    What is a tumour?
    Nov 17 2025
    What is a tumour? The word tumour comes directly from the Latin word for “swelling”. A tumour appears when a group of cells multiply and form a mass. Even though some tumours are malignant, or cancerous, most are actually benign, or non-cancerous. When normal cells multiply and remain localized, there’s nothing to worry about. These can be, for example, moles or warts. Can benign tumours develop anywhere in the body? What about malignant ones? How do you diagnose a malignant tumour? ⁠In under 3 minutes, we answer your questions!⁠ To listen to the last episodes, you can click here: ⁠What is intersectionality?⁠ ⁠What is Galentine's Day?⁠ ⁠What is Pokémon?⁠ A podcast written and realised by Joseph Chance.

  • Are blue eyes really more sensitive to light?

    Are blue eyes really more sensitive to light?
    Nov 17 2025
    The idea that light-colored eyes are generally more fragile is pretty widespread. They’re less resistant to sunlight and require more protection. According to Medical News Today, it’s estimated that around 8-10% of people in the world have blue eyes. When our eyes are open, rays of light pass through the pupil, the black opening in the center of the iris. As you may know, the pupil dilates when it’s dark and contracts in bright light. When light rays strike the retina, they’re captured by photoreceptor cells like rod cells, which are involved in night vision and cone cells that enable color vision, among other things. What’s the function of the iris ? Is sunlight dangerous for the eyes? Is wearing sunglasses enough to protect my eyes ? In under 3 minutes, we answer your questions!

  • How can I protect myself from winter viruses?

    How can I protect myself from winter viruses?
    Nov 17 2025
    During winter, we tend to huddle indoors in an understandable bid to stay warm. But while this makes for a cosy setting, it also becomes a major breeding ground for virus transmission. The dry air in offices, public transport and our homes can strip the moisture from our nasal passages, leaving us more susceptible to infections. The nose, mouth, and eyes serve as the primary gateways for viruses to enter the body. Unlike bacteria, which can be effectively combated with antibiotics, viruses thrive due to how hey siphon energy from host cells. When our initial immune response falls short, viruses infiltrate our bodies while our white blood cells kick into gear, producing antibodies. Do antibodies always do the trick? What about stomach bugs? In under 3 minutes, we answer your questions!

  • Can I prevent hair loss?

    Can I prevent hair loss?
    Nov 16 2025
    According to UK charity The Men’s Health Forum, two thirds of all men are affected by male pattern baldness in their lifetime. That won’t be a surprise to anyone, but would you have guessed that an estimated 50% of women also experience noticeable hair loss according to the Cleveland Clinic. We actually have around 100,000 hair follicles on our head, of which we lose between 50 and 100 every day, completely naturally. Hair loss isn’t usually any cause for real concern on its own, but of course it can be caused by cancer treatment. Even if a person’s health isn’t affected by their hair loss, It can still be an upsetting experience. Some types of hair loss are temporary. This can happen when a person has an iron deficiency, is stressed or loses weight suddenly due to a restrictive diet for example. Isn’t hair loss mostly hereditary? Are there any ways of stopping it? What about hair transplants? In under 3 minutes, we answer your questions!

    How can you save money on your food bill?
    Nov 16 2025
    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 at the checkout comes down largely to planning. Getting organised about how, when and where you buy your food as well as how you store and cook it is essential. For starters buying in bulk can really reduce costs. How can I reduce the amount I spend on food? How can I reduce my food waste? How can technology help?

  • Why does the cold make us need to pee?

    Why does the cold make us need to pee?
    Nov 16 2025
    We've all experienced it: the sudden urge to pee when it's cold is a common thing. This connection was supposedly discovered by Austrian physician Alfred Adler back in 1918. His experiment involved injecting cold water into a bladder to see how the body reacts. You might think it caused the kidneys to contract, but that's not the case... What did Adler discover then? Are there other factors explaining the link between the bladder and cold? What can you do if you struggle to hold it in?

  • Which foods will help you get a good night's sleep?

    Which foods will help you get a good night's sleep?
    Nov 15 2025
    Here at Do You Really Know, we’ve talked over and over again about the importance of getting good quality sleep. So of course, you don’t want your evening meal to disrupt it, and that’s a cause of uncertainty for many people. Bear in mind that to drift off to sleep, your body temperature needs to gradually drop. Given that digestion tends to raise our body temperature, that poses quite the conundrum. Now, the richer the meal or the heavier the food you eat, the longer it takes to be digested, which can lead to discomfort like reflux, heaviness, or bloating. I’ve often heard that a light dinner is best - is that a good starting point? So what kind of foods should we be aiming for then? What about drinks then? In under 3 minutes, we answer your questions!

  • Why do we get goosebumps?

    Why do we get goosebumps?
    Nov 15 2025
    The term goose bumps appeared way back in the 17th century, and describes the well-known phenomenon which shows up when we’re cold, scared or simply feeling strong emotions. For example, going out underdressed in winter, hearing the sound of fingernails on a chalkboard, or watching a horror film. Yes, indeed it can seem rather odd, but just like everything our bodies do, there’s a very logical explanation as to why they exist. Goosebumps are caused by the contraction of small muscles which are attached to our hair follicles. When that happens, hairs on our bodies are forced up, standing on their ends. The reflex is also known as piloerection. It makes our skin look like poultry, doesn’t it? What about these days? Can we control when goosebumps appear? In under 3 minutes, we answer your questions!
