On-Call Sleep Tips: How to Rest When the Phone Might Ring
Share
On-call sleep tips start with an awkward truth: being on call can hurt your sleep even on nights the phone never rings. The worry about a call, the half-listening for it and the struggle to get back to sleep afterwards all add up. This guide covers why on-call nights feel so draining, how to prepare before a shift, what to do when the call comes, how to get back to sleep afterwards, and how to protect your partner's sleep too.
The short answer: on-call sleep suffers from anticipation as much as from the calls themselves. Lower the worry by setting up a reliable call alert and a ready-to-go routine before bed. When a call wakes you, expect 15 to 30 minutes of grogginess and avoid driving until you've shaken it off. After the call, wind down rather than ramping up, and use light and caffeine carefully if you need to sleep again. Bank sleep before on-call periods and recover afterwards.
Why on-call nights feel so tiring
Sleep researchers have studied on-call work for years, much of it in Australia, and a few findings stand out.
- Anticipation alone disrupts sleep. A 2022 review notes that "anxiety related to the unpredictability of on-call work can affect sleep even if the likelihood of receiving a call is low."
- Getting back to sleep is hard. In one study by the same group, 70% of on-call workers reported difficulty returning to sleep after a call.
- Waking suddenly costs you. Sleep inertia, the grogginess after waking, affects memory, reasoning and reaction time. The worst of it typically lasts 15 to 30 minutes, but full recovery can take over an hour (source).
On-call work is common. One review estimates that between 17% and 25% of the workforce in Australia, the US and Europe has an on-call part to their paid or volunteer role (source). That includes health workers, IT staff, tradies, utility crews and volunteer firefighters.
Before an on-call shift
The aim is to go to bed confident that you won't miss a call, so your brain can let go.
- Bank sleep in the days before. Go to bed on time, and add a nap if your next stretch looks busy.
- Test your call alert. Make sure the phone or pager is charged, the volume or vibration is on, and Do Not Disturb settings let calls through.
- Put the phone in one place. Same spot every night, within reach, charger plugged in.
- Lay out what you'll need. Clothes, keys, ID, laptop. Fewer decisions while groggy.
- Keep the usual wind-down. A consistent bedtime routine helps more than staying up "in case". See bedtime routine for adults.
- Watch the caffeine. The Sleep Health Foundation notes its effects can last several hours, often longer than you think (source).
When the call comes
The first few minutes after waking are when mistakes happen.
- Sit up, lights on, feet on the floor. Give yourself a moment before making decisions.
- Write things down. Your memory is weaker in the first stretch after waking.
- Avoid driving straight away if you can. The Sleep Health Foundation advises avoiding high-risk tasks like driving or operating machinery during sleep inertia. If you must drive, take a few minutes to wake up properly first. See what is sleep inertia.
- Know your own pattern. Some people wake sharp; others need longer. Plan around the slower version of yourself.
Getting back to sleep after a call
Researchers describe on-call work as needing two skills: switching on during a callout and switching off after it. The 2022 review points out that tools to wake you up, like caffeine, bright light and exercise, may make it harder to sleep again, and advises being strategic with them when you know you'll need to sleep after the call.
| Situation | What helps |
|---|---|
| Quick phone call from bed | Keep lights low, screen brightness down, back to bed straight away |
| Short callout, back home by midnight | Skip caffeine, dim lights at home, short wind-down |
| Long callout, home near dawn | Dark room, eye mask, accept a shorter sleep and nap later |
| Busy night, early start next day | Talk to your manager about a later start if fatigue is high |
| Mind racing after a hard call | Write it down, slow breathing, see racing thoughts at night |
If you're lying awake for a long time, some people find it easier to get up, keep the lights low and do something quiet until they feel sleepy, rather than watching the clock.
Protecting your partner's sleep
On-call work affects the household too. A review of on-call work and partners found that partners reported their own sleep was disturbed, felt more tired the next day, and often took on extra household jobs while the worker was on call or recovering (source).
- Keep the call alert close to you, not on a shared bedside table.
- Get dressed outside the bedroom if your clothes are ready in another room.
- Talk about on-call weeks in advance, so your partner can plan their own sleep. See wake up without waking your partner and living with a shift worker.
When to see your GP
If on-call work leaves you exhausted most days, you're dozing off at the wheel, or anxiety about calls is stopping you sleeping on nights off too, see your GP. This guide is general information, not medical advice.
Where the Sovune Nudge fits
We make the Sovune Nudge, a silent alarm wristband, so we're not neutral. It doesn't receive calls, so it can't replace your phone or pager on call. Where it helps is the scheduled wake-up: your normal morning alarm, or the alarm for the end of a nap between calls, without waking your partner.
- Silent. No speaker and no sound, so only you notice it.
- Wakes you with vibration on your wrist, starting as a gentle tap and building through three intensity levels. Each alarm lasts a full minute, and you can switch it off sooner.
- Three separate alarms, handy for a nap alarm and a morning alarm on the same day.
- Set on the band itself. No app, no phone, no Bluetooth.
It comes with a 30-day money-back guarantee.
Quick answers
Why do I sleep badly on call even when no one calls? Anticipating a call can raise anxiety and lighten your sleep, even when calls are unlikely.
How long does grogginess last after a call? The worst usually lasts 15 to 30 minutes, though full recovery can take more than an hour.
Should I have coffee during a night callout? It may help you function, but it can make it harder to sleep afterwards. Use it only if you won't need to sleep again soon.
Can a vibrating wristband replace my on-call phone? No. Keep your phone or pager for calls and use a wrist alarm for scheduled wake-ups.
