College sleep and more.
College Wrecks Your Sleep developed the College Sleep Hacks™, an online sleep program for college students: 25 Sleep Hacks that provide information, then advice, so students can decide what changes work best for them.
The blog is a resource for students and parents adapting to an environment engineered against sleep — and sleep shapes their grades, their friendships, and how much of college they enjoy.
College and Sleep
The parts of college that work against a student’s sleep before they have made a single choice.
University Dorm Temperature Policies Are Set Too Warm for Sleep
Heating targets clustered at 68–72°F and cooling at 72–76°F. Every policy but one sits above the range that supports sleep — and at some schools, neighboring rooms vote on the temperature.
How to Get Better Sleep at School
Why the supplement aisle is the wrong place to look, what college actually changes about your sleep, and the fixes that survive a shared room.
Why Doesn’t Standard Sleep Advice Work in College?
The four tips everyone gives, why they don’t survive a semester, and the fact that actually replaces them.
What Does College Actually Cost in 2026?
Published prices, what families actually pay, and the per-hour number nobody calculates.
Students and sleep
What the research shows about how much students sleep and what it costs them.
Does More Sleep Actually Improve College Grades?
A randomized experiment with 1,149 students found that 19 extra minutes of weeknight sleep raised semester grades — the first causal evidence that improving sleep improves academic performance.
How Does a Lack of Sleep Make College Stress Worse?
Sleep loss raises amygdala reactivity by over 60% and weakens the brake that regulates it — and in students, sleep predicts next-day stress more strongly than stress predicts sleep.
How Much Sleep Do College Students Actually Get?
103,639 students surveyed: 42.6% sleep six hours or less on a weeknight, and only 9.1% felt rested on most days of the week.
What Happens When You Pull an All-Nighter?
The hour-by-hour physiology of a night without sleep, the academic cost the research actually shows, and what to do instead.
How Does Sleep Affect College Grades and Friendships?
The six-hour cliff, why a tenth of a GPA point can be worth everything or nothing, and why sleep loss spreads loneliness through a dorm.
Sleep Supplements
What the evidence supports, what it doesn’t, and what is actually in the bottle.
The Truth About the Risks of Melatonin for College Students
Across 79 studies there was no increase in serious adverse events. The real problem is different: students take 5mg an hour before bed, treating a timing signal like a sedative.
What Are the Downsides of Melatonin?
Next-day grogginess, doses that backfire, and supplements measured at 83% below to 478% above the label — plus the bigger problem underneath.
Do Sleep Supplements Work for College Students?
We built a sleep supplement and killed it. Melatonin, magnesium, glycine, and the one ingredient with real evidence — and its asterisk.
Online College Sleep Programs
What a student can actually enrol in, what each kind costs, and who each one is built for.
Online College Sleep Programs vs. Sleep Supplements: Which Actually Moves the Needle?
Melatonin buys about seven minutes. The magnesium hype traces to a 12-person study. Meanwhile the behaviors that wreck college sleep — caffeine timing, alcohol, the weekend wake shift, a warm dorm — have far more room to move.
Online Sleep Programs for College Students
Free university programs, general courses, digital CBT-I and apps — what each kind is, what it costs, and which students it is built for.
