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.

The parts of college that work against a student’s sleep before they have made a single choice.

Original research

Stress and sleep

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.

The comparison

Online College Sleep Programs vs. Sleep Supplements: Which Actually Moves the Needle?
