on weekdays and weekends may be more likely to experience anxiety, according to a new study.<br \/>\n    <\/h2>\n<div class=\"c-article-content c-article-content--health js-article-content\">\n<p>As school starts and routines return to &#8220;normal,&#8221; many adolescents will struggle with early mornings after a summer of sleeping in and irregular holiday schedules. Throughout the school year, pupils count down to the weekend, hoping to recover the hours of sleep lost during the week \u2014 a pattern researchers call &#8216;social jet lag&#8217;. <\/p>\n<div>\n<div class=\"c-ad u-show-for-mobile-only\">\n<div class=\"c-ad__placeholder\"><img decoding=\"async\" class=\"c-ad__placeholder__logo\" src=\"https:\/\/static.euronews.com\/website\/images\/logos\/logo-euronews-stacked-outlined-72x72-grey-9.svg\" width=\"72\" height=\"72\" alt loading=\"lazy\"><span>ADVERTISEMENT<\/span><\/div>\n<\/div>\n<div class=\"c-ad u-show-for-desktop\">\n<div class=\"c-ad__placeholder\"><img decoding=\"async\" class=\"c-ad__placeholder__logo\" src=\"https:\/\/static.euronews.com\/website\/images\/logos\/logo-euronews-stacked-outlined-72x72-grey-9.svg\" width=\"72\" height=\"72\" alt loading=\"lazy\"><span>ADVERTISEMENT<\/span><\/div>\n<\/div>\n<\/div>\n<p>It is precisely the \u2018social jet lag\u2019 that might be negatively affecting young people\u2019s mental health, a new study by the University of Southampton in the United Kingdom found. And with biological sleep changes occurring in adolescence, addressing youths\u2019 sleep needs and even reconsidering school start times might be a way forward, researchers say. <\/p>\n<p>The review included 12 studies, involving over 230,000 participants, and found that teens experiencing greater levels of \u2018social jet lag\u2019 are more likely to report higher levels of anxiety. It seems to be a vicious circle, as higher anxiety levels also predict greater \u2018social jet lag \u2019, but the authors noted this is an association rather than a proven cause-and-effect relationship. <\/p>\n<p>These findings highlight the importance of behavioural strategies that target healthy, regular sleep as a tool to improve mental health in adolescence, the authors wrote. <\/p>\n<p>Anxiety is already the most common mental health problem among adolescents. The World Health Organization estimates that, globally, 4.4% of 10\u201314-year-olds and 5.5% of 15\u201319-year-olds experience an anxiety disorder \u2013 intense, persistent fear or nervousness that is hard to control. <\/p>\n<p>Worryingly, mental health struggles in adolescence can have impacts later in life, highlighting the need for early identification and intervention. <\/p>\n<div class=\"c-widget-related\" data-stories-id data-event=\"widget_related\">\n<div class=\"c-widget-related__title\"><b class=\"c-widget-related__title__text\" lang=\"en\">Related<\/b><\/div>\n<ul class=\"c-widget-related__list\" id=\"abe-article-related-1\">\n<li class=\"c-widget-related__item\">Experts say the body clock affects heart health.

While it is normally stable throughout life, the authors noted a significant shift towards eveningness in adolescence.<\/p>\n<p>\u201cDuring puberty, the body\u2019s internal clock usually shifts back by a few hours, meaning teenagers naturally don\u2019t start feeling sleepy until later and would ideally wake up later too,\u201d said Sarah Chellappa, a co-author on the paper from the University of Southampton.<\/p>\n<p>\u201cTeenagers also face demands on their time, from early school starts to socialising online, which can rob them of sleep, especially during the week.\u201d<\/p>\n<p>The clash between this preference and early school start times creates a &#8220;perfect storm&#8221; for circadian misalignment, when the internal body clock is mismatched with the outside time. <\/p>\n<p>\u201cIt\u2019s important to look beyond what individuals can do alone and recognise how broader societal systems can influence sleep,\u201d said Hannah Ravenhall, lead author of the paper.<\/p>\n<p>\u201cThis starts with acknowledging the biological sleep changes that occur in adolescence, advocating for their sleep needs, and reconsidering secondary school start times to support young people\u2019s wellbeing.\u201d<\/p>\n<p>The authors wrote that it is important that public health recommendations promote sleep health amongst adolescents and emphasise the importance of consistent sleep timing.<\/p>\n<p>In practice, that could mean schools reconsidering start times and parents rethinking evening screen rules \u2014 small structural changes that, researchers argue, may do more for teenagers&#8217; mental health than simply telling them to &#8220;go to bed earlier.&#8221;<\/p>\n<\/div>\n<p>                                  Go to accessibility shortcuts<\/p>\n<div class=\"c-article-share-comment u-align-items-center u-display-flex\"><span class=\"c-article-share-comment__links u-align-items-center u-display-flex u-justify-content-center js-c-article-share-comment-share\"><span class=\"c-article-share-comment__label\">Share<\/span><\/span><span class=\"c-article-share-comment__label\">Comments<\/span><span class=\"c-article-share-comment__label c-article-share-comment__label--always\">Add Euronews on Google<\/span><\/div>\n<div id=\"adb-article-you-might-also-like\" class=\"perf-cv-auto c-article-you-might-also-like\">\n<h2 class=\"c-article-you-might-also-like__title\">\n        Read more<br \/>\n      <\/h2>\n<div class=\"c-article-you-might-also-like__container\">\n<article id=\"abe-2922744-pos0-c-article-you-might-also-like__item\" class=\"the-media-object m-modeMobile-1 m-modeDesktop-1 m-modeXL-1\" data-nid=\"2922744\" data-cid=\"9899645\" data-part-label=\"Partner content\">\n<figure id=\"abe-2922744-label-pos0-c-article-you-might-also-like__item\" class=\"the-media-object__figure\"><img decoding=\"async\" class=\"the-media-object__image\" src=\"https:\/\/images.euronews.com\/articles\/stories\/09\/89\/96\/28\/480x270_cmsv2_cb7ecd00-a3db-5662-a404-75f5126820a8-9899628.jpg\" loading=\"lazy\" alt=\"file photo\" height=\"9\" width=\"16\"><\/figure>\n<div class=\"the-media-object__content\">\n                    Health news<\/p>\n<h3 class=\"the-media-object__title  \">\n<p>    West Nile virus: 290 cases and 24 deaths in Greece \u2014 Cyprus calls for calm<br \/>\n  <\/h3>\n<\/div>\n<\/article>\n<article id=\"abe-2922583-pos1-c-article-you-might-also-like__item\" class=\"the-media-object m-modeMobile-1 m-modeDesktop-1 m-modeXL-1\" data-nid=\"2922583\" data-cid=\"9898785\" data-part-label=\"Partner content\">\n<figure id=\"abe-2922583-label-pos1-c-article-you-might-also-like__item\" class=\"the-media-object__figure\"><img decoding=\"async\" class=\"the-media-object__image\" src=\"https:\/\/images.euronews.com\/articles\/stories\/09\/89\/87\/85\/480x270_cmsv2_551cc44e-5820-5342-bf24-33274194123e-9898785.jpg\" loading=\"lazy\" alt=\"Among students classified as addicted, 85.3% reported neck pain, compared with 65% of those who were not classified as addicted. \" height=\"9\" width=\"16\"><\/figure>\n<div class=\"the-media-object__content\">\n                    Health news<\/p>\n<h3 class=\"the-media-object__title  \">\n<p>    Back or elbow pain?

many adolescents will struggle with early mornings after a summer of sleeping in and irregular holiday schedules. Throughout the school year, pupils count down to the weekend, hoping to recover the hours of sleep lost during the week \u2014 a pattern researchers call &#8216;social jet lag&#8217;.\u00a0It is precisely the \u2018social jet lag\u2019 that might be negatively affecting young people\u2019s mental health, a new study by the University of Southampton in the United Kingdom found. And with biological sleep changes occurring in adolescence, addressing youths\u2019 sleep needs and even reconsidering school start times might be a way forward, researchers say.\u00a0The review included 12 studies, involving over 230,000 participants, and found that teens experiencing greater levels of \u2018social jet lag\u2019 are more likely to report higher levels of anxiety. It seems to be a vicious circle, as higher anxiety levels also predict greater \u2018social jet lag \u2019, but the authors noted this is an association rather than a proven cause-and-effect relationship.\u00a0These findings highlight the importance of behavioural strategies that target healthy, regular sleep as a tool to improve mental health in adolescence, the authors wrote.\u00a0Anxiety is already the most common mental health problem among adolescents. The World Health Organization estimates that, globally, 4.4% of 10\u201314-year-olds and 5.5% of 15\u201319-year-olds experience an anxiety disorder \u2013 intense, persistent fear or nervousness that is hard to control.\u00a0Worryingly, mental health struggles in adolescence can have impacts later in life, highlighting the need for early identification and intervention.\u00a0Why teenagers&#8217; body clocks shift\u00a0People have a specific chronotype \u2014 whether someone is a morning or an evening person. While it is normally stable throughout life, the authors noted a significant shift towards eveningness in adolescence.\u201cDuring puberty, the body\u2019s internal clock usually shifts back by a few hours, meaning teenagers naturally don\u2019t start feeling sleepy until later and would ideally wake up later too,\u201d said Sarah Chellappa, a co-author on the paper from the University of Southampton.\u201cTeenagers also face demands on their time, from early school starts to socialising online, which can rob them of sleep, especially during the week.\u201dThe clash between this preference and early school start times creates a &#8220;perfect storm&#8221; for circadian misalignment, when the internal body clock is mismatched with the outside time.\u00a0\u201cIt\u2019s important to look beyond what individuals can do alone and recognise how broader societal systems can influence sleep,\u201d said Hannah Ravenhall, lead author of the paper.\u201cThis starts with acknowledging the biological sleep changes that occur in adolescence, advocating for their sleep needs, and reconsidering secondary school start times to support young people\u2019s wellbeing.\u201dThe authors wrote that it is important that public health recommendations promote sleep health amongst adolescents and emphasise the importance of consistent sleep timing.In practice, that could mean schools reconsidering start times and parents rethinking evening screen rules \u2014 small structural changes that, researchers argue, may do more for teenagers&#8217; mental health than simply telling them to &#8220;go to bed earlier.&#8221;\u00a0<\/div>\n<p>[analyse_source url=&#8221;https:\/\/www.euronews.com\/health\/2026\/09\/03\/social-jet-lag-why-mismatched-sleep-schedules-could-be-fuelling-anxiety-in-teenagers&#8221;]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[analyse_image type=&#8221;featured&#8221; src=&#8221;https:\/\/images.euronews.com\/articles\/stories\/09\/89\/87\/91\/1200x675_cmsv2_c6a2f762-38ec-5c3c-b1dd-0cdb939133bc-9898791.jpg&#8221;] Europe News Thousands of Ukrainian children still at risk in Russia Business Series Public-private partnerships open new investment opportunities In partnership with Azpromo Europe News EU suspension of Brazilian meat comes into force, despite negociations Europe News Macron and Burnham hail stronger UK-France ties in first talks Europe News Thousands of Ukrainian [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[90],"tags":[226,36],"class_list":["post-2127205","post","type-post","status-publish","format-standard","hentry","category-international","tag-crawlmanager","tag-euronews-com"],"_links":{"self":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts\/2127205","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2127205"}],"version-history":[{"count":0,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts\/2127205\/revisions"}],"wp:attachment":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2127205"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2127205"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2127205"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
