The UV Index was created last century largely for North American and European conditions, which rarely reach the ‘extreme’ range.
Alongside the day's high and low, weather reports generally contain a UV alert for a particular time. But what does it actually mean – and what should you do about it?
Trans fats increase the shelf life of bakery goods and fast foods.
When you buy commercially baked goods such as pies, pastries, cakes and biscuits, there's a good likelihood they'll contain one of the nastier types of fatty acids: trans fats.
Chewing your food for longer gives your brain more time to realise you’re full, meaning you’re less likely to overeat.
While 32 is an arbitrary number, chewing your food for longer could actually aid weight loss.
The yellow fever mosquito Aedes aegypti isn’t put off by this ‘mosquito repellent’ wrist band.
While slipping on a wrist band or sticking on a patch may be an attractive alternative, they’re unlikely to provide any substantial protection from biting mosquitoes.
Talk to your GP if you notice any moles or lesions that have grown, or changed shape or colour.
Australia has one of the highest rates of skin cancer in the world. Two-thirds of Australians will be diagnosed with skin cancer by the age 70.
A considerable proportion of childhood asthma is attributable to exposure to indoor dampness and mould.
Exposure to harmful agents inside the home can have profound effects on our health. After all, we spend an average of 16 hours a day at home – and even more when aged under seven and over 64.
Spiders such as this funnel-web (Hadronyche infensa) will only bite if threatened.
There are more than 45,000 species of spider, but only a handful are potentially dangerous to humans.
If you're one of the 15% of Australians who experience hay fever, it's likely you've spent weeks sneezing, itching and trying to control a runny nose and cloudy head. So, what can you do about it?
While nutrient supplementation can have a role in treating certain psychiatric disorders, all kinds of nutrients should, in the first instance, be consumed as part of a balanced wholefood diet.
A growing body of research points to the detrimental effect of unhealthy diets and the protective value of healthy diets – along with select nutritional supplements as required – for maintaining and promoting mental health.
Look for a warning on the box before you attempt to crush or chew tablets, or cut capsules open.
Some people are incapable of swallowing tablets because of physical or psychological reasons. What should they do when the doctor prescribes a drug that comes in tablet form?
We now have the technology to do track our sleep through the night, but that may be doing more harm than good.
Tracking sleep is now routine in monitoring overall well-being. But are the devices used to do this actually useful, or have we simply found a more sophisticated way to clock watch?
Here’s a clue: what you eat is just as important as the size of your meal.
We’ve all done it: enjoyed a delicious meal only to nod-off in a comfy chair for a while. A habit for some but unavoidable for others, what is it about food that can make us so sleepy?
Think of it as a useful signal from your body.
It's normal to experience muscle pain after exercising if it's been a while since you were active or performed a certain movement.
Even in a dreary office, by understanding how your brain works you can change how it feels to be there.
In many of the workplaces I visit as a neuroscientist, stressed workers behave much like addicted lab rats. But you don't have to quit the rat race to start feeling better at work.
Some people believe stretching reduces the risk of injury, reduces soreness experienced after exercise, or enhances sporting performance.
Many people stretch when they exercise or play sport. Others don’t stretch but feel they should. And some people don’t see any reason to stretch at all.
Around the world, tea is the most common drink after water.
Put the kettle on and relax with a cuppa; your brain, heart and waistline will thank you.
Chocolate milk is well supported by research as ticking all the boxes for an effective exercise recovery drink.
The decision to use protein supplements is based more on marketing claims than anything else. They offer few real performance benefits that an athlete’s normal diet isn’t already delivering.
The head louse is usually relatively harmless and more of a nuisance than a disease.
We humans think we sit on top of the food chain, but the pediculosis capitis mite – the head louse – sits above us, on the top of our heads.
Too much sitting may increase the risk of developing diseases including heart disease and type 2 diabetes, and it may even cause premature death.
More people are getting standing desks in response to our increasing knowledge about the harms of sedentary lifestyles. But can you transition to standing at work without causing yourself harm?
Tension-type headaches feel like a dull or heavy, non-pulsating band of pain, usually on both sides of the head.
Nearly every second person in the world had a headache at least once in the past year. But these can feel very different, depending on which of the nearly 200 types of headache you have.
