How can I stop micro-awakenings from disrupting my sleep? Jan 16, 2026

Show notes

According to a Direct Line Group study from 2022, over 70% of UK adults don’t get the recommended 7-9 hours of sleep per night. Nighttime micro-awakenings are a common contributing problem.

For many of us, they happen four to six times per night without us even noticing. And they usually just mark the end of a sleep cycle. But they’re more common in some people, and can be down to various factors like anxiety, mental hyperactivity, asthma, acid reflux, or arthritis. The effects of caffeine, tea, alcohol, and tobacco should also be considered. And it’s important to know that as you age, your production of sleep hormone melatonin decreases.

How are our sleep cycles structured? What should I do if these micro-awakenings become too frequent? What if those techniques don’t work for me? In under 3 minutes, we answer your questions!

What Is Orthosomnia, this new sleep disorder? Jan 16, 2026

Show notes

Nearly one in three adults in the UK experiences symptoms of insomnia. On average, adults in the UK get about 7.6 hours of sleep per night. In recent years, the popularity of gadgets designed to track and improve sleep has surged. However, this growing focus on achieving perfect sleep has given rise to a new issue: orthosomnia.

Smartwatches, fitness trackers, and more advanced gadgets like connected sleep masks or mattress sensors track sleep patterns and stages, such as REM and deep sleep. According to The Guardian in October 2024, the sleep monitor industry was valued at 270 million pounds annually, reflecting the growing fascination with these detailed sleep metrics.

What is orthosomnia? Why do we think we need 8 hours of sleep? In under 3 minutes, we answer your questions!

Why do friend breakups hurt so much? Jan 16, 2026

Show notes

We all know that getting over romantic relationships can take time, sometimes weeks, months or years. Many poems, songs and film scenes have been dedicated to expressing the pain of dealing with such situations. But friendship heartbreaks don’t tend to get so much attention, even though they can hurt as much, or even more!

Well one of the main things is that there’s a template for ending a romantic relationship. It’s a rite of passage really. But that simply doesn’t exist when it comes to friendships. It’s way more blurry when it comes to pinpointing exactly how or when a friendship starts and ends. We kind of expect it to last forever, so it’s a shock to the system if it doesn’t. Most of us would struggle to know how to firmly but respectfully put an end to a friendship when we need to.

What are the main differences between these two types of breakup? What’s the best way to end a friendship then? In under 3 minutes, we answer your questions!

Can our bodies really catch up on lost sleep? Jan 15, 2026

Show notes

We talk about sleep needs a lot on Do You Really Know, so regular listeners will be well aware that we need 7-9 hours each day, and that not getting enough can lead to negative health impacts.

Regardless of who you are, when you get less than seven hours of sleep, you start accumulating what’s known as sleep debt or sleep deficit. The Sleep Foundation defines it as: “the difference between the amount of sleep someone needs and the amount they actually get.”

What can I do in the short term if I notice such symptoms? Can’t I just lie in on the weekend? So how can we make up for lost sleep without disrupting our biological clock? In under 3 minutes, we answer your questions!

How can I avoid always feeling hungry? Jan 15, 2026

Show notes

The feeling of hunger can be difficult to explain sometimes, especially if you feel like you've eaten as much as you usually do. As a result, we often end up either snacking or putting up with a rumbling tummy for hours on end.

Even if we manage to resist snacking, the risk is that when it gets to meal time we end up eating twice as much as usual! Feelings of hunger can also lead to a drop in energy or concentration problems. A number of factors can explain not feeling full after eating. One is not getting breakfast “right”. If you skip it completely, or eat something too sweet, that could well be why you get hungry later on.

What if I'm not hungry in the morning? What about at lunchtime? What should I do if even sticking to those guidelines, I still feel hungry? In under 3 minutes, we answer your questions!

Can jellyfish offer the key to immortality? Jan 15, 2026

Show notes

Throughout history people have been keen to find the answer to immortality. It's now commonly accepted that eternal life is not possible. Yet, somewhere deep in the ocean, a tiny fingernail-sized creature nicknamed the “immortal jellyfish” might be able to cast new light on the human aging process.

A new study published in August 2022 in the Proceedings of the National Academy of Sciences shows the results from a team of researchers who have mapped the jellyfish’s genetic code to find the secret to its immortality. They found that the immortal jellyfish has twice more copies of genes associated with DNA repair and protection than a regular jellyfish. They can produce greater amounts of protective and restorative proteins.

Why is the "immortal jellyfish" immortal? Will humans be able to regenerate like jellyfish? In under 3 minutes, we answer your questions!

Do aphrodisiacs really work? Jan 14, 2026

Show notes

You’ve no doubt heard that certain foods can increase desire, or even improve sexual performance. Oysters, ginger, chocolate and strawberries are just a few examples of foods that supposedly have that magical effect.

They’re labelled aphrodisiacs, a word which comes from the name of Aphrodite, the Greek goddess of love. There are very few scientific studies out there to back that belief up. In people who have blood circulation issues, some foods can have the same effect as Viagra, which relaxes the blood vessels and thereby improves blood flow to the genitals.

Can food really have an impact on our level of sexual desire? What about alcohol? So why do people keep talking about aphrodisiacs if they don’t really work? In under 3 minutes, we answer your questions!

Why are some people constantly sexually aroused? Jan 13, 2026

Show notes

The condition we’re going to talk about today is pretty rare. It affects around 1% of women, but it can really disrupt the lives of those who suffer from it. Persistent genital arousal disorder, or PGAD for short, was officially identified by the medical community back in 2001, when Sandra Leiblum and Sharon Nathan published an article about it in The Journal of Sex and Marital Therapy. At the time, they called it persistent genital arousal syndrome, and identified five specific criteria for diagnosis.

These were then expanded by the International Society for the Study of Women’s Sexual Health in 2021. According to that organisation, PGAD refers to “persistent or recurrent, unwanted or intrusive, distressing sensations of genital arousal”. It is “most commonly experienced in the clitoris but also in other genito-pelvic regions” and “may include other types of genito-pelvic dysesthesia” like buzzing, tingling, burning, twitching, itch or pain.” The minimum duration for a diagnosis is 3 months.

Show notes

You may know Hugh Jackman as the star of X-Men, The Greatest Showman, and Les Misérables, but did you know that he has a secret to success that involves working less, not more?

That’s right, Hugh Jackman follows the 85% rule, an unofficial guide to life that says we should try hard at things, but not too hard. In other words, we should aim to work at 85% of our capacity, rather than 100%.

But why would he do that, and does it really work? Does the science back up this claim? In under 3 minutes, we answer your questions!
