Summer sports and the heightened risk of skin cancer
3 February 2025
As someone with an extremely fair complexion, any amount of exposure to the sun can be risky, even over the winter months, when ultraviolet (UV) levels are generally lower. Trying though to explain this anyone who does not also have fair skin, is almost an uphill battle.
In fact, I’m alarmed at just how blasé some people are to the dangers of sun exposure, especially prolonged exposure. The sad reality is, that everyone, regardless of skin type, is at risk. Despite this, being out in the sun is an innate part of the Australian psyche. It’s no surprise then that rates of skin cancer in Australia are among the highest in the world.
But the message seems to getting through, albeit at a glacial pace. The Australian Institute of Sport has twigged onto the danger of sports events taking place in the blazing summer sun, and in 2023 said sporting organisations had a duty of care to provide safe environments for participants and spectators. It’s a start, but many sporting groups have been slow to take action.
But there are a number of options for creating sun safe sporting environments. These include providing adequate shade, and scheduling events at times of the day when UV levels are lower, and considering day/night fixtures where possible.

For the best health outcomes, drink coffee only in the morning
28 January 2025
Research recently published in the European Heart Journal seems to make sense:
Drinking coffee in the morning may be more strongly associated with a lower risk of mortality than drinking coffee later in the day.
A shot or two of caffeine earlier in the day must be better than consuming coffee through out. No one needs to be dealing with the prospect of caffeine shakes come evening time.

Apple Cider Vinegar, the ‘true-ish’ story of wellness guru Belle Gibson
22 January 2025
Belle Gibson is a former Australian wellness influencer who claimed to have cured herself of several cancers by way of a diet, exercise, and alternative medicine regimen. Her story brought hope to others stricken with similar diseases. But it seemed too good to be true, and it was. Investigations later revealed Gibson had been healthy, and disease free, the entire time.
In addition, Gibson claimed to be making donations to a number of charities, through money she had raised, but these organisations saw little, if any, of these funds. Her story is the subject of a “true-ish” Netflix produced TV mini-series, Apple Cider Vinegar, trailer, which premieres on Thursday 6 February 2025.
I’m not quite sure about the “true-ish” tagline of the series. I take this to mean some of the story is factual, while some is fiction. Netflix say they did not speak to Gibson during production of the show, but worked “carefully” to fend off the possibility of legal action being taken against them.

Time to replace the BMI as a measure, or otherwise, of obesity
20 January 2025
The Body Mass Index (BMI), may, at last, be about to be shown the door. Health care experts from across the world have been calling for a new means of defining obesity, according to research published by The Lancet:
We recommend that BMI should be used only as a surrogate measure of health risk at a population level, for epidemiological studies, or for screening purposes, rather than as an individual measure of health. Excess adiposity should be confirmed by either direct measurement of body fat, where available, or at least one anthropometric criterion (eg, waist circumference, waist-to-hip ratio, or waist-to-height ratio) in addition to BMI, using validated methods and cutoff points appropriate to age, gender, and ethnicity.
It’s always struck me as an odd way to determine whether a person is of a healthy, or otherwise, weight, simply by dividing their height by their weight.
My BMI has always been in the OK zone, but I often wondered how it could useful for people who are, say, professional athletes, or front-rowers of the Wallabies. Surely their height to weight ratios would send the BMI into meltdown. I queried a past GP about this, who told me the BMI was but one tool available to medical professionals, but did not elaborate further.
I made me immediately think if there are other such measures, why aren’t they used more widely.

Mysterious, deadly, flu-like disease outbreak in Congo
10 December 2024
The details are pretty scant at the moment. So far the flu-like disease killed close to one-hundred-and-fifty people in the south west of the Democratic Republic of the Congo, in November.
Infected people had flu-like symptoms including high fever and severe headaches, Remy Saki, the deputy governor of Kwango province, and Apollinaire Yumba, the provincial minister of health, said on Monday.
Whether the illness is contained and dealt with, or spreads further, remains to be seen. It sounds nasty though, whatever it is.

The science of standing desks does not quite stack up
13 November 2024
Pretty popular are sit/stand desks at the moment. I’ve helped a few people assemble them, when they’ve bought one for their home office. Good for your health, sit/stand desks, or so we’re told.
Mainly because you’re not sitting all day while working. Some recent research however, suggests the health benefits of sit/stand desks could be overstated. Sitting for extended periods may not be ideal, but too much time spent standing can also cause problems:
“More time spent sitting didn’t necessarily lower a person’s risk of cardiovascular disease, nor did it increase the risk,” Ahmadi says. “It was a null finding. But what it did do was actually increase their risk of circulatory diseases.” Standing for more than two hours a day increased that risk by 11 percent for every extra half hour, which is bad news for retail workers and the standing desk industry.

How to reduce bad screen time, while needing good screen time?
17 October 2024
Mary Grace Descourouez, writing for Stanford Lifestyle Medicine:
Additional studies found that adults who engage in excessive screen time or have a diagnosed smartphone addiction had lower gray matter volume. Gray matter is brain tissue essential for daily human functioning and is responsible for everything from movement to memory to emotions. Gray matter volume naturally decreases as we age, so along with reducing screen time, engaging in activities that maintain our gray matter volume and promote brain health, such as exercise and movement, restorative sleep, social engagement, and stress management, is crucial.
I think it’s a given that an excess of time spent gazing at computer and laptop screens is detrimental to our health and well-being. But these devices are deeply ingrained in our lives, so going cold-turkey, or switching to a dumbphone, AKA a featurephone, aren’t exactly realistic options. Even though some people have reported a marked difference in well-being, from doing so.
Nor are the simplistic calls made by some to go “back to the old ways”, because it worked for them, in their day. For my part, being able to do so much, from a device in my hand, sees me lead a life and work style that earlier generations of my family could not have possibly imagined. While I’m full well aware of the dangers of too much screen time, I’m not about to dumb-down anytime time soon.
We get around over-doing screen time by getting outside for two to three hours daily, weather permitting, in the early evenings. Naturally we carry our phones with us, in the event family or friends need to make contact. Moving at a brisk pace for several hours though is not much conducive to looking at a screen, so we score at least a few screen-free hours. Taking a solid break like this seems more sensible than trying to ration, or restrict, looking at screens, at other times.
At least, that’s our experience.

Playing Tetris may ease post-traumatic stress disorder symptoms
24 September 2024
Sara E. Teller, writing for Legal Reader:
The research, published in BMC Medicine, focuses on the use of video games, particularly the well-known Tetris game that has been around for decades, to help reduce intrusive memories, a core and sometimes debilitating symptom of the condition.
Invented in 1984 by Alexey Pajitnov, Tetris is a straightforward yet fun, video game. Anything that can help PTSD survivors, in any way, has to be a good thing.

Moderate drinking is not beneficial, in fact is it harmful
1 August 2024
Michael Le Page, writing for New Scientist:
Drinking even small amounts of alcohol reduces your life expectancy, rigorous studies show. Only those with serious flaws suggest that moderate drinking is beneficial. That’s the conclusion of a review of 107 studies looking at how drinking alcohol affects people’s risk of dying from any cause at a particular age.
I’ve hardly touched alcohol in ten years. I didn’t make a conscious decision to stop drinking as such, I woke up one morning and simply didn’t feel like having it anymore. End of story. But I’m not one-hundred teetotal. I have a swig now and then. New Year’s Eve was the last time, I think. But I know I’m fortunate, and that stopping, or giving up, is far from straightforward for some people.

Your fixed calorie budget stops weight loss through exercise
23 July 2024
This news, via Kurzgesagt, may not be what some people want to hear. Exercising is useful, necessary in fact, but not so much when it comes to trying to lose weight it seems.
Active people who work out regularly do burn more than inactive people. But only very little, often as low as 100 calories, the equivalent of a single apple. For some strange reason, the amount of calories you burn is pretty much unrelated to your lifestyle. Per kilo of body weight, your body has a fixed calorie budget it wants to burn per day.
