Set the timer to 47 seconds

How to use the online timer

Cold exposure only needs to be brief to count, and 47 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.

Using it is as simple as it sounds: hit Start and the countdown takes over from there. Keep the browser tab open while it runs, since the timer only keeps counting while the page stays loaded, and pause or reset it any time if your plans change. When time's up, a sound plays to let you know, so you don't need to keep glancing at the screen.

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 47 seconds, set the timer to 47 seconds, start a 47 seconds timer — it is the same countdown either way.

Common questions

Can I pause the timer partway through?

Yes, pause and resume are both available, so you can stop the count if you're interrupted and pick up again exactly where you left off.

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.
