Regular daytime naps could be good for brain health, new research suggests. Daytime napping could slow the rate at which brains shrink as we age, the study led by researchers at UCL and the University of the Republic in Uruguay found. The researchers hope their findings into the health benefits of sleeping during the day will reduce any stigma that still exists around daytime napping. The study suggests the average difference in brain volume between people programmed to be habitual nappers and those who were not was equivalent to 2.6 to 6.5 years of ageing. Our findings suggest that, for some people, short daytime naps may be a part of the puzzle that could help preserve the health of the brain as we get older Dr Victoria Garfield, UCL Senior author Dr Victoria Garfield, MRC Unit for Lifelong Health & Ageing at UCL, said: “Our findings suggest that, for some people, short daytime naps may be a part of the puzzle that could help preserve the health of the brain as we get older.” The study, published in the journal Sleep Health, analysed data from people aged 40 to 69. Past research has suggested people who have had a short nap perform better in cognitive tests in the hours afterwards than those who did not nap. The new study looked at whether there was a causal relationship between daytime napping and brain health. Researchers looked at 97 snippets of DNA thought to determine people’s likelihood of habitual napping. They compared measures of brain health and cognition of people who are more genetically programmed to nap with people who did not have these changes in DNA, using data from 378,932 people from the UK Biobank study. They found that, overall, people predetermined to nap had a larger total brain volume. The genetic variants – DNA changes – influencing the likelihood of someone to nap were identified in an earlier study looking at data from 452,633 UK Biobank participants. But the researchers did not find a difference in how well those programmed to be habitual nappers performed on three other measures of brain health and cognitive function. Lead author and PhD candidate Valentina Paz, University of the Republic (Uruguay) and MRC Unit for Lifelong Health & Ageing at UCL, said: “This is the first study to attempt to untangle the causal relationship between habitual daytime napping and cognitive and structural brain outcomes. “By looking at genes set at birth, Mendelian randomisation avoids confounding factors occurring throughout life that may influence associations between napping and health outcomes. “Our study points to a causal link between habitual napping and larger total brain volume.” Garfield added: “I hope studies such as this one showing the health benefits of short naps can help to reduce any stigma that still exists around daytime napping.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Dramatic rise in the number of women freezing their eggs 9 glorious gardens to visit this summer How to keep flying insects out of your home

When it comes to approaching someone you like at a bar, it may be more a case of alcohol giving you liquid courage than “beer goggles”, researchers say. A new study suggests drinking alcohol makes people more likely to approach someone they already find attractive, but does not make others appear more attractive. Some people argue that intoxication makes others seem better-looking – but according to the researchers, this has not been systematically studied. Past research typically had people simply rate others’ attractiveness while sober and while intoxicated based on photos. But the new study added the possibility of meeting the people being rated. The study, led by Molly Bowdring of the Stanford Prevention Research Centre, Stanford University, in the USA (affiliated with University of Pittsburgh at the time of this study), and her dissertation adviser, Michael Sayette, involved 18 pairs of male friends in their twenties. The men were brought to the laboratory to rate the attractiveness of people they saw in photos and videos. They were also told that they may be given the chance to interact with one of those people in a future experiment. After the ratings were given, the men were asked to pick those who they would most like to interact with. Pairs of men visited the lab on two occasions – on one occasion they both received alcohol to drink – up to about a blood alcohol concentration of .08 per cent, the legal limit for driving in England, Wales and Northern Ireland, and the United States, and on the other occasion, they both received a non-alcoholic drink. Friend pairs entered the lab together in order to mimic social interactions that would typically take place in a real drinking situation. The researchers say they did not find evidence of beer goggles – whether or not the men were intoxicated had no effect on how good-looking they found others. Professor Sayette, from the University of Pittsburgh, said: “The well-known beer goggles effect of alcohol does sometimes appear in the literature, but not as consistently as one might expect.” However, according to the findings, drinking alcohol may affect how people react to those they find attractive in a different way. The researchers found it impacted how likely the men were to want to interact with people they found attractive. When drinking, they were 1.71 times more likely to select one of their top-four attractive candidates to potentially meet in a future study compared with when they were sober. The researchers suggest alcohol may not be altering perception but rather enhancing confidence in interactions, giving the men liquid courage to want to meet those they found the most attractive. According to the researchers, the findings could have implications for therapists and patients. Prof Bowdring said: “People who drink alcohol may benefit by recognising that valued social motivations and intentions change when drinking in ways that may be appealing in the short term, but possibly harmful in the long term.” The findings are published in the Journal of Studies on Alcohol and Drugs.
