Where should you start with a short daytime nap?
Your eyes are closing in the afternoon, but you do not want to struggle with sleep that evening. When planning a nap, consider where it fits in your day and what you will do afterwards, as well as how long it lasts.
NHLBI's general sleep habits guide recommends keeping adult naps short, no longer than 20 minutes. For people who struggle to fall asleep at night, it suggests limiting naps or taking them earlier in the afternoon.
This article offers an everyday break plan for adults who sleep at night. Children's sleep needs and shift workers' routines differ. Rather than following a rule that everyone must nap, notice how it fits your own day.
Where should a nap fit into your day?
Start with your day's outline: when does work or study finish, when do you get home and when do you plan to go to bed? Accidentally sleeping on the sofa for a long time in the evening is different from setting aside a brief earlier break.
If you can take a short rest during lunch, leave time for getting ready and recovering afterwards too. If your entire break is only 20 minutes, trying to use all of it for sleep and rush into a meeting at the last second may not feel comfortable. If there is no suitable time or space, you could choose a quiet break without sleeping. Think of it as a personal way to rest during the day, without assuming it has the same effect as sleep.
If falling asleep at night is already difficult, review your routine before adding more daytime sleep. NHLBI's insomnia treatment guide advises avoiding naps, particularly in the afternoon, for people in that situation. General nap advice and insomnia advice differ because the starting need is different.
Plan your break in three parts
The sequence below is an example for designing a rest break that suits you. It is not a fixed treatment programme or a daily task list you must complete.
Preparation: decide when you need to return
- Check when your next responsibility begins.
- Set a reliable alarm.
- If people need to reach you, choose notification settings that allow important calls through.
- Prepare a space where your head and neck feel comfortable.
Rest: make a small, practical space
At home, arrange the curtains and seating for your own comfort. In a shared space, talk with the people around you. Preparing so you do not need to keep checking how many minutes remain can make the break easier.
If you cannot use the same space every time, identify the portable parts of your routine: adjusting notifications, setting the alarm and finding a quiet corner. This helps keep preparing for a break from becoming a long task itself.
Returning: leave room before your next task
Notice how you feel when you wake, rather than moving straight into the next task. Allow time to get up, tidy the space and prepare for what comes next. An alarm sounding does not necessarily mean your attention has fully recovered that instant.
Why might you feel groggy after waking?
CDC/NIOSH calls temporary grogginess after waking “sleep inertia”. Reaction and thinking speed may be slower for a while. Its duration varies with the person and circumstances, and recovery may take longer when sleep loss has built up.
For this reason, avoid planning driving or tasks requiring safety-critical attention immediately after your nap. NIOSH recommends allowing time for the effects to pass before critical tasks. Check your alertness instead of assuming a short nap means you are immediately ready.
For someone working from home, this could mean leaving a few preparation minutes after the break. For someone who needs to drive, it means not setting off while still sleepy. Build your rest plan around the level of attention your next task requires.
How can you notice whether a nap suits you?
For a few days, make short notes under just three headings:
- The time and approximate length of the break. Even “after lunch, a short sleep” is a useful start. Add a time if you remember it.
- How you felt after waking. Choose your own words, such as more refreshed, much the same or noticeably groggy.
- The transition to night-time sleep. Did it feel easier, similar or harder than usual?
Feeling good on one day does not give a definite answer on its own. Consider that day's workload, coffee timing and the previous night too. At the end of the week, read the notes together and choose an arrangement you can maintain. This record is not proof of a cause; it is a tool for considering everyday choices more thoughtfully.
If you often feel you have to sleep during the day or doze off unintentionally, look beyond the break habit itself. NHLBI includes difficulty staying awake during ordinary tasks among the information considered in a sleep assessment. Share that experience with your family doctor or primary care clinician.
Frequently asked questions
Do I need to nap every day?
No. If you feel well during the day, you do not need to add sleep simply because you saw a recommendation. Consider rest alongside your daily needs and night-time routine.
Will I definitely feel refreshed after 20 minutes?
Keeping naps short is general guidance, not a guarantee of a particular feeling. Leave yourself time before returning to your next task.
I fall asleep in front of the television in the evening. What could I change?
First, notice when it happens and for how long. To close your evening more deliberately, try the short preparation sequence in our sleep routine guide.
How should I prepare a resting space?
Consider a comfortable level of light and sound, a safe place to get up and your notifications. Our room checklist can help you choose small adjustments at home.
