We often hear about the health risks of second-hand smoke, or passive smoking, but now a new study reveals that third-hand smoke can be dangerous too. Third-hand smoke is the term used to describe tobacco contaminants that stick to walls, carpet, bedding and other surfaces, leading to a room smelling like an ashtray. However, research by Yale University has revealed that third-hand smoke actually clings to a smoker’s body and clothes as well, allowing it to be released into environments where smoking has never occurred. While this might not sound like too big a deal, the worrying revelation from the study is that non-smokers in such environments can be impacted. In fact, the study says chemical exposure in a movie theatre could be the equivalent of being exposed to between one and 10 cigarettes of second-hand smoke by the end of the movie. Speaking about the findings of the research, Drew Gentner, study authord and an associate professor of chemical and environmental engineering at Yale University, said: “People are substantial carriers of third-hand smoke contaminants to other environments. So, the idea that someone is protected from the potential health effects of cigarette smoke because they're not directly exposed to second-hand smoke is not the case.”
A new study has revealed that many people in England are unsure about cancer risk factors and often incorrectly identify fake cancer causes. The survey of 1,330 people found that drinking from plastic bottles and using microwave ovens are two of the fake cancer causes people often cite. The good news is that 88% of people surveyed correctly identified smoking as a major cancer risk factor, while 80% picked passive smoking and 60% said sunburn were also causes of cancer - all of which have been proven. According to Cancer Research UK, smoking, overexposure to UV radiation and being overweight are the biggest preventable causes of cancer. In fact, the charity says that about four in 10 cases of cancer could be prevented with lifestyle changes and people need the right information to help them "separate the wheat from the chaff". Researchers from University College London and the University of Leeds conducted the survey and discovered that more than 40% of participants wrongly thought that stress and food additives caused cancer. Dr Samuel Smith from the University of Leeds said: "It's worrying to see so many people endorse risk factors for which there is no convincing evidence. "Compared to past research, it appears the number of people believing in unproven causes of cancer has increased since the start of the century, which could be a result of changes to how we access news and information through the internet and social media." Clare Hyde, from Cancer Research UK, said: "There is no guarantee against getting cancer - but by knowing the biggest risk factors we can stack the odds in our favour to help reduce our individual risk of the disease, rather than wasting time worrying about fake news."
It’s natural for grandparents to dote on their grandchildren and give them sweet treats whenever they see them. But new research suggests this and other influences could have a negative impact on their grandchildren’s health. For the research, the team from the University of Glasgow analysed 56 different studies which included data from 18 countries, including the UK, US, China and Japan. They focused on the influence of grandparents who were significant in their grandchildren’s lives, but who weren’t necessarily primary caregivers. Three areas of influence were considered: diet and weight, physical activity and smoking. When it came to their grandchildren’s diet and weight, grandparents were found to have an adverse impact, with many studies highlighting how they feed their grandchildren high-sugar or high-fat foods - often in the guise of a treat. The researchers also found that grandchildren were perceived to get too little exercise while under the supervision of their grandparents. However, this did depend on whether the grandparents were physically active themselves or not. Furthermore, smoking around grandchildren became an area of conflict between parents and grandparents, with the latter often smoking while their grandchildren were present, even though they had been asked not to. Talking about the findings of the study, lead researcher Dr Stephanie Chambers said: "While the results of this review are clear that behaviour such as exposure to smoking and regularly treating children increases cancer risks as children grow into adulthood, it is also clear from the evidence that these risks are unintentional. "Given that many parents now rely on grandparents for care, the mixed messages about health that children might be getting is perhaps an important discussion that needs to be had."
