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

‘How long do you think you will live?’, ‘Me? I’ll live till I’m 100 years old!’ As kids these answers were acceptable, full of life and energy, we believed that living till we are 100 was something that can be done. But as we age, we realize, not only is it a pipedream, but life stressors like food, cost of living and how healthy we actually are, can make 100 years sound like hell. Living a long life, like 80 or 70 years old is seen as a reasonable, achievable dream in comparison.

However, the reality of it is much more different than that. You are not being given a choice for a long life, you are paying for a long life with your health. So, if you were to be given a choice, it would be more like, live a perfectly healthy life till 50 or live a long life at the cost of it.

So, when we focus on our health, what should we aim for, long-term healthy years or longer years lived?

What is The Difference Between Life Expectancy And Healthy Life Expectancy?

According to the Royal Borough of Greenwich UK, Life Expectancy (at birth) is the average number of years a person is expected to live in a specific area, based on current death rates. It's a key statistic used to understand the overall health and well-being of a population.

The Life Expectancy gap measures the difference in this number. It can compare life expectancy between men and women or between different geographical areas, like towns or neighborhoods.

On the other hand, Healthy Life Expectancy (at birth) is a more specific measurement. It's the average number of years a person is expected to live in good health, without illness or disability, based on current health and death rates in a particular area.

Have We Been Living Healthier Or Longer?

According to Gov UK, Since the early 2000s, life expectancy has increased more than healthy life expectancy. This means the number of years people spend in poor health has also slightly increased. For example, men now live about 16.1 years in poor health, and women live about 19 years in poor health.

While women still live longer than men, the gap is getting smaller. The difference is now only 3.6 years. However, most of those extra years for women are spent in poor health. Women live 3.6 years longer than men, but they only have 0.7 years more in good health.

Do Older Adults Have Less Healthy Life Expectancy?

The same trend applies to people over 65. They are living longer, but they are also spending more of their later years in poor health. For instance, a 65-year-old man can expect to live an additional 18.8 years, but 8.2 of those years may be in poor health. For a 65-year-old woman, the numbers are 21.2 and 9.9 years, respectively.

This shows that while we're beating old age, we're not always beating the illnesses that come with it. The data suggests we are spending a smaller percentage of our early lives in poor health, but a larger percentage of our later years.

Can We Increase Our Healthy Life Expectancy?

According to the National Institute of Health, genes account for less than a third of your chance of living to age 85. The biggest factor is your behavior and lifestyle. By making healthy choices, most people have the potential to live to a very old age.

Living a healthy lifestyle has a huge impact on your well-being, especially as you get older. A long-term study of a religious group known for healthy living found that they live nearly 10 years longer on average than most Americans. Their secrets? Regular exercise, a vegetarian diet, avoiding tobacco and alcohol, and maintaining a healthy weight.

Experts agree that if you could only do one thing to live longer and healthier, it would be to exercise. Physical activity is crucial for staying active and avoiding disease and disability. Even small amounts of physical activity can help older adults. A study of adults aged 70 to 89 found that those who followed a moderate exercise program had fewer disabilities and recovered faster. A mix of walking, strength training, and balance exercises is especially effective.

Be skeptical of "anti-aging" products or quick fixes. The best and most proven path to a long and healthy life is through common sense habits and an active, engaged lifestyle.

It's a simple Monday morning, the sun’s up bright and early, the weather is pleasant, but the anxiety strikes me as soon as I open my eyes. It's the dreaded 10th grade Math exam, the one subject I never excelled at. As if it wasn’t enough that the exam could make or break whether I get enough overall grade to get into my dream schools, if I were to get a bad score on this, it would be a permanent mark on my record.

“I had studied enough, I can do this” I told myself, but what was the point my admit card was nowhere to be found. I searched high and low, my anxiety peaking with every passing minute. “I thought I got up in time? Why am I late, they’ll never let me into the exam hall” I could hear my heartbeat in my ears and it’s getting louder, louder and louder, until it's just a loud long noise. Next thing I know, I’m on my bed, I graduated 10th grade years ago and this was a dream.

What Do Stressful Dreams About School Say About You?

If it isn’t your school exam, then maybe your college entrance exam or perhaps a qualifying exam that could determine whether you get your dream job or not. Recurring dreams about school happen to a lot of us.

These dreams are very common. Experts suggest that they often appear when a person is feeling anxious in their waking life, especially about being evaluated or judged by a boss or another authority figure. These dreams can take many forms: a person might oversleep for an exam, be unable to find their classroom, study the wrong subject, or even show up to school without clothes. The dreams revisit a place where we first experienced success or failure based on our performance.

To understand this, one must know that dreams are a way for the mind to process memories and experiences, both conscious and unconscious. The school setting in these dreams is a stand-in for a feeling of being tested in life and worrying about not meeting other people’s expectations.

Why School is the Go-To Setting

The reason school so often appears as the setting for these anxiety dreams is because it’s where we first learn how to deal with life. Feelings of stress, inadequacy, and embarrassment often happen first in a school environment. These early experiences create foundational beliefs in our unconscious mind about how we handle pressure. For some people, these beliefs can be very hard to change, causing feelings of stress and worry to resurface years later in dreams, even if the beliefs aren't relevant to their adult life.

What Do Recurring Dreams Reveal About Us?

According to the Sleep Foundation, having a recurring dream—the same dream happening again and again—is a sign of an unresolved problem or a difficult emotion in a person’s life. These dreams may be a way for the mind to make sense of past experiences, or they might be a sort of practice run to help a person prepare for a threat or challenge they're facing in real life. The dreams are often a way for the mind to push a person to finally face and deal with a problem.

Another reason for a recurring dream is that it represents a basic psychological need that isn't being met. Experts say everyone needs to feel independent, feel capable, and feel connected to others. Some research has found that people who lack these feelings are more likely to have recurring nightmares with negative themes, such as failing, falling, or being attacked.

Can You Stop Recurring Dreams?

If you're bothered by having the same dream over and over, you can take some steps to try and make them stop. Experts recommend a few different approaches

• Address the root problem. If you can figure out what emotional problems or difficult feelings are causing your dreams, working through them may help the dreams stop.
• Consider therapy. A specific type of therapy called imagery rehearsal therapy is often recommended. With a therapist's guidance, you can practice reimagining the dream with a more positive ending.
• Reduce stress. Since negative recurring dreams are often linked to stress, finding ways to lower your stress levels may also help reduce the dreams.
• Prioritize mental health. People with mental health conditions like depression often have more negative recurring dreams. Treating these conditions can help reduce the frequency of bad dreams.
• Adopt healthy sleep habits. To get a better night's sleep, try to go to bed and wake up at the same time every day. It’s also a good idea to avoid caffeine, alcohol, nicotine, and fatty foods close to bedtime.
• Talk to your doctor about your medications. Some medications, including melatonin, can cause nightmares. Your doctor can advise you on whether changing the dose or stopping the medication might help.
• Treat sleep disorders. If you have a condition like insomnia or sleep apnea, getting treatment for it could help reduce how often you have negative recurring dreams.

At least once in our lives, most of us have dreamed of having a perfect memory. A brain that would remember crucial details at the nick of time, whether it is during your exam or an interview. But this is not just a dream, it is just another day for this young girl, who has a ‘Super Brain’.

Scientifically speaking, she has a very rare condition that makes her remember every detail of her life, like a record. In a 2024 interview by Official W5, Emily Nash, who was 18-year-old at the time of filming, from Ottawa, described her incredible ability to remember everything.

A Person Who Remembers Everything

The video explained how she is one of the few people in the world confirmed to have Highly Superior Autobiographical Memory (HSAM) She can remember the exact date and details of public events, from the death of Queen Elizabeth to celebrity news and movie release dates. Her memory is so precise that she can tell you what she was doing on a specific date, down to what she had for lunch and what was playing on the radio.

Her family even gave her the nickname "Wikipedia" because she was their go-to source for random facts and dates. Emily describes her memory as a "calendar" where each day is like a little movie she can rewind and fast-forward through.

How Is HSAM Different From Having Good Memory?

According to a 2024 study by Neuropsychology Review, HSAM is a very rare and special ability where a person can remember almost every single day of their life in incredible detail. If you give them a specific date, like "January 15, 2003," they can instantly recall what they were doing, what the weather was like, and even what they were wearing. Unlike memory athletes who use tricks to memorize things, people with HSAM do this automatically and without any effort. It feels like a movie playing in their mind. The review confirmed that HSAM is a truly unique type of memory.

It's Fast and Accurate

People with HSAM can recall memories quickly, with amazing detail, and the memories are almost always perfectly accurate.

It Doesn't Fade with Age

A person with HSAM who was studied at ages 75 and 80 still had an incredible memory, showing that this ability seems to resist the normal memory loss that comes with getting older.

It's Only for Personal Memories

The study found that people with HSAM are not better at remembering just anything. They are not smarter, and their memory for general facts, names, or things they learned in a textbook is normal—only their memory for their own life is special.

How Do People With HSAM Remember Everything?

The study explained what goes on inside the brains of people with HSAM.

Brain Activity

When people with HSAM recall a memory, their brain activity goes into overdrive. Areas that are normally used for memory light up much more intensely. This suggests that their memories are more vivid and that the brain's "memory network" is working at a much higher level.

Brain Structure

Interestingly, the physical structure of their brains doesn't appear to be bigger or different in size. Instead, the main difference is in the way certain brain regions are connected, particularly the hippocampus, which is a key part of the brain for memory. This suggests that the special memory isn't because of a bigger brain but because the brain's connections are wired differently.

How Does Researching HSAM Help Brain Health?

Understanding HSAM could be incredibly important for the future. By figuring out how these rare individuals remember so well, scientists might be able to develop new strategies to help people with memory problems, such as those caused by diseases like Alzheimer's. It could also help improve the accuracy of eyewitness testimony in legal cases. Ultimately, this research gives us a unique window into how memory works and how it might be strengthened.
