Holed up in your room, the minutes are dripping by. Maybe you could’ve done it earlier, but this deadline surprised you. Now, in a few short hours, you have a test or a major assignment, and you’re realizing that sleep is no longer on the table. This is a feeling all too familiar to many students, and needless to say, it’s not a fun experience. But what happens tomorrow? How much will your performance suffer from lack of sleep? If you ask me, I wouldn’t worry too much.

Sleep is undeniably important. According to Johns Hopkins Medical, most teens need 9-10 hours every night (good luck with that) for basic upkeep, as well as to support their immune system, and help with brain development. Teens, who are in a naturally accelerated time for intellectual, physical, and emotional growth, have an especially important need to get their beauty rest. In order to learn, retain, and remain healthy, you must have a regular, healthy sleep schedule with few deviations. However, the adverse effects of sleep deprivation are mostly on the long-term scale. For example, if you sleep an average of 5 hours a night over a few months, you are more likely to get sick and stay sick, it will be harder for you to learn at school, and come test day, your score will likely reflect that. In the short term, however, the effects of sleep loss, say after one bad night, seem less dire.

I posit the theory that sleep loss does not adversely affect scholastic performance (at least in the short term). I can tell you from one too many firsthand experiences that it truly sucks to drag yourself to an 8:30 AM test room when you were up until 3:30 AM trying to study for it. I can also tell you that it has not noticeably hurt my scores compared to when I am well rested. This seems to be somewhat consistent with the students’ opinions on the topic. Of 24 students polled, 15 (62%) claimed they saw no difference in academic performance the day after a poor night of sleep.  Obviously, not everyone agrees, but a significant portion of our population can function near 100% on suboptimal sleep.

But how is that possible? The human brain and body are more resilient than you think. When you deprive yourself of sleep, your brain senses it as ‘active danger.’ Essentially, the primal brain sees only one reason not to go to sleep, and that is that you are being actively chased. Accordingly, it gives you all the necessary boosters to keep running. According to the Scientific American, a single night of lost sleep acts as a stressor, triggering survival mode in which your brain triggers the adrenal gland to flood your system with adrenaline and cortisol, as well as causing the liver to release more sugar into the bloodstream. This allows a sleep-deprived person to feel somewhat normal or even have a burst of energy for a few hours. And those who feel their performance slip may be falling victim to the placebo effect. It is, however, important to note that once this initial burst wears off, the subject is likely to crash as they still have not slept. (But hey, if you’re done with the test, you’re golden).

This brings me to everyone’s favorite solution to life’s hardships: Caffeine. Caffeine works by blocking adenosine receptors. Adenosine, according to the same Scientific American article, is a chemical in your body that is responsible for the urge to rest. When caffeine blocks adenosine from its receptors, it literally blocks you from feeling tired. This can be very helpful for someone trying to get through the long day after a long night. As far as I am concerned, in moderation and in the right setting, caffeine is a godsend and can help you take your second wind and finish your day strong.

Caffeine, however, is not a substitute for sleep; it is not magical energy. It covers the symptoms of fatigue, but it does not deal with the underlying need for rest. I say this because it can be easy to create habits of sleep deprivation and its coping mechanisms. In a poll, 15 of 33 Boulder High students say that they consume caffeine every day. This in of itself does not indicate a problem as long as the relationship is not one of reliance; however, it does pose the question of why so many students are drinking so much caffeine, and I would encourage anyone who uses the stimulant regularly to take a look at their sleep schedule and avoid a deficient schedule and the ailments arising from long term sleep deprivation.

There is no substitute for good sleep, and I would never suggest that anyone purposefully mess with their natural rhythm. This being said, next time you are in a pinch, and the all-nighter calls to you, take a deep breath, keep calm, and study on; you will be fine…t’s just not that big a deal.
