In the context of mental health, a phobia is far more serious than a mild aversion.
Many of us dislike flying, or giving a talk in front of our colleagues, and we might not be too happy if a large, slobbery dog, no matter how gentle, came bounding toward us. But as long as we can tolerate these kinds of situations without too much distress, and our lives aren't adversely affected, then we haven't got a phobia for any of these situations as such.
In contrast, people diagnosed with a relevant phobia would experience an intense, extremely unpleasant fear reaction that could be overwhelming. So much so, that it might interfere with their day-to-day lives. Flying phobias, social phobias, and a fear of dogs (even cute ones) are common examples - but there are dozens of others, including some quite bizarre examples, such as trypophobia, which is a fear of clusters of holes (like you get in crumpets), sedatephobia (a fear of silence) and gerascophobia (a fear of ageing).
ARE PHOBIAS A DISORDER?
Phobias are a formal psychiatric diagnosis in the anxiety category. To be diagnosed, you'd need to have experienced a phobia for at least six months, and your fear reactions to the focus of your phobia would need to be out of proportion to the danger you were in.
Psychiatry recognises five main categories of 'specific phobia' (between 3 to 15 per cent of people will develop one of these at some point in their lives): animal phobias (spiders and snakes are common examples); environmental phobias (such as heights or deep water); blood/injection phobias (think needles or the mere sight of blood); situational phobias (such as bridges or dentists); and finally an 'other' category that covers almost everything else, such as a fear of swallowing or being sick.

COULD MARINE CLOUD BRIGHTENING HELP US FIGHT CLIMATE CHANGE?
The theory behind marine cloud brightening is that brighter or whiter clouds reflect more sunlight back into space.
IS IT SAFE TO RUN EVERY DAY, OR SHOULD I DITCH MY RUN STREAK TO SAVE MY KNEES?
A running streak, where you run every day without taking rest days, can be highly motivating and beneficial for overall fitness. Running is great cardiovascular exercise and isn't to be discouraged (and finding a routine with some consistency is great). Getting a bit of exercise as often as possible is also hugely beneficial for your mental health.
WHAT MAKES THE MEDITERRANEAN DIET SO GOOD FOR US?
The Mediterranean diet may help you live longer, especially if you also adopt the lifestyle of people living near the Med during the 1950s.
WHAT IS MEXICO'S BLUE HOLE?
The world's deepest blue hole (marine sinkhole) lies off the coast of Mexico's Yucatán Peninsula. It's at least 420m (1,378ft) deep, but explorers still haven't found its bottom.
HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?
Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys. It plays a critical role in various bodily functions, including regulating metabolism, reducing inflammation and helping the body respond to stress. While essential for our health, chronic elevation of cortisol levels can lead to several issues.
THE LUNGFISH
In 1836, European scientists discovered a peculiar animal from the River Amazon that they struggled to identify. Its eel-like body was a few feet long and its air-filled lungs persuaded anatomists it must be a reptile.
ARE WE THE ONLY SPECIES TO HAVE BEEN THROUGH A STONE AGE?
The Stone Age might conjure up images of early humans, sitting around a campfire or hunting prehistoric beasts, but evidence shows that we're not the only species that has learned how to work with stone tools. Wild chimpanzees (Pan troglodytes) use stone tools to crack open nuts.
Should we scrap daylight saving time?
Most of us look forward to the extra hour we get in bed every October, but researchers argue that changing the clocks twice a year harms our health

SCIENTISTS ARE USING ELECTRONIC TAGS AND SATELLITES TO TRACK WILD ANIMALS AND CREATE A DATA NETWORK THAT COULD HELP US ADDRESS THE BIODIVERSITY CRISIS
MUSIC FOR A DISTRACTED GENERATION
The number of things competing for our attention is often overwhelming. Can dreamy soundscapes created with neuroscience help our bewildered brains to concentrate?
