Do you really know?

It's back to school! Do You Really Know is dedicating a special week to sport. Because moving and doing regular physical activity is important for our physical and mental health! Listen again to our episodes about sport! With many types of personal goals, actually doing the task is only part of the battle. Being mentally prepared is also hugely important and can sometimes be overlooked. Sports and...

According to comparison website Finder.com, UK residents plan to spend an average of over £2100 on holidays abroad in the year 2023. Spending abroad has bounced back to pre-pandemic levels, having plummeted in 2020 and 2021, when travel restrictions were in place. Still, while many of us are making up for lost time when it comes to holidays, there’s also the small matter of a cost of living crisis...

Whether you’re going on a beach holiday, city break or camping trip, the chances are you’ll be soaking up the sun’s rays. Sunshine activates vitamin D production in the body, which has numerous benefits like protecting us from disease and improving mental health. But on the other hand, being exposed for too long can accelerate skin ageing. Excessive UV can even lead to skin cancer. According to th...

It’s worth bearing in mind that overtourism has become a real nuisance. As tourists, it’s not exactly fun being in a highly overcrowded area, but it’s even worse for the natural environment. Could tourism quotas be one way of addressing the problems? In mid-June 2022, the island of Corsica brought in quotas for three iconic sites: the Bavella needles, the Restonica valley and the Lavezzi islands....

As you may well know, astrology involves looking at the position of planets and stars when we were born, and using that to interpret their influence on our lives. Mercury happens to be one of the planets which is supposed to have the most influence and that’s particularly true when it’s in retrograde, which happens several times a year. Planets in our solar system orbit around the sun. If you thin...

Feta cheese is undoubtedly a star ingredient when it comes to summer salads. It goes without saying it plays a starring role in the Greek salad, but it can also add a savoury taste to other recipes like the watermelon salad for example. Feta is one of Kate Middleton’s favourites. But this summer feta isn’t only getting attention by featuring in salad recipes. It’s also made headlines in European p...

Each year, International Beer Day is celebrated on the first Friday of August. As you may know, beer is produced using only four ingredients: water, hops, malt and yeast, through a process called fermentation. Of course beer is harmful in excessive quantities, but don’t let that give you any misconceptions about fermented foods. Generally speaking, they play an important role in boosting gut healt...

What is trauma dumping, the toxic equivalent of oversharing? It’s common for good friends to tell each other about pretty much everything going on in their lives. Within healthy friendships, it’s a way of bonding and supporting one another, especially when one of the friends is struggling. But sometimes this goes drastically overboard, and someone shares something really personal and traumatic wit...

Some visitors can be so shocked by the reality of Paris compared to their expectations that they can experience psychiatric breakdowns or symptoms such as hallucinations, depersonalization, anxiety, dizziness and nausea. This is known as the Paris Syndrome. Romance, sophistication, croissants and sipping fine wine with the Eiffel Tower in the background spring to mind when thinking of a visit to P...

Voluntourism is the practice of volunteering one’s labour to a charitable cause in a developing country, in return for a soul-cleansing, perspective-changing, CV-bolstering experience. Perhaps a bit cynical? But with good reason.  Whilst it could be a mutually beneficial redistribution of wealth from the developed world to the developing, voluntourism harbours a dark and exploitative underwor...

According to a study published in the Journal of Thoracic Disease in 2015, 10% of all people are affected by obstructive sleep apnea. That figure rises for some population groups, like men, over-50s and overweight people.  It’s actually a mechanical disorder, rather than an illness. When we go to sleep, our muscles relax; that's totally normal. But when it comes to people affected by apnea, t...

Reaching carbon net zero by 2050 is one of the main objectives in the struggle against global warming. It’s also part of the Green New Deal the EU agreed upon in 2019. Since the start of 2022, many figures in agriculture have been pushing for a carbon farming policy which would see farmers rewarded for their efforts in sequestering carbon. It’s about using agricultural fields to store CO2 in the g...

To understand where white spots come from, we must first explain how nail growth works. If you’ve ever had white spots on your nails before, you may have been dismissively told that it's down to a lack of calcium or zinc. Basically, some mineral-deficiency. But this popular belief doesn’t really have any basis in fact. According to Healthline, nails grow an average of 3 millimeters per month. Thei...

If you drink alcohol, the chances are at some point you’ve had to deal with a nasty hangover, due to drinking too much. The associated headache, nausea, fatigue and other symptoms can make it a real challenge to get through the day after a night out.  There’s actually a scientific term for the unpleasant symptoms that come with a hangover; it’s veisalgia. According to Ted.com, between 3...

It’s been two years since we last discussed the Amazon on Do You Really Know, and even in that time, the outlook for the world’s largest tropical rainforest has worsened significantly. A report called “Amazonia against the Clock” was released in September, warning that the rainforest could reach a point of no return as soon as 2025. A study published in Nature Climate Change journal in March 2022...

Just like with body shaming or slut shaming, mom shaming is another example of how women are often subjected to disproportionate criticism, and made to feel guilty about their choices, in this case specifically about parenting methods. The term refers to how mothers are criticised or even humiliated, for the way they bring up their children and fulfil their role as a mother. Such comments often co...

In past episodes of Do You Really Know, we’ve talked about a number of Scandinavian lifestyle trends, like death cleaning and hygge for example. Both of those are inspired by similar sentiments; to do with feeling good in surroundings that aren’t overflowing with useless items. And yet, in recent months, we’ve been hearing more and more about a home decor trend that’s the complete opposite. Maxima...

Cellulite is a regular source of insecurity among women. That’s been especially true since women’s magazines came along, pretty much labelling it public enemy number one. In our collective minds, it’s become inextricably linked to being overweight or having gone through pregnancy. In reality, cellulite is the result of a number of factors, and hormonal changes in particular. The first thing to kno...

American psychiatrist Stephen B. Karpman coined this social model of human interaction in 1968. It describes the roles that we take on in unbalanced social relations. Relations which lead us to take one of three roles within Karpman’s triangle. These are three roles in Karpman's triangle. These are the victim, the persecutor and the saviour. And the role we take on unconsciously leads someone else...

When it comes to expressions about skin, the English language is not lacking. For example, we can be thick or thin skinned, or have someone under our skin. To show indifference, we say “it’s no skin off” our noses, and when we get excited we “jump out of” our skin.  The sheer number of different idioms reflects the deep links the skin has with our brains. Sometimes these links are visible and...

The cost of living crisis has seen food prices increase by as much as 65% according to the Office for National Statistics meaning that the average British household spends an extra £600 pounds a year on food. But considering that there is also about 4.5 million tonnes of food waste annually the possibility of reducing wasted food as well as bills has never been more needed. Reducing your bill...

On 29th October 2022, 20,000 people were celebrating Halloween in the Itaewon neighbourhood of Seoul in South Korea. One particularly narrow street became very overcrowded, and a huge crush ensued, leading to the deaths of 153 people, with many more injured. A month later, we still don’t know exactly what caused the crush.  One of the theories out there is that a rumour spread in the crowd, l...

Christmas festivities are coming and often go hand in hand with overindulgence, in the form of large servings of roast dinner, yummy pudding and alcohol consumption. That can result in heartburn, a condition which despite the terrifying sounding name, is usually relatively harmless.  It’s a burning sensation felt in the chest, behind the breastbone, which explains where the name comes from. B...

Surprising as it may seem, balance is more important than you might think. In September of 2022 the British Journal of Sports Medicine published the results of a ten year study which involved more than 1,700 middle-aged participants. They concluded that not being able to balance was associated with an almost twofold increase in risk of death.  Volunteers were asked to stand on one leg with th...

National Grid has warned of potential blackouts in the UK this winter, due to gas shortages. If it does happen, it would be the first time the country has seen controlled blackouts since the 1970s. The government has its Electricity Supply Emergency Code in place in case we end up in such a situation. The government plan sees rolling blackouts, with areas split into 18 different load blocks, each...
