WASHINGTON: People may actually solve a problem better if they 'sleep on it', according to a study which suggests that brain processing during sleep is helpful to daytime cognition. The study, published in the journal Psychological Science, sheds light on information processing during sleep, as well as incubation for problem solving -- why we sometimes solve a problem better after a break. "We know that people rehearse or 'consolidate' memories during sleep, strengthening and reorganising them, " said Kristin Sanders, first author of the study and a doctoral student at Northwestern University in the US. "It's also known that this natural process can be boosted by playing sounds associated with the information being rehearsed, " Sanders said. The researchers hypothesised that rehearsing unsolved problems during sleep would help people refine their memories of the problems, and improve their chance to solve them the next day. In the study, people attempted several puzzles in the evening while listening to specific sound cues.
THC is present in most of the fluid samples collected from the lungs of ill people, and most patients report a history of using THC-containing e-cigarette, or vaping, products. 'Popcorn lung' is the nickname for bronchiolitis obliterans, a condition which damages the smallest airways in the lungs and has been linked to people with vaping-related breathing problems. However, there's no good evidence that e-cigarettes could cause the lung condition, according to Cancer Research UK. The flavourings in electronic cigarettes may damage blood vessels in the same way as heart disease, according to research published in June 2018. The chemicals used to give the vapour flavours, such as cinnamon, strawberry and banana, can cause inflammation in cells in the arteries, veins and heart. They cause the body to react in a way that mimics the early signs of heart disease, heart attacks or strokes, the study by Boston University found. Other recent studies have also suggested smoking e-cigarettes could cause DNA mutations which lead to cancer, and enable pneumonia-causing bacteria to stick to the lungs easier.
This combination could increase a person's appetite, making caloric restriction more difficult to adhere to, and may make a person more likely to overeat. Consequently, increased food intake due to changes in appetite hormones may result in weight gain. This means that, in the long term, sleep deprivation may lead to weight gain due to these changes in appetite. So getting a good night's sleep should be prioritized. Along with changes in appetite hormones, reduced sleep has also been shown to impact on food selection and the way the brain perceives food. Researchers have found that the areas of the brain responsible for reward are more active in response to food after sleep loss (six nights of only four hours of sleep) when compared to people who had good sleep (six nights of nine hours of sleep). This could possibly explain why sleep-deprived people snack more often and tend to choose carbohydrate-rich foods and sweet-tasting snacks, compared to those who get enough sleep. Sleep deprivation may make you eat more unhealthy food during the day.
The number of vape users in Britain has dropped by 400, 000 in just one year, according to campaigners. The charity Action on Smoking and Health (ASH) blamed a misguided belief vaping is just as harmful as cigarettes for the fall. In March, YouGov polling showed there were 3. 2million e-cigarette users in Britain - down from 3. 6million the year before, reported The Times. It comes as an international evidence review showed e-cigarettes were 70 per cent more effective in helping smokers quit than nicotine replacement treatments. Deborah Arnott, ASH's chief executive, said: 'About a third of smokers have never even tried an e-cigarette and less than 20 per cent are currently using one. The charity Action on Smoking and Health (ASH) blamed a misguided belief vaping is just as harmful as cigarettes for the drop (file image) 'If many more smokers could be encouraged to give e-cigarettes a go, the latest evidence indicates that many more might successfully quit. ' This year 17. 4 per cent of smokers used an e-cigarette while 17.
Suvorov will look for associations between PBDE levels in maternal blood and the activity of a protein known as mTOR in the baby's placenta. mTOR is thought to mediate the changes in liver metabolism caused by PBDE exposure. Researchers also will evaluate the effects of PBDE exposure on childhood lipid levels by examining the lipid profiles and markers of liver injury in the children at age 8-9. "We hypothesize that high PBDE levels are associated with higher triglycerides in childhood, " Suvorov says. "And the diseases come later. What will happen to them at age 50? That is my major research question.

The scientists say this exponentially increases the likelihood of disease. Debate over how harmful vaping is leads to confusion E-cigarettes have the potential to benefit some people, by helping them quit smoking. But scientists still have a lot to learn about whether e-cigarettes are truly effective for quitting smoking and what the long-term risks are. Nicotine is already known to be highly addictive and harm adolescent brain development, which continues into the early to mid-20s. E-cigarettes produce an aerosol by heating a liquid that usually contains nicotine. Aerosol is inhaled into the lungs and can contain potentially harmful substances, including heavy metals like lead, volatile organic compounds, and cancer-causing agents. US health officials, the Centers for Disease Control and Prevention (CDC), are investigating an outbreak of e-cigarette or vaping, product use associated lung injury (EVALI). The mystery illness has swept across the states. Officials have identified Vitamin E acetate as a chemical of concern.
Vaping is just as bad as smoking cigarettes for increasing the risk of heart disease Vaping causes significant damage to blood vessels in the same way as smoking traditional cigarettes, a study has found. Blood vessels become stiffer and less effective in vapers and people who both vape and smoke, compared to non-smokers. People who only inhale from cigarettes and do not vape also have the same issue of stiffening blood vessels. Nicotine — the addictive substance in vapes and cigarettes — constricts blood vessels and over time this leads to a loss of elasticity. Rigid arteries and blood vessels are known to increase a person's risk of developing heart disease. Researchers studied more than 400 men and women aged between 21 and 45 made up of non-smokers, cigarette smokers, e-cigarette users and people who both smoked and vaped. All e-cigarette users were former cigarette smokers. The study, published in the Journal of the American Heart Association on Wednesday, found that former smokers who switched to e-cigarettes and dual users had arteries that were just as stiff as those in traditional smokers.
Studies have shown that perinatal exposure of rats and mice to common flame retardants found in household items permanently reprograms liver metabolism, often leading later in life to insulin resistance and non-alcoholic fatty liver disease. Now, research led by University of Massachusetts Amherst environmental toxicologist Alexander Suvorov, with co-authors in Moscow, Russia, has identified the likely mechanism responsible for the pollutant's effect: an altered liver epigenome. The epigenome refers to heritable changes in gene expression without changes in the DNA sequence. "Changes in the liver epigenome can explain those functional changes in the liver, " Suvorov explains. "We looked at two different epigenetic mechanisms and there were changes in both. " Published Dec. 13 in the medical journal Epigenomics, the study showed that environmentally relevant exposure to polybrominated diphenyl ether (PBDE) through the umbilical cord and breast milk permanently changed liver metabolism in rats.
When it comes to weight loss, diet and exercise are usually thought of as the two key factors that will achieve results. However, sleep is an often-neglected lifestyle factor that also plays an important role. The recommended sleep duration for adults is 7 to 9 hours a night, but many people often sleep less than that. Research has shown that sleeping less than the recommended amount is linked to having greater body fat, increased risk of obesity, and can also influence how easily you lose weight on a calorie-controlled diet. Typically, the goal for weight loss is usually to decrease body fat while retaining as much muscle mass as possible. Not obtaining the correct amount of sleep can determine how much fat is lost, as well as how much muscle mass you retain while on a calorie-restricted diet. One study found that sleeping 5. 5 hours each night over a two-week period while on a calorie-restricted diet resulted in less fat loss when compared to sleeping 8. 5 hours each night. But it also resulted in a greater loss of fat-free mass (including muscle).
However, physical activity may show promise as a countermeasure against the detrimental impact of poor sleep. Exercise has a positive impact on appetite, by reducing ghrelin levels and increasing levels of peptide YY, a hormone that is released from the gut, and is associated with the feeling of being satisfied and full. After exercise, people tend to eat less, particularly when the energy expended by exercise is taken into account. However, it's unknown if this still remains in the context of sleep restriction. Research has also shown that exercise training may protect against the metabolic impairments that result from a lack of sleep, by improving the body's response to insulin, leading to improved glucose control. We have also shown the potential benefits of just a single session of exercise on glucose metabolism after sleep restriction. While this shows promise, studies are yet to determine the role of long-term physical activity in people with poor sleep. It's clear that sleep is important for losing weight.
