past<\/a> \u2014 and his NASA-used technology is so popular that even World Cup teams such as England and France have relied on the app to stay energized.<\/p>\n<p>Mickey Beyer-Clausen, the son of a flight attendant, built his Timeshifter app for travelers such as himself to input their sleep preferences easily, then receive a readout of when to stay awake, snooze and even consume caffeine for energy while adapting to a time zone.<\/p>\n<p>\u201cThe whole body is struggling and misaligned, the Southampton resident said of the switch-over to different time zones. <\/p>\n<figure

work.\u201d<\/p>\n<p>For one thing, jet lag can\u2019t just be slept off, said Beyer-Clausen, 51, who was born in a fishing village north of Copenhagen, Denmark.<\/p>\n<aside class=\"single__inline-module aligncenter wp-block-nypost-editor-primary-tag\">\n<\/aside>\n<p>\u201cIt has no scientific evidence behind it,\u201d he said of the popular supposed remedy.<\/p>\n<p>His 2018-launched app was co-founded by NASA-tied Harvard Medical School scientist Dr. Steven Lockley \u2014 and based on technology that helped astronauts sleep properly onboard the International Space Station.<\/p>\n<p>A core part of the app \u2014 the most popular of its kind with nearly 2 million subscribers \u2014 is guiding travelers on the exact amount of time and which hours of the day they should spend in bright or dark environments to keep up with their typical routine.<\/p>\n<figure class=\"nyp-slideshow-modal-image wp-block-image aligncenter size-large\"><figcaption>Timeshifter lets users know when they should stay awake or sleep when adjusting to a new time zone. <span class=\"credit\">Stefano Giovannini for NY Post<\/span><\/figcaption><\/figure>\n<p>\u201cThat is the most powerful signal we can send to the body to manipulate, shift, and control adjusting quicker to the new time zone,\u201d he said.<\/p>\n<p>Beyer-Clausen said dark sunglasses are the \u201cNo. 1\u201d carry-on item so travelers always have a way to simulate dark environments when needed \u2014 even if it means wearing them on a bright plane or indoors.\u00a0<\/p>\n<p>Timeshifter also hand-tailors its guidance based on an individual\u2019s sleep preferences and peak energy times, a pattern known as a person\u2019s chronotype, including by changing slumber patterns in the days leading up to a trip.\u00a0<\/p>\n<figure class=\"nyp-slideshow-modal-image wp-block-image aligncenter size-large\"><figcaption>The app creates a schedule for travelers to follow. <span class=\"credit\">Stefano

beating jet lag, as each person\u2019s chronotype greatly varies, but early birds typically do better while traveling east and night owls west, Beyer-Clausen said.<\/p>\n<p>Lufthansa embraced the value in Timeshifter when more than 150 of its employees downloaded the app, leading to a partnership between the two.\u00a0<\/p>\n<p>Nike recently also rolled out a collaboration offering it to its sponsored athletes on the World Cup teams from France, England, Brazil, Norway, the Netherlands and even<a

science purposes, he said.<\/p>\n<p>\u201cWhen we work with a team, they\u2019re curious what games are problematic for them,\u201d Beyer-Clausen said.<\/p>\n<p>\u201cWe can just outline them and say, \u2018Here you have a 74% chance of losing or winning based on circadian rhythm.\u201d\u00a0<\/p>\n<p>Timeshifter, which will be used again by Nike for the<a href=\"https:\/\/nypost.com\/2026\/07\/14\/lifestyle\/olympics-organizers-blasted-for-not-paying-60000-volunteers\/\"> 2028 Olympic Games in Los Angeles<\/a>, is poised to make much more noise \u2014 and big bucks \u2014 in the sports scene as reliable data continues to emerge.<\/p>\n<p>\u201cI can tell you that the revenue I budgeted for 2026 in terms of the concierge services we do for athletes \u2014 I reached that on the 15th of January this year,\u201d Beyer-Clausen said.<\/p>\n<\/p><\/div>\n<script async=\"async\" data-cfasync=\"false\"
