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.

Summers are approaching and what would be better than having your own clothes that keep you cool? Scientists at the University of Alabama at Birmingham in the United States are working on innovations and have also applied for a patent. The research team led by Dr Vinoy Thomas, who is a native of Valakam in Kottarakkara. The findings have been published in the journal of the American Chemical Society.

What Is The New Finding Of Self-Cooling Fabric?

The researchers did not create a brand-new cooling fabric. Instead, they introduced a technique that transforms regular textiles into heat-regulating materials. This is done using two processes: electrospinning and plasma surface modification.

The first technique allows boron nitride nanoparticles to be evenly spread across the surface of the fabric. The second method uses low-temperature plasma (LTP) treatment to embed silicon oxide nanoparticles into the stitching threads.

Both boron nitride and silicon oxide are known for their heat-resistant qualities. By combining these two methods, researchers have created a coating that significantly lowers heat. The nanoparticles act as an added protective layer on the fabric.

Testing showed that the coating remains effective even after five to eight washes and does not affect the fabric’s original properties. Although its performance gradually decreases with repeated washing, researchers suggest applying a double-layer surface coating to improve durability.

Commercial production is expected to start once the patent is approved. In experiments, the coated garments reduced an external temperature of 35°C by 15°C, lowering it to 20°C. According to the researchers, this technique can be applied to any type of fabric.

Unlike earlier studies that focused on inventing entirely new heat-resistant materials, this innovation modifies existing fabrics. The study states that this approach is more efficient and cost-effective than current technologies.

The research team also includes Dr Ranjith Rajanpillai, Dr Kannadasan Appavu, Dr Claudiu T Lungu, and Dr Sanjay K Behura from the Department of Mechanical and Materials Engineering.

Innovations For Sizzling Summers

In Japan, something similar happened when former Sony engineer Hiroshi Ichigaya came up with kuchofuku or "fan jackets". This garment has a built-in feature, powered by battery, which is a fan at the lower back. This helps the circulation of air and to evaporate sweat and cool workers. These jackets are commonly used by construction workers, delivery partners, and people working in factory to combat extreme heat.

The meningococcal B vaccine (4CMenB) is completely ineffective in preventing gonorrhea -- a sexually transmitted infection (STI) --, especially among high-risk groups like gay and bisexual men, according to the results of the world’s largest randomized control trial (RCT).

Gonorrhea is a common bacterial STI caused by the bacterium Neisseria gonorrheae, and is transmitted through unprotected sex.

Even as antimicrobial resistance in gonorrhea has increased rapidly in recent years, Australian researchers explored the efficacy of 4CMenB against the disease.

The large randomized, placebo-controlled trial involving 587 gay and bisexual men showed that the risk of gonorrhea incidence remains essentially the same even after vaccination.

“Across both arms, the gonorrhea incidence was virtually the same -- at around 48 per cent per year, indicating very clearly that the vaccine had no effect on preventing gonorrhea,” said Professor Kate Seib, from Griffith University, in Australia, who led the trial.

In light of the study, the researchers stressed the need to explore other options to combat gonorrhea, such as condoms and regular testing.

The 4CMenB Vaccine

While meningococcal disease (caused by Neisseria meningitidis) and gonorrhea (caused by Neisseria gonorrhoeae) are distinct infections, both are caused by Neisseria bacteria, which share 80-90 percent genetic material.

The bacterium N. meningitidis primarily causes meningitis and septicemia, and observational studies have shown that meningococcal B (MenB) vaccines such as the 4CMenB offer 33-40 percent cross-protection against gonorrhea.

However, the latest study, presented at the Conference on Retroviruses and Opportunistic Infections in Denver, US, found no protection against gonorrhea.

The study “provides strong evidence that the 4CMenB meningococcal vaccine is not effective at preventing gonorrhea in gay and bisexual men who are at high risk of contracting it,” Seib said.

According to the US National Institute of Health, the 4CMenB vaccine is a highly effective, protein-based vaccine designed to protect against invasive meningococcal disease (IMD) serogroup B.

Approved in over 50 countries, it offers 71-95 percent effectiveness in infants and 100 percent in adolescents.

What Is Gonorrhea

Gonorrhea is a common STI, and sexually active people of any age can get the disease and pass it on to partners, and even to their baby during childbirth.

Gonorrhea is the second most common STI caused by bacteria, just behind chlamydia.

As per data from the World Health Organization (WHO), in 2020, there were an estimated 82.4 million new infections among adults globally.

The NIH noted that nearly 1 million new gonorrhea infections occur in the United States every year. About half of these infections occur in people ages 15 to 24.

The symptoms of Gonorrhea in men include:

• White, yellow, or green discharge from the penis
• Pain or burning (possibly severe) when peeing
• Testicular pain and swollen testicles.

Notably, the condition also occurs in women, but up to 50 percent of them won’t experience symptoms. This increases the risk of spread to other partners.

• Common symptoms in women include:
• Unusual vaginal discharge (white or yellow).
• Pain in your lower abdomen or pelvis.
• Pain during sexual intercourse
• Pain when you pee
• Bleeding between periods

A new study suggests that drinking sugary drinks can increase anxiety, among other mental issues, in adolescents by 34 percent.

Sugary drinks are known to be more harmful due to their low fiber, protein, or fat, which typically slow down digestion in solid foods. This means liquid sugar gets into your bloodstream very quickly, causing a sudden jump in blood sugar and insulin levels.

Hyper-fast intake of such drinks can also make it hard for your liver to process the sugar, especially the fructose part. n large amounts, fructose turns into fat in your liver. This buildup of fat is linked to metabolic problems that lead to Type 2 diabetes.

Apart from this, a Bournemouth University, UK literature review analyzed people aged between ten and 19 who drank fizzy drinks, colas, sweetened fruit juices, sweetened milk drinks, energy drinks, and sweetened tea or coffee and found multiple links between the beverages and anxiety diagnosis.

The gut-brain axis — the connection between the brain and the gut — may help explain the link between sugary drinks and anxiety. But gut health is influenced by many factors, including diet, stress, and sleep, which are also linked to anxiety.

Overall, the study suggests that cutting back on sugary drinks could help support teenagers’ mental health. While many studies have looked at how reducing sugary drinks improves physical health, more research is needed to see if it also benefits mental health.

WHO Asks Countries To Tax Sugary Drinks

The World Health Organization is asking countries across the world to increase taxes on sugary drinks and alcohol to reduce cases of chronic conditions such as Type 2 diabetes, obesity, heart disease and fatty liver.

In a January 13 virtual conference, WHO Director-General Dr Tedros Adhanom Ghebreyesus said: "Health taxes have been shown to reduce consumption of these harmful products, helping to prevent disease and reduce the burden on health systems.

"At the same time, they generate an income stream that governments can use to invest in health, education and social protection."

According to a recent report on sugar-sweetened beverages taxes, at least 116 countries tax sugary drinks, including sodas or carbonated canned drinks, but other high-sugar products, such as 100 per cent fruit juices, sweetened milk drinks and ready-to-drink coffees and teas, escape taxation.

Additionally, another report on alcohol taxes shows that even though 167 countries levy taxes on liquor, wine and beer, alcohol has become more affordable or remained unchanged in price in most countries since 2022, as taxes do not get adjusted for inflation and income growth.

How To Cut Back On Sugary Drinks?

Sugary drinks can feel addictive. If you find yourself hooked, try to slowly reduce how much you drink, just like you would with alcohol or tobacco. It helps to plan ahead for when you usually crave a soda.

You can start by mixing plain sparkling water with an equal amount of fruit juice or soda. Then, week by week, slowly reduce the amount of the sugary drink until you're mostly just drinking sparkling water. If it helps, add a little lemon or lime juice for flavor.
