Jam ini bergeser sekitar <strong>1 jam per hari saat Anda terbang ke timur<\/strong> dan sekitar <strong>1,5 jam per hari saat Anda terbang ke barat<\/strong> \u2013 itulah sebabnya terbang ke timur biasanya terasa lebih berat.<\/p><p>Cahaya adalah sinyal terkuat untuk mengatur ulang jam biologis. Cahaya pada jam-jam <em>setelah<\/em> titik suhu tubuh terendah Anda (sekitar dua jam sebelum waktu bangun normal) memajukan jam Anda; cahaya pada jam-jam <em>sebelum<\/em> titik itu memundurkannya. Rencana di atas mengatur waktu terang dan gelap agar jam Anda bergeser ke arah yang benar \u2013 dan memperingatkan Anda jika cahaya pagi justru akan mendorongnya ke arah yang salah setelah penerbangan jauh ke timur.<\/p><h2>Tips singkat<\/h2><ul><li>Geser waktu tidur Anda 1 jam per hari mendekati waktu tujuan selama 2\u20133 hari sebelum terbang.<\/li><li>Minum air dan batasi alkohol serta kafein di pesawat.<\/li><li>Setibanya di tujuan, makanlah sesuai waktu setempat dan batasi tidur siang di bawah 30 menit.<\/li><\/ul><\/div><\/section><section class=\"wc-section wc-faq\"><h2>Pertanyaan yang sering diajukan<\/h2><details><summary>Berapa lama jet lag berlangsung?<\/summary><p>Sebagai patokan, sekitar satu hari untuk setiap zona waktu yang dilintasi saat terbang ke timur, dan sedikit lebih singkat \u2013 sekitar dua hari untuk setiap tiga zona waktu \u2013 saat terbang ke barat.<\/p><\/details><details><summary>Apakah jet lag lebih berat saat terbang ke timur atau ke barat?<\/summary><p>Ke timur. Terbang ke timur berarti Anda harus tidur lebih awal daripada yang diinginkan tubuh, dan jam biologis lebih lambat untuk maju daripada mundur.<\/p><\/details><details><summary>Apakah jet lag terjadi pada penerbangan utara\u2013selatan?<\/summary><p>Tidak. Jet lag muncul karena melintasi zona waktu. Penerbangan panjang dari Eropa ke Afrika Selatan memang melelahkan, tetapi hampir tidak menimbulkan jet lag karena selisih waktunya hanya satu atau dua jam.<\/p><\/details><\/section><section class=\"wc-section wc-tools-grid\"><div class=\"wc-section__head\"><h2>Alat waktu gratis lainnya<\/h2><a href=\"https:\/\/www.worldclock.com\/id\/alat-waktu\/\">Semua alat \u2192<\/a><\/div><div class=\"wc-toolcards\"><a class=\"wc-toolcard wc-toolcard--hours\" href=\"https:\/\/www.worldclock.com\/id\/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 di antara dua waktu.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--timecard\" href=\"https:\/\/www.worldclock.com\/id\/kalkulator-kartu-absensi\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\uddc2\ufe0f<\/span><span class=\"wc-toolcard__name\">Kalkulator Kartu Absensi<\/span><span class=\"wc-toolcard__desc\">Jam kerja mingguan, lembur &amp; upah.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--decimal\" href=\"https:\/\/www.worldclock.com\/id\/konversi-jam-desimal\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udd22<\/span><span class=\"wc-toolcard__name\">Konversi Waktu Desimal<\/span><span class=\"wc-toolcard__desc\">Jam:menit \u21c4 desimal.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--pomodoro\" href=\"https:\/\/www.worldclock.com\/id\/timer-pomodoro\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83c\udf45<\/span><span class=\"wc-toolcard__name\">Timer Pomodoro<\/span><span class=\"wc-toolcard__desc\">Sesi fokus 25 menit.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--sleep\" href=\"https:\/\/www.worldclock.com\/id\/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\/id\/jam-buka-bursa-saham\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udcc8<\/span><span class=\"wc-toolcard__name\">Jam Bursa Saham &amp; Jam Kerja<\/span><span class=\"wc-toolcard__desc\">Apakah pasar sedang buka?<\/span><\/a><a class=\"wc-toolcard wc-toolcard--bell\" href=\"https:\/\/www.worldclock.com\/id\/hitung-mundur-bursa-saham\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udd14<\/span><span class=\"wc-toolcard__name\">Hitung Mundur Bursa Saham<\/span><span class=\"wc-toolcard__desc\">Hitung mundur ke bel pembukaan.<\/span><\/a><a class=\"wc-toolcard wc-toolcard--converter\" href=\"https:\/\/www.worldclock.com\/id\/konversi-zona-waktu\/\"><span class=\"wc-toolcard__icon\" aria-hidden=\"true\">\ud83d\udd01<\/span><span class=\"wc-toolcard__name\">Konversi Zona Waktu<\/span><span class=\"wc-toolcard__desc\">Konversi waktu antar kota mana pun.<\/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-35496","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\/id\/author\/clocker\/"},"comment_info":"","_links":{"self":[{"href":"https:\/\/www.worldclock.com\/id\/wp-json\/wp\/v2\/pages\/35496","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.worldclock.com\/id\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.worldclock.com\/id\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.worldclock.com\/id\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.worldclock.com\/id\/wp-json\/wp\/v2\/comments?post=35496"}],"version-history":[{"count":0,"href":"https:\/\/www.worldclock.com\/id\/wp-json\/wp\/v2\/pages\/35496\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.worldclock.com\/id\/wp-json\/wp\/v2\/media?parent=35496"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
