Your blood type is often overlooked in everyday life, but it might hold clues to your cognitive health. Recent studies have shown an interesting links between specific blood types and the risk of cognitive decline, including dementia. Many people don’t even know what their blood type, if they do not get any bloodwork done or donate anything. Blood types are categorized based on specific proteins, or antigens, on the surface of red blood cells. For instance, people with type A blood have the A antigen and the B antibody in their plasma. The Rh factor, either positive or negative, further categorizes blood types. But can your blood type be an indication of any diseases or risks you have?

While your blood type doesn't significantly impact your daily life but it can influence your risk of developing certain health conditions. For example, people with type O blood are more likely to develop ulcers, while those with type A blood are more prone to heart disease.

Blood Type and Cognitive Health

A 2014 study published in the Neurology showed a link between blood type and cognitive decline. People with type AB blood seem to have an 82% higher risk of developing memory and thinking problems compared to those with type O blood. This may be due to higher levels of certain proteins in their blood that can affect blood clotting and inflammation. However, it's important to note that these are just associations, and more research is needed to fully understand the connection between blood type and cognitive decline.

Blood type is also related to other heart related conditions like stroke, so the findings highlight the connections between vascular issues and brain health. The study also identified higher levels of Factor VIII, a clotting protein linked to cognitive decline and dementia, in individuals with AB blood type.

What Corelation Does AB Blood Type Have With Brain Function?

Although the AB blood type is relatively rare in the United States, it doesn't automatically guarantee the development of dementia. While some studies have linked specific blood types to cognitive decline, others have yielded conflicting results. For example, a 2017 study in Medical Science Monitor suggested a higher risk of postoperative cognitive dysfunction, which means decline in your cognitive function after surgery, in older adults with type A blood.

On the other hand, a 2015 study in PLoS One that was done with 1.5 million participants, found no significant link between blood type and dementia. It also suggested that there is a lower risk for people over 70 with the type A blood compared to type O.

Other Factors To Consider

A 2022 meta-analysis in Neurology found that people with blood types A, B, and AB tend to have more proteins in their blood that can cause clotting compared to those with type O. These blood types are also linked to proteins that affect inflammation and blood vessel health. The ABO gene, which determines what blood type you will have, is also associated with proteins influencing inflammation and poor blood flow to the brain can lead to cognitive decline, this could explain why certain blood types might be associated with a higher risk of dementia.

While you can't change your blood type, you can take steps to protect your brain health. A healthy lifestyle, including a balanced diet, regular exercise, and managing stress, can significantly reduce your risk of cognitive decline, regardless of your blood type.

A balanced diet rich in fruits, vegetables, whole grains, and lean protein can help to protect your brain health. Regular exercise, such as walking, swimming, or biking, can also help to improve cognitive function.

If you are someone who suffers from dry and itchy eyes, a recent update may not be the best news for you. As per the enforcement report from the Food and Drug Administration (FDA), 75,000 cases of eye drop solution were voluntarily recalled nationwide by the BRS Analytical Service, which is a pharmaceutical testing lab.

Why Are These Products Recalled?

The recall came in the backdrop of FDA audit at BRS Analytical Service, which found a number of Current Good Manufacturing Practice (cGMP) deviations. These are a set of regulations enforced by the FDA to ensure that manufacturers use safe practices to produce pharmaceutical products, reports NBC news.

"cGMP deviations may lead to products of unacceptable quality, and it is not possible to rule out patient risks resulting from use of these products,” said AvKare, which is a manufacturer of medical, surgical, and pharmaceutical items, which had originally reported the recall.

Furthermore, as per the enforcement record, the recall is also "due to a lack of assurance to sterility". These products are also described as "eye lubricants", which help relieve dry and irritated eyes.

Which Products Have Been Recalled?

NBC news reports that the recall includes ophthalmic solutions shipped over a two year period from: May 26, 2023 until April 21, 2025, according to AvKare.

• NDC# 50268-043-15 Artificial Tears Ophthalmic Solution
• NDC# 50268-066-15 Carboxymethylcellulose Sodium Ophthalmic Gel 1%
• NDC# 50268-068-15 Carboxymethylcellulose Sodium Ophthalmic Solution
• NDC# 50268-126-15 Lubricant Eye Drops Solution
• NDC# 50268-678-15 Polyvinyl Alcohol Ophthalmic Solution

So, What Can You Do Instead?

Dr Anita Sethi, who is Principal Director and HOD Ophthalmology, Max Multi Specialty Centre at Panchsheel Park recommends to stay away from natural remedies like haldi (turmeric) or ginger from putting inside the eye.

In absence of eye lubricants, she recommends certain daily habits that can help protect the eyes from dryness. "In the extremely dry and hot weather, we need to protect our eyes by wearing sunglasses or caps and avoid the direct dust and wind going into the eyes when we are sitting in an air-conditioned room or the fan avoid the blast directly in your face, like when you're driving. Keep the vents so that it is away from your face and not going directly into the eyes."

When asked if there are anything one can eat to ensure their eyes are not dry, she said, "food and nutrients that help with dry eye basically just maintaining the health of the eye, which is foods rich in vitamin E, antioxidants. Coloured vegetables and fruits and even maintaining your thyroid and vitamin D levels because these also contributes to dry eye."

The key to ensure that your eyes are protected from environmental factors like sun, dust, and eat, especially for those who work outdoors or spend long hours on screen, she recommends investing in good sunglasses with ultraviolet protection.

"For those who are using computers a lot, you need to blink your eyes constantly, take breaks in between, and drink a lot of water. Dehydration is also contributing factor to dry eye." She also recommends using a zero number protective glasses and computer glasses that can decrease strain and dry eye.

When summer arrives and the air grows thick with warmth, it brings with it an unwelcome guest—mosquitoes. That irritating buzz in your ear, the sharp sting on your skin, and the maddening itch afterward can quickly turn a pleasant evening into a nightmare. But have you ever noticed that mosquitoes seem to swarm around you more than others? If you find yourself swatting away bites while your companions remain unbothered, you're not alone—and you're not imagining it.

Turns out, mosquitoes do play favorites, and science has a few fascinating explanations for why that might be. From your blood type to your wardrobe, your scent to your sweat, here’s a deep dive into the weird and wild biological reasons why mosquitoes might just love you more—and what you can do about it.

Before we decode their behavior, it’s important to understand the threat they pose. Mosquitoes are among the deadliest creatures on earth, not because of their bite itself, but because of what they can carry. From Dengue, Malaria, and Chikungunya to Zika Virus and Japanese Encephalitis, mosquitoes are silent vectors for disease that impact millions globally. According to the World Health Organization, mosquito-borne illnesses claim over a million lives each year—making them far more than a backyard pest.

Why Do Mosquitoes Bite?

Contrary to popular belief, mosquitoes don’t bite for food. Male mosquitoes survive entirely on nectar, while females seek out blood to obtain proteins vital for egg development. That’s right—only the females bite, and they do it for reproduction.

But mosquitoes don’t choose their targets randomly. Their decision to bite you is rooted in biology and chemistry. Female mosquitoes are equipped with a suite of sensory tools that allow them to detect carbon dioxide from nearly 160 feet away, identify specific skin odors, and even spot you based on the color of your clothes. Here are five weird biological reasons mosquitoes may find you more irresistible than others.

1. Your Blood Type

There’s long been speculation that mosquitoes prefer certain blood types, and science offers some support. A 2004 study found that mosquitoes landed on people with Type O blood nearly twice as often as those with Type A. A more recent 2019 study reinforced this finding, observing mosquitoes feeding more frequently from Type O blood samples.

While the exact mechanism isn’t fully understood, researchers believe it’s related to secretions on the skin associated with specific blood types—particularly in people known as “secretors,” whose blood type antigens are found not just in their blood but in their saliva, sweat, and skin.

2. The Color of Your Clothing

Mosquitoes are highly visual and rely on sight to locate hosts, especially in the daylight. Studies show that darker colors—black, navy, and red—stand out more to mosquitoes. These colors retain more heat and contrast strongly with green, natural environments, making you an easy target.

Light-colored, loose-fitting clothing offers more than just summer comfort—it can be your first line of mosquito defense.

3. You Emit More Carbon Dioxide

Every time you exhale, you release carbon dioxide, one of the key cues mosquitoes use to track humans. Larger individuals, people who are pregnant, or anyone who’s physically active emits more CO₂ and is more likely to attract attention.

According to research published in Chemical Senses, mosquitoes detect carbon dioxide using an organ called the maxillary palp, which enables them to lock in on their target from a shocking distance of up to 164 feet.

4. Your Body Odor

Human sweat contains a mix of compounds—like lactic acid, ammonia, and uric acid—that mosquitoes find irresistible. Newer research highlights the role of carboxylic acids, which are produced when beneficial skin bacteria break down sebum (the waxy substance secreted by your skin).

Interestingly, even the most expensive perfumes or colognes may not mask these natural odors. Genetics, hygiene, and lifestyle factors like exercise can all impact how your skin smells to a mosquito.

5. Alcohol

Yes, even your choice of beverage can make a difference. A small study found that mosquitoes were more likely to land on participants after they had consumed beer. While the sample size was small and the findings modest, it raises interesting questions about metabolism, body temperature, and skin chemistry post-consumption.

Why Some People Swell More Than Others After Bites?

Mosquito bites don’t affect everyone equally. Some people develop small red dots; others end up with itchy welts. The difference lies in your immune response. When a mosquito bites, it injects saliva that contains anticoagulants and proteins. Your immune system releases histamine to combat these foreign substances, which causes inflammation and itchiness. People with stronger immune responses tend to have more visible reactions.

Remedies To Protect Yourself

Forget citronella candles and unverified home remedies. The most effective repellents contain DEET, picaridin, or oil of lemon eucalyptus. For those preferring natural alternatives, plant-based repellents such as neem oil, lavender, and citronella can help, though they may need more frequent application.

Want an extra layer of protection? Look for sunscreens that also offer mosquito repellent features—perfect for beach days and hikes alike.

How to Make Your Home Mosquito-Free?

A few strategic changes can turn your home into a mosquito fortress:

• Eliminate stagnant water in pots, buckets, and bird baths—mosquitoes breed in still water.
• Use ceiling fans to disrupt mosquito flight patterns.
• Install window screens and keep doors shut during dawn and dusk.
• Add mosquito-repelling plants like marigold, basil, and lemongrass to your garden.
• Taking cues from global solutions like the Caribbean’s approach to community fogging and public awareness can also make a lasting impact.

Understanding why mosquitoes target you is more than a fun fact—it’s a survival skill. Armed with knowledge and the right protection, you can reclaim your summer without constantly itching or worrying about disease.

Cancer diagnoses is one of the most devastating news that one receives. The future after the revelation may seem bleak, but as many cancer survivors have said, one must power through and try their best. During these times, you lean on your close ones and friends for help, even if it is just for emotional support. Angela Torres always looked out for others, and helped them as best she could, until it was her who needed the help.

Angela is a busy mom with three kids and a full-time job. She also runs two food banks in the Bronx, New York City. She took over this important work from her mother, who also believed strongly in helping the community. However, when Angela found out she had breast cancer, it made her rethink everything about herself.

Angela said that before her diagnosis, she was always the one taking care of everyone else. She admitted, "I didn’t want anyone to think I was weak."

Finding a Lump and Diagnosing Cancer

At 39, Angela felt a small lump in her breast. Tests showed it was stage 0 breast cancer, also called carcinoma in situ. This meant it was very early, and she didn't need more treatment. This experience made Angela realize how important it was to get regular mammograms and checkups. She also encouraged her loved ones to do the same.

A few years later, Angela's sister had a mammogram, and doctors wanted to carry out more tests because they suspected something serious. The results, fortunately, showed no serious signs.

This scare made Angela's sister urge her to get another mammogram sooner than planned. Angela remembered, "She kept saying, ‘I just have a bad feeling.’ So I moved my mammogram appointment up six months, mostly just to get her to quit talking to me about it.”

Angela clearly remembers getting the call with the results of that mammogram. She was ironing her son's shirt for his prom the next day. Her doctor told her they had found several tumors that she would never have been able to feel on her own.

More Serious Diagnosis and a Change in Plans

Angela had another surgery to remove the tumors and take samples from her lymph nodes. Sadly, the tests showed that the tumors were cancerous. Doctors found different kinds of breast cancer cells. Most were hormone-positive, but one was triple-negative breast cancer (TNBC). Because TNBC can be more aggressive, Angela's treatment plan had to change. She would need surgery, chemotherapy (chemo), and radiation.

Treatment was a long and difficult process. After surgery, Angela had four months of chemo. Then, she had a few weeks to recover before starting daily radiation for several weeks. Her doctor explained that the side effects of chemo and radiation can build up over time. Angela wasn't sure what that meant for her life. But when she started radiation and experienced more side effects, she understood. Some of the side effects from chemo were still bothering her, and the radiation added to them.

How did Community Support Helped Her Prognosis?

Even though the treatment was hard, it worked. Angela believes that her positive attitude played a big part in getting through it. She also learned to accept help from others during her treatment. This was new for Angela, and she said it was the hardest thing to adjust to. "I just didn’t want to feel weak. I didn’t want people to give me that ‘awww’ look. I wanted to be superwoman and just power through, but you have to allow the help in," she explained.

American Cancer Society (ACS) explained that emotional support is crucial for better chances of survival during cancer. A strong emotional support helps people going through cancer have a more positive outlook, better changes in the cancer, and reports show that it helps them better their life quality immensely.

Small things like making brief calls, ending the call with ‘I’ll be in touch soon’, calling when it is suitable for them, returning their messages as soon as you can, checking in with their caretaker to know if they need anything.

True to her nature, Angela strives to help more people, she has spoken at events, at interviews, and with friends and family. Her goal is to use her experience to help save lives and talk about cancer honestly. She thanks ACS for their help and contribution, and gives people hope for the future and love “Nobody wants to go through this, but they make you feel like they're with you for the fight. That means everything.”
