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.

Where Exactly Does a Nosebleed Occur?

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.

Connection Between Nosebleeds and 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.

Why Does Hypertension Increase the Risk?

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.

Other Causes of Nosebleeds

  • Dry Air: Cold weather or house heating dries out membranes that line the nose, hence susceptible to cracking.
  • Trauma: Blows in the nose, nose picking or excessive nose blowing can traumatize blood vessels.
  • Intrinsic Disease: Liver disease and kidney disease and drug therapy that affect clotting such as blood thinners enhance the risk of nose bleeding.
  • Foreign Bodies: Children especially tend to insert objects up their noses, which can be irritating and bleed.
  • Allergies or Infections: Chronic nasal inflammation resulting from allergies or colds causes irritation to the nasal mucosa.

Managing Nosebleeds at Home

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.

Preventing Nosebleeds

Preventive measures can decrease the incidence of nosebleeds:

  • Use a humidifier to maintain moisture in the air.
  • Apply saline sprays or gels to keep nasal passages hydrated.
  • Avoid nasal trauma by being gentle when blowing your nose.

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.

When to Worry About Nosebleeds

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.

Working Out For 10 Minutes May Decrease Your Risk Of Colorectal Cancer, Study Proves

Updated Jan 7, 2026 | 05:38 PM IST

SummaryNewcastle University researchers have discovered that even short bouts of exercise can impact cell gene activity related to metabolism, tumor growth and inflammation which can help control the growth of cancerous cells in the colon or large intestine. Over 70,000 new cases of colorectal cancer occur annually in India, making it the fourth most common cancer in the country.

Performing short and intense exercises that last for about 10 minutes may significantly reduce the risk of colorectal cancer, a British study shows.

Researchers at Newcastle University have found that completing brief workouts increases the concentration of several small molecules in the blood that have previously been linked to reducing inflammation, improving blood vessel function and metabolism.

The findings, which were published in the International Journal of Cancer, also noted that even short bouts of exercise can influence the activity of genes that govern tumor growth and fight against cancer.

Dr Sam Orange, Senior Lecturer in Clinical Exercise Physiology at Newcastle University and lead study author, said of the results, "What’s remarkable is that exercise doesn’t just benefit healthy tissues, it sends powerful signals through the bloodstream that can directly influence thousands of genes in cancer cells.

“It’s an exciting insight because it opens the door to find ways that mimic or augment the biological effects of exercise, potentially improving cancer treatment and, crucially, patient outcomes.

“In the future, these insights could lead to new therapies that imitate the beneficial effects of exercise on how cells repair damaged DNA and use fuel for energy.”

How Does It Work?

The study involved 30 participants, both male and female between the ages of 50–78. All of the participants were overweight or obese (a risk factor of cancer) but otherwise healthy.

Researchers had asked each volunteer to complete a short, intense cycling test that lasted about 10 minutes and collected each of their blood samples which were then meticulously analyzed.

After studying about 249 proteins, the experts found nearly 13 protein had increased in their blood flow after the short exercise including interleukin-6 (IL-6), which helps repair the DNA of damaged cells.

When these exercise-induced proteins were applied to colorectal or bowel cancer cells by the scientists in a lab, they discovered that these new proteins could alter the activity of over 1,300 genes, particularly those who were responsible for DNA repair, energy production and cancer cell growth.

As a result, they concluded that performing even small exercises can activate a set of genes in the body's cells that can support efficient use of oxygen and promote energy metabolism. Additionally, the British researchers also discovered that the cell genes which have been previously associated with rapid cell growth were switched off after working out, suggesting that this might aid in controlling cancerous growths in the body.

What Is Colorectal Cancer?

Colorectal or bowel cancer is a common cancer that forms in the tissues of the colon (large intestine) or rectum, often starting as non-cancerous growths called polyps that turn cancerous over time.

Despite being treatable and preventable, colorectal cancer is currently the second leading cause of cancer-related deaths worldwide. Over 70,000 new cases of colorectal cancer occur annually in India, making it the fourth most common cancer in the country.

Typical symptoms usually include :

  • Blood in or on the stool
  • Changes in bowel habits (diarrhea, constipation, narrower stools)
  • Abdominal discomfort, cramps, gas, or pain
  • Feeling that your bowel doesn't empty completely
  • Weakness, fatigue, or unexplained weight loss
Some of the risk factors include risk factors involve being over the age 50, family history, certain genetic syndromes (like Lynch syndrome), inflammatory bowel diseases, and lifestyle factors (diet high in red meat, alcohol, smoking, inactivity). The most effective way to prevent colorectal cancer is through annual colonoscopies, screening and stool tests.

Expert Explains: Why Do Allergies And Rashes Increase In Winter? According To Dermatologist

Updated Jan 7, 2026 | 10:00 PM IST

SummaryWinter rashes and allergies increase as cold, dry air strips skin moisture and weakens its barrier. Indoor living raises exposure to dust, mold and pet dander, while hot showers and woolens worsen irritation. Experts say hydration, gentle bathing, moisturizers and avoiding triggers help prevent flare-ups during harsh winter months for seniors.

When temperature drops, so does the moisture even in your skin. This is what leads to a rash or allergies. In fact, with changes in temperature, and winters, our lifestyle changes too, this could also be the reason why we experience a winter rash, or allergies. To understand this better, Health and Me spoke to Dr Navjot Arora, Consultant Dermatologist, Dermaheal Skin and Clinic at Dwarka, Delhi, who explained that allergies and skin rashes tend to increase during winter due to both, environmental factors and changes in skin health. "Cold temperatures and low humidity levels reduce moisture in the air, leading to excessive dryness of the skin. When the skin becomes dry, its natural protective barrier weakens. This makes it more prone to irritation, inflammation, and allergic reactions."

Why Does Winter Weather Increase Chances Of Rashes And Allergies?

The doctor explains that during winter, people tend to stay indoors more, and it also increases their exposure to allergens like dust mites, mold, pet dander, and chemical fumes from heaters and cleaning products. "Limited ventilation and closed spaces allow these allergens to build up, triggering allergic responses and skin rashes, especially in individuals with sensitive skin or pre-existing conditions like eczema."

Cold weather also affects blood circulation to the skin. Reduced blood flow can slow down the skin’s repair process and weaken its defense against irritants and allergens. As a result, chronic skin conditions such as eczema, psoriasis, and contact dermatitis often worsen in winter, leading to itching, redness, flaking, and rashes.

Lifestyle Changes In Winter

Doctor also points out that during winters, our bathing habit changes. Dr Arora says, "Frequent hot showers strip away the skin’s natural oils, increasing dryness and irritation. In addition, wearing heavy woolen or synthetic clothing can cause friction, sweating, and contact allergies, particularly in skin folds, which can further contribute to rashes."

Common Symptoms Of Winter Rashes

  • flushing
  • swelling
  • itching
  • flaking skin
  • sensitivity
  • bumps
  • blisters

If not treated well, or in time, it can develop into more serious health threat, especially if you have a family history of

  • eczema or another type of dermatitis
  • psoriasis
  • rosacea
  • allergies
  • asthma
  • sensitive skin

What Are The Cures To Winter Rashes And Allergies?

The rise in allergies and rashes during winter is largely linked to dry weather, indoor allergen exposure, and skin barrier damage. Maintaining proper skin hydration, avoiding harsh soaps, limiting hot water exposure, and wearing skin-friendly fabrics can help reduce the risk of winter-related allergies and skin rashes.

Moisturizers are usually the first line of care for dry skin because they help trap moisture and prevent further dryness. Apply them multiple times a day, especially after bathing or washing your hands. Thicker options like creams or ointments tend to keep skin hydrated longer than lighter lotions.

Petroleum jelly can also be effective, as it forms a protective barrier that seals in moisture. If you prefer to avoid petroleum-based products, alternatives like Waxelene or Un-Petroleum work in a similar way to reduce moisture loss.

Natural virgin oils, such as coconut oil, may help calm irritated skin and restore hydration. Use them on areas that are not acne-prone, and always do a patch test on a small area for 24 hours before wider application.

Oatmeal-based soaps or oatmeal baths can also help soothe dry, itchy skin. You can buy ready-made oatmeal soaps or add finely ground oats to a warm bath and soak for about 10 minutes.

For itching and inflammation, topical hydrocortisone creams, available over the counter or by prescription, may provide relief. Always follow the instructions on the label or use them as advised by a doctor.

The NHS has released updated guidance for people who are currently taking clonazepam, a commonly prescribed medicine that belongs to the benzodiazepine group. According to the health service, clonazepam is often used to control seizures or fits linked to epilepsy, ease involuntary muscle spasms, and help manage panic disorders. It is also prescribed in some cases for people with restless legs syndrome (RLS). NHS Inform notes that “around 1 in 10 people experience restless legs syndrome at some stage in their life.”

Explaining how the drug works, the NHS says it increases levels of gamma-aminobutyric acid (GABA), a chemical in the brain that has a calming effect. By boosting GABA, clonazepam can reduce anxiety, prevent seizures or fits, and relax tight or overactive muscles.

Who Can Take Clonazepam?

Clonazepam is only available on prescription and comes as tablets or a liquid. Most adults aged 18 and over can take either form. In certain cases, children as young as one month old may be prescribed clonazepam to treat epilepsy, as per NHS.

That said, there are situations where extra caution is needed. People who are due to have surgery or dental treatment, those who are pregnant, trying to conceive, or who have sleep-related conditions may be advised to stop taking the medicine. However, these are not the only groups the NHS says should be careful.

Clonazepam is not suitable for everyone. Before starting treatment, patients are advised to tell their doctor if they:

  • have ever had an allergic reaction to clonazepam or any other medicine
  • have myasthenia gravis, a condition that causes muscle weakness
  • have sleep apnoea, which affects breathing during sleep
  • have lung, liver, or kidney problems
  • have spinal or cerebellar ataxia, which can cause shakiness, poor balance, and slurred speech
  • have had problems with alcohol or drug use in the past
  • have recently experienced bereavement, depression, or thoughts of self-harm or suicide
  • have been diagnosed with a personality disorder
  • are trying to get pregnant, are already pregnant, or are breastfeeding
  • are due to have a general anaesthetic for an operation or dental procedure

What Are The Side Effects Of Clonazepam?

Like many medicines, clonazepam can cause side effects. Common effects, which affect more than 1 in 100 people, include disturbed sleep such as vivid dreams, feeling sleepy during the day, light-headedness, dizziness, unsteadiness, and muscle weakness.

When it comes to long-term use, the NHS warns that clonazepam can lead to withdrawal symptoms if taken for a prolonged period. Because of this risk, people who have been prescribed the drug for more than four weeks may have their dose reduced slowly when stopping treatment, rather than stopping suddenly.

The NHS also stresses that this is not a complete list of side effects. Patients are advised to read the information leaflet that comes with their medicine for full details.

Clonazepam: Serious Side Effects To Watch Out For

Although uncommon, some people may experience serious side effects while taking clonazepam. The NHS advises contacting a doctor or calling 111 immediately if you notice:

  • yellowing of the whites of the eyes or skin, which may be less noticeable on darker skin tones, as this could point to liver problems
  • seeing or hearing things that are not there, or believing things that are untrue
  • problems with coordination or controlling movements
  • swollen ankles, a fast heartbeat, coughing, and extreme tiredness, which could be signs of heart issues
  • easy bruising, fatigue, nosebleeds, and breathlessness, which may indicate blood disorders
  • changes in mood, such as talking more than usual, feeling unusually excited, restless, irritable, or aggressive, which are more likely in children or adults over 65
  • Anyone experiencing memory problems, such as difficulty remembering things or amnesia, is advised to book an appointment with their doctor.

In rare cases, clonazepam can trigger a serious allergic reaction known as anaphylaxis.
