Scratching an itch can be really satisfying but also annoying at times. You often find yourself mindlessly scratching your arms or whatever skin is exposed as these are the places mosquitos commonly bite. While this is may not be a significant activity, it is when you catch an infection or start feeling itchy because of any allergen, it can become difficult to navigate. Many people even hurt themselves while itching because, even though it hurts, the itch needs to be scratched otherwise it will drive you crazy! Doctors often advise people not to scratch wounds and inflamed areas as it can become worse and infect existing wounds.

A recent study published in the Science Journal has revealed something interesting. The itch-scratch cycle is very fundamental in allergic dermatitis and arthropod reactions, in which itching and scratching feed back into the cycle and enhance inflammation to worsen the disease. Such research underlines the evolutionary aspect of scratching by serving a purpose through a neuroimmune axis despite its pathogenic nature. It reconciles apparently paradoxical properties of scratching by considering both roles of scratching—pathological and potential adaptive responses.

Scratching an itch is something we all do, but it turns out there's more to it than just habit. New research shows that scratching is actually a complex process with both positive and negative effects. While it can make skin inflammation worse, it also helps the body fight off infections by bringing immune cells to the skin's surface. This discovery helps explain why we scratch and offers hope for better treatments for chronic itch or skin conditions. It's a bit of a puzzle: how can something which is bad for your skin actually be helpful? This research helps us understand that paradox.

Why Do We Always Scratch An Itch?

When something itches, our natural reaction is to scratch. This is especially true with skin conditions like dermatitis or bug bites. The problem is that scratching often makes things worse, creating a vicious cycle- the more you scratch, the more inflamed your skin gets, and the itchier you feel. This "itch-scratch cycle" can be really hard to break. It's not like pain, which usually stops us from doing something that hurts. Scratching, even though it can be damaging in the long run, often feels good in the moment, which makes it hard to resist.

What Happens When You Scratch Your Skin?

Scientists wanted to understand exactly what happens when we scratch. Researchers used special mice to study how certain nerve cells that sense itching, called NP2 neurons, affect inflammation. They found that scratching activates pain-sensing nerves. These nerves then release a chemical called substance P (SP). SP then triggers immune cells called mast cells. These mast cells release other chemicals that attract white blood cells to the area, causing inflammation. So, scratching sets off a chain reaction that leads to inflammation.

Surprising Benefits of Scratching

Even though scratching can worsen skin conditions like dermatitis, it also has a surprising benefit: it helps the body fight infections. It seems that scratching can help reduce the amount of harmful bacteria, like Staphylococcus aureus, at the site of an injury. It might even play a role in balancing the skin's microbiome – the community of microorganisms living on our skin. However, this is a complex relationship, especially for people with chronic skin conditions like eczema, where scratching can disrupt the microbiome and worsen the condition.

Reasons Why An Itch Could Be Sign Of An Underlying Disease

According to Cleveland Clinic, where and when the itch is happening does matter in understanding whether it is an issue if not. Some people itch even when they are asleep and there have been cases of people itching themselves till they draw blood even in their sleep. A 2019 study done by the American Academy of Dermatology concluded that itching related to a liver disease starts at the palm of your hand and spreads, similarly and iron deficiency or anemia related itch could develop as red and bumpy skin that feels sore when you scratch it, it is called an anemia rash. Any itch that persists for a long time should be checked out by a doctor.

This new research suggests that scratching isn't just a bad habit; it's actually an ancient defense mechanism that evolved to protect us from infection. While it can be harmful in some situations, it also plays a role in our immune system's response to injury. Scientists believe that understanding this complex process could lead to new and better treatments for chronic itching.

Every two seconds, someone in the world needs blood—but far too few people step forward to donate. Whether it’s for accident victims, cancer patients, or those undergoing major surgeries, the demand for safe, healthy blood is constant and often urgent. Yet many potential donors hesitate, held back by fear, misinformation, or uncertainty. On World Blood Donor Day and beyond, it’s time to break down those doubts, understand the life-saving impact of one donation, and discover how giving blood could be easier—and more rewarding—than you think.

While blood donation is widely regarded as an act of altruism, what often goes unnoticed is the remarkable impact it has—not just on the recipients, but also on the donors themselves. Despite major awareness campaigns, myths and fears still prevent a significant portion of eligible individuals from rolling up their sleeves.

Every single blood donation has the potential to save up to three lives. According to Dr. Lopita Bhattacharya, a medical officer blood bank at BM Birla Heart Hospital, “One pint of donated blood is separated into red cells, plasma, and platelets, each of which can be administered to patients based on individual needs—be it trauma victims, cancer patients, surgical patients, or those with chronic blood disorders.”

At any NABH-accredited blood bank, no part of donated blood goes to waste. “Safety, accuracy, and quality are given utmost priority. The entire process is handled with the latest technology and rigorous screening,” she adds.

Dr. Umakant Mokalikar, Blood Centre Incharge at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune echoes the sentiment. “There is no substitute for human blood. Every donor plays a vital role in the healthcare system, especially in emergencies. Blood donation is truly a humanitarian act.”

Busting Common Myths Around Blood Donation

Despite awareness, misinformation continues to hinder blood donation drives. Experts say that correcting these myths is the first step to building a more robust and reliable donor base.

Myth 1: Blood donation makes you weak.

Fact: “The fluid components are replaced within 24 hours, and red blood cells regenerate within weeks,” says Dr. Bhattacharya. Healthy men can safely donate every 3 months; women, every 4 months.

Myth 2: The process is painful or too time-consuming.

Fact: “The blood draw itself only takes 8–10 minutes. Including the screening and post-donation rest, the entire visit wraps up in under 45 minutes,” Dr. Bhattacharya clarifies.

Myth 3: Only rare blood types are needed.

Fact: Common blood types are often in higher demand due to their compatibility across patient populations. “Every blood type is essential—be it for surgeries, maternity care, or injuries,” she notes.

Myth 4: Older adults or thin individuals should not donate.

Fact: If you're between 18–65 years, in good health, and meet minimum weight and hemoglobin thresholds, you’re eligible. First-time donors can donate until age 60.

Myth 5: Women can't donate blood.

Fact: “Aside from temporary conditions like menstruation or lactation, women can and should donate blood if they meet eligibility,” Dr. Mokalikar emphasizes.

Myth 6: Blood donation may cause infections.

Fact: The process uses sterile, one-time-use equipment. “There’s zero risk of catching infections,” he reassures.

Are There Any Health Benefits for Donors?

Donating blood is not just a selfless gesture; it comes with tangible health perks.

Improved heart health: “Regular donation helps lower iron overload in the body, which is linked to reduced risk of cardiovascular diseases,” Dr. Bhattacharya shares.

Calorie burn: One blood donation session can burn around 600–650 calories, similar to a light workout.

Stimulates red blood cell production: “Donation encourages bone marrow to generate fresh red cells, helping keep your circulatory system active,” she explains.

A mini health screening: Donors undergo blood pressure, hemoglobin, and pulse checks. Blood is also screened for infections like HIV, Hepatitis B & C, providing an early warning system for the donor’s own health.

Mental well-being: “The psychological benefit—knowing you’ve potentially saved lives—releases endorphins and improves mood,” adds Dr. Mokalikar.

What Happens To Your Body After Donating Blood?

Once donated, your blood is processed into three core components:

Packed Red Blood Cells (PRBCs): Used in trauma, surgeries, and patients with anemia or cancer.

Platelet Concentrates: Vital for patients with clotting disorders, infections, or undergoing chemotherapy.

Fresh Frozen Plasma (FFP): Used in patients with liver failure or bleeding disorders.

This separation maximizes the utility of a single donation—reaching three different patients with three different medical needs.

According to WHO, less than 1% of the eligible population donates blood in many countries—a number that needs urgent improvement. “If more people come forward regularly, hospitals will have the reserves to act swiftly during crises like accidents, natural disasters, or major surgeries,” urges Dr. Mokalikar.

He adds, “Blood donation is not a one-time favor. Men can donate every 3 months, and women every 4 months. Routine donations help keep blood stocks consistent and reliable.”

Blood donation is one of the most powerful acts of human kindness, and one of the simplest. The entire process—from screening to actual donation and rest—takes less than an hour but leaves a lasting impact. As Dr. Bhattacharya puts it, “It’s free, it’s safe, and it helps others while improving your own health. Why wait?”

With the constant rising temperatures, many people are worried about their health and wellbeing. Heat related illness have become the main source of concern for many people, as they look for better ways to navigate in the heat. Different countries have published heat guidelines to ensure citizens do not fall ill. It is very important to know the signs of and symptoms of these heat-illnesses as they could save your life!

One such symptom could be a major cause of concern. The National Health Services UK explains that people who are experiencing heatstroke need to be on alert. If the symptoms do not get better withing 30 minutes, you must call for help.

When to Seek Emergency Help

According to the NHS, if someone shows signs of heatstroke and is still unwell after 30 minutes of resting in a cool place, being cooled down, and drinking fluids, you should contact emergency services. While heat exhaustion often improves on its own within 30 minutes of cooling down, if it progresses to heatstroke, it becomes a medical emergency.

The NHS explicitly states: "Call 999 now if you or someone else have signs of heatstroke, including still [being] unwell after 30 minutes of resting in a cool place, being cooled and drinking fluids."

Heat Alert Issued for Parts of England

This week, the UK Health Security Agency (UKHSA) issued a yellow heat alert for certain areas of England, warning that even moderate temperatures could be dangerous. The Met Office predicts temperatures could reach up to 30°C in the East of England, East Midlands, London, and Southeast regions.

The UKHSA emphasized that "whilst temperatures may not seem too high for the general population for now, data from UKHSA shows that even at these forecasted temperatures, vulnerable groups and health care services can be impacted."

Under the UKHSA and Met Office's Weather-Health alerting system, a yellow alert indicates potential impacts such as:

• Increased demand on healthcare services from vulnerable groups.
• A higher health risk for individuals over 65 years old or those with existing health conditions, like respiratory and cardiovascular diseases.

Heat Exhaustion vs. Heatstroke

It's crucial to understand the difference between heat exhaustion and heatstroke, as the latter requires immediate emergency attention. Signs of Heat Exhaustion include:

• Tiredness
• Dizziness
• Headache
• Feeling sick or being sick
• Excessive sweating; skin may be pale and clammy or develop a heat rash (note: changes in skin color can be harder to see on brown and black skin)
• Cramps in the arms, legs, and stomach
• Fast breathing or heartbeat
• A high temperature
• Feeling very thirsty
• Weakness
• If these symptoms don't improve after 30 minutes of cooling down, it could be progressing to heatstroke.
• What to do for Heat Exhaustion (to prevent heatstroke)

If someone is suffering from heat exhaustion, immediately move them to a cool place and remove any unnecessary clothing, such as jackets or socks. Encourage them to drink a sports or rehydration drink, or simply cool water. To help lower their body temperature, cool their skin by spraying or sponging them with cool water and fanning them. You can also apply cold packs, wrapped in a cloth, to their armpits or neck.

To stay safe when it's hot, the UKHSA also recommends a few key things. Try to stay out of the sun between 11 am and 3 pm, which is usually the hottest part of the day. Keep your home cool by closing windows and curtains in rooms that face the sun. If you do go outside, cover up with appropriate clothing, a hat, and sunglasses, seek shade, and remember to apply sunscreen often. Plan any physical activities like exercise or walking your dog for cooler times, such as the early morning or evening.

Diet may seem like a secondary issue for many of us, but for athletes, it plays a very important role. The food they eat today could change the course of their game the next day. Athletes like tennis superstar Novak Djokovic have special diets that help them perform their best. Sharing the juices he drinks every morning in an interview; we get a glimpse of what goes into being a professional player.

Why Does A Diet Play An Important Role

Different sports require different types of diet, for example John Hopkins Medicine explains that a runner athlete must go for a carbohydrate rich diet as they must expend a lot of energy in an extended period of time, meaning they must sustain a uniform strain of energy to make sure they complete their run. On the other hand, judo or wrestler athletes must focus on a protein-based diet that will help them build muscles and strength.

For elite athletes, every little detail matters – from what they eat to how they train and recover. It can all make the difference between winning and losing. When it comes to fueling the body for success, Novak Djokovic stands out. With an astonishing 24 Grand Slam titles, he's the most successful male player in history, surpassing even legends like Rafael Nadal and Roger Federer, and he's still competing at the highest level.

What Does Novak Djokovic Eat?

Recently, in a TikTok clip with sports journalist Graham Bensinger, Djokovic revealed a surprising part of his daily morning routine. When asked about a typical day, he shared: "When I rise from bed, I start with warm water and lemon so I can help my body to detoxify and then I would have celery juice on an empty stomach." While this might sound a bit unusual to most people, Djokovic's drink choices are actually supported by some interesting science.

Science Behind the Sips

Warm lemon water is a fantastic natural source of Vitamin C. This vitamin is crucial for many bodily functions and significantly boosts your immune system. It's also a powerful antioxidant, helping to fight off harmful molecules called free radicals and keeping your cells healthy.

Drinking this first thing in the morning, as Djokovic does, can also be great for your digestive system. The Cleveland Clinic explains that it also helps us stay hydrated and is a great remedy for kidney stones, weight loss friendly, as well as filled with antioxidants like vitamin C, protecting your body from diseases.

Adding celery juice to the mix offers similar benefits. It's also rich in Vitamin C, along with Vitamins A and K, and essential nutrients like potassium, folate, and magnesium. For a tennis player like Djokovic, Vitamin K is especially important for strong bones, while the other nutrients help with muscle recovery and healthy blood flow.

Beyond the scientific benefits, Djokovic himself says these drinks give him mental clarity and a general feeling of energy, setting him up for a positive start to his day.

Even if you're not planning to follow the exact routine of a world-class athlete, staying hydrated is always a good idea. The NHS recommends drinking six to eight cups or glasses of fluid throughout the day.

Do We Need Detoxifying Juices?

As an addition to your diet, these can be helpful, however many people go on juice cleanses, relying solely on the juice for sustenance, which is not healthy for your body. A big selling point for juice cleansers is their supposed ability to "detoxify" your system. It's true that drinking more fluids can help your kidneys work better, and some nutrients can assist your body in getting rid of waste.

However, there isn't enough scientific evidence to show that juice cleanses or other "detox" diets actually improve your body's natural ability to remove toxins. Your liver and kidneys are incredibly efficient at detoxifying your body on their own, without the need for special juice regimens.
