Going to bed for a 3:22 am alarm

  • Asleep by 6:07 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 7:37 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 9:07 pm — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

How to use the online alarm clock

As you hand over the last household responsibility to someone else before leaving for an NHS night shift, set the alarm for 3:22 am and keep your uniform, pass and keys together. That leaves a useful window before 4:00 am for getting dressed, checking your route and reaching the ward without turning the departure into a rush.

Your NHS departure plan relies on the alarm remaining active after you set 3:22 am, so leave this page running while you prepare. If you close the browser, the alarm cannot sound to get you moving for the night shift; it also cannot alert you if the phone or computer goes to sleep. Keep the sound audible, connect the charger if the battery is low, and check that silent mode will not interfere. A separate phone alarm is sensible if you might shut the page.

Before stepping outside for the shift, notice how warm the room feels after spending time near heating or air conditioning. At this hour, strong air conditioning can make a mild British night feel unexpectedly warm when you leave, while summer heat may linger indoors. Put any extra layer where you can reach it, take some water, and allow your glasses a moment to clear if the change in temperature causes condensation.

Common questions

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 3:22 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
