Cyclones linked to surge in cardiovascular disease, study finds
Photo: 123rf Researchers have found that cardiovascular hospitalisations rise after tropical cyclones. Researchers at Monash University in Melbourne and Otago University assessed hospital data from Canada, New Zealand, South Korea, Taiwan, Thailand and Vietnam from 2000-19, as well as recorded data from 124 cyclones. They found hospitalisations for cardiovascular disease (CVD) tend to rise, with this rate peaking at 2 months after the event, and the increase lingered up to 6 months after a tropical cyclone. The team also looked at variables, including sex, age, socioeconomic status and geographic location. Results showed a statistically significant and prolonged association between cyclones and CVD hospitalisation for people of all sexes aged 20-59. The team also evaluated six different types of CVD based on hospital diagnostic codes - heart failure, ischemic heart disease, hypertensive heart disease, heart rhythm disturbances, peripheral vascular diseases and stroke. Ischemic heart diseases and stroke were the two most common subsets of cyclone-associated CVD, and the latter was especially common in males of all ages. Areas with higher levels of socioeconomic deprivation had higher rates of cyclone-associated CVD hospitalisations, but the opposite was the case in areas with stronger socioeconomic advantages. "The study demonstrates that, as well as directly causing immediate deaths and injuries, extreme climate events can have important indirect health impacts over following months," said Professor Simon Hales, an epidemiologist at the University of Otago and one of the study's authors. "These delayed, indirect health impacts are due to infrastructure damage and disruption to livelihoods in the aftermath of major storms. "It is important to understand these health effects and mechanisms in more detail in order to design adaptive responses, as well as to motivate climate mitigation measures. "Cyclones, storms and heavy rainfall events are projected to become more frequent, unless stronger efforts are made to reduce emissions of greenhouse gases," he said. Associate Professor George Laking - executive board member of OraTaiao, the New Zealand Climate and Health Council - said similar work was done after Cyclone Gabrielle for populations in Tai Rāwhiti and Hawke's Bay. "We weren't able to detect that signal in our own project. I think that is explained by the smaller populations we studied. "In this report, there is a higher level of uncertainty in the New Zealand country-specific data. I think this represents our overall smaller population. "Interestingly, the strongest signal in New Zealand was for the north of the South Island, not so strong for the East Coast North Island regions we studied." Laking said he had waited for this study, showing the adverse interaction of cyclones and cardiovascular health. "Under climate change, we have to expect an increased incidence and severity of adverse weather events. That is a consequence of the greater amount of energy and water in the atmosphere. "These incredibly destructive events are adverse for human health in all sorts of ways." Laking said climate change had been identified as the No.1 risk to human health this century.

Can you control your dreams?
Ancient societies considered dreams to be either supernatural communication or a means of divine intervention. But in modern times, our minds and dreams have become the research topic for neuroscientists Dr. Benjamin Baird, a research professor of cognitive neuroscience at The University of Texas, is one of them. His studies include how we can control our dreams and how lucid dreaming can affect us when we're awake.

Does cheese give you weird dreams? Research say it does
Photo: News 2 Me - Dreams It is a question that may have grated on you for sometime, does too much cheese give you weird dreams? According to new research, yes it does, but not just any dreams, more often nightmares. An online survey of more than 1000 students at Canada's MacEwan University found a strong association between bad dreams and lactose intolerance, potentially because gas or stomach pain during the night affects people's dreams. Students were asked about about sleep patterns and any perceived association between different kinds of dreams and foods. About a third of respondents reported regular nightmares. Roughly 25 percent thought particular foods could make their sleep worse. Women were more likely to remember their dreams and to report poor sleep and nightmares and they were twice as likely as men to report a food intolerance or allergy. Researcher and Director at Montreal's Dream & Nightmare Lab at the Center for Advanced Research in Sleep Medicine Dr Tore Nielsen told Checkpoint they found three key findings that all pointed to food being associated with bad dreams. "The first one was that people who had lactose intolerance were reporting more nightmares, and the severity of their symptoms was associated with the severity of the nightmares. So a linear relationship there." Nielsen said that food allergies were generally also associated with nightmares in the same way. The third finding showed that an unhealthy diet could also be a trigger for a restless nights sleep. "An unhealthy diet in general was associated with bad dreams and nightmares," Nielsen said. "By unhealthy I mean, eating very close to bedtime... but also not depending upon your internal signals or when you're hungry, and when you're full." While it was not a firm finding, Nielsen said it was very likely that the severity of lactose intolerance would have an impact on the severity of the dreams. "Many people don't know their status when it comes to lactose intolerance. I mean, it's a kind of spectrum, right? There's a there's very severe cases of lactose intolerance and then very, you know mild cases... the problem is that people will dose themselves with dairy according to their symptoms, you know, and doctors in fact tell people don't just quit entirely if you only have a mild case. "People don't always judge this accurately or adhere to a strict enough diet. So, they do end up getting these symptoms when they're sleeping and they do end up affecting their dreams." The research is yet to reach the point of discovering whether specific cheese's cause certain types of dreams, but Neilsen said it has been attempted before. "The British Cheese Board, they published a study many years ago, and of course they gave people different kinds of cheese... and they claimed that they saw different patterns in the dream content depending on the type of cheese that they'd eaten." "I forget which one, maybe the cheddar, but it triggered dreams about celebrities." However, Neilsen said he highly doubts the accuracy of those findings. "There's a conflict of interest in that it was the Cheese Board itself that ran the study, and it was never published in any kind of scientific journal. So, I think that was a little bit of disinformation that got out there on the internet." For those who struggle to recall their dreams, cheese induced or not, Neilsen said there are a few ways to spark your memory. "Have some a pad of paper or like something that you can record your dream on... it helps to have that by your bed so that if you wake up in the middle of the night, and you have a dream that you can quickly jot down some notes." "It helps if you don't move when you wake up, because movement for some reason seems to really dissipate your memory of the dream." Other ways to make your dreams stick included waking up slightly earlier than usual, people who forget their dreams often wake up in the wrong sleep stage. Neilsen said it's better to wake up from REM sleep because that's where most of the vivid dreaming occurs.
