Outbreaks of pimples, blackheads and cysts are a cause of enormous anxiety and embarrassment among teens and young adults. If you’re part of the 20% of Australians who have experienced severe acne, you’ve probably tried a raft of treatments and preventive measures. But does giving up chocolate help? It’s unclear where or how this myth arose, but researchers tested the link three times from 1965 to 1971, suggesting it must have been a commonly held belief at least 40 years ago. All three studies came up with the answer: chocolate doesn’t exacerbate acne.
In the first comprehensive experiments with a mercury thermometer in 1851, Carl Wunderlich demonstrated in studies of more than 25,000 individuals that the normal body temperature was around 37°C. He also noted that “grown up women may be a trifle warmer than men of an equal age”. Subsequent studies have suggested that if this difference exists at all, it’s imperceptibly small. However, there are a few situations, such as pregnancy and hormonal contraception use, where women’s core temperature are more clearly a little higher than men’s.
Hair removal is a modern obsession. Despite the economic downturn, the beauty industry is booming, and it seems that a big part of looking good is getting rid of unwanted hair. Men as well as women are increasingly forking out big dollars for “permanent” hair removal treatments, preferring to shun the traditional character-building cold steel of a safety razor. Maybe it’s the risk of cuts, but undoubtedly part of the attraction of longer-term hair-removal treatments is the conventional wisdom that shaved hair grows back faster and thicker than it was before.
"There are 6 billion cell phones worldwide but what do we really know about the effects of this revolutionary technology?" asks the makers of a new documentary film, Disconnect, which looks at the potential health risks of cell phones. The filmmakers released a short YouTube video about a woman who was diagnosed with breast cancer after years of carrying her cell phone in her bra strap. It's anecdotal, to be sure, but potentially worrying. Watch the video after the jump.
