But does this mean that cold weather causes colds? Well no, viruses cause the common cold.
But, as Norman and Tegan explain, winter does set the stage for those viruses to have more moments in the spotlight.

Eastern Australia faces another round of rain and snow as La Niña watch declared
Any hope of a premature end to winter is fading fast. In fact, this weekend will bring some of the coldest weather of the season, as a two-pronged pulse of polar air sweeps well north. After wintry precipitation this weekend across south-east states, including small hail and snow, further heavy rain will then develop along the New South Wales coast from Monday where this August is quickly becoming one of the wettest on record. The prospects of cool and wet weather lingering into spring is also rising for central and eastern Australia — just weeks after a negative Indian Ocean Dipole (IOD) formed, the National Oceanic and Atmospheric Administration (NOAA) has now declared a La Niña watch for the coming months. Twelve months ago, Australia's capitals were baking in unseasonable summer-like temperatures, including monthly highs of 33 degrees Celsius in Brisbane and 30C in Sydney, and 25C in Adelaide. Since 1910, August 2024 was nationally the warmest on record, following the third warmest in 2023. However, there will be no repeat of late winter warmth this year. A cold front swept onto the southern coastline on Friday, introducing polar air from the Southern Ocean, and with a second front trailing on Sunday, south-east states can expect an extended spell of temperatures as much as five below average. For today, isolated to scattered showers will impact southern South Australia, much of Victoria, and parts of NSW and Tasmania. The presence of a sub-Antarctic air mass will also lead to pockets of small hail and snow to low levels, although a lack of moisture will limit falls in non-alpine regions to just a centimetre or two. Saturday's lowest snow levels： So where could snowfalls arrive today? Dozens of non-alpine towns along the ranges may see a dusting, including on the higher hills around Trentham and Mount Macedon in Victoria, along with Bombala, Nimmitabel, Cooma, Jindabyne and Adaminaby in southern NSW. A few flakes are also possible this afternoon and tonight on the higher NSW Central Ranges and the Barrington Tops. The second pulse of polar air on Sunday will take a more western path over SA and western Victoria, and bring another round of showers and small hail. The trajectory of the coldest air over SA could lead to a rare light snowfall in the state, most likely on the higher Mount Lofty Ranges and southern Flinders Ranges. For Adelaide, Sunday is likely to be the coldest August day in five years with a maximum struggling to only 13C. Snow could then redevelop along the NSW ranges from Monday as the polar air tracks east, possibly including another snowfall on the Northern Tablelands, and the first settling snow of the year around the Blue Mountains. While the east coast will be spared a third consecutive weekend washout, as the polar air tracks east it will combine with moist onshore winds off the Tasman Sea to generate another week of rain. Model guidance on the amount of rain and location of the heaviest falls is currently variable, however the general consensus is between about 50 and 100 millimetres from about Brisbane to the Illawarra, although for now, heavy rain extending north of the NSW border is somewhat uncertain. For Sydney, where this August has already been the wettest in 27 years, another 100mm would make it the fourth wettest August since records began in 1859. The notable increase in recent rain across parts of Australia is partly the result of a wet phase of the Indian Ocean forming this winter, called a negative IOD. Once formed an IOD event normally lasts until December, but spring rain from this year's episode could be enhanced by the formation of a corresponding La Niña in the Pacific Ocean. The Bureau Of Meteorology no longer issues watches or alerts for climate drivers, however a watch was declared by NOAA this week after surveying a range of modelling through the coming months. "Based on this guidance and recent changes in the tropical Pacific, the forecast team narrowly favours La Niña thresholds being reached in three overlapping, three-month seasons," it stated in their monthly diagnostic report. However, even if La Niña thresholds are met this year, the event is looking short and weak, meaning in isolation the episode is unlikely to cause widespread flooding across Australia. But while La Niña's influence might remain minor, when combined with the wet signal from the Indian Ocean along with warm local waters surrounding Australia, the scales are still strongly tipped to indicate frequent rain this spring.

Ultraprocessed or not? It matters when following dietary guidelines
A diet full of ultraprocessed foods (UPFs) has generally been thought to be bad for your health – and a trigger for disease. But for the first time a study has looked at the health effects of UPFs within the context of national dietary guidelines. And while a minimally processed diet is still better for you overall, it's not all bad news if you're sticking close to those directions.

Bodybuilding champion dead at 37 in ‘unexpected' tragedy
Bodybuilding champion Hayley McNeff died on the weekend, with the news confirmed on Wednesday (Thursday AEST). She was 37, as the New York Post reports. According to an obituary published on the death of the young American was 'unexpected but peaceful.' Itauma vs Whyte & Goodman vs Ball | Sunday 17 August 3am AEST | Order this PPV event now with Main Event on Kayo Sports. 'Hayley was like a beam of light in this world. She had boundless energy and was very determined to achieve whatever she set out to do,' Hayley's dad, Dave, told People in a statement. 'She set her sights on bodybuilding and fitness and achieved the highest success that sector offered. She loved us and we love Hayley very much, we miss her madly.' McNeff's family is set to hold a service on Sunday and has asked for attendees to make a donation to the National Alliance on Mental Illness in McNeff's honour. Per the obituary, McNeff graduated from Concord-Carlisle High School and University of Massachusetts Amherst, and was an accomplished bodybuilder in the 2000s with state titles in Maryland and Delaware. She was also part of the 2005 documentary 'Raising the Bar', which highlights the world of the sport. 'The quest for getting huge will never end,' McNeff said about her career in the documentary. 'There's no limit. I hope there's a day that I'll be able to look in the mirror 100 per cent of the time and be like 'yeah man, I'm huge'.' After retirement from the sport, McNeff decided to pursue a graduate degree in psychology. 'She had a gift for making those around her laugh and feel welcomed,' the obituary reads. 'Her energy and determination was a constant in her life and she always accomplished what she set out to achieve. 'She treasured her friendships and nurtured strong, lasting relationships with those who knew her best. Hayley will be deeply missed by her parents, siblings, extended family and friends.' Upon hearing the news of McNeff's death, bodybuilding coach Dave Palumbo posted a tribute message on Instagram. 'I'm sad to hear of the passing of former woman bodybuilder @hayleysmash (HAYLEY MCNEFF) … she left us way too soon,' he wrote. 'She was a good soul, super intelligent and had tremendous potential as a bodybuilder. She appeared in @dave_pulcinella RAISING THE BAR videos back in the day and I was proud to be able to call her a friend. 'Prayers to her family and friends. R.I.P.' McNeff is one of many bodybuilders who have recently passed away. Zunila Hoyos Mendez died at 43 in June after she was killed in a hammer attack. A month prior, Gui Bull died at 30.
