It's 11:40pm, you have 63 pages of notes left, and you've read the same paragraph on the Krebs cycle four times. Knowing how to stay awake while studying is mostly about the room you sit in and how you use each hour: a desk instead of a bed, the overhead light on, short blocks with real breaks, and testing yourself instead of rereading. This is for solo sessions at a desk, from after dinner to the late push before a deadline.
Work in 50-minute blocks with a proper break
Long, flat stretches of the same task are where attention drains away. In a 2011 study in Cognition, Atsunori Ariga and Alejandro Lleras at the University of Illinois gave 84 people a dull 50-minute computer task. Most of them got worse as the task went on. The group that was briefly switched to a different task twice during those 50 minutes showed no drop at all.
Plan the night in blocks. Set a timer for 45 to 50 minutes, work on one topic, then take 5 to 10 minutes completely away from the screen. Stand up and refill your water. Then start the next block on a different chapter or problem set, so your head gets a change of task as well as a change of position.
Get off the bed
Studying in bed feels comfortable for about twenty minutes. Then the pillow wins. Sleep clinicians have known this since 1972, when psychologist Richard Bootzin published stimulus control, a set of instructions for people who struggle to sleep. The first rule, as it appears in the University of Pennsylvania's behavioural sleep medicine protocols, is to use the bed for nothing except sleep: no reading, no TV, no eating in bed. The same protocols use studying as their example, because studying in bed tends to end with falling asleep.
Sit at a desk or a kitchen table with a hard chair. Feet on the floor, screen at eye level.
“Definitely energized.”
How to stay awake while studying at night
Turn on the big light. A desk lamp in a dark room is cosy, and cosy is what you're fighting. In a 2000 study in Behavioural Brain Research, Christian Cajochen and colleagues exposed volunteers to light levels from 3 to 9,100 lux during the early night. Brighter light meant fewer slow eye movements and lower self-rated sleepiness. About 100 lux, ordinary room lighting, produced half of the alerting effect seen at 9,100 lux. Ceiling light plus desk lamp is the easy version.
Keep the room on the cool side and keep a glass of cold water on the desk. When your eyes start to sting, splash cold water on your face at the sink and come back.
Stop rereading your notes
Rereading is the most sleep-inducing way to study, because your eyes move while your brain coasts. Close the book and pull the material out of your head instead. In 2006, Henry Roediger and Jeffrey Karpicke at Washington University in St. Louis had students study a prose passage and then either reread it or take recall tests on it. A week later, the students who had tested themselves remembered 61% of the passage. The rereading group remembered 40%, even though they had read the passage about 14 times against roughly 3.4 times for the testing group.
Recall is also harder work, and hard work keeps you awake. Some ways to do it at 11pm:
- Cover your notes and write down everything you remember on a blank page, then check.
- Turn each heading into a question and answer it out loud.
- Do past paper questions with the book closed.
How to stay awake while reading
Read with a pen in your hand. Write one line in the margin at the end of every page saying what it was about. Read the hardest pages standing at a counter, or out loud.
Ten minutes on the stairs
When your break comes, move. Researchers at the University of Georgia tested this in 2017 with female college students who slept under 6.5 hours a night. Ten minutes of walking up and down stairs at an easy pace, about 30 floors, left them feeling more energized than a 50 mg caffeine capsule, roughly the caffeine in a can of soda. The caffeine did little more than the placebo. Without stairs at home, walk around the block, or do two minutes of squats in the hallway.
How to stay awake while studying without caffeine
Coffee at 10pm is a loan against tomorrow. Dragon Breath is what we'd keep next to the laptop instead.
It's a 50 ml mouth spray of chilcuague extract. Chilcuague (Heliopsis longipes), also called golden root, is a root from Central Mexico. At the end of a block, before you open the next chapter, spray once into your mouth. It tastes earthy and a little peppery for a second. Within about 10 seconds a bright electric buzz spreads across the tongue and mouth, then your mouth floods with saliva. A clean, fresh feeling lingers after it. You sit back down switched on, and the next page gets read properly.
In one reaction video, a customer tried a single spray and, moments later, said: "Definitely energized."
The bottle sits next to your highlighters and makes no mess, and a few sprays is all a long night takes. One bottle holds 250+ sprays, which covers a lot of late nights before finals. The extract stays sealed in Miron violet glass, away from air and light, which keeps it fresh in a way a bag of loose root or powder can't. Start with one spray. Once you know the feeling, you can go up to five. Our guide covers where chilcuague grows and how the root is used in Mexico.
Dragon Breath – Chilcuague Extract
50 ml mouth spray. Wild-harvested chilcuague root, dual-extracted. 250+ sprays.
Add to bagIf your eyes keep closing, nap for 26 minutes
A short nap beats an hour of nodding over the same page. In NASA's 1995 study of long-haul pilots, those who napped for about 26 minutes during the flight showed up to 54% higher alertness and up to 34% better performance than pilots who didn't nap. The Sleep Foundation's advice is to keep naps under 30 minutes, since longer ones are more likely to leave you groggy.
Set an alarm for 30 minutes, which allows a few minutes to fall asleep. Nap in a chair or on the sofa, away from your bed. When the alarm goes, stand up straight away, turn the light back on and start a fresh block. For the morning itself, our guide on what to do before an exam covers the hours before you walk in.
Dragon Breath considerations
Our recommendation: if you're pregnant, nursing, taking medication, or allergic to plants in the daisy family, ask your doctor before using it.
Questions students ask
Why do I get sleepy as soon as I start studying?
Sitting still with one slow task is the setup Ariga and Lleras found wears attention down. Soft light and a bed make it worse, so move to a desk, turn the room light on and break the work into blocks.
Is it better to study late at night or wake up early?
Pick the one you can do without cutting into sleep. A late session goes better at a bright desk with a timer running.
How long should a study break be?
Five to 10 minutes after a 45 to 50 minute block, away from the screen. Use it to walk, climb stairs or get water.
When should I use Dragon Breath during a study session?
Between blocks, as you sit back down. One spray, and the buzz arrives within about 10 seconds.
