The complete guide to waking up as a heavy sleeper
If you've spent years assuming you're just "bad at mornings," this guide is for you. Being a heavy sleeper isn't a character flaw, and it isn't something more coffee or more willpower fixes. It's a specific, understandable set of reasons your body doesn't respond to a standard alarm the way other people's do — and once you understand which of those reasons applies to you, the fix usually gets a lot simpler.
This guide pulls together everything on the site into one place. Read it top to bottom, or jump to the section that matches your situation.
Start here: what's actually going on
Before troubleshooting anything, it helps to know what "heavy sleeper" actually means, because it's not one single trait.

- How Much Sleep Do You Actually Need? is worth ruling out first — some "heavy sleeper" symptoms are really just chronic sleep debt in disguise.
