2025/08/14

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,

Whether you're lounging on a beach, exploring a new city, or simply taking a break from your daily routine, finding ways to calm your mind while on holiday is really important for our mental and physical health. We often promise ourselves we’re going to disconnect from day one, but it's not as simple as that.

With inflation at the highest it’s been in 45 years, it’s no wonder people are looking for ways to manage their money more effectively. And the trend we’re talking about today has really taken off on Tiktok since the start of the year. The #cashstuffing hashtag had already reached 1 billion views on the platform at the time of recording. There’s actually nothing new about cash stuffing; in many ways it’s as if we were going back in time a few decades to when bank cards didn’t exist. It consists of

2025/08/13

If you ever meet a member of the royal family, you might be tempted to ask them for a selfie or an autograph but don’t be surprised if they politely decline. There are some good reasons why royals don’t take selfies or give autographs as well as a whole host of other rather unusual protocols that they must adhere to. Royals are often surrounded by crowds of people who want to see them or talk to them. Signing autographs or taking selfies could expose them to potential threats or harm. Also it

2025/08/13

Money can buy a lot, but can it buy happiness? This is a question that philosophers, economists, scientists and storytellers have puzzled over for some time; and if it can, then does more money make you even happier? According to Prof Jan-Emmanuel De Neve, director at the University of Oxford Wellbeing Research Centre there is a definite link between money and happiness, especially at the bottom of the pay scale. So for example someone earning £20,000 who moved to £40,000 would experience

Most of us have our smartphones on our person more or less all day, every day. Our photos, payment methods and a lot of personal data are stored on them. So we’re all wary of the risk of having them stolen when out in public. But did you know there’s another way someone can take control of your phone line without you even losing the device?

If you're not up to date with your vaccinations, it might just be time to schedule an appointment with your doctor! When it comes to the diseases we’re going to be talking about today, you could be forgiven for thinking they were a thing of the past, consigned to history. But believe it or not, some of them are making a comeback in the 21st century. Their resurgence can be partly explained by a false sense of security; basically we thought they were eradicated for good and let our guard down. As a

Ever since social media came along, dating trends have evolved constantly. They tend to reflect changes in society too. In previous episodes of Do You Really Know, we’ve talked about dawn dating, sneating and ghosting for example. There are so many different terms out there, and not all of them are positive.

We usually sneeze to protect ourselves from irritants such as pollen, dust, or chemicals. But there are some people who consistently sneeze when they look at the sun. In fact, this affects from 10 to 35% of us when we move from being in the shade to bright light, according to PBS.org. If it happens to you, perhaps you’ve been wondering if it’s an allergy to sunlight, but actually it isn’t. The reaction triggered by sudden exposure to light is called the photic sneeze reflex.

The world of cinema is full of films and sagas which leave their mark on a generation, sometimes becoming cult films. And another phenomenon is becoming more and more common: that of the spin off.

2025/08/10

When it comes to getting clean, some people prefer chilling in the bath for a good half an hour or more, while others like how quick and practical it is having a shower. Let’s consider the two choices from a health perspective. It's pretty common knowledge that taking a bath isn't very eco-friendly, in terms of water consumption.

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.
