A team of sleep scientists from Uppsala University now demonstrates that <strong>acute sleep loss impacts working memory differently in women and men<\/strong>.<\/p>\n<div id=\"text\">\n<p>In the current study from the Department of Neuroscience at Uppsala University, 24 young adults performed a working memory task in the morning following either a full night of sleep or a night of wakefulness. Half of the participants were females, and half were males. The set-up of the working memory task was to learn and remember 8-digit sequences. Contrary to expectations, <strong>males&#8217; working memory performance remained unaffected by sleep loss<\/strong>. In contrast, <strong>females remembered fewer digits after sleep loss than after a night of sleep<\/strong>. Importantly, even though their performance was reduced, females were unaware of the drop in working performance when sleep-deprived. A lack of awareness of impaired mental performance could increase the risk of accidents and mistakes, which can be dangerous in many private and occupational situations, both for the sleep-deprived person as well as for others.<\/p>\n<p>&#8220;Our study suggests that particular attention should be paid to young women facing challenges in which they have to cope with both a high working memory load and a lack of sleep. However, it must be kept in mind that we have not tested whether the observed sex-dependent effects of sleep loss on working memory during morning hours would also occur at other time points of the day. In addition, while our data suggest that <strong>sleep loss impairs working memory in a sex-dependent manner<\/strong>, this does not mean that the sex-differences we observed can be generalised to other mental or physical measures of how we are affected by sleep loss,&#8221; says Frida R\u00e5ngtell, PhD student at the Department of Neuroscience and lead author of the study.<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Uppsala University press release: Over the last few decades, a wealth of evidence has accumulated to suggest that a lack of sleep is bad for mind and body&#8230;. <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2018\/02\/study-examines-impact-of-acute-sleep-loss-on-working-memory\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[4,43],"tags":[18,443,362],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/25811"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=25811"}],"version-history":[{"count":3,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/25811\/revisions"}],"predecessor-version":[{"id":25845,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/25811\/revisions\/25845"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=25811"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=25811"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=25811"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
