It is the start of university, you are already on your fourth themed night out of the week, and you have signed up for every society on campus. Your relationship with your bed, it turns out, is what determines whether you keep up with any of it — including the reading list.
Start with when you get up
"If you can get out before 11am-ish then there's a part of the brain, just behind the eyes, that responds to light," says Jo Baker, a psychotherapist and student sleep and mental health expert.
"Getting daylight early on in the day is really going to help to keep your body in check. How you sleep at night starts with how you wake up in the morning."
Sleep is essential to learning and absorbing information. But late nights, noisy flatmates and a strange new bed can push good habits out of reach fast.
Why the obvious fix fails
Forcing yourself to have an early night will not work, Baker says — especially if you end up lying wide awake.
"Your brain learns this is somewhere I lie and get stressed about not being able to sleep — so the most important thing is a consistent waking time."
Anna-May, 20, does a four-hour round trip from Kendal in Cumbria to study dance at the University of Salford, and gets about five hours a night with the alarm at 05:00. Her account contains the trap exactly: "I track my sleep and get worried about how little I will get, and then sometimes that keeps me up."
And when you feel groggy it is tempting to drink coffee all day. Caffeine hangs around in the body and blocks the build-up of sleepiness — the pressure to sleep that accumulates through the day. Drinking it in the afternoon does not just delay sleep that night; it removes the signal you need in order to fall asleep at all.
What it means in Bangladesh
The Bangladeshi version of this problem is not four nights out a week. It is admission coaching, a 6am class, a commute across Dhaka, and a culture in which staying up all night to study is treated as a virtue rather than a cost.
The evidence on that last point is unambiguous and worth repeating to every HSC and admission candidate: sleep is when the day's learning is consolidated into memory. An all-nighter before an exam trades away the process that files what you studied. Students who sleep less do not learn more; they learn less and feel worse while doing it.
Three pieces of Baker's advice transfer without modification. A consistent wake time, including at weekends, does more than any other single change — and it is the one piece of sleep advice that costs nothing in a shared room. Morning light is free and abundant here; ten minutes outside or on a balcony before the day starts anchors the whole cycle. And if you cannot sleep, get out of bed rather than lying there, so your brain does not learn that bed is where you lie awake worrying.
The caffeine point needs adapting rather than importing. The relevant drinks in a Bangladeshi student's day are tea and energy drinks, and the energy drinks are the problem — a single can can carry as much caffeine as two or three strong cups, and they are marketed to exactly the people who should not be drinking them at 10pm. The practical rule is nothing caffeinated after mid-afternoon.
