Ia beranjak kira-kira <strong>1 jam sehari apabila anda terbang ke timur<\/strong> dan kira-kira <strong>1.5 jam sehari apabila anda terbang ke barat<\/strong> \u2013 sebab itulah terbang ke timur biasanya terasa lebih teruk.<\/p><p>Cahaya ialah isyarat paling kuat untuk menetapkan semula jam badan. Cahaya pada jam-jam <em>selepas<\/em> titik suhu terendah badan anda (kira-kira dua jam sebelum waktu bangun biasa) menganjakkan jam anda lebih awal; cahaya pada jam-jam <em>sebelum<\/em> titik itu menganjakkannya lebih lewat. Pelan di atas menetapkan masa cahaya dan gelap supaya jam anda beranjak ke arah yang betul \u2013 dan memberi amaran apabila cahaya pagi akan menolaknya ke arah yang salah selepas penerbangan jauh ke timur.<\/p><h2>Petua ringkas<\/h2><ul><li>Anjakkan waktu tidur anda 1 jam sehari ke arah waktu destinasi selama 2\u20133 hari sebelum terbang.<\/li><li>Minum air dan kurangkan alkohol serta kafein dalam pesawat.<\/li><li>Semasa tiba, makan mengikut waktu tempatan dan hadkan tidur sekejap kepada kurang 30 minit.<\/li><\/ul><\/div><\/section><section class=\"wc-section wc-faq\"><h2>Soalan lazim<\/h2><details><summary>Berapa lamakah jet lag berlarutan?<\/summary><p>Sebagai panduan umum, kira-kira satu hari bagi setiap zon waktu yang dilalui apabila terbang ke timur, dan sedikit kurang \u2013 kira-kira dua hari bagi setiap tiga zon waktu \u2013 apabila terbang ke barat.<\/p><\/details><details><summary>Adakah jet lag lebih teruk apabila terbang ke timur atau ke barat?<\/summary><p>Ke timur. Terbang ke timur bermaksud anda perlu tidur lebih awal daripada yang dikehendaki badan, dan jam badan lebih perlahan untuk dimajukan berbanding dilewatkan.<\/p><\/details><details><summary>Adakah jet lag berlaku dalam penerbangan utara\u2013selatan?<\/summary><p>Tidak. Jet lag berpunca daripada melintasi zon waktu. Penerbangan panjang dari Eropah ke Afrika Selatan menyebabkan keletihan tetapi sedikit atau tiada jet lag kerana perbezaan waktunya hanya sejam atau dua.<\/p><\/details><\/section><section class=\"wc-section wc-tools-grid\"><div class=\"wc-section__head\"><h2>Lebih banyak alat waktu percuma<\/h2><a href=\"https:\/\/www.worldclock.com\/ms\/alat\/\">Semua alat \u2192<\/a><\/div><div class=\"wc-toolcards\"><a class=\"wc-toolcard wc-toolcard--hours\" href=\"https:\/\/www.worldclock.com\/ms\/kalkulator-jam\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\u231b<\/span><span class=\"wc-toolcard__name\">Kalkulator Jam<\/span><span class=\"wc-toolcard__desc\">Jam antara dua masa.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--timecard\" href=\"https:\/\/www.worldclock.com\/ms\/kalkulator-kad-waktu\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\uddc2\ufe0f<\/span><span class=\"wc-toolcard__name\">Kalkulator Kad Waktu<\/span><span class=\"wc-toolcard__desc\">Jam mingguan, lebih masa &amp; bayaran.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--decimal\" href=\"https:\/\/www.worldclock.com\/ms\/penukar-jam-perpuluhan\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udd22<\/span><span class=\"wc-toolcard__name\">Penukar Masa Perpuluhan<\/span><span class=\"wc-toolcard__desc\">Jam:minit \u21c4 perpuluhan.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--pomodoro\" href=\"https:\/\/www.worldclock.com\/ms\/pemasa-pomodoro\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83c\udf45<\/span><span class=\"wc-toolcard__name\">Pemasa Pomodoro<\/span><span class=\"wc-toolcard__desc\">Sesi fokus 25 minit.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--sleep\" href=\"https:\/\/www.worldclock.com\/ms\/kalkulator-tidur\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\ude34<\/span><span class=\"wc-toolcard__name\">Kalkulator Tidur<\/span><span class=\"wc-toolcard__desc\">Waktu tidur &amp; bangun terbaik.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--markets\" href=\"https:\/\/www.worldclock.com\/ms\/waktu-pasaran-saham\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udcc8<\/span><span class=\"wc-toolcard__name\">Waktu Pasaran Saham &amp; Perniagaan<\/span><span class=\"wc-toolcard__desc\">Adakah pasaran dibuka sekarang?<\/span><\/a><a class=\"wc-toolcard wc-toolcard--bell\" href=\"https:\/\/www.worldclock.com\/ms\/kira-detik-pasaran-saham\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udd14<\/span><span class=\"wc-toolcard__name\">Kira Detik Pasaran Saham<\/span><span class=\"wc-toolcard__desc\">Kira detik ke loceng pembukaan.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--converter\" href=\"https:\/\/www.worldclock.com\/ms\/penukar-zon-waktu\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udd01<\/span><span class=\"wc-toolcard__name\">Penukar Zon Waktu<\/span><span class=\"wc-toolcard__desc\">Tukar waktu antara mana-mana bandar.<\/span><\/a><\/div><\/section><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":"","bs_cache_bypass_cache":0,"bs_cache_related_page":0},"class_list":["post-62664","page","type-page","status-publish","hentry"],"acf":[],"taxonomy_info":[],"featured_image_src_large":false,"author_info":{"display_name":"clocker","author_link":"https:\/\/www.worldclock.com\/ms\/author\/clocker\/"},"comment_info":"","_links":{"self":[{"href":"https:\/\/www.worldclock.com\/ms\/wp-json\/wp\/v2\/pages\/62664","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.worldclock.com\/ms\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.worldclock.com\/ms\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.worldclock.com\/ms\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.worldclock.com\/ms\/wp-json\/wp\/v2\/comments?post=62664"}],"version-history":[{"count":0,"href":"https:\/\/www.worldclock.com\/ms\/wp-json\/wp\/v2\/pages\/62664\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.worldclock.com\/ms\/wp-json\/wp\/v2\/media?parent=62664"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
