Getting sunlight and vitamin D does a lot of good to human body. Many people express how they often feel low and unwell when they are confined in close quarters for a long time and the best example for this is the Covid-19 pandemic, this is all because they lack vitamin D. But an unexpected condition that may benefit from vitamin D is psoriasis.

Psoriasis is an autoimmune disease that causes dry and itchy patches on your skin. A study published in the Medicine suggests that if you don't have enough vitamin D, your body's defense system might act up, which could make psoriasis worse. Vitamin D is really important for keeping your bones strong and your body's defenses working well. It might also help your skin stay healthy. Scientists are looking into whether getting more vitamin D can help people who have psoriasis feel better.

Another study published by Skin Pharmacology Physiology suggests that vitamin D is very important for our skin. It controls how skin cells grow, mature, and die, and it keeps your skin's protective barrier strong. It also helps your skin's immune system. If you don't have enough vitamin D, you're more likely to get skin problems like psoriasis and eczema.

How Vitamin D Affect Skin Health?

Some people with psoriasis have low levels of vitamin D. This could be because they try to stay out of the sun, which is how your body makes vitamin D. It's also possible that having low vitamin D can make your body's defenses go into overdrive, leading to psoriasis. Vitamin D also affects skin cells called keratinocytes, and if you don't have enough vitamin D, these cells might grow too fast, causing the thick, scaly skin that psoriasis is known for.

Vitamin Deficiency: Who Is At Risk?

People with psoriasis often have low vitamin D levels, but it's not always clear why. It could be because they don't eat enough vitamin D-rich foods, don't get enough sunlight, or have certain health problems. Older people, people who are overweight, babies, and people with dark skin are more likely to have low vitamin D. If you think you might have low vitamin D, your doctor can do a blood test to check. Taking too much vitamin D can be harmful. It can cause you to lose your appetite, pee too much, have heart problems, and have too much calcium in your blood, which can lead to kidney stones. Always talk to your doctor before taking vitamin D supplements.

Right now, there's not a lot of proof that other vitamins or supplements can help with psoriasis. Some people believe that taking fish oil, which has omega-3 fatty acids, might help because it can reduce swelling. But there haven't been enough big studies to show if it really works. It's always best to talk to your doctor before trying any new vitamins or supplements for psoriasis

Many people believe that being diagnosed with cognitive degenerative diseases like Alzheimer's is just about forgetting things. However, it is not that simple. The Alzheimer's diagnosis comes with not just lost memories, but also changes in the way you think, the way you behave as well as losing the memories and important factors of your life.

One of the most devastating facts about these cognitive diseases is the difficulty in diagnosing them early. There has been a lot of research done on how to identify early signs and symptoms of diseases like Alzheimer's; however, their accuracy is still under scrutiny.

A recent research showed that a simple blood test can accurately spot early signs of Alzheimer's disease. Experts have found that these blood tests can reliably find dementia by looking at two specific proteins in the blood.

New Blood Test for Alzheimer's

Scientists are excited about a new blood test that can really well find early signs of Alzheimer's disease. This test looks for two proteins, amyloid beta 42/40 and p-tau217. These proteins are linked to sticky clumps that build up in the brains of people with Alzheimer's. The test is very good at finding people with memory problems, with a 95% success rate. This means it hardly ever missed a case. It also correctly said that people did not have dementia 82% of the time. This amazing new test has even been approved by the Food and Drug Administration (FDA) in the US.

Why This Test Is Important

The number of people getting dementia is expected to go up a lot. Because of this, it's really important to find out if someone has it quickly and correctly. Scientists say this new blood test works just as well as the harder and more uncomfortable tests used now. It's also much easier and cheaper. Levels of the p-tau217 protein were much higher in people with Alzheimer's. Next, they will test it on even more people, including those who might have early Alzheimer's but don't show any memory problems yet.

Experts think this blood test will make finding Alzheimer's much faster, easier, and available to more people. While it mainly helps with Alzheimer's, the test was also used on people with other types of dementia. This suggests it could help figure out what's causing memory problems.

Pushing for Blood Tests in the NHS

There's a big project called the Blood Biomarker Challenge. It's supported by large charities and aims to bring blood tests for dementia diagnosis to the NHS by 2029. These tests are seen as super important for making diagnoses quicker. This will give more people faster access to the care, support, and treatments they really need. Investing in these new tests and the staff to use them is key, especially as new treatments for dementia are coming soon.

What's Next for Diagnosis

This new study adds to more and more proof that blood tests can find the diseases that cause dementia, even in people with early memory issues. But, we still need more research to see how well these blood tests work for everyone in everyday life. This is because people in studies might not always be exactly like all the people affected by dementia. Projects like the Blood Biomarker Challenge in the UK are working to gather this proof. This work will be a big step in making diagnosis easier and faster, helping us get closer to finding a cure.

As the world continues to struggle with surges of COVID-19 alongside seasonal flu outbreaks, our attention naturally turns to the known protocols—masking, sanitizing, and social distancing. But amidst this heightened focus on respiratory health, have you ever caught yourself rubbing your eyes in public and instantly panicked, “Wait, what if I just exposed myself to COVID?”, I sure have! While we’ve masked up, sanitized hands religiously, and avoided touching elevator buttons with bare fingers, most of us have ignored a crucial entry point for viruses—our eyes.

From foggy glasses to burning dryness behind masks and marathon screen-time fatigue, your eyes have silently endured the pandemic’s worst. But here's the thing: your eyes aren’t just tired—they might actually be vulnerable to viral infection.

Your eyes are not only a window to the world, but also a possible gateway for infections like COVID-19. According to Dr. Anurag Wahi, ophthalmologist and eye surgeon, “The eyes are mucous membranes, just like the nose and mouth. They are exposed, vulnerable, and often touched without thinking. That makes them a potential entry point for viruses.”

While the primary transmission route for COVID-19 is through respiratory droplets, scientific studies and clinical observations have confirmed that SARS-CoV-2 can enter the body through the eyes. This happens when droplets land directly on the ocular surface during a cough or sneeze—or when a person touches a contaminated surface and then rubs their eyes.

Dr. Wahi explains, “We’ve seen patients with conjunctivitis and mild eye irritation test positive for COVID-19. Though eye-related symptoms are rare, they’re a warning sign that the virus can travel through ocular routes.”

More transmissible variants of COVID-19 have increased the likelihood of infections spreading even via minimal exposure, making eye hygiene and awareness more crucial than ever.

Unexpected Effects Of Long-Term Mask Use on Eyes

One of the lesser-known side effects of long-term mask use—especially poorly fitted masks—is mask-associated dry eye (MADE). When a mask directs air upward across the eyes, it speeds up tear evaporation. This results in redness, burning, irritation, or blurry vision, which may feel like mere discomfort but can indicate compromised ocular health.

“The issue became particularly evident among healthcare professionals who wore masks for prolonged periods,” says Dr. Wahi. “The lack of moisture and increased air flow over the eye’s surface led to an increase in dry eye cases.”

The problem is compounded by excessive screen time—a consequence of remote work, virtual classes, and increased digital consumption. Extended screentime can significantly reduce blink rate, affecting tear production and worsening dryness.

Smart Ways to Protect Your Vision

Keeping your eyes safe doesn’t require complex tasks, just informed action. Here's how you can keep your eyes safe and healthy:

1. Keep Hands Off Your Eyes

It may sound basic, but avoiding unnecessary eye contact with your fingers is one of the most effective protective habits. Always wash your hands before handling contact lenses or applying medication. “People underestimate how often they touch their eyes unconsciously,” warns Dr. Wahi.

2. Use Protective Eyewear

For healthcare workers, public-facing professionals, or those entering high-risk environments like hospitals, glasses or face shields offer an extra layer of protection against airborne droplets.

3. Tackle Dryness With Eye Drops

If you’re experiencing irritation or blurry vision, lubricating eye drops can help. Choose preservative-free artificial tears to restore moisture. Also, ensure your mask is properly fitted. A snug fit over the nose—with a pinched wire—minimizes upward airflow.

4. Follow the 20-20-20 Rule

To reduce digital eye strain, follow this golden rule: every 20 minutes, look at something 20 feet away for 20 seconds. It gives your eye muscles time to reset and recover, helping you blink naturally and maintain tear function.

Warning Signs You Shouldn’t Ignore

Symptoms like persistent redness, irritation, light sensitivity, or blurred vision shouldn’t be brushed off as screen fatigue. These signs may indicate dry eye syndrome, allergies, or even early signs of ocular infection.

Dr. Wahi cautions, “If symptoms persist for more than a day or two, or if they worsen, it’s important to see a specialist—especially if you’ve had a recent illness, fever, or exposure to COVID-19-positive individuals.”

Timely intervention can prevent complications and also ensure the symptoms are not related to systemic infections or autoimmune flare-ups triggered by the virus.

Don’t Overlook the Eyes in Your Hygiene Routine

We’ve come to associate pandemic hygiene with sanitizers, soap, and masks, but our eyes remain one of the most neglected entry points. This has to change.

“Eye care should be integrated into your daily COVID protection habits,” says Dr. Wahi. “Especially with newer variants and rising cases, it’s essential to treat the eyes not just as visual organs—but as parts of the body that need shielding, too.”

From children attending online classes to older adults stepping out for essentials, eye protection must become mainstream, not optional.

The pandemic has taught us that no part of our body operates in isolation. The eyes are connected not just to our nervous system, but to our immune defense as well. Neglecting them can leave us vulnerable in ways we didn’t expect.

And it’s not just about preventing COVID-19. Dry eyes, eye strain, and poor visual hygiene can lead to chronic problems if ignored. Preventive measures now can safeguard your long-term vision health.

Bathroom habits can reveal a lot about our health. While you may think of your bathroom routines as normal, even small and seemingly unimportant signs could lead to devastating diagnosis. When it comes to periods and menstruation related illnesses, many women are often dismissed regarding their concerns. The notion that pain and discomfort surrounding menstruation is normal and should be tolerated, has stopped many women from getting proper diagnoses.

Diseases like endometriosis, Uterine fibroids, Polycystic Ovarian Disorder/Syndrome (PCOS/PCOD) etc., affect many women worldwide, however the signs and symptoms of these diseases are often ignored or overlooked.

If you've noticed changes in your bowel habits, such as going to the toilet more or less often than usual, it might be time to see your doctor. The Endometriosis Foundation warns that this could be linked to an incurable condition affecting the bowel called Bowel Endometriosis.

What is Endometriosis?

Endometriosis, often shortened to "Endo," happens when tissue similar to the lining inside the womb starts growing outside of it. These growths, called lesions, can spread to many parts of the body. When these lesions affect your bowel or digestive system, it's called Bowel Endometriosis. The lesions can either stay on the surface of your bowel or grow deeper, causing a lot of discomfort and problems. This type of Endometriosis is most commonly found in the lower part of the intestine, where it can make it hard to empty your bowel.

Affecting many women globally, endometriosis is a chronic condition, with 190 million people experiencing it. It can cause extreme pain during periods, sexual intercourse, bowel movements, urination etc. The World Health Organization explains that the causes of endometriosis is still unknown and has no cure. The only relief people get is from managing the symptoms with medication and in some cases surgery.

Signs and Symptoms of Bowel Endometriosis

Pain when you have a bowel movement is the most common sign that you might have bowel Endometriosis. In more serious cases, you might even see blood in your poop.

It's important to remember that the signs of bowel Endometriosis can be different for everyone. Some people might only have one or two symptoms, while others might experience many of them all at once.

The symptoms listed below are often linked to bowel Endometriosis, but this isn't a complete list. There might be other signs too:

• Pain when you have a bowel movement
• Pain in your pelvic area
• Changes in how often you go to the toilet, like constipation (hard to go) or diarrhea (loose stools)
• A dull ache, sharp pain, or cramping in your lower belly and/or back
• Swelling in your belly
• Pain during or after eating certain foods
• Pain during sex
• Feeling like you need to have a bowel movement more often or very urgently
• Feeling like you can't completely empty your bowel
• Seeing blood in your poop

When to See a Doctor

If you're having unusual pain that makes it hard to do daily things like go to school or work, or if you notice changes in your periods or bowel habits, think about whether it could be Endometriosis or another problem. It's really important to talk to a doctor right away. When you do, make sure to mention Endometriosis and ask if you need to see a specialist. And remember, you always have the option to get a second opinion if you want.
