Hate and Love are deeply interlinked and the reason behind this is a brain chemical called Oxytocin. This hormone is the first element in the neurobiology of bonding and is an important driver in both care and prejudice.

Oxytocin, known as the love/cuddle hormone, is a chemical produced mainly in a small region of the brain called the Hypothalamus. It is then stored and released in the bloodstream by the pituitary gland. Oxytocin can impact social recognition, relationship formation, and long-term emotional attachment. Besides, it also helps in reducing blood pressure, which in turn, is beneficial for the heart. It also helps in lowering stress. There is empirical evidence to prove that oxytocin reduces the level of cortisol (stress hormone) in saliva.

So far so good. Right? Oxytocin promotes love, relationships and also benefits your health. But scientists say there is a dark side to this hormone too.

According to research published in Psychology Today, oxytocin promotes human ethnocentrism—the tendency to view one's group as centrally important and superior to other groups. Ethnocentrism creates intergroup bias that fuels prejudice, xenophobia, and intergroup violence. Additionally, oxytocin also enhances envy and gloating in a social game.

"Grounded in the idea that ethnocentrism also facilitates within-group trust, cooperation, and co-ordination, we conjecture that ethnocentrism may be modulated by brain oxytocin, a peptide shown to promote co-operation among in-group members. Results of the study show that oxytocin creates intergroup bias because oxytocin motivates in-group favouritism and, to a lesser extent, out-group derogation. These findings call into question the view of oxytocin as an indiscriminate "love drug" or "cuddle chemical" and suggest that oxytocin has a role in the emergence of intergroup conflict and violence," researchers said.

How Is Oxytocin Released?

Oxytocin is one of the few hormones that have a positive feedback loop. This means that releasing oxytocin leads to actions that stimulate your pituitary gland to release even more of it. Most hormones, like dopamine and serotonin, create negative feedback loops after they are released, meaning your body releases less of the hormone after it has its effect on your body.

If you have a low Oxytocin level, which is a rare condition, then it could stop uterine contractions during the birthing process and prevent milk ejection after giving birth. On the other hand, if you have levels of this hormone, it results in an overactive uterus, causing an increase in uterine muscle mass. This limits pregnancy due to not having enough space in your uterus to hold your fetus.

If you’ve been coughing for weeks, blaming it on “lingering winter sniffles” or chalking it up to “just getting older,” it might be time to step away from the cough syrup and lean in for some uncomfortable truth. Your cough could be more than a seasonal annoyance. In rare but serious cases, it could be a red flag for a life-limiting condition called pulmonary fibrosis.

What is Pulmonary Fibrosis?

In plain terms, “pulmonary” means lungs, and “fibrosis” means scarring. It’s a serious, progressive condition where lung tissue becomes scarred and stiff, making it increasingly hard to breathe.

Reportedly, there’s currently no cure. Treatments exist, but they mainly slow down the damage rather than reverse it. The sooner you get diagnosed, the better your chances of managing symptoms and that’s where spotting the signs early is crucial.

Symptoms to Watch For

Shortness of breath (especially when climbing stairs or speed-walking to catch the bus)

Why That Cough Happens

Coughing is your body’s bouncer, booting out anything that might harm your lungs — dust, smoke, rogue crumbs, the works. The process involves your vocal cords clamping shut, then snapping open with a burst of air.

With pulmonary fibrosis, this reflex can get stuck on a loop. Coughing irritates the vocal cords, which makes you cough more, which irritates them further, a vicious cycle that can turn even a quiet cup of tea into a coughing fit.

The Four Flavours of Cough

Acute cough – Lasts less than three weeks; often tied to infections or irritants.

Coughs can also be:

Dry/unproductive – Triggered by things like temperature changes, dusty air, or laughing.

Who’s More at Risk?

While pulmonary fibrosis can happen to anyone, your risk might be higher if you:

Are over 50

Managing the Cough

A pulmonary fibrosis cough often doesn’t respond to standard cough medicines. Instead, treatment usually focuses on easing symptoms and improving quality of life.

Your doc may recommend alternative medications used for chronic cough in other conditions. These don’t cure the scarring but can make the coughing less intrusive. They’ll also want to check for other contributing factors like acid reflux, sinus issues, or side effects from medication, because if those are making things worse, tackling them can help.

Everyday Coping Tricks

While you work with your doctor, you can try a few lifestyle tweaks to manage coughing fits:

Avoid smoky, dusty, or heavily polluted spaces

Pulmonary fibrosis is rare, but catching it early can mean more treatment options and better management. Plus, you’ll finally know whether your cough is from a stubborn cold or something that needs closer attention. Your cough could be a harmless side effect of a dusty ceiling fan or it could be your body waving a red flag.

If you’ve ever stared at a packet of mixed nuts wondering whether to sprinkle them over your porridge or just eat them by the handful, here’s your permission slip: go for it. According to Dr Sarah Berry, a professor at King’s College London and Chief Scientist at ZOE, nuts and seeds are not just snackable; they are good for cholesterol crunching. In fact, swap some of your less healthy fats for these nutritional powerhouses, and you could lower your cholesterol by up to 10 per cent in just 10 days. That is faster than most fad diets.

The 10-Day Cholesterol Challenge

High cholesterol often feels like one of those invisible problems, until it suddenly is not. It can quietly build up in your arteries, increasing the risk of heart attacks and strokes. But Dr Berry, during an appearance on the Zoe podcast, said that you can make a real difference in under two weeks by tweaking, not overhauling, your diet. It’s not about eating less fat; it’s about eating the right kind of fat.

And this is where most people get it wrong. “Don’t do a low-fat diet,” Dr Berry warns, calling the idea “radical” to anyone still following decades-old advice. Instead, aim for a moderate-fat diet rich in polyunsaturated and monounsaturated fats—exactly the kinds you’ll find in nuts, seeds, and certain oils.

Why Low-Fat Diets Miss the Point

It is tempting to think cutting fat will cut cholesterol, but Dr Berry explains that’s a trap. Not all fats are bad. Saturated fats, found in red meat and some processed foods, can push LDL cholesterol—often dubbed “bad” cholesterol—into dangerous territory. But polyunsaturated fats, abundant in seeds, seed oils, and many nuts, do the opposite.

Simply adding nuts to your meals, whether as a snack, salad topping, or nut butter, can slash LDL cholesterol by 5 to 10 per cent. You have to make a swap. This benefit comes from replacing “harmful” fats, like those in certain animal products and fried foods, with healthier plant-based fats.

Seeds: The Cholesterol Fighters

Sunflower seeds, flaxseeds, chia seeds—they’re all loaded with polyunsaturated fatty acids that support heart health. Stir them into yoghurt, blend them into smoothies, or scatter them over roasted veggies. You’ll barely notice the extra effort, but your arteries will thank you.

Seed oils, like sunflower and flaxseed oil, can also be smart choices in moderation, adding healthy fats to your cooking without the cholesterol-raising impact of certain animal fats.

Rethinking Dairy, Meat, and Carbs

Dr Berry isn’t out to demonise all animal products. Fermented dairy like yoghurt and cheese gets a surprising green light. These foods, she says, don’t have the cholesterol-raising effect you might expect from their saturated fat content. That’s not permission to live on brie and cheddar, but it is a reason to stop fearing your cheese board.

Red meat, however, is a different story. Packed with saturated fats, it’s a direct contributor to rising cholesterol levels. Swapping steak nights for lentil stews or chickpea curries a couple of times a week could make a noticeable difference to your numbers.

Then there’s the carbohydrate conundrum. The real trouble lies with refined carbs like white bread, white rice, and sugary snacks. These are rapidly processed by your body and can be converted into triglycerides, which worsen cholesterol profiles. But whole grains are firmly in the “good for you” column. Wholegrain bread, brown rice, oats, and quinoa can help improve cholesterol levels when they replace the refined stuff.

Building Your 10-Day Cholesterol Menu

Swap your morning white toast for porridge topped with walnuts and chia seeds. Your mid-morning biscuit could become a small handful of almonds. At lunch, toss sunflower seeds into your salad, and use olive or sunflower oil for dressing. Dinner might feature grilled salmon or chickpeas instead of steak, with a side of quinoa instead of white rice.

Why This Works So Fast

Cholesterol levels can be surprisingly responsive to dietary changes. LDL cholesterol particles are constantly being produced and cleared from your bloodstream. When you replace saturated fats with healthier fats, you improve your body’s ability to remove LDL cholesterol. Combine that with reducing refined carbs and upping your wholegrain intake, and the improvement can be measurable in just days.

Dr Berry’s advice is refreshingly realistic: no calorie counting, no extreme restrictions, just sensible swaps. It’s about building habits you can maintain beyond the initial 10 days, keeping your cholesterol low for the long haul.

Forget the idea that lowering cholesterol means bland food and joyless salads. With nuts, seeds, and the right fats, you can eat deliciously and still give your heart a health boost in record time.

You walk out of the tattoo studio with fresh ink that looks bold, bright, and perfect. But within a few days, you notice the colours seem duller, almost blurred. Do not worry! This cloudy look is a normal part of healing. According to dermatologists and tattoo artists, that milky veil over your design is not the end of your tattoo dreams. It is simply your skin doing its job.

The Science of the Skin Screen

As Dr Pragati Gogia Jain, DNB (Dermatology) at ApolloMedics Hospital, Lucknow, explains, our skin has layers. The top layer, called the epidermis, is made up of keratinocytes. When these cells are young, they’re packed with organelles and nuclei, making them opaque. As they mature, they lose these structures, becoming more transparent.

When you get a tattoo, the needle bypasses the epidermis and deposits pigment in the dermis. This process causes a controlled injury, triggering inflammation. In the days that follow, damaged keratinocytes in the epidermis start shedding (desquamation), and the fresh replacements are immature and cloudy.

“This cloudy layer scatters light, making the tattoo look dull,” says Dr Jain. “It’s temporary, and as the epidermis completes its 28-day turnover cycle, your tattoo will regain its clarity.”

What’s Happening Beneath the Tattoo Ink

Sahil Bali, tattoo artist at Devil’z Tattooz, says the fresh-out-of-the-studio vibrancy is like an Instagram filter: beautiful, but fleeting. “Right after we finish, the ink is just beneath intact skin, so the colours look sharp,” he says. “But as your immune system gets to work, a thin layer of scabbing or peeling skin forms. It’s made of dried plasma, old skin flakes, and natural oils, which aren’t transparent.”

This layer dulls the appearance of the tattoo. From day four to day ten, peeling starts. The temptation to pick at those flakes is real, but doing so can yank out pigment and cause patchy healing. “Hands off is the golden rule,” warns Bali.

Why Tattoo Aftercare Matters

While most cloudiness is part of the healing process, poor aftercare can make it worse. Dr Jain says that slathering on too much ointment can trap moisture between skin layers, creating a hazy effect. Over-moisturising can also make the peeling phase messy, while under-moisturising can slow healing.

The golden trio of aftercare:

• Keep it clean, but not soaking wet
• Moisturise lightly with fragrance-free ointment or lotion
• Avoid scratching, picking, or exfoliating the area until it’s fully healed

The Healing Timeline: What to Expect

• Week 1: Swelling and inflammation can make colours look slightly different. Cloudiness starts to creep in.
• Week 2: Peeling is in full swing, and the haze is most noticeable. Do not pick.
• Weeks 3–4: New skin settles in, clarity returns, and your tattoo looks almost like day one.
• Weeks 4–6: Full healing. Your tattoo now has its true colours and crisp lines.

Your tattoo’s journey is a cycle: vibrant due to fresh ink, hazy during inflammation and peeling, then clear again as the skin regenerates. In short:

• The cloudy phase is temporary.
• Don’t touch, scratch, or peel.
• Follow optimal aftercare to prevent infection.
• Always ensure your artist uses fresh, sterilised needles.

As Bali puts it, “Your tattoo is for life. A couple of hazy weeks is nothing compared to years of wearing a clear, beautiful design.”
