Purple has been a dominant colour in our lives. Beyond those beautiful flowers, crayons, and candies, it is also often associated with royalty. Several kings and queens have been photographed wearing vibrant purple capes. As this colour continues to rule our environment, a new revelation about purple has left everyone shocked. Recently, scientists said that this colour does not exist in real life but is only a figment of our imagination.

Purple Has No Place In Electromagnetic Spectrum

Scientists have said that pruple doesn't exist, not in a way that we think. A new study has upended our perception of the colour wheel, revealing that purple is not a "real" colour in the spectral sense. Unlike red, orange, yellow, green, blue, and violet—which all correspond to specific wavelengths of light—purple has no unique place on the electromagnetic spectrum. Instead, it's a mental mashup, created by the brain to resolve a paradox it can't physically solve.

Here's What Actually Happens

When both red and blue wavelengths hit our eyes simultaneously—two ends of the visible light spectrum that should never naturally meet—the brain panics. Red and blue are like the North and South Poles of colour, never destined to blend in the linear sequence of light. simply bends the spectrum into a circle to make sense of the confusion. It fills in the gap by inventing a colour that doesn't technically exist in nature—voilà, we get purple. So purple is a colour that is technically not presen in the light spectrum, but exists as a solution to a problem.

Our Eyes Have Cone Cells For Colour Reception

To grasp why the illusion of purple occurs, we need to explore the biology of vision. Our eyes are equipped with three types of cone cells, each sensitive to short, medium, or long wavelengths—corresponding to blue, green, and red light, respectively. These cones transmit information to the brain through the optic nerve, where the thalamus and visual cortex analyse which cones were stimulated and to what extent.

This complex signalling system enables us to perceive not just basic colours but over a million distinct shades, including teal, magenta, and peach—each formed by combining inputs from various cones. However, purple disrupts this process. When both the short (blue/violet) and long (red) wavelength cones activate simultaneously without a corresponding spectral wavelength in between, the brain takes a creative leap. It invents a completely new colour. And this is how we get purple.

Purple Colour Has Psychological Effects

People often describe this colour as mysterious, spiritual, and imaginative. Meanwhile, psychologists associate the colour purple with the following aspects:

• Creativity
• Emotionality
• Enlightenment
• Femininity
• Imagination
• Inspiration
• Mystery
• Rarity
• Royalty
• Spirituality

“I remember waking up and feeling a strange numbness in one side of my face, I thought I slept wrong, but nothing could’ve prepared me for what I saw in the mirror that day.” Bobby followed a similar pattern of daily habits, wake up, finish the household duties, prepare the kids for their day, exercise and sleep as early as she can. However, worrying symptoms of facial paralysis were evident.

Being a homemaker, Bobby did not have out of the ordinary issues that could cause a disease contraction or sudden illness. “Upon visiting the doctor, we found out that this was a condition called ‘Bell’s Palsy’ a sudden and unexplained condition. As quickly as the symptoms showed up, we hoped the condition would also disappear, however that was a short-lived dream as it took months of physical therapy and medication to finally be rid of it.”

Bell palsy occurs when the muscles in one side of your face suddenly become weak or can't move at all. It usually starts quickly and can get worse within two days. This happens because the nerve in your face (called the facial nerve) gets damaged and you might feel pain or feel uncomfortable on that side of your face or head.

Bell palsy can affect anyone, no matter their age but it occurs more often among pregnant women and in people who have diabetes, flu, cold, or any other kind of sickness in their nose or throat. Men and women get it equally and it's not very common in kids younger than 15 or adults older than 60.

While you may not have heard of this disease, it is quite common. Dr. Siddharth Gautam, Neurosurgeon and a Member of Doctube, explains how approximately Bell’s palsy impacts approximately 15-30 people per 100,000 annually worldwide, in India. “In my neurosurgery practice, I see a significant number of cases each year, underscoring that this condition, while often overlooked in public awareness, is not uncommon.”

How Well Versed Are People With This Condition?

“In my experience, most patients are taken by surprise when diagnosed. Bell’s palsy typically presents abruptly, with rapid-onset, one-sided facial weakness or paralysis, often within hours” explained Dr. Gautam, he further explained how the change in their face can be deeply unsettling and causes people to take immediate steps. Other subtle signs include ear pain, altered taste, or facial tingling which could be early signs. However, people often mistake them as dental issues or ear problems, leading to delay in diagnosis.

Early Intervention Is Crucial For Bell Palsy Treatment

Dr. Gautum emphasized the need of early intervention, “Treating Bell’s palsy is the critical time window for intervention. Early initiation of corticosteroids, ideally within the first 72 hours, significantly improves outcomes.” He explained that people don't realize they have it quickly or wait too long to see a doctor, it can take longer to get better, and their face might not fully go back to normal. Also, it's important to help patients feel less worried and deal with how their face looks different, but this often doesn't get enough attentio

Symptoms of Bell’s Palsy

According to John Hopkins Medicine, bell palsy isn't usually something that stays forever but sometimes, in rare cases, it doesn't go away completely. Right now, doctors don't know how to cure Bell palsy. Most people start to get better within two weeks to six months after it starts, most people get all the strength and movement back in their face.

• Trouble moving face muscles for things like smiling, squinting, blinking, or closing your eye
• Headache
• Watery eye (tearing)
• Drooling
• Losing your sense of taste on the front part of your tongue
• Being extra sensitive to sounds in one ear
• Not being able to close one of your eyes

Can It Cause Long-Term Damage?

Bell palsy usually goes away over time without causing lasting issues. But it's important to take any medicine your doctor gives you. Protecting your eye from drying out is also key. Using eye drops during the day and ointment at night can help prevent scratches.

Bell palsy usually starts to get better in about two weeks. But it can take three to six months to go back to normal. Call your doctor if you don't get better, you have new symptoms, or your symptoms get worse.

What are the Risk Factors related to Bell Palsy?

Dr Gautum explains that there are some risks associated with bell’s palsy which include viral infections, diabetes, and hypertension. Another factor could be “pregnancy (especially in the third trimester), and recent upper respiratory infections. In my clinical practice, I also observe that stress and certain autoimmune conditions may predispose individuals to this condition, potentially affecting nerve function.”

While beauty routines are typically associated with self-care and health, a new study paints a shocking picture of what is possibly being stored in the bottles on our bathroom shelves. A recent study found in Environmental Science & Technology Letters finds that formaldehyde and formaldehyde-releasing preservatives, which are identified human carcinogens, are widely present in a vast array of beauty products used by women all over the world. And alarmingly, the people most affected are often unaware of the risks they face daily.

In a long-term observational study, Silent Spring Institute researchers monitored the at-home personal care practices of 70 Black and Latina women in Los Angeles for 5-7 days. The subjects provided ingredient lists and usage records for the products they used in the home and found the surprising trend: 53% of the subjects reported using products that had formaldehyde or formaldehyde-releasing agents present.

What Is Formaldehyde and Why Is It Used?

Formaldehyde is a pungent, colorless gas with broad use for its antimicrobial activity. In cosmetics, it is used as a preservative to increase shelf life and inhibit bacterial growth. But for all its useful purposes, it has a dark side: formaldehyde is a carcinogen according to several health organizations, including the U.S. National Toxicology Program and the International Agency for Research on Cancer.

Formaldehyde-releasing preservatives like DMDM hydantoin and quaternium-15 are also commonly substituted for formaldehyde. These chemicals gradually release small amounts of the chemical, offering continued protection against contamination—but possibly releasing cancer-causing agents with each use.

Among these products were:

• Shampoos and conditioners
• Body washes and lotions
• Eyeliner and eyelash adhesive
• Hand soaps and skin lighteners

One respondent used three formaldehyde-formulated products daily: a leave-in conditioner, a rinse-off conditioner, and a body wash. Others utilized hand soaps with formaldehyde agents several times daily—indicating repeated and consistent use.

Throughout the study, the 64 women used a total of 1,143 beauty products. Each woman, on average, applied 17 different products daily, with some applying as many as 43. This amount of exposure highlights the cumulative risk of toxic chemicals in daily regimens.

"Repeated exposures such as these can accumulate and do significant harm," explained Dr. Robin Dodson, senior author of the study. "It's not hair straightener anymore—it's everywhere that these chemicals are."

This problem doesn't impact all women the same. Black and Latina women are especially at risk because of socio-cultural and economic pressures that lead to conformity to Eurocentric beauty ideals. Regular use of chemical hair relaxers, skin lighteners, and other specialized products puts these communities at increased risk for health effects—such as breast, uterine, and ovarian cancers, which disproportionately impact Black women.

"This is all of the legacy and history of discrimination," said Black Women for Wellness co-author and executive director Janette Robinson Flint. "We shouldn't have to be chemists to know whether our products will make us ill."

Even though formaldehyde was designated a human carcinogen more than a decade ago, regulatory intervention in the United States has lagged and has been inadequate. The FDA had made plans in 2023 to propose prohibiting the use of formaldehyde in hair straighteners. However, two years down the line, no concrete action has been made.

Meanwhile, the European Union prohibited formaldehyde in cosmetics back in 2009. Formaldehyde and its releasing agents are also subject to strict labelling in the UK if found in concentrations above specific levels.

Several U.S. states, such as California and Washington, have introduced or implemented bills regulating these ingredients in cosmetics—but their efficacy is uncertain.

What to Watch for on Labels?

One of the biggest problems consumers have is that formaldehyde-releasing ingredients are not always labeled clearly. Rather than "formaldehyde," you might find chemical names such as:

• DMDM Hydantoin
• Imidazolidinyl Urea
• Diazolidinyl Urea
• Quaternium-15
• Bronopol

These are complicated and unfamiliar to most people, so it is difficult for consumers to make informed decisions.

Other Toxic Chemicals to Avoid

Formaldehyde is only one ingredient in the toxic mix in many personal care products. Other ingredients of concern include:

Benzophenone: A UV filter tied to hormone disruption

Parabens: Estrogen-mimicking preservatives tied to breast cancer

Hydroquinone: Skin-lightening agent prohibited in most countries

Triclosan: Antimicrobial now limited due to health and environmental issues

PPD (p-phenylenediamine): Hair dye ingredient tied to allergic reaction

Coal tar and mica: Identified irritants and possible carcinogens

Natural Alternatives for Your Beauty Routine

The best news is that you don't have to sacrifice safety for beauty. Here are detox tips for your beauty routine:

Go natural: Opt for products with fewer ingredients and familiar names. Ingredients such as shea butter, coconut oil, aloe vera, and beeswax are moisturizing and harmless.

Select certified clean brands: Opt for brands that have been certified by EWG Verified, USDA Organic, or those meeting EU cosmetic regulations.

DIY solutions: Consider homemade masks, scrubs, and hair oils using simple kitchen ingredients.

Shop small and local: Many indie brands are more transparent about their ingredient sourcing and often offer customizable, preservative-free products.

Stay informed: Use apps like Think Dirty or EWG’s Skin Deep to scan and evaluate products before purchase.

The responsibility for knowing what's in our products cannot rest with the average consumer alone. "We need real regulatory action to protect women," stated Dr. Dodson. "Reading labels isn't enough—we need bans on toxic ingredients."

Until now, awareness, education, and advocacy are the strongest defense. Your health is more valuable than any marketing slogan—read past the gloss and select beauty that doesn't have to come at the expense of well-being.

As per the World Health Organization (WHO), 57 million people had dementia worldwide in 2021. the Alzheimer's Disease International (ADI) predicted that this number will almost double every 20 years and reach 78 million in 2030. However, there is hope. An Indian origin researcher in the US developed a probiotic cocktail that will help prevent dementia.

What Is Dementia?

As per Alzheimer's Association, dementia is a general term for loss of memory, language, problem-solving and other thinking abilities that are severe enough to interfere with daily life. Alzheimer's is the most common cause of dementia.

It is an umbrella term for loss of memory and other thinking abilities that are severe enough to interfere with daily life. There are various types of dementia, including Alzheimer's, Vascular, Lewy body, Frontotemporal, other includes Huntington's and mixed dementia.

What Is Anti-Dementia Probiotic Cocktail?

The cocktail is developed by Hariom Yadav from the University of South Florida. It is one of a kind of blend of probiotics that can positively impact the microbiome.

Hariom Yadav, director of the USF Health Center for Microbiome Research and associate professor of Neurosurgery and Brain Repair at the USF Health Morsani College of Medicine, is leading the charge. As senior author of two recent studies, his work centers on how gut health affects the brain and cognitive function.

The microbiome is the unseen community of microorganisms that live by the trillions in a person's gut. This probiotic cocktail works by positively influencing the microbiome—the vast, invisible community of trillions of microorganisms living in our gut.

When the Gut Goes Wrong

In a healthy person, these microorganisms coexist in balance. However, when harmful bacteria and viruses disrupt this harmony, it can trigger systemic issues throughout the body. Research now links such disruptions to long-term brain conditions, including dementia and Alzheimer’s disease. This is particularly alarming as dementia cases are expected to double, reaching nearly a million new diagnoses annually by 2060.

Probiotic Cocktail Shows Promise

In a study published in Scientific Reports in January, Yadav’s team tested the cocktail, which combines multiple strains of beneficial gut bacteria. Unlike current Alzheimer’s treatments that focus solely on brain biology, this cocktail offers a new direction—targeting the gut to protect the brain.

Testing the Cocktail on Mice

To evaluate its effects, mice were given the probiotic blend in their drinking water for 16 weeks. They then completed a "water maze" test, which challenged them to find a hidden underwater platform using visual cues. Mice that consumed the cocktail consistently outperformed those that didn’t.

Positive Results in Brain Health

The researchers observed that the probiotic mixture reduced the accumulation of harmful brain proteins linked to plaque formation. It also appeared to decrease brain inflammation and maintain the integrity of the blood-brain barrier, preventing dangerous microorganisms from leaking into the brain.

A Synergistic Approach to Gut Health

“We actually developed this cocktail a few years back,” said Yadav. “Normally, people look at single-strain probiotics. But we discovered that when used together as a consortia, they have more power to shift the microbiome from harmful to beneficial.”
