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.

Harry Potter star Daniel Radcliffe has quit smoking after 20 long years. The reason: his two–year–old son with girlfriend Erin Darke.
Speaking to media outlet Vulture, the 36-year-old English actor shared that after becoming a father, he was inspired by intrusive thoughts about his mortality, which enabled him to quit the deadly habit after two decades.
"I smoked for 20 years pretty heavily, and I was never even thinking about quitting, and then shortly after having my son, the intrusive thoughts of my own death really helped as an incentive to quit," Radcliffe was quoted as saying.
Radcliffe also shared how a book -- The Easy Way to Quit Smoking, by Alan Carr -- helped him decide to quit smoking.
"It may not work for everybody, but it really worked for me," noted the star, currently starring in the Broadway play Every Brilliant Thing.
Earlier this month, the actor spoke with WSJ Magazine and shared that from being on “cigarettes all day”, he's transformed into a fitness freak.
Smoking can affect all organs in our body. While lung cancer and tuberculosis are the most prominent ones, smoking can seriously increase the risk of several chronic diseases. These include:
While quitting tobacco is important, it is a difficult task, with some people finding it harder to quit than others. It may be important to seek help quitting.

These strategies have shown varying levels of success in aiding smokers to quit permanently. In addition, alternative methods like e-cigarettes and mindfulness-based techniques have gained traction in helping reduce smoking addiction.
Behavioral Support
Quitting smoking isn’t just about resisting cravings. Often, behavioral support through counseling or therapy is crucial for tackling the psychological aspects of addiction. Behavioral therapy involves working with a trained professional to identify triggers, develop coping strategies, and create a tailored quit plan. Research shows that combining counseling with other quit methods can significantly increase success rates.
Prescription Medications
Some medications, such as varenicline (Chantix) and bupropion (Zyban), have been shown to help people quit smoking by reducing cravings and withdrawal symptoms. Experts suggest that varenicline works by blocking the effects of nicotine in the brain, while bupropion is an antidepressant that helps manage withdrawal symptoms. Both medications are generally more effective when combined with behavioral therapy.
Nicotine Replacement Therapy (NRT)
Nicotine replacement products, such as nicotine patches, gums, lozenges, and nasal sprays, deliver controlled amounts of nicotine to ease withdrawal symptoms. According to experts at Harvard Health, NRT can double the chances of quitting by alleviating physical cravings while the person works on overcoming the psychological addiction.

About 10.6 percent –15 percent of India's population suffers from some form of mental health conditions, with 15 percent of the adult population also requiring active intervention.
To enable researchers to gather as well as systematically document data on patients with major forms of mental illness, neuroscientists in India have developed CALM-Brain — a digital repository of data on brain structure and function from a range of psychiatric disorders.
CALM-Brain contains data from over 2,000 participants from 900 families across the country.
CALM-Brain will help clinicians and researchers
“CALM-Brain was conceived as a method to assemble data from multiple scales of analysis of brain structure and function on a single platform. We believe that the application of modern methods of data analysis to this dataset will help bridge the gap between these scales of analysis,” said Prof. Raghu Padinjat, CBM co-ordinator at CBM-NCBS, in a statement.

CALM-Brain is the result of collaborative efforts of researchers at the Rohini Nilekani Centre for Brain and Mind (CBM) — a partnership between the National Institute of Mental Health and Neuro Sciences (NIMHANS) and the National Centre for Biological Sciences (NCBS) - TIFR.
CALM-Brain is India’s first-of-its-kind repository of clinical, neuroimaging, behavioral, genetic, and other datasets on disorders such as:
The dataset is also linked to a biorepository of stem cells, which can be used to perform biological research in psychiatry to understand the origins of such severe mental illnesses.
“The primary goals of the project are to identify biological markers of severe psychiatric illnesses, which cut across traditional diagnostic frameworks. In addition, we will try to identify fundamental biological mechanisms of the disease and medication response,” said Prof. Y.C. Janardhan Reddy, CBM coordinator at CBM-NIMHANS.
Mental wellness is a major health and economic concern in India. The World Health Organization (WHO) estimates India’s economic loss due to mental health conditions to be USD 1.03 trillion (2012-2030).
Recently, health experts and policymakers, as part of the government-led Post-Budget Webinar series, highlighted the growing burden of mental and neurological disorders in India and also stressed the urgent need to strengthen institutional capacity to meet emerging healthcare demands.
"One in seven Indians is affected by mental health disorders, while several states continue to face a treatment gap ranging from 70 to 90 percent," the experts said.
They added that "neurological and mental health conditions are among the leading contributors to disability-adjusted life years (DALYs)" among citizens.
To address the rising burden, the government aims to launch NIMHANS-2 — first announced by Finance Minister Nirmala Sitharaman during the Union Budget 2026-27 — to deliver specialized care for mental health and neurological disorders in north India.
"In addition, the Central Institute of Psychiatry, Ranchi, and the Lokopriya Gopinath Bordoloi Regional Institute of Mental Health, Tezpur, will be upgraded as regional apex institutions to strengthen mental healthcare services in the eastern and north-eastern regions," FM Sitharaman said.

Metformin has remained the safe and most effective first-line treatment for Type 2 diabetes for the last 60 years. The anti-diabetic drug has been known to work through the liver and gut to lower blood sugar levels and improve the way the body handles insulin.
However, a new study has, for the first time, shown that metformin probably works through the brain, and neurons in a specific region boost its anti-diabetic effects.
The findings open up potential for more targeted and effective diabetes therapies as well as for improving brain health.
The international team of researchers led by those at Baylor College of Medicine, in the US, decoded a brain-based pathway involved in metformin's ability to lower blood sugar.
They found that the widely used diabetes medication switches off a key protein and activates specific neurons, and lowers blood sugar through a previously hidden pathway.
"Metformin is not just working in the liver or the gut, it's also acting in the brain. We found that while the liver and intestines need high concentrations of the drug to respond, the brain reacts to much lower levels," said corresponding author Dr. Makoto Fukuda, associate professor of pediatrics - nutrition at Baylor.
The new study, published in Science Advances, targeted a small protein called Rap1 -- located in a brain region known as the ventromedial hypothalamus (VMH).
Mice studies proved that metformin fights blood sugar by suppressing the activity of Rap1 in VMH.
To prove the findings, the team deployed genetically engineered mice without Rap1 in the brain.
In mice with a high-fat diet that models type 2 diabetes, low doses of metformin did not improve their blood sugar levels.
On the contrary, when metformin was delivered in very small amounts directly into the brains of diabetic mice, it effectively lowered blood sugar levels.
Further, the team found that SF1 neurons located in the VMH are helping metformin to fight diabetes.
When the team measured the electrical activity of these neurons, they found that metformin’s activity increased only when Rap1 was present
The findings demonstrated that Rap1 is required for metformin to activate these brain cells and regulate blood sugar.
"This discovery changes how we think about metformin," Dr. Fukuda said.

Metformin has also shown potential to boost fertility levels in people with polycystic ovary syndrome (PCOS) -- a condition that affects how the ovaries work.
Metformin treats PCOS by lowering insulin and blood sugar levels. This can also improve ovulation and encourage regular periods.
Metformin has previously shown its potential for slowing brain aging and improve lifespan.
While metformin is safe for most adults and children aged 10 years and older, the drug may not suitable for some people. this includes people who:
