Powering Nike athletes on soccer's biggest stage

Nike has included subscriptions to Timeshifter’s jet lag app in their 2026 World Cup Performance Pack, giving Nike-sponsored teams and players a science-based way to adjust to new time zones quickly.

Playing in the World Cup creates a unique performance challenge. Players arrive from clubs and countries all over the world, crossing multiple time zones just to reach the tournament. Then matches are spread across the U.S., Mexico, and Canada. When it's over, some face a long journey home, and even after the World Cup, most players travel between club seasons, internationals, and tournaments.

Every trip crossing time zones disrupts the body's circadian clocks. These circadian clocks regulate nearly every system in our brain and body, including sleep, alertness, performance, mood, immune response, metabolism, and heart, lung, and muscle function. Research consistently links circadian disruption with impaired reaction time, reduced endurance, poor decision-making and concentration, and increased risk of injury.

Nike also brought Timeshifter to the 2026 Winter Olympics in Milan-Cortina, to help its athletes tackle jet lag and align their circadian peak with competition times.

Circadian rhythms have always mattered in elite sport. What's new is the advances in circadian science and Timeshifter's technology to control them – a new competitive edge for athletes.

Jet lag is history.

Timeshifter's jet lag app is the most downloaded and highest-rated jet lag app in the world. Get personalized jet lag plans based on your sleep pattern, chronotype, itinerary, and personal preferences.
