The concept of the narcissistic pervert has invaded our screens and magazines in recent years. It's used a lot, but sometimes wrongly or without full understanding. So what is it really about?

No doubt you’ve heard at some point in your life that girls are more mature than boys. As a result, we tend to forgive childlike behaviour in men more easily, even in adulthood.

You may remember that we discussed the topic in...

Right from primary school age, we tell children that if another boy or girl has teased them, it’s “because they like them”. And playful teasing happens a lot in dating well into adulthood.

Warm summer nights often bring unwelcome guests into our homes in the form of mosquitoes. For now we fortunately don’t have any mosquito-borne diseases being transmitted to humans in the UK, but with the warmer temperatures brought on by climate change, it may only be a matter of time until that changes. You may have noticed that some of us seem to attract more mosquito bites than others, even wit...

Have you ever wondered how our expectations can impact the way we perceive and interact with others?

What many people don’t know though is whether sunscreen remains effective once it’s been opened, or whether using an out-of-date product is...

Back in 2015, 10,000 participants at Newcastle University’s Numbers Festival were asked what their favourite number was. Perhaps unsurprisingly, 12.6% of them answered the number seven, making it the most popular number of them all.

Getting restorative sleep and putting an end to back pain are both good reasons to opt for quality bedding. And if another reason was needed: on average, we spend 7-9 hours in bed every night and around a third of our lives sleeping in total. The problem is it can sometimes be like diving into a sea of options when it comes to mattresses. The most common type is the foam mattress, which adapts to...

In Japan, cleanliness is cultural and synonymous with well-being. That’s down in no small part to the influence of Shintoism, the country's oldest religion.
