Heatstroke is a medical emergency that happens when your body temperature gets too high and you cannot cool down. This can harm your vital organs and even kill you if not treated quickly.

Heatstroke can be caused by being exposed to high temperatures, such as during a heatwave, or by working out too hard, such as during a marathon. It is different from heat exhaustion, which is a less severe condition that can lead to heatstroke if not treated.

What are the four types of attachment in our relationships? Jan 20, 2026

Show notes

The types of attachment were theorized by British psychologist John Bowlby in the 1950s. They are widely used to help us understand how we react to situations in our relationships, whether it be with romantic partners, friends or family members.

Bowlby relied on research on the impact of early separations between infants and their mothers, and emphasized the importance of attachment relationships in the social and emotional development of children, as well as their long-term mental health.

What exactly is an attachment style? And what about the other two types? In under 3 minutes, we answer your questions !

What is Blue Monday? Jan 19, 2026

Show notes

Sorry to end the week with bad news but tomorrow, January 16th, is Blue Monday, often cited as the most depressing day of the year. Blue Monday has existed since 2005, and is based on an equation which takes into account various factors. However, its detractors criticise the idea as pseudoscience and say it is driven by money.

Since the first Blue Monday equation was devised by psychologist Cliff Arnall, there have been a few different variants, but there are common elements to each. Of course you’ve got the winter weather, which explains why Blue Monday isn’t a phenomenon in the southern Hemisphere, where January is a summer month. Blue Monday is also not well known in the United States, as it usually clashes with Martin Luther King Day.

Why does Blue Monday occur in January? Black Friday, Super Saturday, Blue Monday - why do I get the feeling this is just another marketing thing? Is there any scientific evidence backing Blue Monday ? In under 3 minutes, we answer your questions!

Which colours go well together according to science? Jan 19, 2026

Show notes

It's often said that colour preferences are simply a matter of personal taste, but actually some have been backed up by science, especially in the field of art history. For the last two centuries, it has been customary in art and design to come up with colour combinations based on what is known the colour wheel.

It’s a visual representation of the spectrum of colors, organized in a circular format. This wheel divides colours into primary: red, blue, and yellow, secondary: green, orange, and purple, and tertiary colors, creating a harmonious spectrum.

But what is it? Where does it come from? What’s the point of it? In under 3 minutes, we answer your questions!

What is the Smurfette Principle? Jan 18, 2026

Show notes

Does that ring a bell? How many of you spent hours in front of the Smurfs as children? We’re sure you remember the smiley little girl with blond hair, a white dress and high heels.

In case your memory has faded, in the wonderful world of the Smurfs, Smurfette is created by the evil wizard Gargamel to sow discord! How curious that the role of agitator is reserved for a female character... Add to that the fact that the Smurfville population is exclusively male, until the arrival of the lone Smurfette. That’s where the idea of the Smurfette Principle comes from. It’s mainly to do with the overrepresentation of male figures as protagonists in works of fiction, to the detriment of female characters.

How can you base a whole theory on a single cartoon? What’s wrong with that? It’s fiction after all and fiction can write its own rules, can’t it? In under 3 minutes, we answer your questions!

Could the 42% rule help me have a better work-life balance? Jan 18, 2026

Show notes

More and more people across the world are struggling with burnout. According to a Future Forum survey of over 10,000 workers from February 2023, as many as 42% of workers experience it, an all-time high. When signs of exhaustion emerge, the ideal solution is, of course, total rest, but it's often a luxury that few can afford. An alternative for preventing burnout is what's known as the "42% rule."

The rule was introduced in 2019 in a book authored by two identical twins from the USA: Amelia and Emily Nagoski. The book was entitled "Burnout: The secret to solving the stress cycle" and it was based on the sisters' personal experiences.

Does olive oil really make you fat? Jan 17, 2026

Show notes

Olive oil, a cornerstone of the Mediterranean diet, boasts a rich composition of essential fatty acids, vitamins A, D, E, and K, along with polyphenols. These antioxidants are celebrated for their role in decelerating cellular ageing. Fatty acids, a pivotal component of lipids, include some that our bodies cannot produce, underscoring the necessity of sourcing them from our diets.

Predominantly composed of omega-9, olive oil’s monounsaturated fatty acids are linked to a diminished risk of cardiovascular ailments. They are also known to lower LDL-cholesterol—the infamous ‘bad’ cholesterol—as well as the overall cholesterol levels in our bloodstream. Additionally, olive oil serves as a natural appetite suppressant, fostering a sense of fullness and aiding in the regulation of blood sugar levels.

Does all this mean that olive oil is calorie-free? How do I choose the right oil? And how do you store olive oil properly? In under 3 minutes, we answer your questions!

Which conspiracy theories were actually true? Jan 17, 2026

Show notes

The origins of Covid-19 still remain somewhat hazy, over three-and-a-half years since the virus began spreading across the world. That has led to a number of prominent conspiracy theories, with 25% of people in the UK believing that Covid was definitely or probably a hoax.

That finding was part of an April 2023 survey by Savanta for King’s College London and the BBC. It also established that belief in other conspiracy theories is relatively high too, like the idea that the cost of living crisis is a government plot to control the public. Of course, the vast majority of them are false, but there are certain exceptions to the rule.
