Some days, you just really need to take a nap! We’ve all been there, when the exhaustion hits, and you just need to catch a quick snooze for a little energy boost to get through the rest of the day (that post-lunch energy slump can be REAL).

But before taking a nap, make sure that your nap routine won’t mess up your nighttime sleep! Learn the risks and benefits of naps below.

Advantages of Daytime Naps

Boosted performance
When your nap is kept short (20—30 minutes long), it can help to improve focus, alertness, and mental performance.

Helps you to think outside the box
If you’re needing a little creativity lift or a spark to help you problem-solve, a nap may be the answer!

Stress reduction and improved emotional well-being
Taking a nap can help to regulate your mood and reduce feelings of stress, anxiety and depression.

Disadvantages of Daytime Naps

May make you feel worse
You may experience something called ‘sleep inertia’ which can make you feel groggy, disoriented, and a bit “off” after waking. Some people do experience this after a nap, particularly if they’ve slept for too long (over 30 minutes).

Can impact your nighttime sleep
If you nap for too long, or too late in the day, this can interrupt your circadian rhythm and the sleep drive that naturally builds up during the day to make you feel tired enough for sleep at nighttime.

May reinforce sleep issues
If there’s a reason you’re experiencing persistent daytime sleepiness (e.g., a sleep disorder), having a daily nap may contribute to a vicious cycle where you become dependent on the extra sleep.

Long naps may be linked to health issues
Studies have found that daily naps over an hour long may be linked to type 2 diabetes.

Tips for Positive Napping

While there’s no denying that naps can be beneficial for many of us, there are a few actions and precautions you can take to ensure your daytime naps are having a healthy impact.

Try to keep these things in mind when you’re considering your next nap:

Keep your nap brief
Try to cap your nap at 20-30 minutes (set an alarm if you need to). Napping too long can leave you feeling groggy and may interfere with your nighttime sleep.

All about timing
When it comes to naps, timing is everything. If you nap too late in the day, this may affect your ability to sleep well at night. The early afternoon is the best time to take a nap (and combat that after-lunch slump I mentioned earlier). Try to avoid naps within 8 hours of bedtime.

Consider your sleep environment
Your nap should be short, but that doesn’t mean it needs to be poor quality. If you can, opt for a dark, cool space that’s comfortable and free from distractions. If you’re napping at work during the day, an eye mask can help shut out the light and signal to your body that it’s time to rest. Ear plugs can be helpful in noisier environments, but keep in mind that if you’ve set an alarm, ear plugs may prevent you from hearing it! If ear plugs are important and you own a smartwatch, consider using a smartwatch alarm which vibrates to wake you.

Tune into your body
If you’re finding you’re regularly tired during the day, this may be a sign that you’re not getting enough sleep at night. It may also indicate that the quality of your sleep overnight isn’t as good as it should be. If this is the case, reassess your nighttime sleep hygiene and optimize your sleep space.

If ongoing fatigue is becoming a concern, and you’re needing to nap every day, then it’s important to chat with your doctor to rule out any other health concerns or contributing factors.

Should I Take a Daytime Nap?

Ultimately, the choice is yours! Naps can be a fantastic way to combat stress and fatigue while enhancing your performance, creativity and ability to problem solve. However, your nighttime sleep should still be the priority, so it’s vital that you exercise caution around the timing and length of any daytime sleep so as to not interrupt your internal body clock.
