Making sure of your health before traveling is very important. Traveling is a strenuous activity that can take a huge toll on your body. Even if you are not walking the majority of the time or moving, the stress, time taken and coordinating important things can make you feel very tired. While the thought of relaxing on a holiday flight is exciting, a doctor reminds us that just like pilots do pre-flight checks, travelers should also take steps to protect their health.

If you are traveling by plane, you may not be as worried as there is not much movement required and no struggle with luggage after you hand it off. However, there could be another reason for worry lurking. Foot surgeon Dr. Dana Digura, who has a large following on Instagram, is raising awareness about the risk of Deep Vein Thrombosis (DVT) during long journeys.

Who Is At Risk Of Deep Vein Thrombosis?

According to the National Health Services UK, DVT is a blood clot that occurs in a vein, usually in the leg. Some symptoms of it include throbbing pain in one leg, swelling in one leg, warm skin around the painful area, swollen veins as well as darkened skin around the painful area. Dr. Digura points out that certain individuals face a greater risk of developing DVT on flights. These include:

• Those taking birth control pills
• Pregnant women
• Individuals with obesity
• People who have recently had surgery
• Smokers
• Individuals with varicose veins

In response to a query about a fiancée on birth control traveling by plane, Dr. Digura confirmed the risk, stating that flights over four hours, sometimes referred to as "economy class syndrome," can increase the likelihood of a "potential deathly blood clot called DVT." She further noted that this risk is even greater on flights exceeding six hours. According to the Anatolian Journal of Cardiology 2021, the name "economy class syndrome" comes from the fact that these blood clots often happen to passengers sitting in the more cramped economy section on long flights. However, it's not just about being in economy, it is because of a mix of things related to being on a plane and the person flying.

According to Mayo Clinic some other risk factors to consider are,

Age

Being older than 60, however it can happen at any age

Lack of movement

When there is no movement in your legs for a very long time, the calf muscles do not contract. The reason why this is concerning is because these muscle contractions help blood flow. So, sitting for too long, like flying or driving, could cause paralysis or a long visit to the hospital.

Smoking

Since it affects how the blood flows and could lead to clots, it can increase risk of DVT.

How Can You Reduce The Risk Of DVT

Dr. Digura offers straightforward advice for those concerned about blood clots during flights.

Move Around Regularly

Aim to get up and walk around every hour. This helps activate your calf muscles and prevents blood from pooling in your legs.

In-Seat Exercises

If you can't walk, engage your calf muscles with exercises like foot pumps (pointing and flexing your toes), calf raises, and ankle circles.

Dr. Digura also suggests that travelers of all ages consider using compression socks to help protect against blood clots. She specifically mentioned affordable options available from retailers like Boots and Amazon. These socks can aid in reducing swelling and improving blood circulation.

Boots further explains that compression socks can significantly improve circulation, support veins, and prevent leg swelling, blisters, shin splints, and general discomfort. If you experience symptoms of DVT along with breathlessness or chest pain, seek immediate medical attention by calling emergency services or going to the nearest emergency room.

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.
