Do you really know?

Back in 2015, 10,000 participants at Newcastle University’s Numbers Festival were asked what their favourite number was. Perhaps unsurprisingly, 12.6% of them answered the number seven, making it the most popular number of them all. Some said they didn't know why they chose seven, but as you know, the number tends to have positive connotations and is associated with luck in particular. That’s espe...

A comfy mattress, be it firm or soft, and a good pillow are all essential for a good night’s sleep but increasingly people are also buying weighted blankets to help them relax. A weighted blanket is exactly what it sounds like, a blanket that is heavier than your usual duvet. They are normally filled with either plastic pellets or glass beads and their extra weight is designed to provide a light p...

Climate refugees, or climate migrants, are people forced away from their homes due to sudden or gradual alterations in their natural environment. We’re talking about sea-level rise, extreme weather events, drought and water scarcity for example. They are also referred to as displaced people. According to a report by the European Commission on Migration, each year, an average of 30 million people a...

According to research published in The BMJ in 2002, around 40% of people experience some age-associated memory impairment after reaching 65. Thankfully only 1% of those affected will then go on to have dementia each year. But still, it’s important to be aware of how effective your memory is, whatever your age. An impairment can be a sign of cognitive decline, which becomes more likely the older we...

Because moving and doing regular physical activity is important for our physical and mental health! Listen again to our episodes about sport! After an intense and sweaty workout, the first thing most of us want to do is jump into the shower to relax our muscles and wash off the sweat. However, that’s not actually the best idea. Showering too soon after a workout can have harmful effects on our hea...

We all know about the physical consequences of having an unbalanced diet, and one that includes a lot of junk food in particular. In the short term eating lots of it can lead a person to put on weight and see their blood pressure increase, while it can also potentially lead to long-term conditions like diabetes or heart disease. But studies are increasingly clear on the fact that junk food can als...

Have you ever felt tiny when contemplating the vast, 14-billion-year-old universe? Maybe you’ve wondered, “Is there another form of intelligence out there, pondering the same questions I am?” This thought often leads to another: “If the universe is infinite, there must be other forms of life! So why don’t we have any proof?”  Congratulations, you’ve just stumbled upon the Fermi Paradox! What is th...

If your partner is constantly snoring, hogging the blanket, or tossing and turning every five minutes, and you're finding it increasingly challenging to share a bed, know that you're not alone. A 2017 study revealed that while 50% of those surveyed claim to sleep as a couple, 41% prefer solo slumber, and 54% feel sleep-deprived. There are some tricks to make co-sleeping more manageable. First off,...

Whether it's a reflex, a craving, or a belief in its necessity, people often find themselves snacking more in winter, or opting for heartier meals than usual. And it's been backed up by scientific studies. For example, a 2006 Massachusetts study found that we eat an average of 86 more calories per day in winter. And While it's true that colder temperatures make us burn more calories, the differenc...

“Good manners and bad breath get you nowhere”, sang Elvis Costello in his 1981 hit New Lace Sleeves. And it’s true that halitosis, the scientific term for bad breath, can become a real source of shame and embarrassment when you realise or suspect you have it.  What’s more, brushing your teeth properly twice a day won’t necessarily stop it from happening to you. And neither will the chewing gum, mi...

Of course regular alcohol consumption doesn’t always kill, but it can lead to other health problems, including neurological disorders. Wernicke-Korsakoff Syndrome is one such...

You might not be familiar with the term ‘kinkeeping’, but the chances are you’ve benefited from it at some point in your life, in particular as a child but also in adulthood if you’re a man. It refers to the household or family tasks that are subconsciously assigned to women due to their gender. Of course, it’s pretty much equivalent to unpaid labour, and a lot of the time is taken for granted, go...

"There are way easier places to work, but nobody ever changed the world on 40 hours a week." That’s exactly what Elon Musk tweeted in November 2018, as part of a call for new talent to join his companies. The post went viral, leading to a lot of people critiquing Musk's take on work and merit. Despite the criticism he faced, a lot of people, and followers of hustle culture in particular, stood fir...

The perineum is a group of muscles that works like a hammock, stretching from the pubic bone to the tailbone. To pinpoint its location, try coughing; you’ll feel a downward pressure in your lower abdomen.   It provides support for your internal organs, like the rectum and bladder, and for women, the vagina and uterus. It also absorbs physical impact. For example, when you run, the increased abdomi...

The chances are that at some point you’ve scoured the internet in an attempt to figure out why you’re feeling sick. Maybe you go to Dr Google as a matter of habit any time you’re in discomfort or pain. Indeed, back in 2019, Google Heatlh Vice President David Feinberg told the Telegraph that 7% of all Google searches related to health, adding up to an incredible 70,000 every minute. But there are d...

This annual celebration of love and passion needs no introduction. Among those who partake in Valentine's Day, you’ve got those who go all out every year, never failing to honour the occasion and make sure everyone knows about it.

Love is without doubt one of the most fascinating and elusive topics in human psychology. You might have wondered at some point just what it is that makes romantic relationships work, and whether there are objective criteria that help.  As we delve into the realm of human emotions and relationships, let’s discuss the Triangular Theory of Love. It was proposed by American psychologist Robert Sternb...

Most of us never really forget the person who first made our heart race or that awkward, wonderful, or maybe disappointing teenage kiss. Whether it was magic or a mess, that first experience often leaves a mark that shapes the way we see relationships as adults. How can one relationship have such a lasting effect?
So, do we keep comparing every relationship to that first one?
Does it matter if tha...

You might or might not  be surprised to learn that warm weather naturally enhances the libido. According to a 2022 survey by the Kinsey Institute, 60% of Americans report that spring is the season when they most want to get under the duvet with their partner.  It all comes down to hormones. Light and warmth naturally stimulates our serotonin production, a mood-enhancing chemical. Additionally, it...

Whether it starts over a sock left on the floor or a political debate that erupts a little too early at the holiday table, conflict is part of life. It’s not that we argue all the time,  it’s that these moments stick with us. Sometimes they clear the air and help us grow; sometimes they shut us down and leave resentment simmering for years. So it’s worth knowing how to argue well. What actually ma...

Feeling disconnected from a partner is a common problem in romantic relationships. According to a survey by McCain Foods in 2018, it affects 60% of all people in a relationship. Even worse, 15% of respondents admitted to spending more time interacting with celebrities on social media than with their partner.  This sense of disconnection often stems from a lack of communication within the relations...

When someone tells you not to do something it often becomes even more tempting, which is why, as a teenager, when your parents forbade you from seeing a certain boyfriend or girlfriend you felt even more passionate about them. Now psychologist have looked into what causes this so-called  ‘Romeo and Juliet effect’. Psychologists at the University of Colorado chose the name of Shakespeare's play fol...

It’s a quiet Sunday evening, and you’re scrolling through Tinder, swiping left and right. Unlike the endless upward scroll of social networks, Tinder feels more like a slot machine. Swipe, swipe, and then — ding ! A match. A new game begins. But will this match lead to a true love story? Probably not. And that’s the crux of what digital scientist Aurélie Jean calls the Tinder paradox. Aurélie Jean...

Looking for love in this day and age can be a time-consuming and draining process. More often than not, it involves downloading one or more dating apps, swiping through profile after profile, chatting for a while and then finally actually meeting up if it gets that far. It can feel like a bit of a crap shoot, and when things don’t lead anywhere, that can be disheartening. Well, a trend called date...

Retinol works by stimulating the production of collagen, which is the protein that gives your skin strength and structure, and by speeding up the turnover of skin cells, which means it helps remove old cells from the su...
