over others, said Jonathan F. Day, an entomology professor at the University of Florida. But he agreed that mosquitoes do pick up on some cues we give off that make the bugs more likely to land on certain people.

“These cues let them know they are going to a blood source,” Day said. “Perhaps CO2 is the most important. The amount of CO2 you produce, like people with high metabolic rates ― genetic, other factors ― increases the amount of carbon dioxide you give off. The more you give off, the more attractive you are to these arthropods.”

But what separates us from the nonliving entities that give off carbon dioxide, like cars? Mosquitoes look for primary cues in conjunction with what Day calls “secondary cues.”

Lactic acid — the stuff that causes our muscles to cramp during exercise — is one of those secondary cues, for example. Lactic acid is released through the skin, signaling to mosquitoes that we are a target, Day said…Click Here To Continue Reading>> …Click Here To Continue Reading>>

Mosquitoes also have other qualities that help them pick up on secondary cues.

“Mosquitoes have excellent vision, but they fly close to the ground to stay out of the wind,” Day said. “They are able to contrast you with the horizon, so how you’re dressed matters. If you have on dark clothes, you are going to attract more because you’ll stand out from the horizon, whereas those wearing light colors won’t as much.”

A mosquito also takes in “tactile cues” once it has landed on you.

“Body heat is a really important tactile cue,” Day said. “That comes into play with genetic differences or physiological differences. Some people tend to run a little warmer — when they land, they’re looking for a place where blood is close to the skin.” That means those whose temperatures are a little higher are more likely to get the bite.

Lifestyle or other health factors may also play a role, said Melissa Piliang, a dermatologist at Cleveland Clinic.

“If body temperature is higher, you’re exercising and moving around a lot, or if you’re drinking alcohol, you are more attractive to mosquitoes,” Piliang said. “Being pregnant or being overweight also increases metabolic rate.”

One study showed that people who consumed just one can of beer were more at risk of attracting mosquitoes than those who didn’t. Of course, drinking outside is a popular summer and fall activity.

“If you’ve been moving around all day doing yardwork and then you stop around dusk and drink a beer on your patio, you’re definitely at risk of bites,” Piliang said.

How To Prevent Mosquito Bites

Just because you might be more prone to bites doesn’t mean they have to be an inevitability. READ FULL STORY HERE>>>CLICK HERE TO CONTINUE READING>>>

“One of the very best things to do is to avoid peak activity times [for mosquitoes],” Day said. “There are very, very few species that are active in the middle of the day. They are very selective. Sunrise and sunset are when you’ll see peak activity.” Switching your early morning run to an after-work run could help here.

Of course, this tip won’t help you if you’re, say, throwing a BBQ for friends later at night. Try to cover as much skin as you can in these cases, Day said, especially in areas or at times mosquitoes are most likely to be present.

“I love the fishing shirts and the long-legged outdoor pants that are breathable, but they prevent mosquitoes,” Day said. “A repellent that has a good protection time ― defined as the time from when you apply to when you get the first bite ― is also great. Roughly 5% DEET sprays gives you 90 minutes of complete coverage.”

DEET is a common ingredient in insect repellents, and sprays with DEET are probably the way to go if you know you’re at risk of bites, Piliang said. Despite the controversy over the health effects of DEET, a 2014 review by the Environmental Protection Agency re-concluded that normal use of DEET products does not pose a risk to one’s health, including children, pregnant women and breastfeeding women.

“DEET is the most effective,” Piliang said. “If you are going to be in a mosquito-prone place, knowing that they carry disease, it is your best bet. Take a shower later to wash it off, and put on just a little bit.” Always read the directions on a spray before using it, and help children apply products by following the U.S. Centers for Disease Control and Prevention guidelines.

And while you may have heard that candles containing natural repellents like citronella oil can be useful, there is no research to support it yet. Instead, keep the fan on or hang out in a breezy area.

“Mosquitoes can’t get around very much,” especially in wind, Piliang said. “You can run a fan to keep air moving.”

If you do end up with a bite, you may or may not be bothered. “This all depends on how allergic you are to the chemicals in the saliva of the mosquito, and that can vary based on the type of the mosquito or how reactive you and your skin are to things in the environment,” Piliang said.

If it is itchy, the worst possible thing you can do is scratch it.

“If you do, then more histamine is released and it gets itchier,” she said. “If you scratch it, you’re also more likely to break skin. You can get bleeding, scabs and put yourself at risk for infection and scarring.”

But there are a few simple things you can do to alleviate the itch, like putting an ice cube on it. “The sensation of cold travels on the same nerve as itch, so you cannot feel both at the same time,” Piliang said. “Even a drink with ice on it will help relieve itch immediately.”

If you’ve received several bites after a morning or evening outside, she also recommended over-the-counter anti-itch creams with a mild topical steroid like hydrocortisone. “You can apply that two to three times a day to reduce itch,” she said.

“And the last thing you can do if you’re really bit up is take an antihistamine,” she added. “It can counteract the reaction a bit.” While OTC types that make you drowsy — like Benadryl — are more common, you can take non-drowsy antihistamines like Zyrtec or Allegra for daytime relief.

Of course, prevention is always better than treatment, so use these tips to stave off bites in the first place as you head out for the season’s remaining BBQs and tailgates.

If You Fall In Blood Group O, Avoid These Habits And You Will Live Longer

Published

on

By

Living longer and healthier often involves understanding how our genetic predispositions, including blood type, can influence our health outcomes. For individuals with blood type O, there are specific habits and lifestyle choices that, when avoided, can contribute to a longer and healthier life.

Blood type O is often referred to as the “hunter” blood type in the context of the blood type diet theory, which suggests that individuals with this blood type may benefit from a diet that resembles that of early humans who were primarily hunters and gatherers. While the scientific evidence supporting the blood type diet is limited and controversial, there are other health considerations that individuals with blood type O should keep in mind…Click Here To Continue Reading>> …Click Here To Continue Reading>>

 

One of the most crucial factors for individuals with blood type O is maintaining a balanced diet. While specific diet plans may vary, it is generally recommended to avoid processed foods, particularly those high in sugars and unhealthy fats. Instead, focusing on a diet rich in lean proteins, fruits, and vegetables can help support overall health and well-being. This dietary approach not only aligns with potential benefits suggested by the blood type diet but also with broader nutritional guidelines for promoting longevity.

Another important consideration for individuals with blood type O is regular physical activity. Engaging in regular exercise not only helps maintain a healthy weight but also promotes cardiovascular health, strengthens bones and muscles, and improves overall mood and mental well-being. Activities such as brisk walking, jogging, swimming, or participating in sports can all contribute to a longer and healthier life.

In addition to diet and exercise, managing stress levels is essential for individuals with blood type O. High-stress levels can contribute to a range of health problems, including hypertension, digestive issues, and impaired immune function. Techniques such as mindfulness meditation, yoga, or spending time in nature can help reduce stress and promote relaxation. READ FULL STORY HERE>>>CLICK HERE TO CONTINUE READING>>> READ FULL STORY HERE>>>CLICK HERE TO CONTINUE READING>>>

Furthermore, individuals with blood type O should be mindful of their caffeine and alcohol intake. While moderate consumption of coffee or tea may have some health benefits, excessive caffeine intake can lead to insomnia, anxiety, and digestive problems. Similarly, excessive alcohol consumption can increase the risk of liver disease, cardiovascular problems, and certain types of cancer.

Lastly, avoiding smoking and maintaining regular health check-ups are crucial habits for individuals with blood type O. Smoking significantly increases the risk of various diseases, including lung cancer and cardiovascular disease. Regular health check-ups allow for early detection and management of potential health issues, helping to maintain overall health and longevity.

In conclusion, while genetics and blood type play a role in health outcomes, lifestyle choices such as diet, exercise, stress management, and avoiding harmful habits like smoking and excessive alcohol consumption are crucial for individuals with blood type O to live longer and healthier lives. By adopting these habits, individuals can optimize their health and well-being, regardless of their blood type, and potentially increase their lifespan.

If You Don’t Want To Suffer Stroke At Old Age, Avoid Excess Intake Of These 3 Things

Published

on

By

As we age, the risk of suffering a stroke increases, but many of the factors contributing to stroke are modifiable through lifestyle choices, particularly diet. While no single factor guarantees a stroke-free life, reducing the intake of certain substances can help mitigate the risk significantly. Among the key culprits that contribute to stroke risk are excessive consumption of salt, sugar, and unhealthy fats. Here’s how these three substances affect stroke risk and why you should consider limiting them:

1. Excessive Salt (Sodium):

High sodium intake is one of the leading contributors to hypertension, which is a major risk factor for stroke. When you consume too much salt, it can cause your blood pressure to rise, putting extra strain on the heart and blood vessels. Over time, this can lead to damage to the arteries, making them more prone to blockages, which can trigger a stroke. The World Health Organization (WHO) recommends limiting salt intake to less than 5 grams per day. However, many people consume much more, primarily from processed foods, canned soups, fast food, and restaurant meals, where sodium is often hidden in excess. By reducing salt intake and choosing low-sodium alternatives, you can significantly lower your chances of developing high blood pressure and, by extension, stroke…Click Here To Continue Reading>> …Click Here To Continue Reading>>

 

 

2. Excessive Sugar (Added Sugars):

A diet high in refined sugars can contribute to the development of several conditions that increase stroke risk, including obesity, diabetes, and high blood pressure. Consuming too much sugar causes an increase in blood glucose levels, leading to insulin resistance, weight gain, and inflammation—all of which are linked to an elevated risk of stroke. Additionally, high blood sugar can damage blood vessels over time, leading to atherosclerosis, or the hardening and narrowing of the arteries. To protect your brain health, it’s important to limit sugary foods and beverages, especially sodas, candies, and baked goods, which contain added sugars that can cause rapid spikes in blood sugar. The American Heart Association recommends no more than 6 teaspoons (25 grams) of added sugar per day for women and 9 teaspoons (38 grams) for men.

3. Unhealthy Fats (Trans and Saturated Fats):

Not all fats are created equal, and while some fats are essential for good health, unhealthy fats—particularly trans fats and excess saturated fats—can increase your risk of stroke. Trans fats, often found in processed and packaged foods like baked goods, snacks, and margarine, can raise bad cholesterol (LDL) levels and lower good cholesterol (HDL). This leads to plaque buildup in the arteries, a condition known as atherosclerosis, which significantly increases the likelihood of a stroke. Similarly, a diet high in saturated fats, commonly found in fatty cuts of meat, full-fat dairy products, and certain oils (like palm and coconut oil), can also elevate LDL cholesterol and promote the narrowing of arteries. Replacing these unhealthy fats with healthy fats—such as those found in nuts, seeds, avocados, and olive oil—can help protect against strokes.

Final Thoughts: While there is no magic bullet to prevent a stroke, maintaining a balanced, nutritious diet is one of the most effective strategies for lowering stroke risk in older age. Reducing your intake of excess salt, sugar, and unhealthy fats can help regulate blood pressure, prevent plaque buildup, and maintain healthy blood vessels, all of which reduce the risk of stroke. Along with a healthy diet, regular physical activity, not smoking, and managing stress are also critical components of a stroke-prevention plan. By making conscious choices to limit these three substances in your diet, you can significantly improve your long-term health and reduce your chances of experiencing a stroke in old age.

In most situations, the first HIV symptoms show up 2–4 weeks after a person is exposed to the virus, but in certain circumstances, they might take months or even years to manifest.

HIV is the name of the virus that causes the illness of the same name. AIDS, a lethal disease brought on by a person’s immune system being significantly weakened, is its last stage.

Blood, breast milk, and sexual fluids are all ways that HIV can transmit. According to research, 94% of HIV infections in 2015 were caused by sexual contact…Click Here To Continue Reading>> …Click Here To Continue Reading>>

 

initial signs of HIV

HIV infection does not always result in immediate symptoms. It takes between two and four weeks for HIV symptoms to manifest.

Sometimes symptoms won’t show up for months or even years.

Timeline

HIV is categorized by doctors into three stages.

Acute HIV infection in Stage 1

A person with HIV exhibits specific symptoms when they are first infected. READ FULL STORY HERE>>>CLICK HERE TO CONTINUE READING>>>

Fatigue, muscle aches, rashes, headaches, sore throats, enlarged lymph nodes, joint discomfort, night sweats, and diarrhea are some of the symptoms.

A credible source claims that some of these symptoms are more likely to materialize than others. The likelihood of each of the symptoms is mentioned above in decreasing order.

HIV infection in stage 2 is ongoing.

The following are signs of a chronic HIV infection, according to certain studies, says a dependable source: yeast infection in the vagina and oral hairy leukoplakia, which results in white, scaly areas on the tongue. Possible diagnoses include shingles, neuropathy, cervical dysplasia, and the blood clotting condition idiopathic thrombocytopenic purpura.

The person’s immune system will suffer considerably if this stage continues. Their body will have a harder time fighting off infections and other illnesses as a result.

3.AIDS in Stage

AIDS manifests when a person’s CD4 cell count is significantly decreased as a result of HIV infection.

White blood cells called T cells, sometimes referred to as CD4 cells, are one type. They serve as the body’s defense against harmful microorganisms. These cells become dysfunctional as a result of HIV infection.
