Have you ever experienced one of those annoying headaches that's right behind your eyes, and it makes it even more difficult to concentrate or even keep your eyes open? You dismiss it, think of it as stress or getting too much screen time—but what if it's something more? Headaches related to eyes are a real thing, and they tend to go unnoticed until they begin affecting your daily activities. Whether you're always on your computer, missing eye exams, or simply believe it's "normal" to reach for a pain reliever and tough it out, this tale is your reminder to pause and pay attention to what your body—and even more specifically, your eyes—are trying to say.

Headaches are a common experience—unwelcome, usually inconvenient, and usually dismissed as the aftermath of a long day or hectic schedule but when that headache targets the back of your eyes and starts disrupting your daily routine, it's time to listen more intently. That is not tension alone it may be your body communicating something more.

For health professionals, especially ophthalmologists, chronic headaches that focus around or behind the eyes can be more than mere stress. They can be indicative of latent ocular or neurological conditions that require professional intervention. To learn when a headache can be more than just about stress—and when it's time to seek medical attention—we spoke with Dr. Neeraj Sanduja, an eye surgeon and ophthalmologist.

Link Between Your Headaches and Eyes

The eyes are intricate, high-performance organs which are used continuously—whether reading, driving, or working on computer screens. When they're being worked too hard or strained from underlying problems, they tend to express discomfort as headaches. These would usually be known as ocular headaches, and in contrast to those caused by stress, they can be accompanied with characteristic signs like eye pain, pressure, redness, or visual changes.

Dr Neeraj says, "The eyes are complex organs that work tirelessly throughout the day. When they are strained or affected by underlying conditions, the resulting discomfort can manifest as headaches. These headaches are often referred to as ocular headaches and can have specific characteristics that differentiate them from other types."

Curiously, pain felt in or around the eye isn't necessarily from the eye. Most of these are "referred pain"—a condition in which pain is felt in one location but is caused by another. This is why it is so easy to miss the actual cause, particularly when visual symptoms are minimal or none at all.

Signs Your Headache Isn't Just Stress

While stress is sure to produce headaches, the following indicators could mean that your headache stems from an eye condition or some other health problem:

1. Frequent or Daily Headaches Behind the Eyes

If you’re waking up with headaches or experiencing them routinely at the end of your workday, eye strain may be playing a central role. This is especially common in people with undiagnosed vision issues or those who stare at screens for extended hours.

2. Blurred or Fluctuating Vision

Headaches with associated changes in your ability to see clearly may point to issues like astigmatism or imbalance of the eye muscles. Such vision inconsistencies make the eyes work harder, resulting in pain that is referred to the temples or brow.

3. Eye Pain Without Redness or Obvious Irritation

If your eye appears to be fine but you still have pain in deep or rear parts of your eye, it might be connected to neurological or inflammatory disorders like optic neuritis. This necessitates urgent professional attention to eliminate pressure buildup or other severe conditions.

4. Glare, Halos, or Nausea

Conditions like glaucoma may raise intraocular pressure, leading to severe headaches and sensations like halos around lights, vomiting, or extreme eye pain. These are warning signs of the utmost concern that need immediate attention.

5. Difficulty with Focus and Coordination

A less familiar condition known as binocular vision dysfunction happens when the eyes are slightly out of alignment. This causes eye muscles to overwork, causing headaches, dizziness, and problems concentrating. Even slight misalignments can drastically affect your quality of life.

Dr Neeraj shares a list of causes which could indicate more than just a simple headache, indicating towards a serious problem at times.

Common Eye-Related Causes of Headaches

Eye Strain (Asthenopia): Prolonged activities like reading, using digital screens, or driving can strain the eye muscles. This strain often leads to a dull ache around the eyes or temples.

Uncorrected Vision Problems: Conditions such as nearsightedness (myopia), farsightedness (hyperopia), or astigmatism can cause the eyes to work harder to focus. This extra effort may result in headaches, especially after activities that require sustained focus.

Incorrect or Outdated Prescription Glasses: Wearing glasses or contact lenses with an incorrect prescription can strain the eyes, leading to headaches. Regular eye checkups are crucial to ensure your prescription is up to date.

Computer Vision Syndrome (Digital Eye Strain): Spending long hours in front of screens without adequate breaks can cause headaches due to digital eye strain. Symptoms may also include dry eyes, blurred vision, and neck pain.

Glaucoma: This condition increases intraocular pressure and can cause intense headaches, often around the eyes. Headaches due to glaucoma may be accompanied by symptoms like nausea, vomiting, or halos around lights.

Eye Muscle Imbalance: Misalignment of the eyes, even if minor, can lead to strain as the muscles work harder to maintain focus. This condition, known as binocular vision dysfunction, can cause frequent headaches.

Inflammatory Eye Conditions: Conditions like uveitis or optic neuritis (inflammation of the optic nerve) may cause severe headaches along with other symptoms such as vision changes or eye redness.

When to Seek Professional Help?

Dr Neeraj recommends, "If you experience headaches frequently and suspect they might be related to your eyes, it’s important to consult an ophthalmologist." If you’ve tried lifestyle adjustments, hydration, and stress management, and your headaches still persist, it’s time to look beyond the usual suspects. Consider seeking medical attention if:

- The headache is persistent or worsening.

- The headache is accompanied by blurry vision, eye pain, or redness.

- There are additional symptoms such as nausea, sensitivity to light, or difficulty focusing.

- You haven’t had a comprehensive eye examination in over a year.

Even if your symptoms appear to be under control, getting checked out early can avoid complications and reveal underlying conditions that could otherwise go undetected.

Diagnosis and Treatment for Eye-Related Headache

When you go to see an ophthalmologist for headaches, the test normally involves a complete determination of your visual acuity, intraocular pressure, and assessment of the optic nerves. Often, the issue might not be in the eye itself but how the eyes work together or how external usage such as screen time is affecting their health.

Depending on the diagnosis, your treatment could include:

• Corrected vision eyeglasses or contact lenses, updated.
• Lifestyle changes such as the 20-20-20 rule: look 20 feet away every 20 minutes for 20 seconds.
• Surgery or even medication for more severe conditions like glaucoma.
• Vision exercises or therapy for binocular vision dysfunction.

Prevention and Long-Term Eye Care

To avoid eye-related headaches, begin with routine eye exams—even if you don't wear glasses. When working extensively on computers or other digital devices, keep your work area well-lit, employ blue light filters, and take regular visual breaks. Drinking water and stress management will also contribute to overall eye and brain health.

It's also worth mentioning that kids and adolescents increasingly are also coming in with similar symptoms, particularly with our screen-dominated life. So, parents are to stay vigilant about behavioral signs such as irritability, squinting, or complaints of eye strain in younger generations.

All headaches are not equal. If yours center around or behind the eyes, or if they come with visual problems as a bonus, don't attribute them to stress without a probe. Your eyes may be sending a message your body can't ignore.

Each year, hundreds of people around the world lose their lives waiting for a life-saving organ transplant. The demand for organs far outweighs the supply, leaving many patients with little hope. But what if we could print organs—tailor-made for each patient—using their own cells? While we're not quite there yet, researchers are making significant strides in this futuristic field known as 3d bioprinting.

Though the technology is still far from clinical trials, scientists believe that when 3d-printed organs become a medical reality, the process will likely involve a blend of cutting-edge imaging, personalised cell harvesting, and highly advanced bioprinting methods. Here's what this groundbreaking process could look like.

Step 1: Creating a Personalised 3D Model

To print a functional organ, the process begins with creating a precise 3D blueprint. While generic models can serve as a starting point, personalisation is key. Using imaging technologies like MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans, medical professionals can generate a detailed digital model of the organ tailored specifically to the patient’s anatomy. This personalized design enhances the chances of a successful transplant by ensuring the printed organ will fit and function properly in the recipient’s body.

Step 2: Collecting Patient’s Cells And Preparing Bioink

One of the biggest hurdles in organ transplantation is rejection, which happens when the recipient’s immune system attacks the new organ. To reduce this risk, scientists aim to use the patient’s own cells to build the organ. These cells are harvested, cultivated in labs, and combined with a specially designed “bioink”—a gel-like substance engineered to mimic the structure of natural tissues. This bioink becomes the medium through which living cells can be precisely layered and formed into complex biological structures.

Step 3: Printing the Organ

With a personalized 3D model in hand and a supply of bioink rich in the patient’s cells, the actual printing process begins. The organ is built layer by layer, using bioprinters designed to handle delicate biological material. Some methods involve extrusion-based bioprinting, which pushes the bioink through a nozzle to form a structure, similar to how icing is piped onto a cake. Other techniques rely on light-based bioprinting, which uses beams of light to shape the biomaterial with incredible precision.

In some cases, additional cells may be added to the organ after printing to support its development or enhance functionality. Although the exact tools and materials are still being refined, technologies such as the BIO X, BIO X6, and LUMEN X are among those helping to push the boundaries of what’s possible in tissue engineering.

Road Ahead

While researchers are still navigating numerous scientific and ethical challenges, the vision of printing fully functional, transplantable organs is no longer science fiction. With continued innovation and global collaboration, 3D bioprinting could one day eliminate organ shortages altogether, saving countless lives and revolutionizing modern medicine.

In a world where superfoods, supplements, and scientific advances define the health discourse, María Antonia Cuero's story shines for its elegant simplicity. At 123, María is officially the world's oldest living human—informally surpassing the Guinness World Record holder, France's Jeanne Louise Calment, who reached 122 years of age. Though her age remains in process of verification, the insights she offers are incontrovertibly priceless and scientifically validated.

Born on October 18, 1901, in Colombia, María has witnessed two world wars, numerous technological revolutions, and the dawn of modern medicine. Yet when asked what the secret to her remarkable longevity is, María doesn't refer to a magic pill or a genetic mutation. Rather, she attributes her longevity to two humble foods: fish and bananas—cornerstones of her daily diet, steeped in her coastal upbringing.

Growing up in a big family of 10 siblings by the Mayorquín River, María spent her days surrounded by nature. With fresh fish and tropical fruits readily available, her childhood diet was both organic and full of nutrients—years before these words became health buzzwords. Throughout the decades, she also raised eight children and is now the proud matriarch to 26 grandchildren, 24 great-grandchildren, and 54 great-great-grandchildren.

Although not officially documented by the Guinness World Records, María's identification card in 2012 indicates her birth as October 1901. She became the oldest to get vaccinated in March 2021, at 119 years old, marking yet another incredible achievement to her name.

However, aside from age and figures, it is María's way of living and attitude that provide deep insights into longevity.

Maria's Mindset and Philosophy of Longevity

In an interview on the Colombian television show Los Informantes, María discussed her philosophy of life: laugh frequently, don't worry excessively, remain active, and don't sit around too much. In her opinion, physical activity is essential. Her regimen included walking often, swimming, rowing, and being outdoors—long before fitness monitors or gym memberships were the rage.

These principles echo research in contemporary gerontology. Many studies identify an active life and good social relationships with a lower risk of chronic disease and longer lifespan. María's case supports that emotional well-being, combined with activity, is significant in healthy aging.

Fish

Of all the foods that she ate, fish is what María puts so much stress on. Living next to the river as a child, not only was she afforded the fresh catches each day, but she fished herself very frequently. "Good fish. I would fry the fish and then mix it with coconut and rice," she shared with a journalist.

Fish is a good source of high-quality protein, omega-3 fatty acids, vitamins D and B2 (riboflavin), and minerals like calcium, phosphorus, iron, zinc, iodine, magnesium, and potassium. Omega-3s in oily fish, particularly docosahexaenoic acid (DHA), are recognized to lower inflammation, maintain brain health, and decrease the risk of heart disease.

Scientific studies in the Journal of the American Medical Association have indicated that individuals with high levels of omega-3s live as much as 2.5 years longer on average. Another significant study identified a 40% lower risk of coronary heart disease mortality in those who ate regularly from fish with high levels of omega-3s, a figure further supported by the British Heart Foundation.

Bananas

María's second pillar of diet? Bananas—the smaller, sweeter bocadillo bananas (also referred to as sugar bananas or lady finger bananas). These bite-sized fruits are not only tasty but are full of fiber, antioxidants, potassium, and vital vitamins.

Bananas have been valued for centuries for their digestive and cardiovascular benefits. They help to control blood pressure, balance body fluids, and repair muscle and nerve tissue—all highly beneficial for elderly populations. The tryptophan and vitamin B6 contained in bananas also assist with serotonin formation, the "feel-good" neurotransmitter that enhances emotional well-being.

For María, these bananas were an everyday treat. And as science indicates, eating bananas on a regular basis can help with heart health, boost mood, and assist with muscle recovery.

What We Can Learn From Her Habit?

María's remarkable life is not merely about what she ate—it's about the regularity with which she lived. Her life was based on balance: a modest diet, regular exercise, a positive attitude, and close family ties. To this day, she radiates resilience. When asked what she is afraid of, her answer was moving: "I am not afraid of anything anymore."

This lack of fear and deeply ingrained calmness may also have protective health benefits. Studies have linked chronic stress to increased inflammation and a heightened risk of age-related diseases. María’s philosophy—“don’t worry too much”—may offer more protection than we’ve previously realized.

As the world population ages, María Antonia Cuero's life is an eloquent reminder: the route to longevity may not come in the form of costly therapies, restrictive eating, or vigilant self-tracking. It may sometimes be found in age-old secrets—eat fresh, move frequently, laugh without restraint, and enjoy the little things.

As we wait for official verification of her record-setting age, her legacy already walks tall as an example of how simplicity, persistence, and culture can overcome and thrive. In a world filled with constantly changing health fads, María's legacy encourages us to stop for a moment and ask—what really counts when it comes to living a long, healthy life?

Microplastics—those invisible particles of plastic pollution—may be doing more than just contaminating the environment. According to recent findings presented at the American Heart Association (AHA), they could also be silently contributing to clogged arteries, potentially raising the risk of heart attacks and strokes.

In a study that’s turning heads in the medical community, researchers discovered that fatty plaques found in neck arteries—known as carotid arteries—contained over 50 times more microplastic content compared to plaque-free arteries. Even more concerning, these microplastic concentrations were found to be significantly higher in individuals who had already suffered from a stroke, mini-stroke, or temporary vision loss caused by restricted blood flow.

What Exactly Are Microplastics?

Microplastics are extremely small particles—often less than five millimeters in size—created when larger pieces of plastic break down. They can enter the human body in multiple ways: through the air we breathe, the food we eat, and even skin contact. An even smaller subset, known as nanoplastics, measures under 1,000 nanometers and is completely invisible to the naked eye. Because of their minuscule size, these particles can infiltrate tissues, organs, and potentially disrupt biological functions.

The accumulation of microplastics in arterial plaques introduces a new dimension to the ongoing conversation about cardiovascular risk factors. While high cholesterol, smoking, and hypertension remain the usual suspects, environmental pollutants like microplastics are emerging as a stealthy but significant threat.

A Simple Solution In Your Kitchen?

Amid growing concerns about microplastic contamination, especially in drinking water, scientists have been working on practical ways to mitigate exposure. In 2024, a research team from Guangzhou Medical Centre made a breakthrough. They discovered that a common household activity—boiling water—can significantly reduce microplastic content in tap water.

According to the team, combining boiling with basic filtration can remove up to 90% of nanoplastic and microplastic particles (NMPs) from household water. However, the method’s effectiveness varied depending on the type of water used. In areas where tap water contains higher mineral content, commonly referred to as "hard water," the technique proved especially efficient.

The secret lies in limescale. As hard water is heated, it forms limescale—a chalky white substance—which appears to create a sticky layer that traps microplastic fragments. Researchers found this natural process enhanced the removal of plastic particles from water, offering a practical and affordable solution for most households.

While more research is needed to fully understand the long-term health effects of microplastics, early evidence suggests they may be more dangerous than previously thought—especially for cardiovascular health. Taking simple precautions, such as boiling and filtering drinking water, could help reduce exposure and offer a small but meaningful step toward safeguarding your heart and overall well-being.
