Have you ever noticed the small, raised bumps on your nose? The ones who have noticed these, often find themselves looking for what they are – if they are harmless or not and how to get rid of them. This prompts many people to assume that they are blackheads, however they are still unsuccessful at removing them.

Here’s Why

In reality, these dark spots are not blackheads but a common and normal part of your skin. Recently, Dr Neera Nathan, a dermatologist and researcher at Massachusetts General Hospital took to social media to talk about the same. In her video, she explained what these raised bumps on our nose are. “These little dots are not blackheads. They are completely normal structures we all have called sebaceous filaments,” she said.

What Are Sebaceous Filaments?

Sebaceous filaments are like tiny, thin strands or tubes that live inside your oil glands also called sebaceous glands. Their job is to help move a greasy liquid called sebum from these glands up to the surface of your skin. Think of them as little pipelines for your skin's natural oil.

The Cleveland Clinic explains that these dark spots are a normal and healthy part of your skin. They play an important role in helping the sebum get to where it needs to be, that is on the epidermis. The sebum that these filaments help move is actually good for you. It helps to keep your skin and hair moisturized so they don't get dry and also gives them a natural shine. So, these little filaments are actually your skin's helpers.

Tips To Make Dark Spots Less Noticeable

Even though these sebaceous filaments are a normal part of our skin, Dr Nathan did give her three best tips for people who want to make them less visible:

• “Massage this sulfur treatment into your sebaceous filaments and leave it on for 10 minutes before rinsing off.”
• She also said that salicylic acid, which you can find in some face washes, can help to "melt away" these filaments by cleaning deep inside your pores and getting rid of extra oil and dirt without hurting your skin.
• Lastly, she said that a product called adapalene, which you usually need a prescription for in the UK under the name Differin, can also help to dissolve these filaments and make the skin on your nose look smoother.

How To Deal with Oily Skin

The oil on your skin can be a result of various factors like your genes, how old you are, the weather, stress, and what you eat. You can't really change if your skin is naturally oily, but having a good skincare routine can help manage it. Experts suggest washing your face twice a day and after you exercise, avoiding harsh products, not scrubbing your face too hard, using a gentle toner, using a light moisturizer and sunscreen, drinking enough water, and trying not to touch your face too much during the day.

Heart diseases are one of the most common issues people face in the world. Despite being the leading cause of death globally, according to the world health organization, many people miss critical signs of it. The best way to ensure a person gets treatment, is that the disease must be diagnosed in its early stages. A new study suggests diagnosing the risk of heart disease early is also possible, with the help of eye scans.

Researchers at McMaster University and the Population Health Research Institute (PHRI) have made an incredible discovery. They found that the tiny blood vessels in your eyes could be a powerful way to guess how likely you are to develop heart disease and how fast your body is truly aging on the inside. This is a big deal because right now, checking for these risks involves many complicated tests.

The study, which was published in the journal Science Advances, suggests that soon, doctors might be able to use a simple scan of your retina, which is the back of your eye, as a quick and non-invasive tool. This scan could show them the overall health of your blood circulation and reveal your body’s real biological age. This new method could open up amazing possibilities for catching serious health issues much earlier.

Can You Diagnose Heart Diseases From Eye Scan?

The study was massive, involving over 74,000 people from large international research groups. The scientists analyzed their retinal images, genetic makeup, and blood data.

Their key discovery was striking, people whose blood vessels in the retina were simpler and looked less branched (not as tree-like) were found to be at a higher risk for heart problems. These same people also showed clear signs of faster biological aging, meaning they had more inflammation in their bodies and a potentially shorter life expectancy.

Dr. Marie Pigeyre, one of the main researchers on the study, explains that the eye is unique. It gives doctors a special, clear, and easy way to look at your entire circulatory system—all the veins and arteries that carry blood throughout your body.

Mirroring the Body

Think of the eye's small blood vessels like a mirror. Changes happening in these vessels reflect the same changes happening in the small blood vessels everywhere else in your body. If the vessels in your eye look unhealthy, chances are, the vessels around your heart and brain are also struggling.

Molecular Clues

The team didn't just look at pictures. By combining the retinal scans with genetic information and blood test results, they were able to uncover specific "molecular pathways." These are basically the biological rules or processes that explain exactly how aging causes problems in your blood vessel system.

Can You Cure Genetic Heart Diseases?

The researchers went beyond just finding a link; they used the blood and genetic data to hunt for the root causes of these eye vessel changes. This led them to pinpoint specific proteins that appear to be the main drivers of both aging and disease.

They identified two major proteins: MMP12 and IgG–Fc receptor IIb. Both of these are strongly linked to inflammation and the deterioration of blood vessels as we age.

Dr. Pigeyre is excited because these specific proteins could become targets for new drugs. Medicines designed to control or slow down these proteins could help reduce the impact of vascular aging, lower the risk of heart disease, and ultimately help people live longer and healthier lives.

Right now, to check for serious age-related diseases like heart disease, stroke, and memory problems (dementia), doctors have to perform many different tests. The big hope is that a quick, simple retinal scan could one day become an easy-to-access tool to immediately check a person's risk for heart problems and determine their biological age.

It is not uncommon for women’s health concerns to be overlooked even by professionals. Often chalking up their health issues as, ‘common women ailments’, many healthcare professionals, miss the core reason for women’s symptoms. In a recent video, Dr Karan Rajan, an NHS Surgeon, shared a video, explaining how often, even signs of chronic illnesses can get overlooked as just ‘anxiety’.

So, is there no way a person can ensure they have the right diagnosis? In the video Dr Karan listed a few ways one can ensure they have the right diagnosis, from asking the right questions and how to proficiently communicate your symptoms to the doctor.

What Questions Should You Ask Your Doctor?

If your doctor told you that your health problems are "just anxiety," remember that you have the right to push for a more thorough checkup. One should ask the right questions as it is their health on the line. Being ready shows you're serious and ensures your doctor looks into your condition properly.

Dr. Karan explains that when talking to your doctor, you should ask questions that make them explain why they settled on an anxiety diagnosis. This shifts the focus back to the doctor, requiring them to justify their medical opinion. Here are the key questions you should use.

"What tests have been done to rule out other causes of my symptoms?"

This question is powerful because it makes the doctor list exactly what they have investigated. It clarifies the boundaries of the investigation. If the doctor hasn't run many tests, you know there's more ground to cover.

"Can you explain why you think this is anxiety and not a physical medical condition?"

Don't accept "your blood work is fine" as the only answer. That's often not enough. Many serious health conditions don't show up on a routine blood test. You want a detailed explanation of their thinking, not just a quick dismissal.

"Have we ruled out other conditions that can look exactly like anxiety?"

It's surprising how many physical illnesses have symptoms that are identical to anxiety. Dr Karan explains how thyroid problems like hypothyroidism, issues with your nervous system like dysautonomia, or even an immune disorder like mast cell activation syndrome, can all cause symptoms like a racing heart, dizziness, or panic. You want to be sure these possibilities have been considered.

Is It Anxiety Or A Health Condition?

If your doctor only suggests things like talk therapy and certain medications (like SSRIs), be prepared to ask for more. You need to know if they're looking at the big picture.

Dr Karan suggests that you should ask them: "What treatment plan would you suggest that goes beyond just treating the anxiety itself?"

If their only answer is medication and counseling, it's fair to ask what other medical routes or specialists can be explored to find the root cause of your symptoms.

How Should You Describe Your Symptoms?

When describing your symptoms, you need to be precise and give the doctor hard data. This makes it much harder for them to brush off your concerns as simple stress. Dr Karan gives an example, instead of just saying, "I get dizzy a lot," get into the details:

"I get dizzy when I stand up, especially in the morning. It's worse after eating or after I’ve been sitting for a long period of time."

This kind of specific detail is very important. Symptoms that happen when you stand up and improve when you lie down could point to a physical problem like Postural Orthostatic Tachycardia Syndrome (POTS), not just everyday anxiety.

The clearer and more factual you are, the less likely they are to dismiss your condition as just "generalized stress." Dr. Rajan emphasizes that "data talks." Start keeping a symptom diary right away! It's an essential tool for tracking your condition every day. In your log, record:

The exact time symptoms happened.

What you ate or drank beforehand.

What made the symptoms better or worse.

Look for patterns. Does the dizziness only happen after you stand up? Do your symptoms worsen after a certain meal, or around your sleep schedule, or with hormonal changes? Bringing this detailed log, to your appointment makes it much, much more difficult for any doctor to doubt or dismiss your concerns.

With Delhi winters coming in, the spell of late smog is most likely to stay not just outside the homes, but it could in fact, follow you inside your homes. A study by the University of Delhi's Satyawati College, Jamia Millia Islamia, and US's South Dakota University, reveal that bacterial levels were recorded to be 10 fold higher than the World Health Organization (WHO) recommended safety limits.

Studies have also found that air inside the city homes have 12 times more fungal spokes than the WHO safety limits. They can cause skin allergies, respiratory issues, and anxiety. As per a 2021 study by the Energy Policy Institute at the University of Chicago (EPIC India), PM 2.5 levels for low-income and high-income households in Delhi were high during the winters. The concentrations reported 23 and 29 times higher than the WHO safe limits, respectively. These findings also suggested that high-income households were 13 times more likely to own air purifiers than low-income households.

In Delhi, No One Gets To Breathe

Dr Kenneth Lee, who was the lead author of the study said, "In Delhi, the bottom line is - whether someone is rich or poor, no one gets to breathe clean air."

Lee further adds, "It’s a complex vicious cycle. When you do not know about the pollution levels inside your homes, you do not worry about it, and hence you are less likely to take corrective actions. Only with increased awareness, demand for clean air may gain momentum.”

The study also found that indoor PM2.5 levels were higher than the value reported by the nearest government monitor. The PM2.5 levels spiked in the mornings and evenings when households were most likely to be cooking.

The recent study published in Frontiers in Public Health 2025 notes that long term exposure to high fungal and bacterial concentration make indoor air in several parts of Delhi as harmful as the smog outside. The study also noted that most fungal particles were smaller than 2.5 microns, this is why they can easily penetrate through your bloodstreams.

The study revealed a distinct seasonal trend in indoor air quality across Delhi. Fungal levels rose steadily from winter, peaking at around 6,050 CFU per cubic metre between September and November, just before the city’s infamous smog season. Bacterial concentrations, meanwhile, climbed from winter to summer, reaching their highest levels in August before tapering off in the fall.

Health complaints among residents were widespread: 33% reported frequent headaches, 23% experienced burning or irritated eyes, 22% suffered persistent coughing or breathlessness, and 18% struggled with sneezing and allergic rhinitis. Another 15% reported skin irritation and itching.

Who Are At Most Risk Of Indoor Pollution?

The study highlighted that children and young adults were particularly vulnerable, about 28% of children under 12 and 25% of young adults (18–30 years) experienced breathing difficulties, coughing, or allergy-related symptoms. Researchers attributed children’s higher susceptibility to developing lungs, increased physical activity, and longer indoor exposure.

Women also reported more eye and skin problems, making up nearly 60% of dermatological and eye irritation cases, likely due to spending more time indoors.

Conducted over a year in North Delhi, the study, “Microbial Indoor Air Quality Assessment and Health Correlations in Densely Populated Urban Areas of Delhi, India”, found that fungal and bacterial levels inside homes were several times higher than WHO’s safe limits, underscoring that Delhi’s pollution crisis extends well beyond outdoor air.
