It was a typical morning. My mother was getting ready; this was her usual routine: bustling around the house. When she suddenly stopped and shouted, blood was oozing from her nose. As kids, my siblings and I were terrified. We scrambled to help, but it wasn't until later that we learned the cause of that alarming moment: high blood pressure. That day was our first lesson in the silent yet powerful effects of hypertension. Nosebleeds, or epistaxis, are common, and nearly everyone experiences at least one in their lifetime.
While most are minor and often caused by dry air or irritation, some can signal underlying health concerns. One recurring question is whether high blood pressure causes nosebleeds or is merely coincidental.
The nose is covered by a rich plexus of small blood vessels, making it prone to bleeding. Most nosebleeds are anterior in origin, occurring at the front of the nose, and are relatively benign. They often occur because of irritants such as dry air, frequent nose-blowing, or trauma.
On the other hand, posterior nosebleeds are caused by a source that is located deeper within the nasal cavity. They are less common but more severe, as the blood tends to flow backward into the throat, making them more difficult to control. Common causes of posterior nosebleeds include trauma, medical conditions, or high blood pressure.
Hypertension is the condition whereby the pressure of blood against the arterial walls is consistently too high. Over time, this may damage the fine blood vessels in the nose, causing them to rupture more easily.
Significant studies have shown a strong relationship between hypertension and severe cases of nosebleeds necessitating urgent care. A certain study showed that patients diagnosed with high blood pressure had 2.7-fold increased chances of having nosebleeds that were not slight.
However, it should be noted that mild hypertension by itself does not cause nosebleeds. Nosebleeds are more likely to happen during a hypertensive crisis when the blood pressure suddenly rises to above 180/120. A hypertensive crisis can also have other symptoms such as a severe headache, shortness of breath, and anxiety. Therefore, it is considered a medical emergency.
Chronic hypertension makes the walls of blood vessels weaker and less elastic, which easily causes them to tear. In the nose, this is especially vulnerable because the blood vessels are close to the surface. Sudden surges in blood pressure, such as in a hypertensive crisis, can cause tears in these weakened vessels, resulting in nosebleeds.
While hypertension is a contributing cause, nosebleeds occur infrequently as the only manifestation of high blood pressure. This makes regular monitoring for blood pressure all the more crucial, as hypertension has the reputation of being the "silent killer" since people often do not present symptoms until the disease has run its course.
For most nosebleeds, you can manage them yourself at home:
1. Sit up and lean slightly forward to prevent swallowing blood.
2. Press your nostrils together for at least 10 minutes.
3. Use a cold compress on the bridge of your nose to constrict blood vessels.
4. If the bleeding continues, use a nasal decongestant spray.
Consult a doctor if the bleeding persists beyond 20 minutes, is heavy, or follows a head injury.
Preventive measures can decrease the incidence of nosebleeds:
For patients with hypertension, managing blood pressure is the best way to minimize the risk of complications. A combination of lifestyle changes, such as maintaining a healthy diet, regular exercise, and prescribed medications, can help keep blood pressure in check.
Most nosebleeds are harmless, but they can sometimes be signs of an underlying health condition. In adults with high blood pressure, frequent or severe nosebleeds should never be ignored. A health provider should be consulted in order to rule out any serious conditions and ensure appropriate treatment.
Regular check-ups, a healthy lifestyle, and awareness about the relationship between nosebleeds and high blood pressure would go a long way to protect your health. Indeed, prevention is always better than cure.

Higher temperatures in the US could increase heat-related heart disease by 200 per cent by 2050, according to an alarming study.
The research, published in JAMA Cardiology, predicts rising temperatures driven by climate change will dramatically increase heat-related heart disease in the US.
It is already known that extreme heat is detrimental to heart health and can potentially trigger heart attacks and other cardiovascular events.
"But this study is the first to map out exactly how bad the problem could get—county by county, across the US. It also highlighted how states with lower median household incomes are likely to face higher heat-related heart disease burden," said Gokul Parameswaran, research associate at the Case Western Reserve School of Medicine's Cardiovascular Research Institute and the study's lead author.
Researchers analyzed heart disease data in each county in the contiguous US from 2010 to 2016 to develop projections through 2050.
They found that the Pacific Northwest has the highest heat-related heart disease rate in the country. Southern states, however, are projected to see the steepest increases by 2050.
"Climate change is not just an environmental issue—it is a health equity crisis, and prioritizing vulnerable communities must be at the center of any heat mitigation strategy," said Salil Deo, associate professor in the Department of Surgery.

The study also found that aging — independent of temperature increases — will contribute an additional 34 per cent increase in heat-related heart disease by 2050, simply because there will be more older adults by then.
The study comes amidst more frequent heat events in the US, which is also lasting longer, and the temperatures during heat events are going up.
The past 10 years, from 2015 to 2024, were the hottest on record globally. But in cities across the United States, the average rate of extreme heat events increased from two per year in the 1960s to 10 per year between 2010 and 2020, according to Center for Climate and Energy Solutions (C2ES), a Washington-based NGO.

Additionally, as of 2024, the average length of heat-wave season in the US has increased by 46 days since the 1960s.
According to the Centers for Disease Control and Prevention, when temperatures rise, the heart must work harder to keep the body cool, and the likelihood of developing sudden clots in the bloodstream increases.

This extra stress on the heart due to high heat may lead to heart attacks or sudden worsening of heart disease, especially in the elderly or those with prior heart conditions.
"Climate change is not a distant, abstract threat," said Sanjay Rajagopalan, director of the Cardiovascular Research Institute and chief of Cardiovascular Medicine at University Hospitals Harrington Heart & Vascular Institute.
"It is a present and growing danger to the hearts of every American, and it is coming for the most vulnerable among us first. The choices made today about greenhouse gas emissions, urban planning, and health care policy will determine whether tens of thousands of Americans live or die from heat-related heart disease by 2050," he added.

Amid increasing contamination and adulteration of food products, India’s food regulator has introduced new safety standards across a wide range of foods such as besan (gram flour), edible and cold-pressed seed oils, as well as prawns.
The draft regulations by the Food Safety and Standards Authority of India (FSSAI) cover heavy metals, toxins, antibiotic residues, and quality standards for both commonly used foods and emerging edible products, the Times of India reported.
The new regulations are expected to come into force on December 1.
Under the new rules, the FSSAI has:
In a separate draft notification, the FSSAI proposed quality and safety standards for lesser-used edible oils made from chilli, tomato, muskmelon, and okra seeds as demand rises for cold-pressed oils, seed-based snacks, and plant-based nutrition products.
The proposed norms require these oils to remain free from adulteration, harmful impurities, rancidity, and mineral oil contamination, while also prescribing limits for moisture, acidity, and metal content.

The draft rules also cover edible seeds such as watermelon, cucumber, pumpkin, sunflower, sesame, and flaxseed sold in raw, roasted, or salted forms, requiring them to be clean and free from insects, fungus, and visible contamination before sale.
FSSAI has invited public comments on the draft regulations for 60 days before finalization.
In Ghaziabad, the state food regulator seized 10 quintals of suspected paneer stored in unhygienic conditions. With contamination risks high, the joint team swiftly sampled the batch and destroyed the entire 1,000 kg consignment.
In Muzaffarnagar, food safety officials inspected an ice cream outlet. The drive focused on ice creams and ice candies to ensure they met regulatory standards. A total of three legal samples were collected.

The FSSAI noted that hidden adulterants in everyday food can create serious concerns for consumers.
Food adulteration happens when there is an intentional addition of foreign or inferior substances to original food products.
A 2024 study published in SAGE Open Medicine noted various health impacts of adulterated food, including:
The study also noted that adulteration could lead to allergic reactions. Pregnant women, children, and the elderly are more prone to developing illnesses if adulterated food is consumed.

Do you smoke herbal cigarettes believing they are “natural”, “chemical-free”, and “tobacco-free”? You may be mistaken. New research, ahead of World No Tobacco Day 2026, has raised concerns over the growing popularity of herbal cigarettes, suggesting that herbal cigarettes are not safer than conventional cigarettes and may be equally harmful to health.
The new joint study by the Indian Institute of Technology Gandhinagar (IITGN) and the University of Illinois Urbana-Champaign (UIUC), US, has found that herbal cigarettes can produce emissions comparable to — and in some cases more harmful than — those generated by tobacco cigarettes.
The study, published in the Journal of Hazardous Materials, highlight significant health concerns surrounding herbal smoking products, many of which currently fall outside India’s primary tobacco control laws.
The study compared emissions from two of India’s best-selling tobacco cigarette brands and four popular herbal cigarette varieties containing ingredients such as basil, clove, cinnamon, mint, green tea, water lily, and chamomile.
Two of the herbal products also used tendu (ebony) leaves as wrappers — the same material commonly used in bidis, India’s most consumed smoking product.

Researchers analyzed the physical, chemical, and oxidative properties of mainstream smoke generated from the products. According to the study, herbal cigarette smoke released extremely fine particles and toxic compounds at levels similar to or exceeding those found in tobacco smoke.
“Our findings challenge the widely held belief that tobacco-free means risk-free. Emissions from herbal cigarettes are comparable to or exceed those from tobacco cigarettes on nearly every metric we measured. Leaf-wrapped herbal variants turned out to be the most hazardous of all the samples tested,” said Prof. Sameer Patel, Assistant Professor at IITGN’s Department of Civil Engineering and Chemical Engineering.
Further, the researchers combusted each cigarette inside a sealed automated two-chamber system designed to mimic human inhalation patterns, to decode particle size, chemical composition, and oxidative potential.
Shockingly, the team found that particles smaller than 500 nanometers — associated with cardiovascular and respiratory diseases — were emitted at nearly 20 per cent higher concentrations in herbal cigarette smoke compared to tobacco smoke.
The study also measured the “oxidative potential” (OP) of smoke particles — a marker of their ability to generate reactive oxygen species that contribute to inflammation, lung damage, and vascular disease.
According to the researchers, particulate matter from herbal cigarettes showed significantly higher oxidative potential than tobacco cigarettes. Tendu-leaf-wrapped variants recorded OP levels nearly 49 per cent higher than paper-wrapped products.
Notably, one basil-filled herbal cigarette marketed as “100% natural” and “chemical-free” showed the highest lead concentration among all products tested.
Prof. Vishal Verma, Associate Professor of Environmental Engineering at UIUC and co-author of the study, said the results are particularly significant because many consumers believe nicotine-free products are less harmful.
“That finding is important because many consumers associate nicotine-free products with reduced harm,” he said.

Researchers also pointed to regulatory loopholes surrounding herbal cigarettes. India’s Cigarettes and Other Tobacco Products Act (COTPA), 2003, regulates tobacco products through health warnings, advertising restrictions, and public smoking rules. However, many products marketed as tobacco-free do not fall under the same regulatory framework.
Lead author Dr. Alok Kumar Thakur said several herbal cigarette brands claim therapeutic benefits, including relief from cough, anxiety, and sleep problems, despite limited scientific evidence on their safety.
“However, there is limited scientific evidence evaluating the emissions and toxicological impacts of these products,” he said.
The findings also align with the World No Tobacco Day 2026 under the theme, “Unmasking the appeal: countering nicotine and tobacco addiction.”
The researchers stressed the urgent need for evidence-based regulation and stricter oversight of alternative smoking products to prevent misleading health claims and protect public health.
