Why Can't I Sleep After a Game or Race?

Last updated: August 2026 · Written by Arun Menon with the Reincarn Science Team

You emptied the tank, you are exhausted, and yet you lie in bed at 1am wide awake, replaying the game. Post-competition insomnia is one of the most common and least discussed problems in sport. Here is why it happens and how to switch off after you compete.

Why can't you sleep after competing?

Because competition leaves the body in a state of physiological arousal, raised stress hormones, adrenaline, heart rate and temperature, that must come down before sleep can begin. Sleep requires the nervous system to shift from alert to rest, and a hard competition does the opposite, keeping stress hormones and the sympathetic system elevated well into the night (Vgontzas et al., 2001). The exhaustion is real, but arousal is overriding it. See why arousal blocks sleep.

What keeps you wired after a game?

A combination of adrenaline and cortisol, a raised core temperature, late finishes and bright lights, caffeine or pre-workout, and the mental replay of the event. Evening and night competition stack several sleep disruptors at once: intense late exercise can delay sleep onset, and stadium lights, travel and stimulants compound it (Stutz et al., 2019; Vitale et al., 2019). Rumination on the result adds mental arousal on top. See how to lower cortisol before bed.

Is post-competition insomnia normal?

Yes, it is a common and expected response to hard competition, not a sleep disorder, though repeated nights of it can accumulate a real deficit. Athletes routinely report disturbed sleep after evening games and events, and reviews treat it as a known challenge of competition schedules rather than pathology (Fullagar et al., 2015; Charest and Grandner, 2020). The concern is only if it becomes a chronic pattern. See why chronic poor sleep raises injury risk.

How do you wind down after a night game?

Cool down gradually, lower light and screens, delay or skip late caffeine, refuel and rehydrate, and give yourself a real buffer before trying to sleep. The goal is to decelerate rather than slam from full effort to lights-out. A cool-down, a warm shower that then lets you cool, dim light and a calm routine all help arousal fall, in line with athlete sleep-hygiene guidance (Vitale et al., 2019). See how to sleep after an evening workout.

What if you still cannot sleep?

Do not force it; get up, keep lights low and do something calm, and return to bed when sleepy, then protect the following night to recover. Trying harder raises arousal, which is exactly what is keeping you awake. Accept a rougher night after a big event, and prioritise the next night's sleep to clear the deficit. See a recovery-first routine.

Frequently asked questions

Why can't I sleep after a big game or race?

Competition leaves your body aroused, with elevated adrenaline, cortisol, heart rate and temperature, which must come down before sleep. The exhaustion is real but arousal overrides it.

Is it normal to have insomnia after competing?

Yes. Post-competition insomnia is a common, expected response to hard effort and late events, not a disorder. It only becomes a concern if it turns into a chronic pattern.

How do I calm down and sleep after a night game?

Cool down gradually, lower light and screens, delay or skip late caffeine, refuel, and give yourself a real buffer before bed so arousal can fall.

Should I force myself to sleep if I can't?

No. Forcing it raises arousal. Get up, keep the lights low, do something calm, and return when sleepy, then protect the next night to recover.
