Dear Alice,

Some roommates of mine and I have been thinking about sleeping lately.

Usually we're all told to get eight to nine hours of sleep, and a lot of the time we do! The problem is, once in a while, when there's an essay to write or exam to study for, I or my friends may end up having no choice but to be up until 6 in the morning. No one's really explained what the best thing is to do if you have to be up.

What would you suggest? Should we eat? Take a quick nap before class, sleep during the afternoon or wait until evening? Any suggestions you have would be great.

Dear Reader, 

Although it may be tempting to burn the midnight oil before a big exam to cram in as much information as possible, you might not be getting the benefits of all that work. When it comes to recalling information and performing well, having adequate sleep leading up to an exam is key. Sleep is also crucial to good mental and physical health, both of which are factors that also influence academic performance. Because of that, whenever possible, it may be more beneficial to focus on nighttime sleep instead of staying up to study or do other work. However, even with the best planning, sometimes there are situations where students end up losing sleep over assignments. Read on for strategies to maximize your sleep while meeting deadlines. 

Sleep is often the first sacrifice when life becomes busy and stressful, but even a consistent loss of just an hour or two of sleep can have adverse effects. Research shows that students who pull an all-nighter or decrease their sleep time by just a few hours are less likely to perform well on a next-day exam compared to students who slept the recommended seven to nine hours. With this in mind, all-nighters may be better suited for finishing an assignment or writing an essay (i.e., something that doesn't require memory and recall the next day); though staying up all night to finish an assignment is probably still best kept as a final resort. Having proper sleep each night not only allows you to learn and retain important information better, but also aids physical health by regulating hormones and supporting your immune system. There are various documented impacts of sleep deprivation further supporting the importance of sleep. 

Understandably, there may be rare occasions when you're faced with an all-nighter and sleeping a full night isn't an option. If this scenario can't be avoided, here are some tips for maximizing your study, sleep, and recovery time: 

  • Prioritize sleep: If you know in advance that you may need to stay up late to study or work, you might try to prioritize sleep on the days leading up to the late-night study session. 
  • Let there be light: Staying in well-lit rooms while studying can help to keep you alert and awake. Begin turning the lights down as it gets closer to bedtime and when you’re ready to turn in for the night, try to keep your sleeping area dark or use a sleep mask. 
  • Caffeine crutch: If caffeine is your thing, remember that a little bit can go a long way. It's best to sip a small amount of coffee, tea, or other caffeine-containing drinks over a longer period of time rather than chugging it all at once. This is because drinking caffeine quickly has the potential to cause a caffeine crash.  Although it’s typically recommended that caffeine consumption be avoided starting in the late afternoon—around eight hours before bedtime—in order to minimize its impact on your sleep, that can be challenging when you’re trying to use the caffeine to stay awake and study. That said, the way that caffeine affects the body can differ from person to person so timing your caffeine intake to align with when you think you’ll be studying and minimizing consumption throughout the session may help sleep come a little easier when you’re done for the night. Drinking a glass of cold water can also serve as a good pick-me-up without having the longer lasting impacts of caffeine. 
  • Power naps: Short naps, ideally 15 to 20 minutes, may also be energizing. A nap that is longer than 30 minutes may lead to temporary mental confusion and impaired performance in learning and reasoning. These naps can be taken just before or during your all-nighter. 
  • Break time: Like with any type of study session, taking periodic breaks can help with alertness. Breaks should involve something stimulating, like walking or stretching. 
  • Fuel up for productivity: Eating foods with plenty of nutrients and avoiding foods that may upset your stomach can help you stay up past your bedtime. During the night, grabbing small nutritious snacks can provide much-needed energy and allow for breaks. 

If you have the opportunity to rest before the exam, taking another brief nap may be useful. Anything longer than a nap may make it harder to get back to your regular sleep schedule. Your best bet for getting your sleep back on track is to go to bed at your usual time the evening after the all-nighter (or a bit earlier) and wake up at your usual rising time the next morning. 

If you find yourself frequently occupying the late hours of the night with schoolwork, you may also find it helpful to implement new time management strategies. Using these strategies will hopefully minimize the need to pull all-nighters in the future. You may consider exploring time management strategies such as identifying high-priority tasks and spreading out your study time, rather than cramming all at once. As a student, your school or university may offer specific support, like health education, coaching, or support groups for improving time management skills that may be worth checking out. 

With thoughtful planning, support, and determination, your dreams of getting that good grade and getting good sleep can become a reality!
