Set the timer to 37 seconds

How to use the online timer

Cold exposure only needs to be brief to count, and 37 seconds is a realistic target if you're easing into cold showers or a quick ice bath rather than chasing a personal record. Start the clock as soon as the cold hits, breathe through it instead of watching the screen, and get out the second it beeps. Short, sharp, and over before your brain talks you out of it.

Hit Start whenever you're ready and the timer runs on its own from there, no further clicking required until it finishes. It only counts while the tab stays open, so leave it running in the background rather than closing the browser or navigating away if you need the time to stay accurate. Once it reaches zero, an alarm sound lets you know without you having to keep checking the page.

A phone timer works fine until a call comes in or a notification steals the screen at the worst moment. Running it in a browser tab keeps it separate from all that, ticking away quietly in the background of your computer or phone without competing for attention until it's done. There's nothing to install and nothing to sign up for, just a page that does one job well. Set a timer for 37 seconds, set the timer to 37 seconds, start a 37 seconds timer — it is the same countdown either way.

Common questions

Can I set a custom time instead of the preset?

Yes, most pages let you adjust the minutes and seconds directly, so you're not limited to the exact length shown in the page title.

Does the timer work without an internet connection?

The page needs to load once, but the countdown itself runs locally in your browser, so a dropped connection partway through won't stop it.

Will the timer still run if my laptop goes to sleep?

No, if the device sleeps or the browser is suspended, the countdown pauses along with it, so keep your screen awake for an accurate result.

Is there a cost to use the timer?

No, it's free to use, with no registration, sign-up, or hidden limit on how many times you can run it.
