From vitamin C and echinacea to warm clothes and antibacterial soap, there’s no shortage of ideas about how to prevent and manage colds and flu. Unfortunately, many of these are not based on solid scientific evidence. In fact, medical researchers are only starting to unravel the range of factors that affect our susceptibility to getting an infection. Now we have discovered that our body clock plays an important role – making us more prone to get infected at certain times of the day.

You've got data pouring in from your connected fitness tracker, your smartphone, your smartwatch, the smart scales in your bathroom and the dieting app you use to log your meals — so how do you get all of this information in one place? It isn't easy, but here are a few pointers to help.


I know they say you can deep fry anything, but it's not an expression I took literally. Then I find out you can deep fry booze and well, there's little room for milder interpretations. Collingwood's Bendigo Hotel appears willing to stick all sorts of spirits into the deep fryer, with its latest concoction involving tequila.


The scale is fickle: We lose weight when we pee or when we do a sweaty workout. We gain weight when we eat or drink or put on a sweater. But how much does that kind of fluctuation really impact the numbers we see? I weighed myself 15 times in one day to find out.


Dear Lovehacker, I recently spent the night with someone and now I'm getting strong attempted-relationship vibes from them. To be honest, these vibes were kind of there before too. I will definitely see them at work-related events in the future and I'm not sure how to avoid this situation. Help? Thanks, Tyler.


Homo sapiens is a very moody species. Even though sadness and bad moods have always been part of the human experience, we now live in an age that ignores or devalues these feelings. More's the pity. Here's why bad moods are good for you.


Do your relationships always end in heartbreak? You're not alone. Around 35 per cent of Australian marriages end in divorce - and that's just couples who manage to tie the knot. When you factor in dating couples and de facto relationships, the percentage of breakups is much, much higher.

The good news is that scientists have been studying what makes couples happy using actual science. This infographic from Happify breaks down their chief findings, from optimum positive/negative interaction ratios to the importance of communication.


Female ejaculation – commonly known as "squirting" – has been a subject of interest right back to ancient times. Back then, however, it wasn’t a puzzle or taboo. The philosopher Aristotle, who was kicking around Ancient Greece more than 300 years BC, matter-of-factly observed that when women ejaculate, they produce far more liquid than men. And the Kama Sutra, the Hindu sexual text written around 200-400 AD, called the product of squirting ‘female semen’. It’s clear that for some of our ancient sisters ejaculation at orgasm was a normal part of sex.

As with so many aspects of women’s sexuality, however, over the last two millennia female ejaculation became a taboo subject. Then in the mid 20th century its existence was even denied by early sexual researchers and was written off as just incontinence (charming!).
