‘Have a serious think': Health Minister Mark Butler urges COVID boosters as new NB.1.8.1 variant surges
Health Minister Mark Butler has urged Australians to get their COVID booster jab after a surge in infections from the new subvariant NB.1.8.1.
The variant is behind surging infections in parts of Asia, with the World Health Organisation reporting it is spreading faster than other circulating strains.
Wastewater screening in WA has detected the new highly contagious variant of Omicron as the dominant variant in Perth.
Mr Butler said people aged over 75 should seek out a booster if it's been more than six months since their last, while those aged between 65 and 74 should get one if it has been more than a year.
'For everyone else, have a serious think,' he warned.
'I do encourage, particularly as we head into winter, for people to think about the last time they got the COVID vaccine.
'I've just got my booster over the last couple of weeks, and I think that puts me in a good position over winter, and other Australians should make sure that they equip themselves similarly.'
Monash University's head of epidemiological modelling James Trauer warned if people weren't up to date with their boosters and had previously suffered from the Omicron they could be more at risk.
'You're just more likely to get it. You're more susceptible if you've been infected with a variant that was around two or three years ago and if you've been vaccinated with a vaccine that's a couple of years old,' he said.
'That will provide you with less protection. So if you have had a bit of a gap since your last infection you could get a somewhat worse episode this time around.
'Omicron has continued to evolve and its throwing off offshoots. This one is just a step on from the last one.
'The virus gradually evolves so that some of its proteins are a little bit different so that it can avoid the antibodies that we've now got present at population level.'

Alarmist content in Australia's National Curriculum is causing an ‘epidemic of climate anxiety' among kids, report warns
Alarmist content in Australia's National Curriculum is causing an 'epidemic of climate anxiety' that is robbing kids of their childhood, a new report has warned. Kids in all of Australia's states and territories are taught content from the national curriculum from the beginning of primary school, but leading educational and developmental psychologist Clare Rowe argued it is causing 'real damage to the mental health of young Australians'. In a new report on climate anxiety in pre-adolescent children, Ms Rowe argues climate change content being taught to young kids is 'developmentally inappropriate', and should, at the very least, be postponed until secondary school. 'As a clinician, it is alarming to see so many children in my practice who are fearful and feel hopeless due to the climate education they receive at school,' Ms Rowe told In the report, published by the Institute of Public Affairs, Ms Rowe says educational and developmental psychologists like her were seeing more and more patients suffering from 'eco-anxiety' – persistent worry about the future of the planet, often linked to chronic stress, reduced psychological well-being and a sense of helplessness. 'In recent years, I have witnessed an alarming trend: more and more young children entering my clinic, gripped by fear that they will not live to see adulthood. They tell me with absolute certainty that the world is ending, that the government doesn't care and that the adults around them have failed,' she states. 'These are not isolated incidents. My colleagues and I have seen a marked rise in children experiencing anxiety linked to the way climate change is taught in schools.' According to a 2021 study with 10,000 participants across ten countries, 59 per of cent of people aged 16 to 25 were very or extremely worried about climate change. While there is less data about the level of eco-anxiety among primary school aged children, surveys have found that almost a third of Australians aged 10-13 are worried about the state of the environment. Since it was established, the National Curriculum has included 'sustainability' as one of its three cross-curriculum priorities. This means content about the environment and climate change is present in all subjects, ranging from science to English and even maths. The report explains that in order to fulfil their teaching requirements, many schools utilise third-party education resources, some of which are developed by activist groups. 'The framing of these materials often leans towards an urgent and alarmist narrative, often emphasising children's role in taking action against climate change,' the report states. The examples listed include a lesson aimed at nine-year-olds and developed by Scootle which teaches that climate change is 'threatening humankind and pushing people into poverty'. The report also points to a resource developed by ABC's 'Behind the News' program. Aimed at kids aged eight and above, the resource 'educates young children by showing them emotive video footage of raging bushfires, floods, cyclones and melting ice caps'. 'These images are displayed with a backdrop of dramatic music and an overlay of children's testimonies about how worried they are for their future,' the report states. According to Ms Rowe, it is 'developmentally inappropriate' to be teaching primary school-aged children about climate change, since it 'exposes young minds to allegedly existential threats that they cannot meaningfully understand or act upon'. 'Young children lack the cognitive capacity to process abstract, multifactorial problems such as global climate change. Without the necessary reasoning skills, they are prone to misinterpreting information in ways that fuel excessive fear, helplessness, and anxiety,' the report states. 'For example, a child who hears that climate change is a risk to coastal communities, health and food security may internalise these statements literally, believing that complete environmental collapse is imminent within their lifetime. 'This misinterpretation can lead to excessive fear, confusion and distress, rather than constructive engagement with environmental issues.' The developmental psychologist also argued the heightened state of stress this causes can rob kids of their childhood. 'When young brains are routinely pulled into a heightened state of stress, their ability to engage in age-appropriate developmental tasks such as play, exploration and social learning is significantly diminished,' the report states. Ms Rowe argues that in order to reduce the growing prevalence of eco-anxiety, climate change education should at the very least be delayed until secondary school. The leading psychologist is also calling for the National Curriculum to be rebalanced. 'We must also abolish the National Curriculum Cross-Curriculum Priority of Sustainability, which sounds nice, but is causing untold damage,' she told 'Our children should be focused on core competencies of literacy and numeracy in primary education. These are the foundational skills upon which all future learning depends.'

The drug free treatment for insomnia
A conservative estimate is that more than 40 per cent of Australians do not get a good night's sleep. But comparatively little is being done to raise awareness of or treat endemic sleep issues which experts warn are on the rise. This story is from reporter Ellen Coulter and producer Rahni Sadler.

Gen X is facing an unprecedented mental health conundrum – here's why
Don't miss out on the headlines from Lifestyle. Followed categories will be added to My News. While of course every generation is faced with different sources of stress and hardship, the report reveals Aussies classed as Generation X – born between 1965 and 1980 – are facing an unprecedented challenge. According to a new report conducted by Medibank and News Australia's The Growth Distillery, an overwhelming majority of Gen X Aussies are tasked with caring for both their aging parents and aging children. Despite experiencing considerably more financial security, home ownership and career establishment than younger generations, the increasing financial, emotional and physical pressure to act as caretakers for the generations preceding and succeeding them is negatively impacting the mental health of Gen X Aussies. Gen X: The Caretaker Generation Thanks to advancements in technology, research and healthcare innovation, as well as decades of healthy habits, people are now living well into their 80s and 90s, with some even hitting triple digits. But as more elderly Aussies reach a milestone age, we're presented with a unique set of challenges. With Australia's healthcare and aged care systems somewhat overwhelmed by the increasing number of elderly Australians, the onus to provide care and support often falls on members of Gen X. On the flipside, the rising cost of living and unwavering housing crisis are forcing many younger Australians to depend more heavily on their parents (again, Gen X) for financial support. As a result, a large proportion of Gen X Aussies have been forced to take on the role of caretaker for both their children and their parents, a sandwich of responsibility no other generation has yet to experience in the same way. Gen X find it particularly difficult to open up to their children about their mental health. Image: iStock Pressure to support those around them Despite bordering on the age of retirement, many Gen X Aussies are working later in life due to the sustained cost of living and dependency of other generations. As a result, Gen X reports their main source of stress is financial responsibilities such as mortgages and retirement planning. The State of Mind: Australia's Mental Health Conversation report also reveals that managing the health issues that come with aging, such as menopause, is another factor significantly impacting Gen X's mental health. With the responsibility of supporting their children and parents – financially, physically and emotionally – often falling solely on them, Gen X reports feeling a reluctance to burden others with their problems, especially when it comes to speaking about their mental health. There is a serious need for improved mental health literacy and communication across all relationships. Image: iStock Overcoming a reluctance to open up While a reluctance to burden others is a universal barrier, Gen X find it particularly difficult to open up to their children about their mental health and any struggles they may be experiencing, despite their children being adults themselves. According to the report, 28 per cent of parents of 16 to 30-year-olds reveal they've never had a conversation about their own mental health with their adult children. Hesitancy aside, the report reveals a strong desire among younger Australians to have more frequent and open discussions about mental health with their Gen X parents, but also that 8 in 10 Australians expect parents to initiate conversations with their children. According to the statistics, there is a serious need for improved mental health literacy and communication across all relationships, especially between those stemming from different generations. With Gen X feeling overly burdened by the financial and emotional needs of those around them, as well as a pressure to support and provide for them, it's imperative that we find methods of enhancing communication to strengthen family support systems across the board. According to the report, despite 4 in 10 Aussies finding it difficult to relate to the challenges and struggles of different generations, 70 per cent of people believe that hearing their parents share their personal struggles would make them more comfortable discussing their own.
